There fore, there is a need forad ditional membrane treatment stage
in order to purify the composite permeate for the purpose of reuse.
In the second step,the experiments were conducted with FMNP030
membrane at pH 10,25 ◦C and VRF5 for different transmembrane
pressures (12,20,28 and 36 bar)to provide better permeatequality like actual process water. The permeate fluxes with respect to
VRF values for composite permeateat different transmembrane
pressures are presented in Fig. 7.
