摘要：The article reveals various factors, which determine the maintenance of membrane bioreactors for treatment of domestic and industrial sewage. Contamination of membranes is a consequence of poor pretreatment, when membrane accumulates hair, scraps of rags and other fibrous materials on its' fibers and in the cavities of membrane blocks. Aeration conditions have a significant impact on the performance of the membranes, also in sufficient sludge liquor mixing leads to membrane clogging. Size of pores, material of membrane and washing peculiarities are the factors that can affect MBR operation. The costs for installation and operation of membrane modules is still the limiting factor of their wide application, however now the situation is changing. There are key differences between membrane and conventional treatment of wastewater revealed such as costs, required area and quality of treatment.
