Sludge thickeners for wastewater treatment plants
Optimize your wastewater treatment process with a reliable solution that enhances sludge concentration and aids moisture reduction while ensuring efficient gas bubble liberation and flake aggregation.

Thickens and Concentrates Wastewater Sludge
The ISP Sludge Thickeners from WAMGROUP are engineered to effectively concentrate and reduce the water content in sludge across municipal and industrial wastewater treatment applications. Utilizing slow-moving arms and vertical pickets, they enhance sludge aggregation and facilitate gas bubble liberation within a circular tank setup. This robust system can be integrated into existing tanks, and its design features a central steel drive shaft coupled with a reliable epicycloid oil bath gearbox for efficient operation. Suitable for tank diameters up to 18 meters, the system offers optional features like alternative motor protections and control panels.
Ideal for processing dewatered sludge cakes, clarified water, and various industrial by-products, the ISP Sludge Thickeners serve operations in tanneries, paper processing, municipal solid waste handling, and more. Constructed from hot dip-galvanized carbon steel or stainless steel (304L/316L), the equipment ensures corrosion resistance and longevity. It is equipped with features such as scum removal devices and electro-mechanical torque limit switches to enhance functionality. Easy maintenance and installation, even in large-scale continuous operations, make the ISP an indispensable tool for environmental technology facilities focused on improving efficiency and production capabilities.
