Tank combination with digestion tower function
A waste water treatment plant was looking for a stainless steel tank combination for a new technique of gas extraction from digested sludge. Here, a high level tank should surround an inner cylindrical pipe.
The operator of the waste water treatment plant decided in favor of a Börger stainless steel tank type 07.8. The customer was not also convinced by the high quality, but also by the possibility to choose the size as well as the material of the tank individually for each application.
The selected tank is 12 m high and consists of 8 stainless steel liner rings. The liner rings 1 – 6 are made from stainless steel 1.4301, because of the anaerobic fermentation of the area, which is covered with medium. Stainless steel 1.4571 has been selected for the two upper liner rings and the roof, as it is more resistant to chemical gases.
The Börger stainless steel high level tank has been mounted next to the cylindrical pipe, which has already been installed, and has then been lifted over it by crane. With this technique, much time and installation costs could have been saved, because of the better installation conditions.
