摘要

The column type clarification plant comprises a primary settling tank (20) for discharging coarse impurities, an additional secondary settling tank (26), a trickling filter, and an aeration basin (44) integrated within the plant instead of the secondary settling tank. The clarification plant shows an increased cleaning efficiency based on the integration of the aeration basin, and an energy consumption that is smaller than a comparable pure aeration plant. The cleaning efficiency of the modified- and widened clarification plant corresponds to an aeration basin plant.

The filler material of the trickling filter for increasing the load capacity consists of plastic.
