Data underlying the publication_Evaluating the efficiency of enhanced coagulation for nanoplastics removal using flow cytometry

The aim of this study was to investigate the removal of nanoplastics from tap water using an enhanced coagulation approach and to evaluate the process efficiency with fluorescence-based flow cytometry (FCM). Fluorescently labelled polystyrene beads (PS-OSO₃⁻) of varying sizes were used to assess the impact of particle size on removal efficiency under different coagulant (Fe³⁺) doses. In addition to fluorescence-based analysis, turbidity measurements—widely used as a standard for water quality and recently adopted for nanoplastics removal—were conducted and compared with FCM. Enhanced coagulation was achieved by optimizing mixing conditions, specifically by varying the slow mixing speed at 100, 50, and 25 revolutions per minute (rpm).
