A novel and cost-effective approach on preventive
water pollution control
An improvement of water pollution control in the municipal
waste water practice is either achieved long
term by process integrated in-plant measures in order
to reduce the waste water quantity respectively improve
the waste water quality or near-term by costintensive
advanced treatment (end-of-pipe). The generally
fluctuating water quality and quantity results in
extremely varying dirt load peaks the treatment plant
has to cope with, i.e. the waste water treatment plants
rarely work in their optimal range. Temporarily either
the compulsory limit values are exceeded resulting in
potential water pollution or the waste water treatment
plants capacity is not efficiently used. A solution to
this problem can be integrated approach to the entire
waste water system. Often free storage or treatment
capacity is not detected or used.
The objective of a case study of the University of
Stuttgart, Institute of Sanitary Engineering, Water
Quality and Solid Waste Management, is to achieve
a preventive water pollution control by setting up a
sophisticated interaction of industrial indirect dischargers,
municipal waste water treatment plant, sewage
network and storm water treatment. The main idea
is to establish a load controlled concept based both
on online measurement and data from an integrated
dynamic simulation model embracing the complete sewage
system. A major task of the project is to design
this simulation model.
