Abstract
Wastewater can be treated using a combination of a settleable solids separator, such as a vortex separator and a membrane separation system. Removal and segregation of materials that adversely affect operation of the membrane separator earlier in the treatment process can improve water throughput, water quality and the lifespan of system components. Physical separation of settleable solids and floatable materials from the wastewater prior to treatment with a membrane separator can allow higher flow rates to be achieved.
