The Pulsion MBR membrane bioreactor pulses a large bubble through a chambered fiber bundle, creating anefficient pumping action that results in lower air and aeration energy requirement
s than traditional air-scour methods, says the manufacturer. Improved recirculation within the membrane module boosts achievable fluxes. An increase in packing density allows the overall system footprint to be significantly reduced. A reduced air flowrate applied to the membranes on a continuous basis reduces the size of the air-delivery equipment by an estimated 50%. — Koch Membrane Systems, Wilmington, Mass.
