Twin-screw extruder DSP 205

The Doppstadt Screw Press 205 is designed for liquid-solid separation of biogenic waste. During this process the bioavailable organic fraction of the input material is concentrated in the liquid phase (filtrate). The filtrate is than used as a substrate to produce biogas using wet fermentation. According to the application the retentate can be composted or directly used as RDF. Usually the filtrate is pumpable and can be diluted by adding process water if necessary. The throughput depends mainly on the input material, the feeding and further factors. It averages between 10 and 12 t/h with a maximum of up to 20 t/h.
