Prediction model of transmembrane pressure jump for membrane bioreactor using physical and statistical approaches

摘要

In water treatment fields such as sewage treatment and industrial liquid waste treatment, the membrane bioreactor (MBR) has been widely used to purify wastewater for reuse. MBRs combine biological treatment with membrane filtration. First, bacteria within activated sludge metabolize the organic pollutants and produce environmentally-acceptable metabolites, and then, a microfiltration or ultrafiltration membrane separates liquids from solids, i.e. the clean water from the sludge.
