Description:

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
