Thesis topic:

Effects of materials in direct contact with water on microbial growth

Motivation

Water is often in contact with various materials, be it during water treatment, its distribution or accumulation. Selection of materials utilized to manufacture the products intended for the contact with drinking water is regulated on the basis of technical requirements and criteria affecting water quality due to the release of substances and influencing of water odour and colour. The materials coming into contact with drinking water must conform to the directive No. 409/2005 Coll., on hygienic requirements for products being in direct contact with water or participating in water treatment. The materials commonly applied are not assessed from the perspective of their possible support of microbial growth and biofilm formation or a possibility of drinking water turning unstable when in contact with such materials. A problem of hygienic (microbiological) nature also occurs when specific materials support the growth of microorganisms. This applies to the materials containing organic substances that may be utilized by microorganisms hence causing organoleptic, physical and microbiological quality of water. Occurrence of biofilms in the distribution system affects organoleptic properties and safety of drinking water, i.e. its harmlessness and, last but not least, it also affects corrosion aggression from the operational perspective. 

Solution

  • To compare various materials in relation to different stages of water treatment
  • Possibly propose new materials which would inhibit the microbial growth while not affecting the quality of drinking water and being environmentally friendly
 
A new regulation that is in preparation deals with sophisticated methods that will be used to compare microbial activities. These are namely a method using ATP concentration measuring, a method measuring the biofilm formation and a method assessing microbial activities on the basis of dissolved oxygen. Also, a confocal microscope will be used as well as standard determination techniques used to analyse drinking water.
