On 4 June 2024, 14:00 – 15:30 (CEST), H2Oforall and SafeCREW hosted their third joint webinar on disinfection. The webinar attracted mor than 100 attendees. The webinar focussed on Natural Organic Matter (NOM) as “Precursors of disinfection by-products“. The guest speaker Jean-Philippe Croue, professor in Environmental Engineering at Université de Poitiers, introduced DBP precursors, their origin, their structural characteristics and their reactivity. Scientists from the SafeCREW and the H2OforAll team presented two novel approaches for DBP precursor removal.
