Abstract
The article discusses the use of concentrated coagulant aluminum sulfate solution to increase the efficiency of upflow clarifiers for drinking water preparation. The water treatment using coagulants from roughly dispersed and colloidal contaminants is one of the most common methods. However, the reagent consumption is quite significant under adverse coagulation conditions (insufficient alkalinity, high chromaticity, and low water temperature), therefore this method requires improvement. It was established that the considered method for the increasing efficiency of upflow clarifiers of water supply systems at drinking water preparation by using the concentrated solution of aluminum sulfate coagulant can reduce the reagent consumption by an average of 15-20%, to improve the water treatment quality and to increase the treatment setups productivity. Therefore, the actual tasks are to study the features of the coagulation process and the influence of various factors for the natural water treatment quality and the scientific improvement and technological regime choice elaboration for water treatment in upflow clarifiers with the concentrated coagulant solution using.
