The Fraunhofer Water Systems Alliance has vast experience in developing and optimizing purification processes for municipal and industrial wastewater treatment plants. Systematic analysis and detailed measurements have optimized processes such as nitrification and denitrification in wastewater treatment plants and increased biogas yield. It was often possible to improve the entire operation, saving costs otherwise needed for reconstruction and building alterations.
leads to increases in biogas yield, smaller amounts of sludge and costsavings for sludge disposal.
are especially suitable for treating wastewater highly polluted with organics – often to be found in the food and beverages industries, in slaughterhouses and at airports (de-icing agents).
is a worthwhile process. Besides organic load, wastewater also contains large amounts of nutrients such as nitrogen, phosphor, magnesium, potassium and sulfur. In conventional wastewater purification plants, it takes considerable efforts to eliminate these. The Fraunhofer Water Systems Alliance is developing and optimizing various technologies to recover and recycle these nutrients.
