Experience to date foreign and domestic experience shows that the waste water can be used after proper treatment for a variety of purposes. One way of solving water management is the integrated use of enterprise disinfection municipal wastewater for technical water supply. However, as practice shows, the work of urban sewage treatment plants is not high. Often indicators reset water does not meet the standards. On the use of such water for technical needs cannot speak. Analysis of wastewater treatment plant in Kaluga has shown that in addition to traditional mechanical structures, biological treatment (sometimes using the chemical method) should be facilities physicochemical wastewater treatment as a last step before disinfection. Application is physico-chemical methods can not only stably produce the desired effect, but also the use of treated wastewater more efficiently - to the extent needed to re- using it for specific needs, such as manufacturing. Our study indicated that it is possible using a combination of traditional and new technologies in the field of wastewater treatment to obtain the desired results reset. This opens prospects for rational water use, as by adjusting the parameters of the flow requirements to reuse, reduces the volume of discharges into water, fresh water intake, thus decreasing the negative impact on the environment. These data suggest the feasibility of implementing such solutions for wastewater treatment and water treatment for the needs of industry on sewage treatment plants in Kaluga.
