Desalination plants, and RO (Reverse Osmosis) process in particular, need efficient and reliable solutions. RO process is now the leading technology used to remove a large part of contaminants from water by pushing it through a semi-permeable membrane (with the pressure used, water is to cross the membrane and thus separated from the salt ). Thanks to this technique more than 95% of dissolved salt is separated from the liquid. ARGAL offers AODD and centrifugal pumps entirely made of fiberglass with ideal characteristics to operate in RO applications: very high resistance to corrosion, robustness and capacity to load large volumes of sea water.
