System Analysis of Domestic Waste Water Treatment Facilities

Abstract

Parameters of treatment facilities by three groups were analyzed: small with capacity up to 5 K cu.m. a day, medium – up to 15 K cu.m. a day, and big – more than 15 K cu.m. a day. The analysis is aimed to determine technological steps, which determine the cost, area and required design electric capacity of the facility as a whole. The analysis revealed that for big facilities these are aerotanks and utility facilities; for medium facilities – aerotanks, sump tanks and utility facilities; for small facilities – primary settlers, aerotanks, utility facilities. The ways of technological steps improvement are formulated.
