[obsah] => The Department of Water Technology and Environmental Engineering (DWTEE) is a part of the Faculty of Environmental Technology of the University of Chemistry and Technology, Prague. The Department provides education in Czech and English and is active in the research field related to water technology. Currently, there are approximately 40 master students, 30 PhD. students and 24 staff members at the department. Many of the research projects run at the department are done in cooperation with companies and other research institutions. The department is involved in two International Erasmus Mundus study programmes: The International Master of Science in Environmental Technology and Engineering (IMETE) and the PhD. program Enviromental technologies for contaminated solids, soils and sediments (ETeCoS3).
The Department of Water Technology and Environmental Engineering has 6 informal working groups covering all topics regarding water technology, chemistry, and biology: Anaerobic Technologies, Biological Wastewater Treatment, Hydrobiology and Microbiology, Physical-Chemical Wastewater Treatment, Aquatic Chemistry and Analytics, and Drinking Water Treatment. The research interests of these groups is often shared and they cooperate with each other on scientific work and education. The department cooperates with many institutions and companies from the Czech Republic as well as from other countries.
DWTEE has a long standing history of cooperation with various international professional associations. Professor Vladimir Madera, the Head of the Department at that time, was one of the founding fathers of IAWPRC, the predecessor of International Water Association (IWA). In 1988, Prof. Grau (Head of the Department after Prof. Madera) was elected IWA's Vice-President; in 1990-1994, he served as the Association's President. Members of the DWTEE are active in the following IWA specialist groups: Anaerobic Digestion; Design, Operation and Costs of Large Wastewater Treatment Plants; Microbial Ecology; and Water Engineering (former Activated Sludge Population Dynamics). DWTEE also cooperates with the European Water Association (EWA), where Professor Jiri Wanner was President between 2005-2007.

→ International Study Programmes
DWTEE cooperates in two Erasmus Mundus international study programmes. For further information, contact Prof. Pavel Jeníček or Dr. Jan Bartáček.
The International Master of Science in Environmental Technology and Engineering (IMETE) programme is an International Erasmus Mundus programme. It trains people to apply and develop environmental technologies, offering a wide range of optional study fields in an international environment. IMETE is offered by a consortium consisting of three leading Higher Education Institutes: Ghent University (UGhent, Ghent, Belgium), UNESCO-IHE Institute for Water Education (UNESCO-IHE,Delft, Netherlands), and University of Chemical Technology, Prague (UCT Prague, Czech Republic). Student mobility within Europe is an integral part of the programme, which contains 120 ECTS (2 years). During the programme, students study in Delft (Netherlands), Prague (Czech Republic) and Ghent (Belgium). Master thesis research is carried out in one of these locations or at one of the many associated partner institutions all over the world. Between the first and the second years, summer school is held. More information here.
The Environmental Technology for Contaminated Solids, Soils and Sediments (ETeCoS3) programme provides education and research at the PhD level, training its doctoral candidates to think globally and co-work in multidisciplinary research teams. It is delivered by three universities: University of Cassino (Italy), UNESCO-IHE Institute for Water Education (Netherlands), and Université Paris-Est (France). The programme is centered around three key topics in environmental pollution: Heavy metals, recalcitrant organic pollutants, and contaminated solids. The programme focuses on fundamental and applied aspects to treat and remove these pollutants as well as on the development of recovery and reuse technologies with market potential. There will be a close connection to practical problems, as e.g. hot spots in the Balkans, brown fields in the Czech Republic, and sediments and soils polluted by mining activities in Minais Gerais (Brazil). UCT Prague (represented by the Department of Water Technology and Environmental Engineering) is an associated partner of the consortium.
→ Expert Associations
The Czech Water Association (CzWA) was formed in 2009 from the previous Association of Wastewater Treatment Experts (ACE CR). The CzWA is an independent non-governmental and non-profit organization promoting the sustainable and improved management of the total water cycle. The CzWA is a national member for the Czech Republic in the European Water Association and in the International Water Association.
The International Water Association (IWA) is a global reference point for water professionals, spanning the continuum between research and practice and covering all facets of the water cycle. Through its network of members and experts in research, practice, regulation, industry, consulting and manufacturing, IWA is in a better position than any other organisation to help water professionals create innovative, pragmatic and sustainable solutions to challenging global needs. Members of DWTEE are active in the following specialist groups of the association: Anaerobic Digestion; Design, Operation and Costs of Large Wastewater Treatment Plants; Microbial Ecology; and Water Engineering (formerly Activated Sludge Population Dynamics).
The European Water Association (EWA) today represent most European countries. The main goal of the association is to create a forum for the mutual information exchange in all aspects of water pollution control in general and of wastewater collection, treatment and disposal in particular. EWA provides professional service to the European Commission in matters dealing with water pollution control and consultancy of water legislation. The Czech Republic became a member of EWA in May 1997. The activities of EWA in the Czech Republic are organized and co-ordinated by the Czech Water Association (CzWA). Professor Jiri Wanner from DWTEE was EWA President between 2005-2007.
The World Toilet Organization (WTO) is a global non-profit organization committed to improving toilet and sanitation conditions worldwide. WTO is also one of the few organizations to focus on toilets instead of water, which receives more attention and resources under the common subject of sanitation. Founded in 2001 with 15 members, it now has 235 member organizations in 58 countries working towards eliminating the toilet taboo and delivering sustainable sanitation. Professor Jiri Wanner is a member of the WTO.

