High performance through proven methods A complete pressing cycle consists of a filling, pressing and an automatic emptyng phase. A complete cycle takes 70 – 120 minutes depending on the drainage characteristics of the sludge. 1 Filling The press volume is filled up by using a pump. 2 Pressing The press piston is moved forward reducing the press volume forcing the liquid through the drainage elements into the filtrate collection chamber at the end of the cylinder. 3 Loosening The press piston is pulled back. The slow rotation of the cylinder and movement of the drainage elements allows the...

Operation safety through self-optimising controls Maximum dewatering performance is achieved with self-optimising controls. The operator may select the degree of dewatering or the pressing time. The press is operated from a user-friendly operator interface with process visualisation. The relevant process data is displayed. The high level of automation combined with the self-optimising controls guarantee maximum operational safety and performance with a minimum of operator input.

Minimal disposal costs by maximum drainage Sludge dewatering is currently facing several challenges which are already being covered by the Bucher press: Increase of energy efficiency The newly developed hydraulics could reduce the HPS energy requirement by 20%. Therefore, depending on the type of sludge, the actual energy requirement for dewatering with HPS technology lies in a range of 20 to 50 kWh/t dry residue. Low backflow load of the filtrate Due to the filtration process used in connection with sludge conditioning, the backflow load of the filtrate by solids will be reduced to a...
