More Information
Summary:separation of solid and liquid phases of heterogeneous systems; treatment of sewage water; coal mining, carbochemical, mining, food-processing and chemical industries; manufacture of building materials. SUBSTANCE: method includes successive treatment of suspension with anion and cation flocculants followed by separation of solid phase from liquid phase. Used as flocculant is solution of polyacrylamide and/or its copolymers. EFFECT: increased productivity of separativity of separation of solid phase; reduced moisture content of sediment and content of solid phase in liquid phase. 9 cl
