Optimierung von Kläranlagen und Biogasanlagen durch Mess- und Automationstechnik sowie Computersimulation

In recent years, an increase in the use of on-line measurements, real-time control and computer-based simulation can be observed in the ?eld of wastewater treatment. On the one hand, major reasons can be found in increasing requirements for wastewater puri?cation caused by stricter environmental protection laws. On the other hand, technologies for instrumentation, control and automation (ICA) have become more powerful and less expensive. Biogas plants gain worldwide increasing importance due to several advantages. However, concerning the equipment most of the existing biogas plants are still low-tech plants. E.g., from the point of view of ICA most biogas plants are still black-box systems. Consequently, practice shows that many biogas plants are operated sub-optimally and/or in critical (load) situations. To solve these problems, ICA equipment as well as computer-based simulation can also be very useful. The working group „Wastwater“ of the University of Applied Sciences Magdeburg-Stendal therefore focuses on the development of real-time control and simulation tools for the optimization of wastewater treatment and biogas plants. This paper presents three research projects on this topic.
