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.
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 for more than 100
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. |
