Wastewater treatment is a process to convert wastewater – which is water no longer needed or suitable for its most recent use – into an effluent that can be either returned to the water cycle with minimal environmental issues or reused. Treatment means removing impurities from water being treated; and some methods of treatment are applicable to both water and wastewater. The physical infrastructure used for wastewater treatment is called a “wastewater treatment plant” (WWTP).
The global desalination market is a robust and growing one; Global Water Intelligence forecasts US$106 billion in capital expenditure between 2008 and 2016, with the winners being those with development and/or operating contracts and a strong record of low cost delivery.*
