Design of Low Energy Integrated Membranes Units for Production of Highly Purified Water

Abstract

Some industries like medical, pharmaceuticals, cosmetics, chemical manufacturing need a special quality of treated water which is called Purified water. Integrated membrane system was designed and developed to produce Purified water grades to serve these industries. A simple engineering design for water filtration through membrane systems was scanned; beginning from carbon filters, followed by different kinds of membranes like microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane. These units were developed according to membranes type and the produced water quality before and after each unit. The Produced water and its quality control tests were compared with the World Health Organization water quality standard. The produced water from the integrated membrane system has TDS reached 0.95 mg/L, which matched with the World Health Organization water quality standard.
