Mitsubishi Electric and Sembcorp Industries to Testbed Ozone Backwashing Energy-Saving Membrane Bioreactor
Mitsubishi Electric Corporation will collaborate with Sembcorp Industries Ltd in late-stage testing of its Ozone Backwashing Energy-Saving Membrane Bioreactor (Eco-MBR), a new technology for low-energy wastewater treatment and water recycling.
According to Mitsubishi Electric, initial tests 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. 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.
The collaboration between Mitsubishi Electric and Sembcorp will take place under the umbrella of the Sembcorp Industrial Living Lab, an $8 million investment launched by Sembcorp and Singapore’s Economic Development Board last year to support the testbedding and commercialization of new R&D projects.
