The Unit of Environmental Engineering at University of Innsbruck conducts lab-scale experiments on the anaerobic digestion (AD) of organic wastes. Continuous AD experiments in lab-scale are an adequate option to simulate full-scale AD processes. Six fully equipped lab-scale biogas reactors (working volume 6 liter each) were built to enable nearly fully automated AD experiments. Siemens supplied the entire automation system for the biogas reactors. 

Siemens supplied the automation system for the six lab-scale biogas reactors (based on CPU Siemens ET 200SP). The control units’ tasks are:   

• Substrate feeding   
• Digestate discharge 
• Process data acquisition (pressure, temperature, gas quantities)     
•  Reactor heating control   - Reactor mixing control
