Properties of the tested NF membranes (information provided by the supplier and/or extracted from the literature).

Membrane	Charged Groups	Membrane Effective Area (m${}^2$)	Pure Water Flux (LMH/bar)	MWCO (Da) *
NF270	COO${}^{-}$	0.0042	16.10 [17]	226 [17]
NF90	COO${}^{-}$	0.0042	7.69 [17]	118 [17]
HFNF	SO${}_3^{-}$	0.1750	5.00	200–300
	SO${}_3^{-}$	0.1710	0.64	100–200

* The reported Molecular weight cut-off (MWCO) is an estimation as it depends on the test conditions as well as charge, polarity, size and shape of the compound.
