At a two-stage biogas plant, staff were having increasing problems with blockages in an eccentric screw pump due to solids. The pump was installed between the main and secondary fermenter. Various silages are used within the plant (corn, millet, grass, rye) as well as dried chicken manure.
The customer chose a Börger Rotorrake to reduce the solids. The Rotorrake was fitted on the suction side directly in front of the eccentric screw pump.
The operator of the biogas plant is extremely pleased with the chopping yield. No more pump blockages occurred. The Börger Rotorrake's long service life and ease of maintenance continue to impress the customer. He is now considering using additional Börger products for the biogas plant.
