Process: Activated sludge plant with extended aeration and floating/ moving fine bubble aeration according to BIOWORKS® design.
On the wastewater treatment plant Wabern in Hessen the aeration system OXIWORKS® including maintenance and cleaning system OXIRISE® has been installed. The aeration system has operational advantages as increasing the oxygen transfer efficiency due to the optimal characteristics of the aeration system leading to lower operation cost. Furthermore the aeration system is easy to maintain. Due to short installation time (there was no need of emptying the basin prior installation) the retrofit could be done very fast and with comparatively low cost.
