Stainless Steel SBR Decanter
,Anti Floating Sludge Dewatering Equipment
,Adjustable Weir Municipal Plant Decanter
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.
Key Features- 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.
