Spent vegetable oils and deep-frying fats are reconditioned in a Biodiesel Plant. The Multichopper reduces large solids to enable them to be separated easily in the downstream processes. The cleaned oils and fats are pumped to large Diesel-Engines driving generators for energy production. The Multichopper is handling a range of 400 usgpm with a maximum temperature of 140 °F.

In a Wastewater Treatment Plant the thickened sludge is pumped to a centrifuge. The sludge contains large quantities of solids, fibers and rags. To avoid blockages to the centrifuge and to protect the pumps, a Multichopper P300-I was installed in the suction line of the Börger pumps. Fibers, solids and rags in the sludge are chopped down and within the same operation the sludge is homogenized.

Food and garden waste are delivered to a biogas plant and are mixed with liquid. The Börger Multichopper and a Börger Multicrusher are installed to chop the solids and homogenize the product. Börger pumps transport the mass to an anaerobic digester. With the combination of the both Börger chopping machines the required solids size necessary for biogas plants are achieved.

In a municipal sewage treatment plant the wastewater is filtered by use of membrane technology. The membranes separate the sewage into permeate (filtered water) and sludge. The sludge is temporarily stored in large tanks. A sludge loading station equipped with a Börger Multichopper and a Rotary Lobe Pump will fill up tankers in minimal time for transfer to a dewatering station. The Multichopper protects the pump and the downstream dewatering equipment by reducing the solids size.
