System and method for separating oil and particles from produced water or fracturing water

This invention relates to a system and a method of separating oil and water from produced or fracturing water comprising at least the steps of feeding through produced or fracturing water to a mechanical separation system comprising a solid-fluid separator with a mem-brane system configured to process the produced or fracturing water in an intended separation direction; and which membrane system is configured with a back flush system. The method comprises a step of separating oil to an oil conduit and water to a water conduit. The method comprises a step of back flushing the membrane system with a back flushing fluid using water from the water conduit. For continuous operation the step of back flushing is performed periodically.
