Sewage Treatment Plant
Field trip with Ferdinand Schanz on
Tuesday, December 19, 2000
Waste water from households and from
industries are treated before they are allowed to be released into
the natural hydrological cycle again. The purpose of the treatment
is
- to remove solid matter and toxic compounds
- to minimize the amount of oxidizable carbon in the
water
- to lower the phosphate concentration
- to cycle nitrogen back into the atmospheric sink and
- to anaerobically convert carbon compounds into methane
Microbes play essential roles in waste water
treatment. The field trip will illustrate the microbial processes
in action and give a good overview of the technical layout of a
sewage treatment plant as well as the theoretical background of
the individual treatment steps.
