Elastic Membrane-based Membrane Bioreactor (MBR) with High-Efficiency for Fouling Control

Novel class of flat sheet membranes for use in the Membrane Bioreactor System, to improve the fouling removal efficiency. Background: Membrane bio-reactors are designed to remove contaminants from waste water. This waste water can come from residences, businesses, industries, and runoff water from rainfall and/or flooding. A membrane bio-reactor (MBR) employs micro-filters (membranes).For currently available membranes, only the loosely attached foulants can be removed during the backwash process. By contrast, those particles, colloids and solutes that are comparable or smaller than the pore sizes can easily get stuck in the pores and cannot be removed by simple physical cleaning. In this case, harsh chemical treatment is often used to cleanse the fouling. However, repeated uses of chemical cleaning can accelerate membrane deterioration and shorten the membrane lifetime. Technology Overview: Dr. Bemjamin Chu, Distinguished Professor at Stony Brook University invented a novel class of flat sheet membranes composed of elastic micro filtration membranes and a non-woven elastic substrate. This invention can be used in a Membrane Bio-reactor system to improve the fouling removal efficiency. Preventing the accumulation of "irremovable" foulants by using this invention, will decrease the amount of chemical cleaning demanded for Membrane Bio-reactor Systems, increasing the service life of the membrane and reducing the disposal of toxic and caustic spent chemicals used in the cleaning process. Advantages: Significantly higher efficiency than currently commercialized membranes while maintaining high flux the pore sizes are adjustable depending on the applied trans-membrane pressure (TMP) Applications: Preventing the buildup of fouling in Membrane Bio-reactor Systems without using harsh chemicals Intellectual Property Summary: PCT Filed Stage of Development: Licensing Potential: We seek to develop and commercialize, by an exclusive or non-exclusive license agreement and/or sponsored research, with a company active in the area.
