Activated sludge treatment with a separation membrane module

An activated sludge treatment process that produces highly transparent treated water by using a liquid-solid separation system with a fine filtration membrane that is submerged in the reaction tank

<Features>
Small footprint
Operationability at high mixed liquor suspended solids (MLSS) concentrations means a compact reaction tank can be used
No primary settling tank, final settling tank, sand filtration, or sterilizing machine
No sludge tank and thickener

High quality treated water
Ninety-nine percent reduction in biochemical oxygen demand (BOD) and more than 80% reduction in total nitrogen (T-N) at six hours hydraulic retention time (HRT)
No suspended solids (SS) or coliform bacteria in effluent

Easy operations & maintenance
Easy control of liquid-solid separation because there is no final settling tank
Easy daily management: daily walk around is all that is necessary
Numerical control of membrane differential pressure, filtered water volume, etc.
