The existing chemical treatment plant at Elverum municipality in Norway needed an upgrade in order to handle increased load and stringent demands.
Considerable food industrial activities resulted in temporary overload and sludge handling problems. An upgrade of the plant was needed and the new plant was also expected tbe designed for easy future upgrade of the biological stage. A fl exible and robust biological process with a separation stage capable of handling large load variations was needed. The Kaldnes MBBR technology followed by DAF was chosen.
