Removal Efficiency of micro- and nanoplastics during the treatment of CFS and CFS with PolyDADMAC

Treatment	Removal Efficiency					p-value (ANOVA)
	180 nm	1 μm	10–20 μm	45–53 μm	106–125 μm
CFS	Not observeda	< 0.1 %	1.8 % ± 1.2 %	0.3 % ± 0.3 %b	1.4 % ± 1.2 %	0.5
CFS + PolyDADMAC	Not observeda	< 0.1 %	1.0 % ± 0.2 %	13.6 % ± 6.8 %b	2.1 % ± 0.6 %	0.001

^a“Not observed” indicates that no spiked fluorescent particles were observed in the sediment. The filter membranes capturing spiked fluorescent particles in the sediment were completely black. The entire membrane was scanned for any sign of fluorescence and determined not to contain any spiked fluorescent particles.

^bA significant difference in removal efficiency was observed between the treatment of CFS and CFS with PolyDADMAC (p = 0.04) for 45–53 μm of particles.
