Energy Efficient System for Desalination of Sea-water: "Clean water is becoming scarce and until now the cost of desalination has been a barrier to exploiting seawater. However, a Danish company, HOH Water Supply (HOH), specialising in water technology, has overcome this barrier and invented a new method, which halves the energy consumption of desalination plants. The method, based on existing membrane technology, makes it possible to recycle 95% of the pressure used for pumping sea water through the membrane system. Thus the energy consumption at the desalination plant's pumps and operations are cut from about 7 kWh/m3 of water to 3-4 kWh/m3 of desalinated water. The new Energy Recovery System (ERS) has been developed by an independent engineer in co-operation with HOH. "  9:57:23 AM  permalink
