The practical course is conducted as a block course and lasts for 1 week. There are simple but typical methods for chemical analysis for water, sewage, soil and waste taught, which serve the students as the basis for their later work in this area.
In this practical course for example the Institutes of Wastewater Management and Water Protection (IAG), Environmental Technology and Energy Economics(IUE), Water Resources and Water Supply (IWW) are involved. In the following examples of experiments and methods taught in the course are summarized:
Surface waters: sampling of water and sediment
Determination of the pH-value
Determination of the redox potential
Determination of a heavy metal (Zn)
Acid neutralizing capacity (sediment)
Flocculation or co-precipitation of water-suspended titanium dioxide particles
Precipitation of phosphate with Fe3 +
determine the toxicity of wastewater componentsagainst bacteria
denitrification
Electrical conductivity
Acid and base capacity (m-and p-value)
Determination of permanent gases (H2, O2, N2, CO2, CH4) in Landfill Gas
Determining a grading curve by screens
Determination of volatile organic acids and the total content of inorganic carbonate (FOS / TAC) by means of pH titration in samples from biogas plants
