Bucher Unipektin Dewatering to the limit Bucher presses provide the superior technology for processing municipal and industrial sludge to yield filter cake with the lowest possible moisture content. Using common additives, sludge may be mechanically dewatered to the limit that is technically possible. The high performance levels of the Bucher press have been demonstrated in comparative trials with other dewatering technologies. Dry substance (DS) values of up to 50% W/W have been achieved. Filter Cover Filtercake Drainage Core The Bucher press is a hydraulically driven cylinder-piston...

High performance through proven methods A complete pressing cycle consists of a filling, pressing and a automatic emptyng phase. A complete cycle takes 70 – 120 minutes depending on the drainage characteristics of the sludge. 1) The press volume is filled up by using a pump. 2 Pressing 2) 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) The press piston is pulled back. The slow rotation of the cylinder and movement of the drainage elements allows the filter cake to...

Operation safety through self-optimizing controls Maximum dewatering performance is achieved with self-optimising controls. The operator may select the degree of dewatering or the pressing time. TR Filterkuchen Filling pump in operation Dewatering process Dry substance content of the filter cake Dewatering progression 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...

Bucher Unipektin Maximal dewatering results in minimal disposal costs The drainage characteristics of a sludge depends to a largely on its composition. The maximum dry substance (DS) achievable through mechanical methods is determined primarily by the content of extra-cellular polymer substances (EPS). The bound water can only be removed by denaturing before mechanical dewatering or by thermal drying. Thermal drying Loss in drying = 55% H2O on organic Mechanical dewatering Loss in drying = 65% H2 O on organic With the Bucher press, the maximum possible dry substance content is achieved for...
