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.

1. A method of treating wastewater containing settleable solids to form a reusable liquid fraction, comprising: separating a wastewater stream into a first component including utilizing centripetal forces created by differential flow velocities, the first component including an amount settleable solids greater than an amount of settleable solids in the second component means for creating centripetal separation forces within the vessel caused by differential flow velocities; applying the second component to a membrane permeable to selected ingredients of the second component; and concentrating the second component on a surface of the membrane to form a solids concentrate and a reusable liquid fraction.
