Abstract

A submerged rotating membrane bioreactor (SRMBR), with a rotatable, rounded, flat-sheet Poly(vinyldiene fluoride) (PVDF) membrane module fixed on the hollow axes and moved by an electromotor, was used for wastewater reclamation. The efficiencies of SRMBR, the effects of operation parameters on membrane permeate flux were studied. It was found that the effluent COD became stable and lower than 20 mg/L after one day running when the influent COD varied in the range of 180 mg/L to 368 mg/L. The equilibrium permeate flux increased from 42.5 to 47.5 L/m2Ã—h with the rotation speed increasing from 15 r/min to 25 r/min. Prolonging suspended time could alleviate membrane fouling and enhance the permeate flux.
