Welcome to ARA PUSTERTAL AG

Clean Water - Clean Environment

We operate the five sewage treatment plants, the main collector in Pustertal and the sewage sludge drying and incineration plant on behalf of the Pustertal Wastewater Consortium.
We treat the wastewater of the entire Pustertal Valley, dispose of the residues and thus ensure that our domestic waters are kept clean.

On our homepage, we would like to give you an insight into our work and give you extensive information about our water, waste water and the disposal of sewage sludge.

Results of the OptDigest research project

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.
