Highlights• Organic micropollutant (OMP) desorption batch tests with 3 activated carbons (AC) • Low (lmw) and high molecular weight (hmw) DOM fractions used as background matrix • Effects on OMP desorption extent are similar for lmw-and hmw-DOM fraction • Macroporous AC shows enhanced desorption of OMP, independent of DOM composition • Microporous AC shows irreversible OMP adsorption, independent of DOM composition

Increasing sulphate concentrations in some German drinking water resources require water suppliers to evaluate the applicability of state-of-the-art water treatment technologies for sulphate removal. In this study the carbon dioxide...
