As of the end of 2011, China's seawater desalination capacity reached 660 kilotons per day, and will hit 2.2-2.6 million tons per day in 2015. In recent years, global collaboration in the water treatment engineering field has expanded the Chinese seawater desalination market. This has included Veolia Water, which entered the Chinese water treatment market early in 1997 and now has over 15 projects in China, mainly in Tianjin, Shanghai, Beijing, Shandong and Shaanxi. ProMinent started in the Chinese seawater desalination market in 2001, and has now six completed seawater desalination projects. Israel Desalination Enterprises (IDE) Technologies entered the Chinese market in 2007 and has constructed one plant in Tianjin. Hyflux arrived in 2009 and has now set up the Tianjin Dagang Seawater Desalination Plant. Aqualyng began the construction of a plant in 2010 and now has the desalination project in Tangshan, Hebei. The report adds that Chinese seawater desalination engineering companies have had less impact, although China Shipbuilding Industry Corporation, ZhongHe Seawater Desalination Engineering Co., Ltd. and Wuhan Kaidi Water Service Co., Ltd are making some progress. In terms of seawater desalination equipment, China relies mainly on international suppliers. Reverse osmosis membranes technology has seen its market share rise from 3% in 2005 to around 15% in 2010.
