Bucher HPS presses
Hydraulic filter press for the dewatering of municipal and industrial sludge.
The HPS press was developed for the solid-liquid separation of biological substances. This machine is an effective solution for communal and industrial sludge dewatering. The solid content of a suspension may be between 2 and 10%. For a range of performance requirements, there are several machine sizes available.
High degree of dewatering
Low disposal and drying costs
Reliable process and control system
Self-optimising process operation
Continuous operation without supervision
Minimal labour costs
Minimal maintenance costs
The press is designed as a rotating cylinder piston system with hydraulic drive. Between the end of the cylinder and the piston are flexible drainage elements that are fixed and let the filtrate flow from the inside the press.
The pressing process is composed of various steps, including sludge feeding, dewatering by press-cycling, bulking stages, and filter-cake discharge. A complete pressing cycle lasts between 70–120 minutes, depending on the sludge’s capability for dewatering.
