Funnel-Shaped Secondary Sedimentation tank

A privat brewery required a funnel-shaped secondary sedimentation tank made from stainless steel.

Stainless steel funnel-shaped tank

The customer from the beverage industy decided for the funnel-shaped tank also called "Dortmund tank" in high quality stainless steel 1.4301. So Stallkamp planned and built this funnel-shaped steel tank in a segment-like design with screwed stainless steel shells. The tank is based on a steel construction.

The difference between the funnel-shaped tank and common tanks is the perfusion. The sewage water of the industial company is pumped into the company-owned WWTP. In the funnel-shaped tanks, the sewage is vertically perfused (bottom-up principle). The sedimentation takes place on the funnel-shaped walls. Due to its incline the sludge comes down the walls and is collected in the spire of the tank. The suction of the sludge is very easy.
