The Al Dur 2 Reverse Osmosis plant in Bahrain, designed and built by SIDEM, consists of two independent production streams of 25 million Imperial Gallons of drinking water per day.
There is a common seawater intake pumping station that screens and distributes the flow into two separate streams. Each stream of the plant is composed of the following main stages:
• Reverse Osmosis membrane filtration,
• Post- treatment,
• Exportation, and
In the pre-treatment process an innovative combination of dual media pressure filter (DMPF) and cartridge filters (CF) is applied, a technology owned by Veolia. For proper functioning this system requires measurement of the difference in pressure before and after the DMPF.
