Contamination and Removal Efficiency of Microplastics and Synthetic Fibres in a Conventional Drinking Water Treatment Plant

Microplastics have been detected all around the globe in freshwaters which are frequently used to produce drinking water. Therefore, contamination of raw water with microplastics that supplies treatment plants, and their removal efficiency is raising more concern interest. In present study, we evaluated microplastic a conventional plant (Geneva, Switzerland) contribution coagulation on filtration systems (sand activated carbon filtrations) (MPs) synthetic fibres. This work was performed pilot station replicates main process. Raw effluents each filtering processes were analysed for presence MPs fibres sizes ≥ 63 μm using infrared spectroscopy. The ranged from 19.5 143.5 MPs/m 3 0 8 (in absence coagulant), respectively. On other hand, concentration 7.7 23.8 fibres/m Results show average 89% 81% (≥63 μm) retained coagulant. Better final (97%) (96%) observed treatment. chemical composition found heterogeneous than after sand filtration.
