Environmental protection by washing lye cleaning and oil recycling

Certain surface treatment processes in the metal-processing industry require thorough cleaning. Treatment of the cleaning agents used not only provides environmental protection in the long term; it also significantly reduces costs.

Centrifugal separators are suitable for cleaning washing lye. They process the washing lye of a hot defatting bath and the resultant drawing oil from the deep drawing process.
