METHOD FOR CLARIFYING TURBID WATER BY TREATMENT THEREOF WITH FLOCCULANT IN SUPPLYING PIPELINE

摘要

FIELD: water purification. SUBSTANCE: invention concerns methods of clarifying water from surface sources and can be utilized in the field of household- drinking and technical water-supply engineering. Flocculant is entered into pipeline or into water before its directing into pipeline which is used for mixing flocculant with water and aggregation of suspended particles. Distance from point of entering flocculant to settlers constitutes 500-60000 m, stream velocity gradient in pipeline 68-346 s, and treatment time 0.13-44 h. When on pipeline. pumps for additionally raising water are available, flocculant is entered before one of them. EFFECT: optimized suspended material aggregation and improved settling of turbid water in settlers. 2 cl, 2 tbl, 2 ex
