Learning outcomes

After successful completion of the course, students are able to describe and explain the contents of the lecture, to elucidate advantages of different technologies of anaerobic wastewater / sludge treatment as well as to give simple practical examples.

Subject of course

In biological wastewater treatment, a distinction is made between aerobic and anaerobic treatment methods. In practice, aerobic processes are primarily used for purification of effluents with relatively low concentrations of organic contaminants (e.g. municipal sewage). Anaerobic processes are primarily used in the treatment of sludge and highly concentrated industrial wastewater.

In this lecture, you will be introduced to the microbiological principles, the specific procedures and the fields of application of anaerobic biological wastewater treatment. You will learn about specific parameters for the assessment of industrial wastewater and we will have a look at some interesting industrial wastewater treatment case studies.

The second part of the lecture deals with the treatment and disposal of sludge from municipal biological wastewater treatment plants. This includes the current development of various processes for P-recycling from municipal sewage sludge. Phosphorus, an essential element for all organisms, which was added to the list of critical resources in the EU in 2014, can be recovered from the sludge after a targeted P-removal in the wastewater treatment process (bio-P, precipitation) and used as fertilizer in agriculture.

A further main topic of the lecture is the consumption and production of energy in wastewater treatment plants. Wastewater treatment plants are among the major electricity consumers in many municipalities. You will learn why this is not a necessity and how to prepare and operate wastewater treatment plants without any external energy input or even with an energy surplus that can be sold to the electricity provider.

You will get information on the main sources and sinks of energy in the wastewater and sludge treatment process, learn about the most efficient way to use gas generated during the sludge digestion process and about the pros and cons of co-fermentation, get an idea of what in meant by "Organic Rankine Cycle" and whether the idea of the energy-positive sewage treatment plant can actually be realized. In addition, the importance of wastewater treatment with regard to greenhouse gas emissions is discussed.
