Advantages of KUBOTA MBR System

The effluent quality complies with stringent regulations without the need of post-treatment.

Kubota’s MBR permeate can be directly fed to the RO system for reuse so that the CAPEX & OPEX for the additional treatment will not be required.

In retrofit, the capacity of the WWTP can be increased up to 400% with cleaner permeate by using the existing aeration tank.

Overall water tank volumes will be reduced with design MLSS up to 15 g/l and Kubota’s biological design which allows the integrated aeration and membrane tank where air scoring for membranes is counted for biological treatment. This saves the CAPEX & OPEX, and the saved spaces can be used for other purposes.
