Popis: A flux recovery model of chemical cleaning of microfiltration membranes in membrane bioreactor (MBR) was proposed based on Hom–Haas model. This model provides intuitive prediction of flux recovery as a function of cleaning time and cleaning solution concentration for PAN microfiltration membrane fouled with activated sludge from membrane bioreactor (MBR). The quantitative effects of different chemical cleaning conditions (temperature, transmembrane pressure and agitation speed) on model parameters were calculated by means of Multiple Linear Regression. High accuracy of the proposed model is approved not only by chemical cleaning agent of NaOCl, but also by other cleaning agents such as NaOH and SDS.
