Optimization of Coagulation Water Treatment

Summary

Results of experimental studies on the electrocoagulation treatment of the Don water for organization of the centralized systems of water supply are presented. The electrocoagulation method of natural water treatment in contrast to the reagent method is more ecological and economically efficient. The studies carried out confirm the reasonability of a wider use of electrocoagulation for tap water treatment.

Efficiency of Natural Water Disinfection in the Course of Coagulation Treatment

Summary

Results of experimental and theoretical studies of the coagulation treatment of the Don water and monitoring of the concomitant process of its disinfection are presented. The mechanism of separation of algae, bacteria and viruses from water due to their sorption on aluminium hydroxide generated in the course of coagulation is described. The best effect of water disinfection observed during electrocoagulation is 93,8%. The use of this method makes it possible to abandon the primary water disinfection with chlorine, exclude a large-size reagent services and improve the ecological situation in connection with reduction of the volume of the generated sludge (waste of coagulation process).
