Description

Overview

RD reverse osmosis systems are used to treat low TDS feedwaters encountered in municipal supplies, dams and river waters. Installation and operation are straightforward and there is little maintenance involved.

A membrane flush facility operates each time the system is started to assist with keeping the membranes clean.

Continual monitoring of feedwater pressure, RO permeate quality and storage tank level is performed by the controller.
