Our Expertise

The Naqa’a desalination, Seawater Reverse Osmosis (SWRO) technology produces up to 150 MIGD potable water, equivalent to 681,900 m3/day. The principal project components include a 600m seawater open channel intake, a 3.6 km piped outfall, RO plant and potable water storage tanks.

The facility has a seawater intake and pumping system which has a screening and filtration system. In order to ensure the seawater is of a suitably high quality for use in the RO Plant, the pre-treatment is composed of coagulation, dosing and flocculation, high-rate Dissolved Air Flotation (DAF) and Dual Media Filters (DMF).

How We Do It

The SWRO uses the following key stages to produce desalinated water:

  • Seawater system
  • Pre-treatment system
  • Treatment System/ Reverse Osmosis
  • Water quality instrumentation for SWRO
The Reverse Osmosis (RO) plant performs the main function of separating the seawater into two streams by removing the salt from the seawater. The separation is achieved by pushing the water through membranes, with high pressure being used in the process. These two streams include,
1. The permeate - which has passed through the membrane and has had most of the dissolved constituents removed
2. The remaining brine -which contains dissolved solids.
The seawater concentrate/brine is returned to the sea to meet UAE Federal and Lenders requirements, while the permeate will be treated in a second pass. The wastewater streams will be treated on site and no sludge will be disposed to the sea.

“The natural environment sustains the life of all beings universally.”
