Decanter Centrifuge Solutions for Wastewater Treatment
ZK SEPARATION’s wastewater decanter centrifuges maintain stable separation performance even with variations in feed solids and flow rate. The system supports high clarification outcomes and offers modular automation options to align with plant-specific operating conditions while helping lower overall operating burden.
Key Features
Engineered for continuous operation to meet the demands of round-the-clock wastewater treatment.
Smart control adapts to shifting flow and solids conditions, reducing routine operator intervention and helping keep the line stable.
Modular design supports scalable capacity or integration with existing treatment trains.
Energy-efficient VFD drive design helps reduce overall power demand versus conventional dewatering approaches.
Key components are constructed from corrosion- and abrasion-resistant stainless materials (e.g., SS316L or duplex grades), making them well suited for harsh wastewater environments.
How Our Wastewater Decanter Centrifuge Works
Feed & Conditioning
Conditioned influent enters the bowl via a stationary feed tube. Polymer dosing can be integrated to promote flocculation and enhance separation stability.
Centrifugal Separation
The rotating bowl generates high centrifugal force, enabling the separation of suspended solids from the liquid phase.
Solids Conveyance
A differential-speed scroll conveyor transports the settled solids to the beach area where dewatering occurs prior to discharge.
Dual Discharge
Clarified liquid exits through the liquid outlets while the dewatered cake is discharged separately for handling and transport.
Engineered for Performance and Reliability
High Treatment Performance
Supports high-quality effluent and effective suspended solids reduction when operated under appropriate feed, dosing, and control parameters.
Advanced Process Control
Intelligent automation continuously optimizes key parameters to maintain stable separation performance despite influent variability.
Reduced Operational Costs
Energy-efficient design and optimized polymer usage help reduce lifecycle costs while simplifying routine operation.
Built for Reliability
Heavy-duty design with corrosion-resistant materials supports dependable, continuous service in demanding wastewater environments.

ZK SEPARATION decanter centrifuges are deployed across municipal and industrial facilities worldwide, helping plants meet discharge requirements while streamlining day-to-day operation.
Municipal Plant Improves Compliance Stability
A municipal wastewater treatment plant adopted a ZK decanter centrifuge for sludge dewatering as part of a compliance upgrade. After commissioning, operators reported more consistent solids capture and cake dryness compared with the previous setup, alongside noticeable reductions in handling effort—supporting reliable alignment with regulatory limits.
