The Kwinana Desalination Plant, located south of Perth, Western Australia, turns seawater from Cockburn Sound into nearly 140 megalitres of drinking water per day, supplying the Perth metropolitan area.〔(Perth Seawater Desalination Plant, Seawater Reverse Osmosis (SWRO), Kwinana, Australia )〕 The salt water reverse-osmosis (SWRO) plant was the first of its kind in Australia and covers several acres in an industrial park near the suburb of Kwinana. Electricity for the plant is generated by the 80 MW Emu Downs Wind Farm located in the state's Midwest region near Cervantes. The wind farm contributes 270 GWh/year into the general power grid, more than offsetting the 180 GWh/year requirement from the desalination plant.〔(Australia Turns to Desalination Amid Water Shortage )〕 The desalination plant, with 12 SWRO trains with a capacity of 160 megalitres per day and six BWRO (brackish water) trains delivering a final product of 144 megalitres per day, was expected to have one of the world’s lowest specific energy consumptions, due in part to the use of pressure exchanger energy recovery devices supplied by Energy Recovery Inc. The devices are isobaric chamber types which recover energy in the brine stream and deliver it to water going to the membrane feed at a net transfer efficiency at up to 98%. As a condition of its continued operation, the Perth plant has a comprehensive environmental monitoring program, measuring the seawater intake and brine outfall.〔(Australia's First Big Plant Thinks Green )〕 Excess water from the plant is stored in the hills dams. In early 2008, the plant was shut down on two occasions due to reduced dissolved oxygen levels in Cockburn Sound.〔(Press release ), July 6, 2008〕 ==See also== *List of desalination plants in Australia *Reverse osmosis plant *Seawater desalination in Australia 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Perth Seawater Desalination Plant」の詳細全文を読む スポンサード リンク
