In addition, a preliminary migration test of the different materials used in the DWTP has been performed to identify potential sources of microplastics in each treatment step.ĩ8/83/EC (1998) Council Directive 98/83/EC of 3 November 1998 on the quality of water intended for human consumption. Furthermore, the results showed that ultrafiltration/reverse osmosis (advanced treatment) is more effective for microplastic removal than ozonation/carbon filtration stage (upgraded conventional treatment). Sand filtration was identified as the key stage in microplastic removal (78 ± 9%). In the intake of the DWTP, the mean concentration was 0.96 ± 0.46 microplastics/L ( n=5), with a predominance of polyester (PES) and polypropylene (PP) and at the outlet the mean concentration was of 0.06 ± 0.04 microplastics/L with an overall removal efficiency of 93 ± 5%. Microplastics were detected in 5 out of 7 points along the Llobregat basin, with concentrations ranging between non-detected and 3.60 microplastics/L. Identification of microplastics of size range from 20 μm to 5 mm was performed by fourier-transform infrared spectroscopy (FTIR). Due to different water composition, different sampling and sample preparation protocols were used to determine microplastics from river water and in the DWTP. ![]() ![]() This paper has examined the presence of microplastics along the Llobregat river basin (Catalonia, Spain) and studied their behaviour and elimination along the drinking water treatment plant (DWTP). Nowadays, the presence of microplastics in drinking water is of concern worldwide due to potential impacts on human health. ![]()
