Opis:: This article presents the results of experimental studies pertaining to the suckling improvement of secondary clarifier in an aeration station in Almaty. According to the obtained research results, the work of secondary clarifiers was evaluated for the removal of suspended solids, concentration of returned sludge and sediment moisture. The technical specifications of aerations, secondary settling tanks and cesspool emptier in the aeration station of Almaty were defined. Additionally, it was shown that the use of the articulated sucker with movable scrapers can increase the efficiency of cleaning the bottom of the circular tanks. In this practical test, the proposed suckling radial settler in aeration station of Almaty during the year showed that the sucker reduces the costs for the installation and maintenance of cesspool emptier and has no damaging effects on the bottom of the sump.

Opis:: The household and industrial wastes that have been accumulated during the last 40–50 years organized and spontaneous landfills (garbage dumps) pollution of the natural water bodies near locations. As results of precipitation and solar irradiation, the drainage of water formation occurs; such waters are polluted with harmful and toxic ingredients. The known indices of pollution of industrial and surface waters as well as the technique for determining the class of danger posed by solid household wastes were analyzed. The application of this technique to liquid wastes is suggested, since the change of aggregate state must not restrict its application; on the contrary, a new useful unexpected result can emerge with this. A rather simple dimensionless index of toxicity was chosen on the basis of the following examples: composition of the drainage waters of a specific landfill, content of harmful ingredients in them, excess ratio of their maximum permissible concentration. Such an index takes into account the maximum permissible concentration of the harmful substance in the ground, as well as the fraction of the harmful ingredients in the total mass of the liquid waste. Using the dimensionless index of toxicity, the bar charts were drawn, from which the sequence of removal of harmful components from the liquid mixture can be determined, starting with the component with the least value of dimensionless index of toxicity which characterizes the most dangerous component.

Opis:: This article presents the results of studies on the comprehensive assessment pertaining to the peculiarities of nutrition, accumulation, transit and discharge of groundwater in the adjacent territory of the Sorbulak reservoir. The information about the waste water storage was presented. The results of the analysis and decryption of satellite images, as well as the results of aerial photography of the territory of the Sorbulak were presented. The results of field route studies of the work area were presented to identify the external manifestations of directional filtration, areas of exits to the daytime surface of groundwater. The results of the calculation of the filtration flow controlled by the Sorbulak storage lake, unloading through the western side of the plateau into the Kurty River, were presented.
