ABSTRACT
The viability of obtaining aluminium coagulant from the solid vinyl chloride production waste (spent catalyst) was studied. The new coagulant Al6(OH)13Cl5 was established to be effective for clarifying water with high levels of suspended substances. The consumption of the new coagulant is significantly lower than that of conventional aluminium sulphate. The application of the new coagulant, aluminium chlorohydrate, makes it possible to enhance the properties of the purified water, in particular, its hardness. The method for obtaining the new coagulant and its use for water conditioning and purification was proved viable. The process flow sheet diagram for the coagulant production was suggested
