Nitto Denko and Kuraray jointly developed a new system for efficient treatment and reutilization of plant effluent. The system is made up of Kuraray’s biotreatment technology that uses bacteria and Nitto Denko’s water treatment film. The new system needs less than half the space required by the existing system and reduces energy consumption by 30%. Because plant effluent has a higher pollution degree than living drainage, it is usually treated with water treatment film after pretreatment. The new system, however, can collect only required bacteria in the surface of particles and cleanse them efficiently with the help of Kuraray’s original technology that uses particles of synthetic resins. Nitto Denko’s water treatment films that prevent taints from sticking are used in the system. Thanks to the high degree of efficiency, the new system does not needs a big water-purifier tank, and it can reduce electric energy. The substantiative test will start in Singapore between June 2011 and February 2012 as a project sponsored by New Energy and Industrial Technology Development Organization. In the test, 50 tons of plant effluent will be treated for reutilization per day. The system is capable enough to treat up to several tens of thousand of tons plant effluent per day as it grows bigger in size.
