Seawater Desalination Project at a Power Plant in Saudi Arabia


This project has a total of 4 seawater desalination systems, and utilizes VONTRON SW8040HR-400 membrane products, with 140 units per set. The raw water sources from the Red Sea, with a designed water production capacity of ≥80m³/h, recovery rate of ≥43%, and seawater TDS ≤ 41170.14mg/L (the concentrate from the secondary RO system returns to the inlet of the primary seawater desalination system).

VONTRON membrane elements were installed and commissioned in 2019, achieving a system desalination rate of 99.36%. Both the water production and desalination rates meet the system design values and remain stable, with good performance during operation.
