The customer opted for a quickly available leasing system, which the ClearFox® team installed within a very short time. This consisted of four container modules, which included screening, a buffer, a fixed bed biological reactor and a secondary clarifier as a lamella clarifier. The screening first removes all coarse material such as straw and small stones from the wastewater. From there, it enters a mixing and equalisation tank consisting of two hydraulically connected tank containers. A pump feeds the system so that the wastewater for dairy wastewater treatment can flow freely through the biology and the secondary clarifier.
