Abstract:
The construction of an island desalination project is an important measure to ensure the water safety of the military and civilian in offshore islands. The double membrane reverse osmosis (RO) technology with turbine energy recovery device was used in the 1 000 m3/d seawater desalination plant in an island of Paracel Islands. The project situation and process scheme of primary RO desalination system are introduced. The operation results showed that the efficiency of energy recovery device was up to 62% under the condition of 40% recovery rate in the primary RO system. The effect of energy saving is remarkable and the energy consumption of unit water production is 3.34 kW·h/m3.
