Performance of membrane bioreactor under shock load conditions

Abstract

Increasing demands of clean water coupled with problems of water newlinescarcity and environmental pollution makes water reuse essential Membrane newlineBioreactor MBR is a promising technological option to meet such demands newlineThough MBR provides effluent quality of reusable standard its versatility to newlineshock loads remains unexplored An attempt has been made in the present newlinestudy to investigate the robustness of MBR under different shock load newlineconditions like hydraulic organic combined organic nutrient organic toxic newlinephenol and inorganic toxic sodium chloride shock loads newlineA bench scale aerobic submerged MBR 6 L working volume with newlinepolyethylene hollow fiber membrane module pore size 04 m was installed newlineand operated at three different HRTs 8 6 and 4 h newline newline
