Sludge Dewatering Centrifuge

A sludge dewatering centrifuge is a specialized piece of equipment used in wastewater treatment plants, industrial processes, and other applications where there’s a need to separate solids from liquids efficiently. Sludge is a semi-solid material produced during the treatment of wastewater, and dewatering is the process of removing water from this sludge to reduce its volume and make it easier to handle and dispose of. The centrifuge works on the principle of centrifugal force, which is the force exerted on an object moving in a circular path due to its inertia. In a sludge dewatering centrifuge, sludge is fed into a rotating drum or bowl. As the drum rotates at high speed, centrifugal force pushes the solids to the outer edge of the drum, while the liquid (water) is forced towards the center. The separated liquid is typically discharged through a separate outlet, leaving behind dewatered sludge cake on the inner wall of the drum. This dewatered sludge cake has a much higher solid content and lower moisture content compared to the original sludge, making it easier and more cost-effective to dispose of or further process. Sludge dewatering centrifuges come in various types, including decanter centrifuges, disk-stack centrifuges, and basket centrifuges, each with its own advantages and applications. Decanter centrifuges, for example, are commonly used for thickening and dewatering applications in wastewater treatment plants due to their continuous operation and high throughput capabilities. With our expertise and how we develop our equipment, using the best material there is to offer. GN uses duplex stainless steel SS2205 and SS2304 for the casting which is better than the SS304 and SS316. Also flexible pond depth adjustment for different material separation. The air-operated spring for assisting open of the cover with safety locking system. Our centrifuges go through three stages balancing process to maximize balancing of the centrifuge. It goes through a low speed of 1800 RPM balancing and real operation high speed balancing as well. The internal parts such as the screw is protected by interchangeable tungsten carbide tiles for longer life and easy maintenance. Also the screw is made up of stainless steel with heat treatment and the opening impeller will improve the centrifuge capacity. It comes with the option of single lead or double lead screw. GN centrifuge is well used over the world and is being required by a lot more operations due to its cost and the results of its operation.
