I mainly work with the development of a Python toolbox for analysis of high sampling frequency data of optical sensors (absorbance and fluorescence) in drinking water treatment. The aim is to quantify and characterize natural organic matter (NOM). High concentration of NOM can affect the taste and odor of the produced water, growth of bacteria, viruses and parasites, as well as the formation of carcinogenic disinfection byproducts (DBPs). The project also aims at a deeper characterisation of NOM fractions from surface water to processed water, using mass spectrometry techniques in relation with organic micropollutants and pharmaceuticals.
