In the Middle East, fresh water is becoming more and more difficult and expensive to obtain. As a result, countries are investing in alternatives in water purification such as reverse osmosis and desalination.
In May 2007, Pure Aqua successfully supplied a water treatment package consisting of a reverse osmosis (RO) system to produce 200 gpm of product from 250 gpm feed, antiscalant chemical dosing, perchlorination chemical dosing, acid injection and dechlorination dosing systems.
Feedwater to the system is processed water with raw water TDS of about 1,500 ppm. The system design was based on high rejection of TFC spiral-wound low-fouling membranes.
The RO system was selected from Pure Aqua’s RO-500 Series, model number BW-360K-8680-3. It produces 200 gpm of drinking water with TDS less than 100 mg/L.
The RO unit consists of 5-micron cartridge filters to reduce the feed water silt density index and to limit the SS to 5-micron size.
