Dubai Electricity and Water Authority completed 92.4% of SWRO desalination plant, set to open in 2021

Dubai Electricity and Water Authority (DEWA) has finished 92.4 percent of the Seawater Reverse Osmosis (SWRO) desalination plant at Jebel Ali Power Plant and Desalination Complex, the authority reported Monday morning.

The Complex is the fundamental provider of Dubai’s electricity and water services with a significant degree of reliability, efficiency, and quality. The Dh871 million plant has a production capacity of 40 Million Imperial Gallons of Water each Day (MIGD) of desalinated water, to a consortium drove by Spain’s Acciona Agua and Belhasa Six Construct (BeSIX).

Saeed Mohammed Al Tayer, MD and CEO of DEWA, said the project is going as arranged and is relied upon to be finished in Q4 of 2021 to keep up with the excess in production to meet the reserve margin for top water demand.

Al Tayer said DEWA’s installed capacity of desalinated water is 490 MIGD, with top water demand coming to 378 MIGD. DEWA plans to expand its SWRO production capacity to 303 MIGD by 2030; coming to 42 percent rather than its present portion of 13%.

SWRO desalination plants require less energy than Multi-Stage Flash (MSF) plants. The desalinated water production capacity will reach 730 MIGD in 2030. As indicated by DEWA’s methodology, 100% of desalinated water will be created by a spotless energy mix that utilizes both sustainable power and waste heat by 2030.

“This will allow Dubai to surpass global focuses for utilizing clean energy to desalinate water. Expanding the operational efficiency in decoupling desalination from electricity production will save around Dh13 billion and diminish 44 million tons of fossil fuel byproducts by 2030,” said Al Tayer.

Nasser Lootah, leader VP of age division at DEWA, said, interestingly, DEWA executed in ‘K’ station SWRO plant the Dissolved Air Flotation (DAF) framework to treat water and eliminate any poisons before the desalination interaction.

“This enables the desalination process to continue in all conditions especially during red tide when total suspended solids and turbidity reach high levels. The plant is also equipped with a Dual Media Filter (DMF), which filters and improves the quality of seawater feed, thus increasing the lifetime and performance of the reverse osmosis membranes. Moreover, the two-pass reverse osmosis system implemented in this project guarantees a high quality of potable water,” said Lootah.

The SWRO plant is furnished with recuperation gadgets that has a 96 percent efficiency rate. They use the high pressure from the primary pass saline solution/reject stream and move it to a piece of the feed water stream to initially pass bay. This essentially decreases electricity utilization in the high-pressure pump, subsequently improving efficiency of the desalination cycle
