Special aspects of coagulation and floculation processes in wastewater treatment

Nowadays the high development of the industry leads to the inevitable pollution of the environment all over the world. First of all, it has a negative effect on the hydrosphere because, anyway, waste water falls into a reservoir or go into the ground water through the soil. The paper explores the issue of optimizing the removal of protein and lipid impurities from wastewater under exposure to the compositions of coagulants and flocculants; in this case anionic acrylamide/sodium acrylate copolymers were analyzed. It was established that by adding compositions of coagulants with flocculants to wastewater it is possible to significantly reduce the content of protein and lipid impurities. The authors determined the efficiency of the coagulant-flocculant compositions, which depend on the conditions of reagent introduction, special qualities of wastewater, nature of the coagulant, concentration, molecular weight and charge.
