Anaerobic biological purification of highly polluted wastewater

Anaerobic wastewater purification processes are especially suitable for treating wastewater which is highly polluted with organics – often to be found, for example, in the food and beverages industries, in slaughterhouses and at airports (de-icing agents).

Organic carbon compounds are turned into biogas in a bioreactor. Microorganisms are held back with microfilters to increase the production rate. The filtrated water is hygienic and safe so that it can be used to irrigate agricultural areas.
