Application of membrane processes for distillery wastewater purification-a review

Worldwide environment regulatory authorities are becoming more and more stringent in setting norms for discharge of wastewaters from industries. Distillery wastewaters are highly polluted and their pollution potential is one of the most critical environmental issues of today. For these reasons, distillery industries are forced to look for more effective technologies for wastewater treatment. In recent years, membrane processes have been widely used for various applications, especially for wastewater treatment. The usage of membrane technologies is reflected in high removal efficiency, optimal costs and simple handling with devices. This review presents these membrane processes in the sense of their application on distillery wastewater purification.
