Title:
REVERSE OSMOSIS SYSTEM WITH CONTROLLED RECIRCULATION
Document Type and Number:
WIPO Patent Application WO2002055182
Kind Code:
A9
Abstract:
A water treatment system (10) where concentrate water from a reverse osmosis element (15) or other tangential type filter is circulated and mixed with fresh feed water in an amount that permeates a filter membrane (16). The concentration of contaminants in the circulating stream is continuously monitored and when a predetermined level is reach, the system (10) is purged of the contaminated water and a new cycle is started. This results in a water purification system (10) that will self adapt to various water conditions, at differing sites or at an installed site, to provide the most efficient use of the feed water and energy for the amount of contaminants present in the feed water at any given time.
