ZK Wastewater Decanter Features and Benefits
Low Investment and Running Costs
For water purification plants and sewage treatment plants, a high-performance water treatment decanter centrifuge is an ideal choice, which has high flexibility toward different kinds of sludges and has greater processing capacity at low concentration (SS 0.5). In the case of low concentration (SS 0.5%), it is not necessary to equip a concentrator to realize the dehydration function, which satisfies the requirements of the process for integrated concentration and dehydration.
Low Infrastructure Cost, Humanization Design
Compared with the conventional filter-type equipment, the high-performance water treatment centrifuge is compact and efficient, covering only about a third of the land. And it is needless to equip auxiliary gas and high-pressure water. ZK wastewater decanter centrifuge feature with simpler pipe structures at the inlet and outlet, fully closed operation, and a more humanized operating environment.
Rich Choice of Models to Meet Different Needs
Whether you operate a water treatment plant scale of 5000 tons per day or less, or a large scale of one million tons per day, you can find the right model configuration in ZK. At the same time, ZK provides turnkey solution (water introduction and discharge, cable laying, mud cake conveying, equipment infrastructure construction and equipment installation, etc.) to solve the problem of disconnection between construction and supplier, and eliminate the worries of customers.
Modular Design, Easy to Operate
Our design philosophy: The requirements on the skills, educational level, and labor intensity of operators should be lower, and one-button start and stop of the control system, fault self-diagnosis, and safety self-protection should be realized.
Automatically Operation without Manual Intervention
ZK high-performance centrifuge is in a mode of automatic and continuous working for feeding-separating-slag/liquid discharging. The whole process requires no human intervention. Multiple sets of equipment require only one inspector which can be concurrently held by other positions. Unlike the plate-and-frame filter, it does not require manual cutting in the sludge discharging process, which greatly alleviated the labor intensity of operators.
Good Manufacturer with Better Services
With strong technical strength and rich engineering experience, we are fully qualified for the turnkey project of the sludge dewatering room. We are also able to provide a design scheme of the sludge dewatering room for owners and design institutes.
BD Board Technology
The screw conveyor adopting BD board technology is the most advanced for reducing the water content and improving the solid recovery rate of activated sludge (organic matter ≥ 40%).
High-dryness Screw Conveyor and Drum Structure
The dehydration of solid particles relies mainly on strong centrifugal force, high-torque screw extrusion force (pushing torque), and ultra-long solid particle dehydration length. ZK wastewater decanter can generate centrifugal force over thousands of G, 30 ~ 50% higher than the screw pushing torque of common centrifuges. The screw pusher torque is higher, and the drum dehydration length is 10 ~ 20% longer than that of common centrifuges as well.

Why Choose ZK Decanter Centrifuge?
The bowl (core component) is made of SAF 2205 duplex stainless steel by centrifugal casting process, and its performance is superior to conventional 304 and 316. All weld joints have undergone flaw detection and thermal treatment, and are provided with certificates of conformity or records for traceability.
The dynamic balance precision of the centrifuge is ≥ Class 2.5, which is superior to the requirement of the standard, so that the centrifuge can be operated smoothly and its longevity is extended. The noise of the complete machine is < 85 dB, the vibration intensity is < 7.1 (load) and 4.5 (no-load). It is equipped with a mechanical and electrical dual overload protection device to ensure safe operation.
Long Service Life
The screw conveyor and bowl adopt of the most advanced, reliable and convenient wear-resistant treatment technology and structure in China. All bearings adopt original imported NSK/SKF bearings. The electric control box is made of electrical elements of famous brands such as Siemens and Schneider.
High Degree of Automation
ZK decanter differential speed automatic control technology can automatically adjust the screw conveyor’s differential speed, to prevent overload and blockage. The complete machine is equipped with bearing temperature sensor and vibration sensor, and is provided with alarms for main motor overload, differential over torque, low differential speed, etc. Meanwhile, its supporting frequency conversion (flameproof) control cabinet can realize automatic start and stop with one key.
