| Title of the article | Some aspects of wastewater treatment, formed during the washing of fast filters |
| Abstract. | Problem statement. In the preparation of natural and waste water, rapid pressure filters with granular loading are often used. When washing fast filters with granular loading, sewage is formed which amounts to 10-20 % of the capacity of the filter station. The concentration of suspended solids in washings varies greatly and reaches 1,200-1,500 mg/l according to literature sources. This article is devoted to the purification of washings from suspended solids. The purpose of the research is to reveal the qualitative characteristics of the washing effluents of the fast pressure filters with granular loading, and also to develop a technology for their purification. Results. The main results of the study consist in determining the qualitative indices in the washing effluents of the fast filters, depending on the content of suspended solids in the initial and purified water under various technological washing regimes. Conclusions. The significance of the results obtained for the housing and communal services is to determine the qualitative indicators of the washing effluents of the fast pressure filters and also to develop a technology for their purification that will allow the use of washings in the systems for the preparation of natural waters, as well as to reduce the discharge of contaminated washing effluents of the fast filters in surface sources or drainage system of settlements. |
