Chemical, Pharmaceutical and Cosmetics Industry: 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 oen lack important nutrients for the microbes involved in the degradation. Depending on the type of product, for example, shampoos, the wastewater may be rich in detergents or tensides and may tend to very strong foaming. Silicones may damage the equipment and components used. Besides, the products of this industry are oen manufactured in campaigns or batch processes, which may lead to changes in the wastewater composition almost every hour.

All these aspects demonstrate the particular requirements for a plant to treat such effluents, i.e. requirements which can oen not be fulfilled by using conventional 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 life-time possible.
