Abstract:

The results of laboratory studies on selection of reagents and optimal dose during treatment of low-mast water of Saratov reservoir with high permanganate oxidability are presented. Laboratory studies of purification of low-yield water with high permanganate oxidability by POHA coagulants «Aqua-Aurat 30», aluminum sulfate and flocculants Praestol 650, PAA and Magnofloc LT-20 are presented, which can provide maximum degree of water clarification, with minimum content of residual aluminum in drinking water and permanganate oxidability value. The obtained results of experimental studies on the coagulation of low-flow waters of the Saratov reservoir with high permanganate oxidation in the flood period showed that the maximum decrease in permanganate oxidation concentration is achieved by settling at an optimal dose of coagulant «Aqua-Aurat 30» – 8.0 mg/dm³ by Al₂O₃ and a dose of flocculant Praestol 650 – 0.3 mg/dm³. The value of residual aluminium in purified water is 0.03 mg/dm³.