Project goal:
The project aims to assess various advanced oxidation processes (AOPs) for the treatment of difficult to treat industrial wastewater. Subsequently, the wastewater will be purified by means of a membrane biological reactor (MBR), which guarantees a high outflow quality. To carry out laboratory and operational tests, a pilot plant model with AOP and subsequent MBR will be installed (fitted) at the selected location. Several AOPs based on the use of UV radiation, ozone and hydrogen peroxide will be evaluated in the project. The long-term operation of the plant will evaluate the efficiency of AOPs, the efficiency of the biological process, the development of permeate quality, the economic and energy balance, and the utilization of purified waste water for recycling.

- Characterization of ladderanes and their membranes
- Research of ladderanes potential applications
Abstrakt:
Anammox bacteria are standardly applied in the wastewater treatment process for the removal of nitrogen. Their waste biomass and other sludge compose a great amount of waste from the treatment plants and its further utilization or recycling is often problematic. However, unlike other bacteria, anammox contain unique lipids in their membranes, the ladderanes, which characteristics are still not sufficiently explored. Therefore, this project is devoted to the cultivation of anammox bacteria, the isolation and characterization of ladderanes, and research on their possible applications in the chemical or pharmaceutical industry. The ultimate goal is to recover the waste anammox biomass and turn it into a high-value product, a source of ladderane phospholipids.

Project Objective
The overall objective is to facilitate industrial symbiosis by co-development of a roadmap towards wider uptake of water-smart solutions for wastewater reuse and resource recovery.
Specific objectives
To demonstrate innovative technical solutions that optimize water reuse and resource recovery in selected industry settings by:
- Demonstrating safe use of treated effluent for irrigation purposes in grey-green solutions for urban development with reasonable water transportation expenses.
- Developing and applying monitoring and control schemes to adequately manage the health and quality risks associated with reuse of treated wastewater and recovered resources.
- Optimization of the value chains to quantify the improved resource efficiency and economic benefits, also with respect to future applications.
Abstract
WIDER UPTAKE will demonstrate innovative solutions for wastewater reuse and resource recovery where market utilization of the recovered resource(s) (water, nutrients, materials, energy) is achieved through a symbiosis between the utility and industry. WIDER UPTAKE will apply a case study approach that will provide applied knowledge on the operationalization of the solutions in a range of socio-economic, environmental and climatic conditions. The case study approach will cover different situations with regards to the availability of water resources and what type of resources e.g. nutrients, biosolids, energy that are in focus for recovery. The scale and maturity in the development of the water-smart symbiotic solutions will also differ between the case studies allowing for the sharing of knowledge and identifying best practices at different stages of implementation.

