A rotary energy recovery device (RERD), as the energy saving equipment of seawater desalination system, has a great significance on reducing the energy consumption and permeate cost of the system. The high or low energy recovery efficiency directly determines whether the engineering application of the RERD can be widely used. In this paper, firstly, based on the calculation formula of energy recovery...
A rotary energy recovery device (RERD) is widely used in a reverse osmosis desalination system. In order to maintain the device running in an available torque and obtaining a long service life, a portion of high pressure seawater is usually sacrificed to work as lubrication to reduce the friction torque of the device. However, when using such method, a certain amount of energy recovery efficiency...
