Welcome to our scientific project webpage gallery, where we showcase some of the exciting images from the Trace&Treat project focused on wastewater post-treatment. Our team is working to develop and test new technologies and methods to improve the quality of wastewater after it has undergone standardized treatment at WWTP.

Here you will find relevant images, graphs, and other visual aids. Our goal is to provide you with a comprehensive understanding of how we can make wastewater treatment more effective and environmentally sustainable. Our work has important implications for public health and the environment, as it can help to reduce the impact of persistent pollutants in the wastewater on aquatic ecosystems and human populations.

We invite you not only to browse our project page gallery but also to learn more about our research on wastewater post-treatment. Thank you for your interest in our work, and we hope that our research inspires you to continue exploring the potential of science to address pressing environmental challenges.

Urban Wastewater conference 2022

During the conference Urban Wastewater in 2022 was presented the main idea and scientific approach of the Trace&Treat project which is funded by State Environmental Fund of the Czech republic. The aim of the project is to demonstrate the applicability of advanced oxidation processes based on ozonation in combination with nature-based sollutions (artificial wetlands, bioremediation filters, activated carbon filters) in order to remove selected types of pharmaceuticals and their metabolites from wastewater treatment plant effluents and from highly loaded point sources (e.g. . medical and veterinary facilities). The aim of the project is to realize a demonstration of the proposed technologies in selected locations with minimum of 80 % average removal rate of substances of the indicative list from wastewater

Removal of pharmaceuticals from a highly loaded source using ozonation

In recent years, the problem of the occurrence of micropollutants has attracted the attention of the professional and lay public, mainly because of the potential threats these substances pose to the environment. Efforts to regulate the occurrence of micropollutants in the environment are gradually being transformed into proposals for methodologies and guidelines aimed at monitoring and eliminating these substances. In the field of water management, a regulation is currently being prepared at the level of the European Union, which in its proposal calls for a significant reduction of selected representative micropollutants at wastewater treatment plants (WTP) by the end of 2035.

Ozonation technology using the principle of advanced oxidation processes was tested at the demonstration site of the Brno Veterinary University campus, representing a source highly loaded with pharmaceuticals. In total, seven experimental sets of measurements were carried out for the treatment of the effluent from the local WWTP, during which 24 different doses of ozone were tested. At an ozone dose in the range of 5.5 – 6.4 g O3/m3, an 80% reduction in the concentration of monitored pharmaceutical substances was achieved. Vibrio fischeri luminescence inhibition tests confirmed that the use of ozonation technology for the treatment of sewage effluent did not lead to a worsening of the ecotoxicological profile.
