The BIODOS series of belt presses utilizes a combination of chemical conditioning, gravity drainage and mechanical pressure in a continuous feed system to dewater sludge. The sludge is squeezed between tensioned serpentine belts and a series of decreasing diameter rollers to remove moisture and create a dewatered sludge cake.
BIODOS belt presses are manufactured with a belt width ranging from 0.5 to 3 m and with varying levels of automation. Belt presses can be supplied as a free standing unit or as a part of a complete sludge dewatering package, customized to suite any waste treatment needs.

The BIODOS belt press system is engineered for effective sludge dewatering by integrating chemical treatment, gravity separation, and mechanical compression in a seamless, continuous operation. Sludge is processed between tightly tensioned belts and passed through a series of rollers that gradually reduce in size, efficiently removing water and forming a compact sludge cake.
Designed to accommodate a wide range of applications, BIODOS belt presses are available in widths from 0.5 to 3 meters and can be configured with various levels of automation. Whether as a standalone unit or part of a fully integrated dewatering solution, these systems can be tailored to meet the specific demands of any wastewater treatment facility.
BIODOS belt presses are advanced sludge dewatering machines designed to reduce sludge volume and disposal costs. Utilizing a combination of pre-treatment and multi-stage pressure zones, these systems ensure maximum water removal while maintaining high throughput and operational efficiency. The design ensures consistent performance, even with varying sludge types and concentrations.
Engineered for versatility, BIODOS units are available in a wide range of sizes and configurations. Optional accessories like polymer dosing systems, wash water boosters, and cake conveyors can be added to create a fully automated sludge management line. Their compact footprint and modular design make them ideal for both new installations and upgrades to existing treatment plants.
