A major waterworks company operates a community sewage treatment plant in conjunction with private companies. The grease sludge extracted from the grease trap is drained and transported to the digestion tower at a biological treatment plant.
Here the grease sludge is stored in a heated tank. It is heated up to 60-65°C to keep it sufficiently fluid able to be pumped. A Boerger Rotary Lobe Pump circulates the grease in the digestion tower when required. The tank with the pump is designed as a mobile unit to be used for feeding digestion towers in different operations. The Boerger Rotary Lobe Pump proved extremely beneficial here with its compact, low-on-space design.
The water works company is very pleased with the Boerger pump. The reliability of the Boerger pump and its long service life made the decision easy for the customer. The water works company now uses BoergerRotary Lobe Pumps in several of its treatment plants.
