Abstract

Abstract

Membrane bioreactor has become one of the important water reclamation equipment. It is advantageous in enhanced biochemical treatment performance, steady effluent quality and quantity, etc., but is impeded for further application by high investment and operational costs. This study developed a novel arrayed flat sheet membrane for membrane bioreactor, which had a critical flux at 114~120 L/(m²·h) with better uniformity than the hollow fiber membrane. The application in municipal wastewater treatment plants revealed that the novel arrayed flat sheet membrane had significantly lower and slower-growing transmembrane pressure than the hollow fiber membrane with flux at 16~25 L/(m²·h) and regular high-intensity aeration. The effluent quality met the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002,I-A). Thus, the novel arrayed flat sheet membrane could guarantee the effluent quality and reduce the operational cost of membrane bioreactor.
