How Reverse Osmosis Water Purification Systems Work

Reverse Osmosis

* Reverse osmosis (RO) is a purification technology that uses a semi-permeable membrane. This membrane-technology is not properly a filtration method.* In RO, an applied pressure is used to overcome osmotic pressure, a colligative properties, that is driven by chemical potential, a thermodynamic parameter. * RO can remove many types of molecules and ions from solutions and is used in both industrial processes and to produce potable water.* 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 the solvent) to pass freely.* Osmosis is a natural process. When two liquids of different concentration are separated by a semipermeable membrane, the fluid has a tendency to move from low to high solute concentrations for chemical potential equilibrium.

Reverse Osmosis Water Purification Systems Work

* Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). * This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. * The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. * These impurities and contaminates are flushed down the drain.* Ultimately, the factors that affect the performance of a ro system are: * Incoming water pressure * Water Temperature * Type and number of total dissolved solids (TDS) in the tap water * The quality of the filters and membranes used in the RO System
