Today we visited the wastewater treatment plant Dresden-Kaditz. Although the weather conditions were not beautiful with wind and rain, the EM40 course participants still happily visited the unit. This unit, as the only municipal sewage treatment plant in the area, has a long history but is maintained well and orderly. Although conventional sewage treatment technology is used, the plant is unique in its design / operation and management. Moreover the processing indicators can meet the management requirements.

Mr. Lucke, the head of the environmental analysis laboratory at the wastewater treatment plant, guided us along the treatment process, and explained the different treatment steps from inflow to coarse and fine screens to the different clarification tanks and sludge treatment. Seeing the huge groundwater pipes, we could feel our gap with Germany not only on the ground, more perhaps we can not see the place. During the visit, the participants were able to ask questions about the treatment process, the rainwater impact，and so on.
