A bowl, screw conveyor, gearbox, drive device, body, and control panel comprise the centrifugal dehydrator.  To dehydrate solids, the bowl and the screw conveyor revolve at different speeds, applying centrifugal force to the sludge pouring into the dehydrator, and the separated liquid flows in the opposite direction of the solids discharge port. It is expelled to the outside via the separate liquid exit.
Centrifugal dehydrator overview
The clever dolphin-shaped centrifugal dehydrator has a compact form, does not take up much space, and can operate automatically. Mechanical parts are composed of high-quality materials that are durable and simple to replace and maintain. The centrifugal dehydrator from ARK is packed with cutting-edge technology and a modern design. Most sewage and wastewater treatment systems, including food processing, pharmaceuticals, water supply and sewage, and physical and chemical industries, can benefit from centrifugal dehydrators.
The centrifugal dehydrator's operation mechanism

It is made up of a bowl and a screw conveyor. They are powered by two motors that spin at separate rates. A feed pump introduces the polymer into the dehydrator. In the pipeline, the polymer is combined with sludge and propelled to rotate at high speeds inside the dehydrator. The dehydrated cake and desorbed filtrate are then separated and discharged using centrifugal force rotating at high speeds.
At the final step of the sewage and wastewater treatment system, centrifugal dehydrators are placed. Depending on the sludge properties, dehydrated cake discharged from the dehydrator can be reused.
After-sales service and quality assurance
Our major priority is always maintenance efficiency. ARK has a staff of skilled technicians who are dedicated to assisting customers both before and after they purchase the machine. We maintain tight quality control throughout the design and manufacturing processes. Furthermore, it ensures the wastewater treatment industry's quality standards.
Sludge dehydrators are designed, manufactured, and installed directly by ARK. Our services include driving instruction tailored to your needs and assisting you in selecting the most suitable model with the highest capacity.
Auxiliary equipment for the centrifugal dehydrator
The operational system is straightforward, consisting of only the polymer dissolving tank, pumping system, and polymer. Customers can use their existing polymer mixing tanks completely or acquire polymer dissolving equipment from ARK.

Design Compact, space-saving design
Usage Suitable for all types of sludge
Drive Automatic operation and easy maintenance
Performance Maintaining stable dehydration cake moisture content

The Benefits of a Centrifugal Dehydrator
  1. ARK centrifugal dehydrators are highly long-lasting and well-made.
