Singapore - Pilot tests aimed at producing recycled water more cheaply will start in April, the Public Utilities Board (PUB) said on Tuesday. The work will be carried out by Japanese companies Nitto Denko and Mitsubishi Rayon Engineering following an agreement with the national water agency. Membrane bioreactors developed by the firms merge conventional filter systems, which separate dirt from pure water, with biological ones using waste-eating bacteria, PUB chief executive Khoo Teng Chye said in remarks published in The Straits Times. Combining the two parts of the process is expected to lower production costs of "Newater," the name for Singapore's reclaimed water. With the new technology housed in a more compact unit, space savings of 40 per cent are expected. "Removing bulky equipment helps land-scarce Singapore and offers great potential for rural areas ... in China and India which don't have access to clean water, said Nitto Denko regional Manager James Iong. The companies plan to run 10,000 cubic metres of water a day through a demonstration plant before commercialization.
