Reconstruction of high colored and low turbidity water treatment facilities
Summary
By the example of Severodvinsk municipal water treatment facilities the specific features of the upgrade and partial retechnologisation of the high colored and low turbidity water treatment process are considered. The measures were aiming at meeting the regulatory requirements and minimizing the water treatment cost. Such processing technologies as sludge recycling in combination with the use of flocculant, upgrading the mixing and flocculation chambers with the use of mechanical mixers, automation of dosing equipment with continuous instrument control provide for the sustainable and efficient operation of the water treatment facilities. The implemented water treatment technology including the use of coagulant and organic flocculant as well as coagulation in contact with sludge separated from the settling tanks and subsequent filtration in sand-dolomitic bed filters allows producing drinking water that meets the current standards.
