Presents the carrying scheme of water consumption and disposal of LLC Togliatt ikauchuk. Defi ned qualitative composition of the wastewater. Held survey of the biological treatment facilities with the collection of baseline data. The necessity of reconstruction of treatment facilities.

A mathematical model of choosing the most eff ective water purifi cation process chain, depending on the level of background contamination of water sources and the presence of anthropogenic pollutants on the basis of a classifi er system means PC «SupWater».

A question is examined about the possible methods of increase of efficiency of work of sewage treatment plants at the fence of water from a storage pool. 4 methods are inprocess considered: 1. Reconstruction of chamber of flocculation. 2. Replacing the primary chlorination during flowering pond water to ultraviolet disinfection with low water treatment with sodium hypochlorite. 3. Replacement of coagulant. 4. Adding to water of powdery absorbent carbon.

The paper shows the effective way of water supply and water drainage of small communities which consists in the reuse of purified sewage for irrigation purposes. A circulating water system has been developed which has some advantages due to a more simple technological scheme, lower drinking water consumption from the source and the use of biogenic elements of sewage water.

The sorption properties of natural sorbents (dolomite and shungite) in relation to the cations of manganese.The degree of extraction of metal cations of model solutions of the original and modified natural sorbents. Of the two studied sorbents more high degree of extraction of manganese ions removal from solutions is obtained for the natural sorbent - dolomite.

Conducted a study of the recycling process muriatic pickling solution containing cations of heavy metals. According to the results obtained when using oxidants in the process of allocation of the solid residue from the pickling solution increases the degree of extraction of cations of iron and zinc. Determinethecompositionofdrysediment.

An analyses of data of determine sediment degree in wastewater collector has been introduced in the article. Described the diffi culty of process and measurement tolerance of the sediment at present time. A new practical equipment for measuring sediments and fi lling of wastewater in the sewage networks has been provided and developed. Equipment’s measurement tolerance is 1-2 mm. The equipment is portable and easy to use in practice. Also it can be made and fi x in the sewage workshops.

Nowadays an actual problem is the environmental protection from pollution, in particular water sources. In this regard the great importance is got by sewage treatment. The object of research is sewage of fur association of «Melita». The existing scheme of cleaning of a production drain is considered.

We investigated the effectiveness of ceramic aerators on the basis of the Armenian tuff from the point of view of the mass-transfer characteristics as well as on the basis of laboratory analysis of the waste water samples in the aeration.

Composition and laws of reagent treatment of highconcentrated effl uent of turkey meat factory were researched. Experimental-industrial research was conducted to refi ne parameters obtained under laboratory conditions and modes of wastewater treatment that are the most eff ective in terms of their operating costs and quality of cleaning were tested.

The reasons of loss of water in apartment buildings due to excessive pressures (pressure) of water appliances. It is shown that the practical implementation of the regulatory requirements on the application of the apartment pressure regulators revealed its signifi cant systemic defect - worded compulsory hardware requirements are minimal, but not exhaustive, which eliminates the positive eff ect of its application. Defi nes the ways of improving the design of apartment pressure regulators and the mandatory requirements of the safety of buildings and structures.

The article presents information on the number of sewage treatment facilities in the Samara region, their technical condition. The causes of the necessity for renovation and modernization of existing facilities are considered. Information about the number of water users who has permissive documents for wastewater discharge; volumes of sewage of the enterprises taken away from sewer treatment facilities for 2012 is given.

The theoretical calculations, the raw data, graphs, calculation results and conclusions to reduce energy consumption by using integral control of the existing booster pump station versus unregulated work and that the stabilization of the output pressure of the pump station.
