Thanks for telling us about the problem. Published January 1st by Editorial Limusa S. Environmental impact on groundwater. The alternative use of calcium sulphate di-hydrate CaSO 4 ‘2H 2 O as a coagulant-flocculant in the primary treatment of wastewater may be economically and environmentally beneficial. It is important to emphasize that there are no antecedents for the use of calcium sulphate as a coagulant-flocculant. Jar test apparatus The sedimentation equipment jar test apparatus; Fig.
