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.
Systems & Process
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. TFC spiral wound membranes have a recovery rate of 80% with an advanced microprocessor control panel and cleaning system.
From a feed TDS of about 1,500 mg/L at a temperature range of 27°C, the system produces 200 gpm of high-quality water at less than 100 ppm. The water produced will be used in the water park area of the Sports Center in boating areas, pools and water slides.
