Digestion tower feeding
The operator of a waste water treatment plant wanted to store the grease collected in the sand trap in the digestion tower to achieve higher levels of gas production. The grease has different degrees of viscosity and is full of very different types of solids. The customer was looking for a robust and low-maintenance design and technology. Here Börger built a stone trap coupled to a chopper. The grease/water mixture then flows into a grease container where the mass is kept homogenized by an agitator controlled by a probe.The grease and water mixture is primed from the sand trap by a tanker and taken for removal. Once there, the mixture is pumped through the pipe via the stone trap using the Börger Rotary Lobe Pump in the tanker. The remainign solids are then chopped in the Börger Multicrusher. An additional Börger Rotary Lobe Pump conveys the mixture from the grease container straight to the digestion tower.
