Rejection of Organic Micropollutants by Clean and Fouled Nanofiltration Membranes

Table 5

Influence of transmembrane pressure on dimethyl phthalate rejection and permeate flux (the feed solution contained 800 mg L⁻¹ dimethyl phthalate; pH 7.5, 10 mM NaCl).

Transmembrane pressure (kPa)	NF90		NF270
	Flux (L m^−2 h^−1)	Rejection (%)	Flux (L m^−2 h^−1)	Rejection (%)
500	43.4	95.8	65.2	65.8
600	57.2	95.0	88.5	17.9
700	66.5	92.5	108	14.0
