2) US: California
Guidelines introduced this May for seawater desalination plants by the California State Water Resources Control Board have been called technically and environmentally unjustified by an industry expert. Former International Desalination Association president Randy Truby said California's new guidelines, which give the State authority over desalination intakes and discharges, are more stringent than anywhere in the world. The State guidelines will require an organisation to explore using a subsurface intake, and if it is not feasible, to seek a permit for an open intake. However, Truby said this could be a technical challenge and add millions (conceivably hundreds of millions) of dollars to the cost of any seawater desalination system. Read full article on page 30.

Israeli company Mapal Green Energy, developers of the floating fine bubble aeration system (FFBA), has been floated on the Alternative Investment Market (AIM) -- a sub-market of the London Stock Exchange. In a statement, the company said regulator Ofwat's Asset Management Plan (AMP6) in April presented that company with its "biggest opportunity to date". This requires water utilities to focus on the total operating cost of the plant, including maintenance and energy use, rather than capital cost.
4) Germany
A Zero Liquid Discharge (ZLD) system has been launched by the Aquarion Group. Called the ZLD.eCO2, the company claimed it will be the "lowest cost ZLD system" available today and that it requires 20% less energy. The process uses a high-pressure reverse osmosis stage that uses Circular Disc (CD) Module technology developed by Membran Filtrations Technik (MFT), one of the Aquarion Group's companies.
5) Singapore
Asia water hub Singapore has started work on a project that will see food waste co-digested with sludge with the aim to produce more biogas. Using technology from Anaergia, water sludge from the Ulu Pandan Water Reclamation Plant will be mixed with food waste collected from the Clementi district and treated in a co-digestion demonstration facility. If successful, the process -- set to completed by September 2015 - could potentially be implemented at the future Tuas Water Reclamation Plant and NEA's Integrated Waste Management Facility.
