How can the process of biogas production from wastewater treatment plants be optimized? One of the biggest problems in this process is the formation of foam in the digesters, which leads to reduced biogas production and increased maintenance costs for the plant. A joint research project of Ara Pustertal AG, Atzwanger AG, Stuga KG and Inewa Consulting GmbH looked for causes and solutions. Now results are available.
