SYSTEMS & PROCESS
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.
PERFORMANCE
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.

Greatbwro system. First-rate!
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.
