Abstract

Dissolution of nepheline-containing raw materials was studied in relation to the concentrations of dry formulation and aqueous acid solutions. The conditions in which a low-concentration composite coagulant‒flocculant can be obtained on the basis of a nepheline concentrate were determined. These conditions make it possible to synthesize the composite reagent in conventional reagent facilities of wastewater-treatment stations and, simultaneously, to take technological measures for improving the quality of purified water, with the secondary contamination of water by compounds of aluminum minimized.
