Tech Brief: Improving The Outlet Water Quality Of An RO Membrane - Electrodeionization (EDI/CDI)* System Using Liqui-Cel Membrane ContactorsSource: Membrana
RO membranes coupled with EDI/CDI technology are rapidly gaining acceptance in the production of high purity water. Coupling the two technologies offers many advantages to the conventional RO mixed bed system design. The overall performance of a RO-EDI/CDI system can be improved by removing dissolved carbon dioxide between the RO and EDI/CDI units. Membrane contactors are commonly used in conjunction with these technologies to provide a low maintenance, chemical free, high purity water system.
