Energy-saving RO system taps kinetic forces

摘要

The development of energy- saving desalination systems based on pressure exchangers has reduced energy consumption to 2 kWh/m~3, which is the theoretical minimum limit for energy consumption for seawater applications of reverse osmosis. R.O. Kinetic of Tenerife, Canary Islands, has improved upon recent technology advances in pressure exchange-based systems by also harnessing the continuous kinetic cycle of water. The physical principle that serves as the foundation for the system is the "incompressible property of liquids," making it possible to submit a mass of water to a given pressure without expending any energy. Pressure exchangers are used to put this principle into practice.
