Description

Overview

BWB reverse osmosis systems are used for treating most bore water types, for treatment of feedwaters with TDS values up to 10,000ppm, or where a permeate flush feature is required.

RO pressure vessels are FRP high pressure types with high performance membranes and the open frame is electro-polished 304 grade stainless-steel.

Metal wetted surfaces are 316 grade stainless steel or corrosion resistant brass.

A permeate flush facility is standard and operates each time the system is started and every 3 hours thereafter to assist with keeping the membranes clean.

An optional booster pump is available for integration into the system should a pressurised feed from the RO permeate storage tank not be available.

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