Colloid-Chemical Regularities of Reagent Wastewater Treatment of Dairies

A comparative characterization of chemical reagents Al2(SO4)3, FeSO4 and FeCl3 in the process of wastewater treatment of dairies. The colloid-chemical regularities of the course of hydrolysis of chemical reagents depending on the nature, concentration and acidity of wastewater are established. It was found that the greatest degree of purification from ether-soluble substances 87-88% is provided by the addition of FeCl3 at a concentration of 150-200 mg / l at a pH of 9.5-10.
