Industrial Brackish Water Reverse Osmosis Unit - Tunisia

Product Description

The Reverse Osmosis (RO) process uses a high pressure pump to force water through a special membrane which provides pure water and leaves the dissolved impurities to be flushed to waste.

The BWRO unit was completed with pre and post treatment: multi-media filter, antiscalant chemical dosing, and post chlorination dosing system. The unit was selected from our RO-400 Series, model number BW-43K-1680-3.It produces 30gpm of drinking water with TDS less than 100 mg/L.


Since the time of its start-up in July 2008, the plants have been running smoothly with minimal trouble-shooting.


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 supplied an industrial reverse osmosis unit for brackish water treatment (BWRO system) for major water treatment company in Tunisia. The capacity of this brackish water reverse osmosis unit is 43,000gpd product water at 4,500ppm feed TDS.

    Very compact design and fitted well in our small space inside the facility room. It produces low TDS water consistently
