“…Biofilm is a group of microorganisms that are linked by trophic dependence from autotrophic and heterotrophic bacteria and fungal toxins and their parallel developing consumers, such as flagellates, ciliates, and creepers [7][8][9][10][11][12]. Bio-stable water is considered to be non-microbial and does not sustain the growth of microorganisms in the water supply network.…”

The subject of the work is the analysis and assessment of the risk of biological instability of water. The lack of water stability causes the increased susceptibility of the distribution system to secondary microbial contamination of water and constitutes a hazard for consumers’ health. The risk is expressed as the loss of water supply safety and distinguishes a failure of not meeting certain water quality parameters that can influence physico-chemical parameters and the bacteriological quality of the water supplied to the consumers. In the paper the method of analysing and evaluating the risk of loss of biostability of tap water is presented. The presented analysis was performed on the basis of the operating data from the water treatment plant.

“…A significant use-related problem of water supply systems is widespread secondary water contamination when water is transported to the consumer [8][9][10][11]12]. The biofilm forming in the water pipes network is a considerable habitat of microorganisms, including pathogenic ones.…”

Ozone, due to its strong oxidizing properties, is often used in high efficiency water treatment processes. It is not only used for water disinfection, but also for carboxylic acid, a product of its reaction, which highly contributes towards increasing biodegradability of organic substances in water, thus leading to higher quality of drinking water. This paper presents results of using mobile ozone devices as a way of local microorganisms elimination and sediments removal from WSS.

Elements of Utility Theory and Analysis of Teaching Process

Abstract: The authors attempt to carry out an analysis of the teaching process from the position of the utility theory and the social choice theory. They also stress the role of the value theory in the analysis of this process. The role of e-learning is also emphasized in the article.
