The Clauen sugar factory of Zuckerverbund Nord installed a new waste water treatment system for the 1995 campaign. For the first time in the sugar industry, a fluidized-bed system was employed for the treatment of highly charged waste water, which had been developed in several stages from laboratory to 10m3-scale by the Braunschweig Sugar Institute and built by Braunschweigische Maschinenbauanstalt (BMA). After about 200 days of operation (two crops and a between-season waste water campaign), the reactor was completely emptied, in order to be able to examine its overall condition. This offers the opportunity for a closing assessment of the system, which summarizes the experiences to date.
