MemPulse™ Membrane Bioreactor Systems

The B50N membrane module is the latest in the ‘N’ series of MemPulse™ membrane modules. The membrane fibers are bound together into B50 modules using a unique dual-potting system and set within a compact modular rack that is placed in a separate membrane tank. Mixed liquor is fed into the membrane tank and the membranes are air scoured using MemPulse™ aeration. The filtrate pump then draws the water through the fiber wall, thus filtering the water from the solids and the filtrate is pumped away for use elsewhere. The MemPulse™ Membrane Bioreactor (MBR) System uses a unique pulsed, plug flow aeration to greatly increase process efficiency and reduce energy usage. A continuous air flow is evenly distributed to each aeration device where it is accumulated and then released as a pulse of large bubbles that increase in size as they move up the membrane fibers. The size and random nature of the large bubbles or slugs of air prevent trash and solids build up by pushing debris away from the membrane fibers at the surface. DuPont's membrane system is industry-leading in energy consumption with specific energy usage as low as 0.07 kWh/m³ and delivers superior filtration performance while reducing aeration energy by up to 65%.
