Energy Energy In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton. Common forms of energy include the kinetic energy of a moving object, the potential energy stored by
Dual Work Exchanger Energy Recovery Dual Work Exchanger Energy Recovery The Dual Work Exchanger Energy Recovery (DWEER) is an energy recovery device. In the 1990s developed by DWEER Bermuda and licensed by Calder AG for use in the Caribbean. Seawater reverse osmosis (SWRO) needs high pressure and some of the reject stream can be reused by using this device. According to Calder AG, 97% of the energy in the reject stream is recovered. The DWEER system uses a piston doublechamber reciprocating hydraulically driven pump, and a patented valve system in a high pressure batch process with large pressure vessels, similar to a locomotive, to capture
