Some product information on reverse osmosis water maker

Reverse osmosis (“RO”) is a water purification technology that uses a semipermeable membrane. Different from a filtration method of desalination and solid suspension treatment, RO applies high pressure to overcome osmotic pressure, a colligative property that is driven by chemical potential, a thermodynamic parameter. RO effectively retains many types of molecules and ions in a solution on the pressurized side of the membrane, while allowing the smaller components (the solvent) to pass through. This method is commonly used in Marine, Offshore O&G and industrial processes to produce potable water.
