In recent years, MBR membranes have evolved to the point where they require less maintenance and at the same time have a longer useful life. An added benefit comes from the more advanced designs that consume significantly less energy and lower operating costs.

The new Puron™ module from Koch Membrane Systems Inc (KMS) is a second generation MBR membrane module that employs hollow fibers. Like several other second generation membranes, the high-strength fibers that comprise the Puron modules also overcome the fiber breakage problems typical of first generation systems that use non-braided fibers.

Second generation systems position the membrane bioreactor industry for even more rapid growth. They offer several advantages, including improved performance in terms of reduced fouling and lower energy consumption. They are also more robust than first generation systems and are usually designed with compatibility in mind to minimize retrofitting costs.
