Decoloring Methyl Orange under Sunlight by a Photocatalytic Membrane Reactor Based on ZnO Nanoparticles and Polypropylene Macroporous Membrane

Table 1

Relative water flux (%) through PHEMA grafted and ZnO NPs immobilized PPMMs with different GD. The average water flux for the membranes is 400 ± 25 Lm⁻² h⁻¹.

GD, % (wt)	Water contact angle on PHEMA grafted PPMMs,°	Relative water flux, %
