„CombO3Carb“

Since October 2019, in cooperation with the companies Huber SE and ProMinent GmbH, a semi-technical test plant has been supervised by the Wastewater Management Department at the Bickenbach wastewater treatment plant of the Bickenbach/Seeheim-Jugenheim wastewater association with the aim of further purifying the wastewater treatment plant effluent. The focus of the investigation is a comparison of sole activated carbon filtration in continuously operated activated carbon filters with the combination of ozonation and subsequent activated carbon filtration with regard to the removal of conventional wastewater parameters as well as anthropogenic trace substances, such as pharmaceuticals and other chemicals. Furthermore, the formation of the carcinogenic oxidation by-product bromate by ozonation is investigated.
