Modification of a software for the simulation of
the wastewater temperature to local conditions
on Baden-Württemberg
Heat recovery from wastewater is a topic of rising importance
in Germany. Heat exchangers could be used
to extract thermal energy from the sewer systems.
On the other hand the temperature has an important
influence on the efficiency of the treatment plant. A
reliable prediction of the temperature is therefore vital
if implementation of such systems is planned in a large
scale.
The temperature regime of wastewater in sewers is
complex. Quantities and temperature of raw sewage
and infiltration water, soil temperature and interaction
between water and air in partly filled pipes have to
be considered. A software for the simulation of these
processes has been developed by EAWAG (Dübendorf,
Switzerland). It has not yet been widely used in practice
because essential model parameters have to be
monitored in practice.
Within the project, extensive monitoring of flow rate,
wastewater temperature and soil temperature is planned.
Based on these results basic parameters of the
model will be fitted (e.g. heat-transfer coefficients).
