How does ASBR work?

Time based variable volume process

Operates a "Process Cycle"

Process Cycle comprises a sequence of phases :

Filling with influent

React

Settling

Decanting (removing) treated effluent

Fill and Draw

ASBR Process Features

Compartmentalized reactor

Bio-Selector Zone

No Mixers

Hydraulic & Organic Load Equalization

BOD & TSS Oxidation

Nitrification & Denitrification - Total Nitrogen

Biological Phosphorus Removal
