The treatment of production wastewater

In many cases, wastewater from the production of chemicals, pharmaceuticals or cosmetics is difficult to treat:

  • For an effective biological degradation of organic pollutants, these effluents often lack important nutrients for the microbes involved in the degradation.
  • Depending on the type of production, the wastewater may be rich in detergents or tensides and may tend to very strong foaming.
  • Micropollutants and APIs overstrain conventional sewage treatment plants.
  • The composition and volume of the wastewater change almost every hour due to the production in campaigns.

All these aspects demonstrate the particular requirements for a plant to treat such effluents, i.e. requirements which can often not be fulfilled by using conventional treatment technologies.

WEHRLE plants have been developed for such difficult conditions. Apart from wastewater treatment plants, we also build plants for emulsion splitting, the recovery of materials and process water treatment. All this is rounded off by a customer-oriented service concept making a reliable plant operation, low operation costs and a high plant lifetime possible.
