Membranes separations technology for industrial effluent treatment - a review

This paper has attempted to identify some of the opportunities offered by membrane processes in effluent treatment applications, but there are no easy answers; no single technology is the solution for all problems. Certainly, the requirement for testing cannot be emphasized enough; however, for those applications which testing indicates can be effectively treated with membrane technologies, they can provide outstanding performance. Some experts predict that, within 10–20 years, effluent treatment, along with food and chemical processing, will represent 80–90% of the total membrane processing market. The time has come - opportunity awaits!
