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
