Title: Recovery of potable water by reverse osmosis using mains pressure
Inventor: SCHMIDT DIETER
IPC: B01D61/06
Filed: 1997-01-23
Abstract: A filtering method recovers drinking water from a main. It is taken at mains pressure for reverse-osmosis filtration. The flow is divided into and designated as, service- and potable water streams, the former being sent directly to consumers. The potable water stream is sent for reverse osmosis. Energy is extracted from the service water stream during its consumption by the user, this energy being used to raise the system pressure of the potable water stream, to that required for the reverse osmosis process. Also claimed is the corresponding equipment for potable water recovery. A hydropump provides the required pressure increase. This may be externally driven in addition. Some water sent for reverse osmosis (13) leaves as permeate, entering the reservoir (21). The remainder becomes a concentrate (of impurities) which is returned into the service water stream, being first passed through flow restriction. The permeate is cooled in the reservoir. The pump inlet for the water designated potable, has reverse flow protection. The reverse osmosis unit is cooled by the drinking water supplied. Permeate passes through filters (20).
