The results of the study of the combined effects of UV germicidal irradiation and ions of silver (or copper) to the water disinfection process, including and at high temperatures and the pasteurization process. Simultaneous exposure to UV rays and ions of silver (or copper) to the E. coli bacteria in the water can significantly increase the depth of the final disinfection, reducing the dose of UV radiation results in energy savings and is promising for service water supply systems. It was also found that the combined effect of UV-irradiation and silver ions (or copper) achieves at a temperature of 60 ° at the same level of disinfection, as the high temperature pasteurization. An additional advantage of joint use of UV radiation and ionization is to increase the resistance of the secondary bactericidal water pollution.
Vruce E.Rittmann, Douglas Stilwell Modeling of biological processes in drinking water treatment: the integrated model biofiltration
Biofiltration refers to biofilm processes, giving biological stability of drinking water, resulting in the distribution of water in it is supported by an overgrowth of bacteria. Biofiltration eliminates many water quality problems associated with the biological instability: high doses of chlorine disinfection by-products, accelerated corrosion, taste and odor, turbidity, coliform and heterotrophic growth. Most designs of biofilters are empirical. However, using a mechanical model as a tool in the design, it is possible to increase the reliability and effectiveness of the pilot and laboratory biofilters. Unfortunately, the models that include all the necessary conditions are complex, and they are good for research purposes, but are not suitable for routine design and analysis. Integrated model of biofilm (MPI) is a computer program biofiltration drinking water. It takes into account all of the key phenomena, but easy to use. In particular, the model takes into account the consumption and the formation of chemical substances (incoming substrates, end products, soluble microbial products), heterotrophic and nitrifying bacteria, inert biomass, physical processes, such as transport and separation, as well as the relationships between different organisms and chemicals. The example shows entering information into the model and identify its character changes in the source substrate, soluble microbial products and Biofilm biomass IMB produces direct iterative calculation and analysis of biofiltration.

L. I. Kantor, E. V. SHemagonova, E. A. Kantor Some sources of benzo (a) pyrene, influencing its contents in a water body (for example, p. Ufa)
Polycyclic aromatic hydrocarbons (PAHs) are a high priority environmental pollutants and are found everywhere in the air, soil, water supply sources as a result of global emissions. Indicator of the presence of PAHs in the environment is their most carcinogenic and mutagenic representative - benzo (a) pyrene. Intake of benzo (a) pyrene in the environment is mainly due to incomplete combustion of fuels from stationary and mobile sources. The results identify sources that define the content of benzo (a) pyrene, in alignments of three intakes p. Ufa, two of which are located to the industrial area of the city on the river, and one - downstream of the industrial enterprises node. The analysis shows that all cross-sections p. Ufa have mediated ("atmospheric") and direct contamination, as an important source of influence on the content of benzo (a) pyrene in water, are CHP plants using fuel oil, and river transport.
