The Rabigh Phase IV desalination project, undertaken by a Chinese enterprise in Saudi Arabia, is in its construction peak. This project will produce 600,000 tons of clean water daily through processes like pre-treatment, high-pressure pumping, reverse osmosis desalination, and post-treatment. The project features large-scale facilities, including dual-media pressure filters, a steel reverse osmosis workshop, and water storage tanks. The core of the reverse osmosis desalination technology is the reverse osmosis membrane, with seawater undergoing multi-level filtration before reaching the membrane. The project has reduced energy consumption to the industry’s lowest level through innovative processes. The undertaking company has extensive experience in the seawater desalination field. Saudi Arabia, a global leader in seawater desalination, is continuously enhancing efficiency through investment and innovation.