Project objectives:
The aim of the project is to create chemical and technological conditions for the recycling and reuse of purified urban wastewater and where it is possible to replace so far usage of expensive drinking water for non-drinking purposes. The reused water will be utilized mainly for agricultural and other irrigation, irrigation for lawns of sports grounds (golf, football, etc.), urban greenery, service water for maintaining the cleanness of towns and municipalities. After measurements in the laboratory, proposed operations and their combinations are tested at the pilot scale in the form of a module, treating the effluent from the current water line in the Central Wastewater treatment plant in Prague.
Specific objectives:
The specific aim was a proposal of the composition of laboratory devices for testing of the technological arrangement of the water treatment line, treating the effluent from CWWTP to water suitable for irrigation, and realization of testing the particular variations of technological arrangements in pilot scale. The economic intention is to produce cheaper service water than potable water, often used for these activities. The non-economic aim is the conservation of natural sources – i.e. the raw groundwater and surface water resources used for potable water production.

Motivation:
In recent years, eutrophication has proven to be a serious threat to water bodies. Excess of nutrients in surface water causes increased growth of cyanobacteria, which further causes a reduction of dissolved oxygen, death of fish due to suffocation and complicates processes of water treatment for further use. The deteriorating quality of water resources is directly related to human activities. One of the main sources of nutrients in water is effluent from municipal wastewater treatment plants. Therefore, it is necessary to pay attention to this problem and try to develop new or improve existing methods of nutrient removal in municipal wastewater treatment plants, especially forms of phosphorus, and thus work to improve the quality of water resources.
Project Objective:
The main objective of the Project is the introduction of environmental technologies into the wastewater treatment processes (WWTP) with the aim of reducing the hazardous phosphorus impact on the environment especially in the water protection sphere, and/or minimizing the risks of the negative influences of this pollutant on living organisms including human health. It is specifically, research and development of technologies focused on the tertiary treatment of wastewaters using the nanofibers technology. The main goal of this Project is obtaining a utility model – MEMFOS system and functional sample. The MEMFOS system will find the application at wastewater treatment plants whose outflows will be required to show total phosphorus concentrations in micrograms.
Specific objectives:
In the area of tertiary wastewater treatment, the Czech Republic does not use technology that would ensure microgram values of phosphorus in effluent neither technology using nanomaterial. Due to the planned changes in the law, will be required a reduction of concentration of phosphorus in the effluent from WWTP. It is necessary to respond to this requirement, i.e. find a solution and thus be prepared for the emerging market in the water sector. The solution procedure includes the following points:
- Laboratory testing of the behavior of existing nanomaterials by using the effluent from wastewater treatment plants with subsequent modification of the material so that that material can be used as a main functional element for the MEMFOS pilot plant.
- Design of the MEMFOS pilot plant.
- Construction of the MEMFOS pilot plant.
- Testing of the MEMFOS pilot plant.
- Optimization of operations of MEMFOS pilot plant.

Project goal:
The goal of the project is finding of technological parameters and the bioreactor configuration for biological conversion of carbon dioxide to biomethane, which is transportable by the natural gas grid. The project comprises a determination of cultivation conditions of hydrogenotrophic methanogens, an introduction of hydrogen to the system, finding of bioconversion limits during hydrogen dosing to the external bioreactor or directly to the anaerobic fermenter. Further different possibilities of an application in the technology of biogas production will be evaluated. This approach enables to exploit existing technological and energetical infrastructures of biogas plants and wastewater treatment plants and the implementation could be very fast.

