The fully automatic SBR decanter is a precision effluent discharge device engineered for sequencing batch reactor wastewater treatment systems. It automatically removes clarified supernatant from the reactor tank while keeping the settled sludge bed completely undisturbed, delivering consistently high effluent quality with zero manual intervention. Built for round-the-clock municipal and industrial duty, this decanter combines a robust stainless steel structure with intelligent PLC control to guarantee reliable operation over decades of service.

• Fully Automatic Operation: PLC and timer based control cycles the decanting sequence automatically, eliminating manual supervision and operator error.
• Stable Effluent Quality: The submerged weir design draws clarified water from below the surface, preventing scum, foam and floating solids from entering the discharge.
• Corrosion Resistant Build: Wetted parts are fabricated from SS304 or SS316L stainless steel to withstand aggressive wastewater environments.
• Adjustable Decanting Depth: Decanting depth and speed can be precisely tuned to match variable influent loads and sludge levels.
• Anti Vortex Protection: Integrated anti-vortex and anti-floating structures keep the decanter stable during high flow periods.
• Low Maintenance Design: Minimal moving parts, sealed bearings and a simple lifting mechanism reduce service intervals and lifetime costs.

During the decant phase, the PLC activates the electric actuator, lowering the decanter arm smoothly into the tank until the weir reaches the preset water level. Clarified supernatant flows over the weir into the discharge pipe while floating scum remains trapped on the surface. When the level drops to the set point, the arm lifts automatically and the reactor advances to the next treatment phase, ensuring a complete, repeatable cycle every time.

Each decanter is factory tested for weir level accuracy and actuator travel before shipping, then protected with anti-rust film and export grade wooden crates. We provide installation drawings, commissioning support and a 12 month warranty, with spare parts available worldwide.

Our fully automatic decanter has been installed in hundreds of SBR plants across Asia, Europe and Latin America. The combination of precise PLC control, corrosion resistant construction and field proven reliability makes it the preferred choice for operators who demand consistent effluent standards with minimal attention.
