From: Advanced nanobubble flotation for enhanced removal of sub-10 µm microplastics from wastewater
a Identification of hydroxyl radicals using the APF method; b In situ methylene blue degradation during NB generation; c Comparison of TOC removal by MB-F and MNB-F at coagulant dosages of 5, 10, 25 ppm (independent t-test, p < 0.05). d The removal of turbidity and TOC from the real wastewater by the two flotation processes at an AlCl3 dosage of 10 ppm. Data points and error bars in c and d represent the mean and standard deviation of three independent measurements each from two independent experiments.
