In the framework of the given article shall be considered a negative impact on microorganisms of ions of zinc, copper and Nickel concentrations in the incoming wastewater to the wastewater treatment facilities of the cities of the Lower Volga region is unacceptably high, which inevitably reduces the quality of the purified water at the indicated metals exceeding the output after biological treatment is more than 30 times). Further, in the proposed article, we describe the results of studies aimed at disposal and treatment of waste activated sludge. The first attempt to use the resulting after biological purification of waste as a secondary raw material for the adsorption material, which retrieves the designated heavy metal ions from wastewaters prior to biological treatment, which allows further the activated sludge fully interact with other ions without losing their functions. As a result, after the biological cycle treated water at the indicated metals, meets the relevant standards.

Considered clean water in swimming pools, on nonionic and anionic surfactants with special adsorbents. Water purification pools plavatelnyx unique, first of all, because the water contains various types of pollution, which it is exposed. Most of these contaminants are introduced by the users of the swimming pool and they have to be removed or destroyed (bacteria, viruses, organic, sweat, hair, makeup, etc.). Treatment of swimming pool water is much more complicated because of the need to carry out her many times, than drinking water treatment, which is carried out one-time. Based on these studies, given technological solution to improve the efficiency of purification of circulating water in swimming pools, ensuring high environmental and economic performance of water treatment.
