| 20080272057 | RECYCLING OF WASTE WATER - An upstream conduit extends from a container containing reusable waste water to a junction and a downstream conduit extends from the junction to a destination for the waste water. There is a third conduit through which fresh water, under pressure, flows to the junction.

Part of the feedstream fluid flows in one of: a forward flow direction where it passes in a first direction through a wall of the filter element; and a reverse flow direction where it passes in a second, opposite direction through the wall. The filtrate is directed into a flowline for collection. The feedstream fluid is then arranged to flow through the filter element in the other direction, to remove contaminant material from a surface of the element wall. Following removal of contaminant material, the feedstream fluid is continued to be directed through the wall of the filter element in said other direction, to filter out contaminants from the fluid during flow in said other direction. | 05-14-2015 |
