HCMC – Doosan Heavy Industries Vietnam (Doosan Vina) has sent its first shipment of the Shoaiba-4 seawater reverse osmosis desalination project to Saudi Arabia, as part of a US$430-million contract with Saudi Arabia’s Saline Water Conversion Corporation (SWCC) signed last year, the Vietnam News Agency reported.

The first shipment weighs 566 tons, and includes 12 “Made-in-Vietnam” desalination pressure units, which are 6.4 meters high and wide and 8.3 meters long, along with seven re-mineralization tanks which are 5.6 meters tall and wide and 10.6 meters long, to re-mineralize desalinated water.

According to Doosan Vina, its equipment uses a water purification technology, known as reverse osmosis, which forces seawater, under great pressure, through semipermeable membranes that allow fresh water to pass, but filters out salt and other impurities.

In 2017, leading South Korean group Doosan and SWCC agreed to jointly deliver the US$430-million membrane-based seawater desalination project, aimed at supplying potable water for some five million residents in Jeddah, Saudi Arabia’s second largest city.

The project is divided into four shipments, with the next three shipments scheduled for late August, September, and December. The first shipment, which departed from Doosan Vina’s port on July 19, is expected to reach its destination – SWCC, 50 miles south of Jeddah – in about three weeks.

Given the large scale of the project, Doosan Vina and other Doosan subsidiaries are working together to speed up its being carried out, with Doosan Vina being tasked with manufacturing 1,727 tons of desalination equipment.

Once the Shoaiba-4 desalination plant is operational, it would produce 400,000 cubic meters of fresh water per day, or 146 billion liters per year, which is equal to 58,400 Olympic-size swimming pools.
