Passavant® Surface aerator Mammutrotor®

The wastewater treatment plant of the sugar refinery in Ochsenfurt have had three floating Mammutrotors from the year 1973, which should be replaced due to heavy wear. After the refurbishment of the first aeriation pond at the beginning of 2014, the second aeriation pond was equipped with new Mammutrotors

Challenge

Two floating Mammutrotors have been custom-built and installed for the project called to refurbish one of the aeration ponds. The second ventilation section was replaced with two floating Mammutrotors with the length of 6 m instead of 7.5 m.

Solution

Since start-up, the Mammutrotors have been running completely satisfied without significant problems.
The technical support provided by the Aqseptence Group complies with the agreements therefore Südzucker certifies the Aqseptence Group the required expertise, efficiency and reliability based to the aforementioned aeration ponds.
