Improvement of Treatment Technique of High Colour and Low Turbidity Water

Summary

Humic substances are governing natural pollutants of high color and middle color river water. NII VODGEO has conducted the studies of effects of non-organic and organic coagulants in combination with high molecular flocculants. In the course of studies the efficiency of water treatment with aluminium oxychloride and Polysept has been compared. To improve efficiency of treatment flocculants Praestol have been used. Molecular-mass distribution of humic acids in influent water and water treated with reagents has been investigated. Results of the experiments with natural water have been confirmed with the use of model solutions prepared on the basis of sodium humate and also humic substances extracted from soil, turf and river water.
