During the last 15 years, mechanical-biological wastewater treatment plants in Germany have been increasingly supplemented by filtration plants. Their technology, which is based on the one used for drinking water processing, had to be adapted to the differing circumstances. Companies specialised in filtration, as well as engineering offices are planning these plants. Workers at wastewater treatment plants had to learn how to operate the filters. Not all the necessary adaptations went smoothly. A number of operational problems have occurred during the last few years. Some problems have been analyzed by the Department of Environmental Engineering of the Aachen Technical University (ISA), leading to suggestions for avoiding these mistakes in the future.
