A/O-MBR was conducted to treat simulated sewage and domestic sewage in this paper, and degradation of pollutants in reactor was studied at the same time. The results showed that the process had excellent removal efficiency of pollutants, under the conditions of C/N was 8:1~10:1, MLSS was 5~9g/L, HRT of part A was 3.93h, HRT of part O was 5.5h, DO of part A was 0~0.5mg/L, DO of part O was 1~3mg/L....
Sewage discharge creates a serious environmental pollution in water resources. This is the one of the biggest pollution problem in India. The rapid growths of the population, the technological and industrial boom have brought enormous problems and degradation of the environment. Effective collection and treatment of municipal wastewater is a critical problem in a fast developing country like India...
This paper is concerned with the alternative proposed here in order to treat domestic sewage from residential district for reuse in a combined system composed of an anaerobic filter (AF) - aerobic contact reactor following by sand filter. The AF reactor, investigated in present study, represented an efficient pre-treatment process for domestic sewage at -4-25degC. Average COD removal efficiency accounted...