Design a unit for removing micropollutants and antibiotic resistance genes from small water sources of drinking and wastewater.
Abstract:
The project responds to two global problems: the spread of antibiotic resistance genes (ARGs) and the general pollution of the environment by micropollutants (drug and pesticide residues). The growth of antibiotic resistance is a complex problem and these days it is one of the greatest civilization threat. Many micropollutants have already been shown to have negative effects on aquatic and soil organisms that can significantly disrupt the affected ecosystem. This contamination can have a direct and indirect impact on human health. The micropollutants are commonly found in wastewaters, however, wastewater treatment plants (WWTPs) were not designed to remove them. Treated wastewater is a potential source of water for further application, but care must be taken to avoid the spread and accumulation of ARGs and micropollutants, e.g. by using contaminated water for crop watering. The Czech Republic will have to adapt in the near future to new Regulation of the European Parliament and of the Council on minimum requirements for water reuse, which is currently under preparation. The main objective of this Regulation is to mitigate the causes and consequences of water scarcity throughout the EU. This project focuses on the treatment of wastewater from smaller local sources, such as a small WWTP or recreational facility with a domestic treatment plant, with the aim of potential reuse of these waters for utility purposes. Furthermore, the system will be optimized for the recovery of local underground sources of drinking water contaminated with pesticides from agricultural activities. This enables to use it in areas with a lack of (high-)quality water for housing, recreation, and services.

- Determination of health risks and risks to the environment.
- Use of Internet of Things (IoT) technologies.
Abstract:
The most common objection to the gray waters recycling is that these waters contain harmful substances or the environment and may affect health or the environment. In practice, integration into technical building equipment (TZB) as well as integration into the public water supply and sewerage system (disputes concerning the payment of sewerage and connection to the water supply network from which the water used) has not yet been resolved or is not verified in practice.
The aim is to design and verify several solutions for recycling gray waters, to identify health risks and risks to the environment. Based on the results, propose suitable solutions with respect to the purpose of use. Furthermore, technically solve the objection, connection to public water supply and sewerage, using the Internet of things (IoT) technology.

The energy of the organic compounds contained in wastewater and sewage sludges can be recycled using anaerobic technologies, i.e. anaerobic digestion (AD). Biogas (mixture of methane and carbon dioxide), which is the end product of anaerobic digestion, can be further utilized as a source of electricity and heat. The AD process is especially favorable for its low green house gasses production.
Work group Anaerobic Biotechnology deals with optimizing the AD processes and solving some specific problems inherent to AD such as removing (recycling) nitrogen and sulfur compounds released in the AD process. The work group aims to protect natural resources (clean water, fossil energy sources or atmosphere) through employing clean anaerobic technologies.

