Reverse osmosis is the process of forcing a solvent from a region of high solute concentration through a membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute. Concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membrane here is semi permeable, meaning it allows the passage of solvent but not of solute.
High purity water produced by reverse osmosis technology increases energy output and operating efficiency in power plants-two attractive benefits for the competitive power industry. Treatment of water implicitly means changing its physical and mainly its chemical properties by removing undesirable suspended & dissolved impurities of both organic & inorganic nature. The level of chemical dosing involved & method adopted for treatment are according to the end consumers requirement as well as the nature of composition of raw water sources; which are all mainly from surface wells, lakes, rivers of from underground sources such as deep wells in some places from sea.
The specific method adopted such as conventional treatment of flocculation/coagulation, filtration and disinfections, lime soda softening process, permeate filtration, electro dialysis, demineralization, reverse osmosis and others are depends upon the product quality require.Current industry trends are leading power plant operators to adopt reverse osmosis (RO) as a water purification technology that does not require the use of hazardous chemicals and can boost output from gas turbines.
Increasingly, RO is playing a significant role in efficiently pre-treating water for power augmentation. The demand for electricity continues to grow so power plants need to generate more power. The injection of high purity water produced by RO technology into a gas turbine increases output by up to 12%.
Power plants have used coagulation, flocculation and ion exchange beds (cation and anion beds) to create high purity water from many years. These methods purify water, but the technology requires the use of hazardous chemicals, including acid and caustic solutions. Membrane technology, namely RO, is now being used as a viable water purification technology primarily because it does not require the use of hazardous chemicals. This factor, in addition to others, explains why RO technology is replacing ion exchange beds, thereby becoming the predominant water treatment process in power plants.
Based on the Output water quality required, the post treatment process may consist of all or some of the following treatment steps
