Title:
A REVERSE OSMOSIS SYSTEM HAVING AN ADJUSTABLE FLOW RESTRICTOR FOR IN-SITU ADJUSTMENT OF CONCENTRATE WATER TO A DRAIN, AND METHOD OF PERFORMING THE SAME
Document Type and Number:
WIPO Patent Application WO/2023/116192
Kind Code:
A1
Abstract:
An RO system capable of adjusting concentrate water flow based on in-situ monitoring of the feed water TDS concentration level. An adjustable flow restrictor is located into the drain line of a reverse osmosis system, which is designed to alter the flow rate of the drain water as a function of the TDS concentration level of the source water or the TDS concentration level proximate a reverse osmosis filter egress port. A self-regulating drain valve is responsive to the instructions from a transmitted signal corresponding to the TDS concentration level measured by a TDS sensor. The self-regulating drain valve activates a motor, which rotates a spool. The spool has one aperture of varying width or a plurality of different sized apertures.