Research areas
Energetically Self-sufficient Wastewater Treatment Plant
The work group Anaerobic Biotechnology has a long-term interest in anaerobic digestion of sewage sludges at wastewater treatment plants (WWTPs). The goal of this effort is energy recovery from sewage sludges in order to cover most of the energy consumption of the WWTP. As an example, the central WWTP in Prague is energetically self-sufficient by almost 90 %. This was achieved by introducing sludge disintegration in thickening centrifuges, introducing thermophilic AD process, improving mixing in digestors and intensive precipitation of the particulate organic matter contained in the incoming wastewater. Applying these measures, we achieved two-fold increase of biogas production at WWTP Prague.
Optimizing anaerobic fermentation of lignocellulosic materials by using anaerobic fungi
The numbers of biogas stations have recently been quickly rising throughout the Europe. In these biogas stations, energy crops, agricultural wastes and other types of organic wastes are transformed to biogas - an alternative source of green energy. Unfortunately, lignocellulosic material (plants and their debris) treated in the biogas stations is not readily degradable: only 40–60 % of the total organic matter can be transformed to methane in the classical AD process. This problem can be solved using anaerobic fungi capable of degradation of cellulosic materials. In nature, these microorganisms occur in rumens of ruminants such as cow or deer, where they help these animals to degrade lignocellulosics. By introducing anaerobic fungi into anaerobic digesters, methane production of the biogas plants can increase by up to 20 %.
H2S removal from biogas
H2S is source SO2 emissions, odour problems and operational problems during burning biogas in cogeneration units. Therefore, it is crucial to remove H2S from biogas. Biological methods for H2S removal from biogas are based on H2S oxidation to elemental sulphur by chemolithotrophic bacteria:
H2S + 0.5O2 --> S0 + H2O
This process can take place in external bioreactor following H2S scrubbing from biogas. It can also be induced inside the anaerobic reactor by introducing small amount of oxygen – so called “microaeration”. Both processes are efficient and our results have shown that microaeration has additional positive effects on the AD process such as better hydrolysis of organic compounds. In general, biological methods for H2S removal are always cheaper and simpler than physical-chemical H2S removal.
Nitrogen removal from liquid effluents from anaerobic digesters
The effluents from anaerobic digesters often contain high loads of ammonium nitrogen. At high concentration, ammonium nitrogen can inhibit the anaerobic digestion (AD) process and, when treated at WWTP, it considerably increases the nitrogen load at the WWTP. Compared to the common nitrification/denitrification process, the nitritation/denitritation process can significantly decrease the consumption of oxygen (by 25 %) and organic substrate (by 40 %) needed for ammonium removal from the liquid phase. Therefore it is intensively studied at our work group. Next to this, we also study methods for nitrogen removal directly from the anaerobic digester, e.g. by sorption on zeolites.

