Curieau Reverse Osmosis purification

One of the most efficient methods of water purification

  • Excellent way to remove certain unwanted contaminants from the water
  • No ion particles can be allowed to enter through the semipermeable membrane
  • Simple maintenance, which does not require system shutdown


The Curieau Reverse Osmosis (RO) system purifies water by use of a partially permeable membrane to remove ions, unwanted molecules and larger particles from water. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property that is driven by chemical potential differences of the solvent, a thermodynamic parameter. Reverse osmosis can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
