Bellmer GmbH
About
Bellmer GmbH of Niefern-Oeschelbronn, Germany, dates to 1842 and remains family-owned in its sixth generation, employing over 900 people at 17 international locations across two divisions, Paper Technology and Separation Technology. The separation business, begun in 1972, builds liquid-solid separation equipment for municipal wastewater, paper, biogas, mining, pharmaceutical, recycling, and food customers. The WinklePress belt filter press applies six dewatering stages of gradually rising pressure; the WinklePress H variant exceeds 60 percent dry solids. The TurboDrain gravity belt thickener, with patented chicanes, is credited with 10 percent less energy, 20 percent less polymer, and 30 percent less water use than competitors. Ten AKUPRESS screw press variants - more than 700 sold - include the municipal BX LL with movable screen basket, while the Cascade combination system, TurboScreen micro filter, disc thickeners, and HC-Pulper biogas equipment complete the line.
Key Products
Flagship belt filter press with six dewatering stages and slowly increasing pressure, optimized roller configuration for higher dry solids content, available in multiple models for municipal, paper, and industrial sludge dewatering.
Market-leading gravity belt thickener with patented chicanes achieving 10% less energy, 20% less polymer, and 30% less water consumption versus competitors for municipal and industrial sludge thickening.
Municipal sludge dewatering screw press with patented movable screen basket for torque control, integrated sedimentation unit, available in multiple sizes for various capacity requirements.
Industrial and paper sludge dewatering screw press achieving up to 70% TS dry content, available in seven sizes from 250mm to 1,400mm screw diameter.
Paper reject handling and recycling screw presses for high dry content applications in paper mills and recycling facilities.
Biogas digester dewatering screw presses for dry and wet anaerobic digestion applications in agricultural and municipal biogas plants.
Biogas wet digester phase separation screw press for separating digestate into solid and liquid fractions for nutrient recovery.
Combined sludge thickening and dewatering system that processes both steps in a single unit, reducing footprint and complexity versus separate TurboDrain and WinklePress installations.
Fine micro filtration screen for process water and wastewater that removes COD and suspended solids without chemical additives using pure mechanical filtration.
Rotary disc thickener for thickening fiber suspensions in paper industry applications, achieving consistent thickening with minimal fiber loss.
High-pressure dewatering press for achieving dry solids contents above 60%, principally for paper sludge and industrial residuals.
High-consistency pulper for biogas applications, breaking down organic substrates for anaerobic digestion and increasing biogas yield.
Water recovery and filtration system for paper machine white water and process water reuse, reducing freshwater consumption.
