Utilized as an advanced filtration method, reverse osmosis units are high level water treatment units in which high technology means are put into use.
Reverse Osmosis is a water purification process in which feed water is processed through a membranes. This membrane stop contaminated water, cleaning solutions and undissolved materials from passing through. The clean water is sent along to the point of use and the containments are discharged to a drain. The process, combined with pre-filtration, is able to remove 90 to 99.99% of the dissolved impurities that reside in your water.
Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove ions, molecules, and larger particles from drinking 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 species from water, including bacteria, 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. To be “selective”, this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as solvent molecules) to pass freely.
