ENHANCED MEMBRANE BIOREACTOR PROCESS FOR TREATMENT OF WASTEWATER

摘要

Embodiments provide an apparatus and method for a membrane bioreactor process including a media in the water circulation module. Along with air supplied from bottom of the module the media components are kept in dynamic condition between the gaps to scrub the membrane surface area to it clean in-situ. Continued cleaning of the membrane surface results in benefits of reduced/no physical and chemical cleaning requirement, high flux, low TMP, and reduced frequency of chemical cleaning. The use of highly porous polymeric media having large internal surface area provides the advantage of retention of microbiological culture for a longer time without any disturbance causing an upset condition while increasing the biological loading and treatment capacity of the reactor.
