Membrane Technologies in Wastewater Treatment: An overview

摘要

Membrane Technology (MT) includes all engineering approaches for the transport of substances between two fractions by using permeable membrane. In general, mechanical separation techniques for separating gaseous and liquid streams use membrane technology. Membrane separation techniques operate without heating and use low energy than conventional thermal separation technique such as distillation, sublimation and crystallization. The separation technique is purely physical and both fractions permeate and retentate can be used. Membrane Technology (MT) is widely used in food technology, biotechnology and the pharmaceutical industry. Furthermore, by using membranes enables separations that would be impossible with thermal separation methods.
