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.

The San Candido/Sexten wastewater treatment plant has been in operation for 19 years, so various tasks were due to be carried out to optimise the plant.

We wish you a merry Christmas and a happy new Year!

Because of the Corona pandemic, many things cannot function as usual at the moment. Nevertheless, our sewage treatment plants remain in operation!

Whether for the baby's face, cleaning the bathroom, our buttocks or cleaning the cow's udder - there are cleaning cloths for everything.

ARA Pustertal is a participant in the ICAWER research project.

The aim of the project is to make sewage treatment plants more energy efficient and to solve local problems. This is achieved through the cooperation of universities, sewage plant and energy consultants as well as several sewage associations in Austria and Italy.

This project is supported by the European Regional Development Fund and Interreg V-A Italy-Austria 2014-2020.

The main collector in St. Lorenzen, near the Senni dairy farm, will be repaired this year. The work was awarded by the ARA Pustertal AG in January after appropriate preliminary work, planning and tendering and will now start in March 2019.

Every day 32,153 cubic metres of wastewater are produced in Pustertal. We use clean water for showering, brushing our teeth, rinsing, washing laundry and every time we go to the toilet. Polluted it becomes waste water, which was simply disposed of into the rivers a relatively short time ago. The environment suffered. Today we have five sewage treatment plants in the valley that treat the dirty water and return it clean to the rivers.
