XB Rotary Decanter for SBR Process Supernatant Decanting
Quantitative Drainage No Agitation | All-Stainless Steel Underwater Parts | XB Rotary Decanter | SBR Process Supernatant Decanting
Product Overview
The XB Type Rotary Decanter is specialized core equipment designed specifically for Sequencing Batch Reactor (SBR) activated sludge treatment processes and advanced variations including ICEAS, UNITANK, CASS, and MSBR processes. During cyclic, time-programmed wastewater treatment operations, this decanter safely discharges supernatant liquid after separation from activated sludge during the settling phase.
Extensively used in municipal sewage, chemical, printing and dyeing, and food processing wastewater treatment projects. Available in two main transmission types: XBS-1 (screw transmission) and XBS-2 (electric push rod transmission).

Frequently Asked Questions
What specific wastewater treatment processes is this decanter used for?
Primarily utilized as dedicated core equipment for decanting supernatant during sedimentation phase in SBR (Sequencing Batch Reactor) processes and modified variations including ICEAS, UNITANK, CASS, and MSBR processes.
Will the water flow stir up settled sludge at the bottom of the tank during drainage?
No. The equipment's major advantage is stable, reliable action with no liquid surface agitation. It descends uniformly at set speed to execute quantitative drainage, ensuring steady water flow that never disturbs bottom sludge.
Does this equipment require constant manual supervision on-site?
No. The electrical control section supports frequency converters and PLC control with reserved interface, allowing seamless connection to wastewater plant's central control system for automated remote operation.
