Treatment of Wash Water of Filters and Water Disinfection at Water Treatment Complexes of the Azerbaijan Republic

Summary

Results of studies carried out for determination of efficiency of clarification and investigation of influence of quantity and quality of the wash water supplied to a head of treatment facilities on the subsequent process of treatment are presented. For full disinfection of water it is proposed to use a disinfectant received by electrolysis of a solution of salts of alkaline metals and mineralized ground water directly at the territory of water treatment station.

Utilization of Sludge of Water Supply Treatment Facilities

Summary

A possibility of the use of sludge of potable water supply treatment facilities for production of pottery is investigated. Technological tests show that the use of sludge of the Khabarovsk’s treatment facilities as additives to common clays in a dose up to 15% of raw material weight makes it possible to solve a problem of their utilization without a decrease in quality of a produced product. The possibility of the use of treatment facilities sludge in a dose from 3 to 15% as alloy additives making it possible to improve plasticity of ceramic mass, to improve conditions of its sintering, to reduce parameters of shrinkage at all technological stages of preparation of raw materials and manufacturing of products, to reduce the size of pores generated and to improve indices of water-absorbing ability is established.
