Ion-Exchange Waterleau - Submerged Membrane Bioreactor - Brochure

Membrane Bioreactors For Compact Waste Water Treatment & Recycle. Ion Exchange Waterleau Ltd. offers two different membrane bioreactor concepts to produce an effluent that is extremely pure and appropriate for immediate reuse. Micro and ultra filtration membranes can be used for the separation of sludge and biologically purified waste water. By replacing the sedimentation step by membrane separation it is possible to operate the bioreactor at much higher concentrations, thereby reducing the volume of the bioreactor drastically.  An extra advantage of the fact that the filtrate is virtually free from suspended solids and bacteria since these cannot pass the membranes.  The filtrate will thus be ready for reuse or for further treatment by reverse osmosis.  Two membrane bioreactor concepts are possible depending on the choice either to submerge the membranes into the bioreactor or place these membranes in an external loop.
