Column experiments.
Adaptation of the particle suspension to sites
Further development of nano- and microparticles for the aquifer remediation
State of the art particle and pollutant analysis
In our laboratory in Leipzig, a dedicated team of chemists, biologists, soil scientists, and geologists works to further develop our nano- and microparticles. In this way, we are able to improve and adapt them to sites on a customised basis.
Within the scope of national and international research projects, we are also constantly developing new materials to fight pollutants for which a solution has not yet been found. To this end, we work together with leading developers in this field and publish in the most prestigious journals.
With nanoparticles, we create an immobilized reactive zone through which the contaminated aquifer flows. This is the principle we know from permeable reactive barriers, but without the need for excavation work.
