Membrane Technology for Water Treatment in Korea

In recent years it has become necessary to design water management system to minimize water consumption as well as satisfy more stringent environmental requirements. This is mainly due to the seasonal water shortage and environmental problems on water pollution that have taken place at many industrialized regions in Korea. Accordingly, membrane technology in Korea is finding increasing application in the water industry because it has been found to be effective and economic treatment method compared with conventional technology. The membrane processes with the greatest potential for water and wastewater treatment are microfiltration(MF), ultrafiltration(UF), nanofiltration(NF) and reverse osmosis (RO), which utilize pressure differentials.
