Intermittent Decanted Extended Aeration
An advanced technology of Sequencing Batch Reactor (SBR) combining aeration and sedimentation in the same tank. Extended aeration provides sufficient oxygen to reach endogenous phase, thus small sludge production and high BOD removal. Unique decanter operates with hydraulic principle, controlled by solenoid valve. No moving part, hence easy to maintain.
A type of activated sludge process for the treatment of wastewater. SBR reactors treat wastewater such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter (measured as biochemical oxygen demand (BOD) and chemical oxygen demand (COD)). The treated effluent may be suitable for discharge to surface waters or possibly for use on land.
