The Worms site produces perfumes for finished product plants in Europe. For this purpose, raw materials are pumped into mixing containers, homogenized and filled as a finished perfume. Pipeline cleaning is carried out between batch productions to eliminate contamination. This cleaning takes place via a mixing system in which sodium lauryl sulfate as an anionic surfactant is diluted with well water and pumped into the pipelines. The perfume-containing process wastewater - there are 280 SKUs, made from 1200 raw materials - is chemically treated in a splitting plant in order to separate the emulsion again. For this purpose, the waste water is mixed with a fission powder and calcium chloride in a stirred tank, followed by flocculation. The wastewater that requires treatment is separated from the flocculation via a filter fleece and fed to the sewage treatment plant. As part of a project, an open study on optimization or new construction is to be determined.
