Dechant Mechanism (Decanting System)
Primarily used in Sequencing Batch Reactors (SBRs) for municipal and industrial wastewater treatment, batch sedimentation tanks, and lagoon-based treatment systems.
Unique Features
Floating decanter selectively withdraws clarified effluent from the top layer of SBR/batch tanks
Prevents disturbance of settled sludge during decanting phase
Telescopic or swing-arm designs adapt to variable water levels
Integrated scum guard prevents floating solids from being discharged
Corrosion-resistant materials (HDPE, FRP, SS316) for long service life
Can be coupled with level sensors for automated operation
Frequently asked questions
In an SBR (Sequencing Batch Reactor), the decanting mechanism withdraws the clarified treated water from the upper zone of the reactor after the sedimentation phase, without disturbing the settled sludge blanket at the bottom.
The floating decanter rises and falls with the water level, always withdrawing water from just below the surface. An integrated scum guard prevents floating solids from entering, while the submerged inlet keeps a safety margin above the sludge blanket.
Decanters are typically fabricated from HDPE or FRP for floats and arms, with SS304/SS316 for inlet screens and structural components. These materials offer excellent resistance to municipal and industrial effluents.
Yes, most swing-arm and telescopic decanter designs can be retrofitted to existing rectangular or circular batch tanks with minimal civil modifications, making them a cost-effective upgrade for improving effluent quality in older plants.
