[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.

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.

[obsah] => Hydrochemistry
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.
