METHOD OF ESTIMATION OF CONDITIONS FOR INTRODUCING FLOCCULANT Russian patent published in 2001 - IPC

FIELD: treatment of industrial and domestic sewage. SUBSTANCE: method includes determination of ash content of solid phase and loss of moisture in drying the residue to which flocculant is to be introduced. Type of required flocculant is determined on base of this determination. Then starting solution of flocculant is prepared. Different quantities of selected flocculant are added to samples taken the same settler. Samples with addition of flocculant are poured into molding reservoir and are compressed by means of piston, after which moisture content of solid phase sediment is determined. Then, dependence of moisture content of solid phase residue on parameters is determined and optimal combination of parameters is selected. EFFECT: reduced consumption of flocculant; improved quality of separated solid phase. 4 cl, 1 dwg, 2 tbl
