Online Biomonitoring on the Wastewater Treatment Plants

Wastewater treatment plants are important point sources for micropollutants from com-munal or industrial origin to surface waters. To solve this problem wastewater treatment plants are upgraded with additional cleaning steps in Switzerland. All investigations on wastewater treatment plants are timely limited. But wastewater is dynamic and can change its composition rapidly, especially when industrial waste water is involved.

Together with Swiss applied Centre of Ecotoxicology we investigate the potential of online Biomonitors for a continuous monitoring of wastewaters. Online Biomonitors are interesting, because the as sensors applied organisms (like gammarids) can show the effects of mixtures as well as unknown substances.
