OREANDA-NEWS. Tests so far have shown that the Eco-MBR is able to achieve a high-quantity flux, or quantity of permeated water per membrane surface area, that is more than twice the rate of conventional MBRs. The key is regularly backwashing the membranes with highly concentrated ozonated water to remove virtually all organic foulants, thereby increasing membrane permeability. In addition, the Eco-MBR lowers energy consumption by using a reduced flow rate for air bubbles that are emitted from a blower to clean the membrane surfaces. The Eco-MBR also enables the use of fewer membranes, resulting in smaller plant and system footprints.

Sembcorp, a leading developer, owner and operator of industrial and municipal water plants, selected the Eco-MBR based on the promising results of background tests. Testbedding at Sembcorp's water facilities will enable the Eco-MBR's performance to be proven in an industrial setting ahead of its planned commercialization by 2018.

The collaboration between Mitsubishi Electric and Sembcorp will take place under the umbrella of the Sembcorp Industrial Living Lab, an S$8 million scheme launched by Sembcorp and Singapore's Economic Development Board last year to support the testbedding and commercialization of new R&D projects.
