WesTech Engineering, Inc.

- MBR - Membrane Bioreactor


The WesTech ClearLogic® Membrane Bioreactor (MBR) featuring the new Alfa Laval Hollow Sheet™ Membrane Technology offers clear advantages to the MBR process. Advantages of the ClearLogic MBR include ultra-low transmembrane pressure, even flux distribution across the membrane and full chemical circulation during clean-in-place (CIP) operation.

During CIP, the membrane not only receives even chemical distribution, but also can be back-flushed. The results of these benefits include simple operation, fewer components, decreased maintenance, fewer cleaning cycles and longer life.

WesTech brings extensive biological wastewater treatment experience and offers a complete MBR system from turnkey plants to existing plant retrofits.
