Optimal Saving Membrane Operation (OSMO) (TPC.6115)

Membrane separation is a modern process to purify liquids at minimal investment and operating costs. Currently, many classical water production processes are transferred into membrane processes. However, feed water impurities rejected by the membrane cause internal membrane fouling and external cake forming build-up. Such fouling deposits have to be removed cyclically by backflushing and chemical cleaning treatment. As a result of the fouling deposit, cyclic mechanical forces and chemical cleaning procedures, the membrane is subject to aging.
The Dutch membrane OSMO focuses on the production of drinking and process water with polymer membranes modules which are applied in a so called dead-end operation. In fact, the development of this membrane operating mode must be considered as the breakthrough since it allowed reducing energy costs dramatically and making membrane water production economically attractive.
