ZeeWeed MBR Process

Membrane Bio-Reactor: Sewage to Boiler feed!

Reinforced UF membrane: Absolute barrier for treatment/removal; Higher life

Higher MLSS: Smaller footprint/Layout– ideal for retrofit

Improved control: Improved degradation of complex organics & nutrients

Proven Process: Minimal pre-treatment and fewer cleaning chemicals

Modular: Easy to expand

Automated: Operational simplicity with potential for remote monitoring
