Hydraulic filter press for dewatering municipal and industrial sludge
Optimize your sludge management with a robust hydraulic filter press, delivering high-efficiency dewatering for reduced disposal costs and streamlined wastewater operations.

Dewaters and Separates Industrial and Municipal Sludge
The Bucher HPS series from Bucher Unipektin is engineered specifically for the complex task of dewatering municipal and industrial sludge. This hydraulic filter press utilizes a rotating cylinder piston system, ensuring efficient solid-liquid separation via multiple stages: sludge feeding, press-cycling, bulking, and filter-cake discharge. Designed for continuous operation, it significantly reduces labor and maintenance costs with its self-optimizing process control.
Applications span municipal wastewater treatment and industrial sludge management, producing end-products like dewatered sludge cake and recycled wastewater. With models such as the HPS 3007, 6007, 7507, and 12007, the series accommodates a range of processing capacities, handling throughput from 100 to 800 kg of dry residue per hour depending on the model, all while maintaining energy efficiency with optimized power consumption between 10 to 18 kW.
Available with flexible material options, these presses are built for durability and corrosion resistance, ensuring long-term reliability in demanding environments. Additionally, their design supports minimal intervention and cleaning time, further streamlining maintenance operations.
