DUBAI: Dubai Electricity and Water Authority (Dewa) has awarded an international company with a contract for advisory services to develop a new plant to desalinate seawater using reverse osmosis at the Jebel Ali Power Station (JAPS).

“The advisory services contract is worth Dh16.3 million, with a total desalination capacity of 40 million gallons per day that would be operational by April 2020,” said Saeed Mohammed Al Tayer, MD and CEO of Dewa.

“In adherence with the Dubai Clean Energy Strategy 2050, Dewa is working to retrofit existing plants with photovoltaic (PV) solar panels. This will reduce carbon emissions in the future. The plants use multi-stage flash distillation (MSF) technology, and need to be connected to a central solar plant. This includes the Mohammed bin Rashid Al Maktoum solar park. In adherence with its strategy, Dewa has chosen to use reverse osmosis technology which uses about 90 per cent less power than MSF technology,” added Al Tayer.

“In Dubai, our production capacity is 470 million imperial gallons per day (MIGD), of which 25 MIGD is produced using reverse osmosis (RO) technology. In Dubai, most of the plants use MSF technology, and only 6 per cent use RO. MSF desalination is powered by the waste heat and is therefore fuel-free. This means that its carbon footprint is zero,” concluded Al Tayer.