It deals with the issues of nutrient removal, particularly nitrogen and phosphorus, including various ways of bio-augmentation.
An important part of the work consists in sludge analyses mainly with respect to separation properties of the sludge and the presence of specific metabolic groups of organisms. This also involves molecular biology methods such as FISH or PCR-DGGE.
The group also engages in forming mathematical models for wastewater treatment plants and proposing optimisation of their management and operation.
Hydrobiology and microbiology are significant in: assessing the ecological state of steady and running waters, studying eutrophication and acidification, evaluating the state and efficiency of water management and treatment technologies as well as for operations with cooling water.
Microorganisms can indicate both the processes that are in progress and the efficient technological conditions or status but they can also be used for biotechnological purposes. Selected microorganisms are even used in laboratories or semi-operations to detect the efficiency of newly introduced materials, agents and intermediates.
In this respect, biology mainly focuses on applying theoretical knowledge and its utilization to indicate the status of processes. Results of biological analyses should enable a technologist to draw relevant conclusions and take effective measures. What is also important is the legislative framework where the knowledge from biological fields is implemented. The future of biology lies in the application of molecular biology methods (PCR, DGGE etc.). All the methods are applicable both in teaching and laboratory practice. Another advantage is the connection of undemanding microscopic methods with cultivation methods and the methods carried out on a purely molecular-biological material.
Effects on microclimate, air quality, water and soil ecosystems within the scope of hydric recultivation of brown coal mines.
Extensive hydric recultivation, flooding the residual pit of the Most – Ležáky quarry executed within the scope of revitalising the area affected by mining will significantly improve the countryside characteristics north of the Most city. The aim to recultivate brown coal mines is a subject to the assessment of environmental impacts (EIA). The objective of this assessment is to identify, describe and evaluate the expected effects of the projects being prepared (buildings, activities and technologies). The result of the project will consist of the complex methodology quantifying environmental impacts of brown coal mines recultivation. In accordance with the framework regulation for water management 2000/60/ES the assessment of the local environmental status is performed mainly on the basis of water and periphyton samples (the main components being plankton and benthos).
Importance of drinking water quality degradation occurring in its transport and accumulation
Drinking water will be safe in the whole supply system only if contamination of water resources is prevented, water is treated sufficiently (the pollutants present are removed completely or partially to comply with requirements for quality and safety of drinking water) and also the secondary contamination is prevented during drinking water accumulation and distribution and operations with it. Water tanks and towers as buildings cannot be substituted in the water supply system and they also largely contribute to the reliability of the system, its maintainability or vulnerability. These buildings are strategically significant and can influence the water quality. Their location also greatly affects economical costs of the water supply system and its operation.
Aspects for assessing the impact of water tanks on the quality of the water supplied were solved to define both external and internal factors which crucially influence the water quality and its stability in accumulation tanks as well as in the distribution network. There were identified different levels of importance of partial causes affecting the quality of treated, accumulated and transported drinking water, which was a significant step allowing us to focus on the most effective methods minimizing the formation of biofilms, present biological life in water tanks and towers and to specify the rules for exchange of water in accumulation tanks. A prototype of a filtration device was developed to be placed into venting shafts in water tanks. Technical directive I-D-48 Construction arrangement, operation and maintenance of water tanks was prepared during the project solution and it became the basis for the efficiency verification of the directive of ČSN 73 6650 Water tanks, which applies to the design and operation of water tanks (both of the ground and tower types, which are the components of the water network supplying the public with drinking water).
Currently, the issues related to biologically stable drinking water are being researched further in accordance with Plans for Drinking Water Safe Supply (Water Safety Plans) and hazard analysis (HACCP).
Research of nanosurfaces
This workplace belongs to the NANOPIN research centre. In its biological section it implements the methods testing material surface properties (applied on glass, fabrics, pipelines in contact with water). Currently, a directive is being prepared dealing with testing the antibacterial properties of nanosurfaces. Simple methods testing material surface properties will be then put into practice.
Tested materials will also include filtration materials that are expected to become a part of filters used in water treatment operations.
New materials and technologies for material conservation of historical monuments and preventive monument care.
The project goal is to develop new materials and technologies and to verify their functionality for the following purposes: efficient but gentle removal of unwanted secondary layers from material surfaces, mainly the layers of oils and polymers; consolidation of construction monuments damaged by weathering and impregnating the porous inorganic substrate with innovated solidifying materials; preventive protection of materials forming the monument surface against weathering effects, namely water, and against biodegradation by applying new hydrophobic and biocidic agents. Newly developed materials and technologies will focus on the increased efficiency and care of applications with regard to the materials treated and the environment, prolonged lifetime, reversibility and the quality of processes comprising monument preventive, restoration and conservation actions. The development stage is to implement new knowledge from the basic material research, mainly nanomaterials and nanotechnologies including their combinations with traditional materials and methods. The research focuses on solving the tasks of the topical priority Materials and technologies for protection and preservation of cultural heritage of the NAKI Program.

he can never control it, but he must always protect it ...
Drinking water occupies a privileged position among the foodstuffs that a person needs for his life. For this reason, it is necessary to pay increased attention to its quality. In simple terms, we could understand this only in relation to the production of drinking water, ie the individual technological steps and procedures that are used in its production and should provide high-quality drinking water with an optimal composition. In relation to the quality of drinking water required by the consumer, however, this issue moves to a much broader level, starting with the protection of water resources, continuing our own technology of drinking water production, but also its distribution to the consumer. Only by controlled professional intervention in these three areas can the desired goal be achieved - quality drinking water. All these areas are the subject of the focus of our working group.

