Equipment Advantages:High surface load in sedimentation pond; large water treatment capacity under the same land area.，Especially suitable for old pool expansion, production increase, and technology improvement.

Project Background：A Hebei-based enterprise has seen an increase in wastewater volume, rendering their existing sedimentation pond ineffective for treating all the wastewater. A technical renovation of the sedimentation pond is required without adding new equipment or construction, with the requirement that the surface load of the sedimentation pond be greater than >>0.82m³/㎡·dEnsure the effluent meets the discharge standards.

Original sedimentation pondSV₃₀Under 50% conditions, the surface load is 0.55-0.65 m³/㎡·d, with the effluent from the sedimentation pond frequently containing fine sludge and lumps of mud.

Our company has undergone technical upgrades on some sedimentation ponds, reinstalling the sedimentation pond flow guide devices, and matching sludge recycle pumps, with the upgrade effects being very evident.SV₃₀Under 50% load, the surface loading reaches up to 0.9 m³/㎡·d. The effluent COD, NH3-N, and TN indices from the sedimentation pond are significantly better than those from the unmodified pond, and the effluent color has been notably improved as well.
