Decanter-SBR

SBR Decanter System

Our SBR Decanter System is a precision-engineered unit for Sequencing Batch Reactor (SBR) plants, designed to withdraw clear supernatant water without disturbing settled sludge. Built for reliability and smooth operation, it ensures consistent effluent quality across varying load conditions.

Decanter Types

• Floating Decanter - Flexible operation with buoyant support, ideal for                                     variable water levels.
• Fixed Pivot (Hinged) Decanter - Mechanically driven, stable and suitable for                                                         medium to large plants.
• Motorized / Automatic Decanter - Controlled decanting with                                                            actuator-based movement for precise                                                            operation.

Design & Technical Parameters

• Flow Capacity: 10 KLD to 5000+ KLD
• Decant Rate: 5 – 15 m³/hr per unit (customized as per basin size)
• Decant Depth: 300 mm to 600 mm (adjustable)
• Weir Loading Rate: ≤ 10 m³/hr/m
• Operating Cycle: Intermittent (SBR cycle based)
• Turndown Capability: Designed for variable inflow conditions

Typical Size Range

• Decanter Pipe Diameter: 100 NB to 400 NB
• Weir Length: 0.5 m to 4.0 m
• Basin Compatibility: Up to 20 m tank diameter / equivalent volume

Mechanical & Functional Features

• Non-turbulent decanting to avoid sludge carryover
• Scum baffle / guard to prevent floating matter entry
• Flexible hose / swivel joint (for floating type)
• Actuator / gearbox driven rotation (for fixed type)
• Smooth start-stop operation with low RPM drive system