The chemical behavior of inorganic substances and new PPCPs depends on their chemical structure. A common type of water analysis usually determined the total concentration of individual components. In fact, the individual components occur in various forms of existence (species), which result from protolytic, complex-forming, oxidation-reduction, polymerizing, and biodegrading reactions. It is difficult to determine the individual forms experimentally and so they are frequently calculated on the basis of chemical thermodynamics laws. For this purpose, a range of calculation programs already exists.
Hydroanalytics
Development and extended applications of various new PPCPs require the preparation of suitable analytical methods for their identification and quantification. Among the methods, applicable belong particularly the methods of instrumental analysis allowing detection of the presence of the PPCPs selected even at nanogram concentrations. Attention is primarily paid to selected medicaments, cosmetic preparations, and surfactants. The researchers closely cooperate with the Czech Office for Standards, Metrology, and Testing (ÚNMZ) in creating new regulations ÈSN. They also deal with the assessment and adaptation of new hydro-analytical directives ISO and EN.
Treatment technologies
The main attention is paid to the basic treatment processes of both surface and groundwater. In this context, for example, the optimization of coagulation test conditions is solved in order to obtain both high-quality treated water and a well-separable suspension. In the case of groundwater, it is primarily a solution of the calcium-carbonate balance, which is the dominant balance in the de-acidification, de-ironing, and de-manganization of these waters.
Ion exchange, sorption, and membrane processes
These methods are used for selective and non-selective removal of ions/solutes from water. Particularly attractive is the selective removal of heavy metals from water using ion exchange technologies, the removal of arsenic using inorganic sorbents, or the removal of trace concentrations of organic substances (see below). Membrane technologies can be used not only for the treatment of drinking water but also for the treatment of some types of wastewater.
Modern oxidation processes
The so-called Advanced Oxidation Processes (AOPs) have demonstrated considerable potential in removing difficult-to-biodegrade pollutants from wastewater. Their common denominator is the course at normal temperatures and pressures, and especially the use of extraordinary reactivity of hydroxyl radicals. At present, we are mainly dealing with processes based on the use of ozone and hydrogen peroxide. The main research topics include the possibilities of using AOPs for the removal of nitrogen compounds, with emphasis on the possibility of oxidation of ammoniacal nitrogen to gaseous nitrogen or increasing the biological cleanability of industrial wastewater.
Micropollutants
The issue of water treatment has recently shifted to the field of micro-pollution of water resources, especially metabolites of pesticides, or drug residues, and ATB resistance genes. We deal with the influence of advanced oxidation processes and sorption on various types of materials to remove these substances. By using sorption or precipitation processes, we also solve the removal of heavy metals, we also pay attention to the issue of microplastics.
Biological stability of drinking water
In real distribution systems, we can often notice the presence of residual organic substances after treatment processes designed to reduce the content of organic carbon in water, which is the reason for increasing the production of organic matter, biofilm, which covers the inner walls of pipes or parts of technology. One of the chemical-biochemical methods that evaluate or, as a result, predict the deterioration of drinking water quality is the determination of the BDOC (biodegradable dissolved organic carbon) indicator. The work of the working group is also focused on this method of evaluating the biological stability of water.
Recycling and reuse of treated wastewater
The Group participates in solving the topic of recycling and reuse of treated (urban) wastewater, where it is possible to replace the drinking water used so far with this water. This is mainly water for irrigation in agriculture, lawns of sports facilities (golf, football), urban greenery, or utility water to maintain the cleanliness of cities and towns. The economic intention is to produce service water that is cheaper than drinking water used for these purposes, while at the same time using water resources sparingly. The project of recycling and reuse of treated wastewater combines two relatively different topics of water technology: water treatment and wastewater treatment.
Monitoring the quality of watercourses and rainwater
We have been monitoring the quality of the upper reaches of the Krkonoše rivers for a long time, especially the Elbe, Úpa, Jizera, and Jizerka. At the same time, the quality of rainwater in the area of Luční hora - Strážné is also evaluated. Sampling is performed directly in the flow of the mentioned rivers and flows are measured using a magnetic induction flow meter in order to evaluate the mass balances of the monitored indicators.

third generations sequencers have been bought to our lab and will be used independently in the project of doctor Marie ....(project, grant etc.) and prof, Bartacek ...
The technology has been used since 2015, but lately, the improvements in chemistry and data processing significantly decreased error rates it was generating. So in 2019 MinION is ready to help us investigate the WWTPs.
To learn more about this fascinating technology and device visit Oxford Nanopore Technologies webpage
