US-based Energy Recovery has won a contract to supply its PX Q650 pressure exchangers for a new seawater reverse osmosis desalination plant in Saudi Arabia that is expected to rank among the world’s ten largest. The device, launched in March 2026, has a peak flow of about 147.6 cubic metres per hour and recovers pressure from the high-pressure reject stream to cut pumping energy. Energy Recovery says its PX technology can lower SWRO energy demand by up to 60%; desalination supplies roughly 70% of Saudi drinking water.
