Industrial Brackish Water Reverse Osmosis Unit 144,000 GPD - USA

Product Description

Pre-treatment of raw water includes antiscalant dosing to minimize the precipitation of sparingly soluble sulfate salts, sodium bisulfite (SBS) dosing to remove free chlorine in the feed water.

The Brackish Water Reverse Osmosis system was selected from our RO-400 Series. BWRO unit consists of 5-micron cartridge filters to reduce feed water Silt Density Index (SDI) and to limit the SS to 5-micron size.


From a feed TDS of about 1,000 mg/L at a temperature range of 19°C and 27°C, the BWRO skid produces 100gpm of drinking water with TDS less than 50mg/L.


Estuaries and river openings are places where brackish water can be found. This type of water lies in between fresh water and seawater. It’s not as clean as fresh water, yet not so highly concentrated in salt as seawater. Even if it has a mild salt concentration, it is still not encouraged for consumption.



In July 2008, Pure Aqua successfully supplied Industrial Brackish Water Reverse Osmosis (BWRO) system to produce 144,000 GPD of product at 77°F using (20) 8"x40" Hydranautics ESPA1 membrane elements, (4) 5M FRP pressure vessels, SS multistage Grundfos CRN pump, microprocessor based controls and a digital conductivity and ORP read out, 460V/3ph/60Hz.

  • Small footprint
  • Plug and play installation
  • High-quality components (Grundfos pumps, DOW Filmtec membranes, Codeline vessels, Pure Aqua microprocessor control panel)
  • High recovery design
  • High rejection membranes
  • Low energy and chemical consumption

    We used this system as an industrial bwro unit in USA. This is a great system when it comes to the filter operating to its full capacity.
