The technology emerged from a three- year pilot project started in 2010 at the PUB Variable Salinity Plant in Pasir Ris. PUB has told the Singapore press that it will roll out the Evoqua technology at its Tuas Water Reclamation Plant next year, with the capability to produce up to 4Ml/d. The power requirement using Evoqua technology is about 1.65kWh/m³ to 1.8kWh/m³. PUB hopes to further reduce the amount of energy needed for the process to just 1.5kWh/m³ of desalinated water. With conventional reverse osmosis, 3.5kWh /m³ of electricity is typically needed. The Evoqua technology removes salt ions by electrochemical desalination whereby they are attracted to electrodes of the opposite charge. This energy-efficient method makes desalination a more viable and sustainable alternative said PUB. Singapore currently consumes water at 1,600 Ml/d. The demand could almost double by 2060. Up to 25%r of the current demand is met by desalinated seawater. PUB hopes desalination can continue to supply the same proportion even in the long term when demand goes up. gloBal grEEN groUp SEEkS to carvE carBoN EmISSIoNS oUt of dESalINatIoN The Global Clean Water Desalination Alliance – H 2 O minus CO 2 initiative, launched at the current climate talks in Paris, has called on its 17-nation membership to use clean energy to power coRpoRate changes new desalination plants. The call was part of the alliance's aim to tackle the water-energy nexus and climate change. The alliance aims to find ways to reduce the projected increase in carbon dioxide emissions from desalination by as much as 270 tonnes a year by 2040. It has urged its members to improve the energy efficiency of desalination, upgrade existing plant, increase research and development and demonstration projects, step up the dissemination of innovative technologies, increase capacity building and analysis, and to draw up strong policies and regulatory frameworks. The alliance includes a founder group of more than 80 signatories from government and the public and private sectors. Industries, research institutions, universities and other organizations from Australia, Belgium, China, Comoros, France, Germany, Greece, India, Indonesia, Italy, the Netherlands, LG Chem, a leading global manuf ac turer of petrochemical goods, electronic materials and rechargeable batteries, has launched "LG Water Solutions".
