Bioselect for Separating Plastic Particles from Digestate

By: Boerger

As more biogas plants include prepackaged material in their feed stocks, contamination of the anaerobically digested sludge with plastics can be a significant hurdle to using land application for disposal. For example, in Great Britain all plastic particles larger than 12 mm (0.5 inches) must be removed from the biomass after the fermentation process. Recently a British biogas plant whose feedstock includes corn and food waste turned to Boerger to solve their plastics issue using the Bioselect RC 40.

The Bioselect is a solids/liquid separator that includes Boerger BLUEline rotary lobe pumps for feeding the unit, as well as discharge of the filtrate. To optimize performance of the skid Boerger also provides the controls for the supplied equipment including an intuitive and easy-to-use touch screen HMI.

For the British plant Boerger was able to accommodate several project-specific requirements including ATEX (explosion proof) compliant electric motors and mounting the entire package on a mobile base frame. The mobile base frame allows the skid to be easily moved around the site to maximize the equipment’s usage.

During the anaerobic digestion process the food waste, corn, and biomass are fermented into renewable natural gas and a fluid waste stream. The Bioselect was chosen to remove all particles larger than 12mm, including plastics, from the fluid waste. After several months in operation the Bioselect has outperformed expectations by removing all plastic particles larger than 1 mm while achieving a high solids content in the dewatered solids. The filtrate is then able to be land applied for disposal.
