This stainless steel anti floating SBR decanter is purpose built for sludge dewatering systems and SBR process basins where floating sludge and scum must never enter the discharge. The decanter arm is held firmly in position by a heavy counterweight and guide rail assembly, preventing any upward drift even during violent aeration or high turbulence. Its adjustable weir allows operators to skim the clearest water layer, protecting downstream sludge dewatering equipment and improving overall plant efficiency.

• Anti Floating Structure: Counterweighted arm and guide rails lock the decanter in place, eliminating unwanted buoyancy during aeration.
• Adjustable Weir Height: The overflow weir can be raised or lowered in minutes to follow changing water levels and sludge blankets.
• Premium Stainless Steel: Full SS316L wetted construction resists chlorides, acids and abrasive sludge particles.
• Clean Effluent Guarantee: Surface skimming action excludes scum, oil and floating sludge from the discharge stream.
• Sealed Discharge Pipe: Leak proof rotary joints and flexible hoses prevent air entrainment and odor release.
• Quick Installation: Preassembled modules bolt directly onto existing tank walls or walkways.

The decanter rests at its standby position above the water surface during fill and aeration phases. When decanting begins, the drive unit lowers the arm until the adjustable weir submerges to the preset depth. Water flows gently over the weir and through the sealed discharge pipe, while the anti floating mechanism holds the assembly steady. The control system raises the arm automatically once the target level is reached, ready for the next cycle.

• SBR sludge dewatering pretreatment
• Municipal sewage treatment plants
• Industrial wastewater neutralization basins
• Oxidation ditch and batch reactor systems
• Lagoon and storage tank supernatant removal

Units are delivered with anti corrosion film, wooden crate export packaging and full assembly documentation. Our engineers provide remote commissioning guidance, and a one year warranty covers the drive unit, seals and control components.

Sludge carryover is the number one cause of poor effluent in SBR plants, and our anti floating design directly targets that failure point. With thousands of operating hours logged in aggressive industrial wastewater, this decanter is trusted by municipal utilities and EPC contractors who cannot afford downtime.
