As seen from Table 8, applied different transmembrane pressures did not cause significant changes on the flux declines and the
contact angle values for FMNP030 membrane. Flux decline analysis
revealed that concentration polarization was the larger contribution to the total flux decline for all transmembrane pressures. Flux
decline due to the fouling was the average of 11%,which indicates
that fouling was not very severe. Also,the contact angles of clean
and fouled membranes are almost same.The possible reasons for
the low increase in contact angles were thought to be either the
lower flux decline caused by fouling or membrane pore plugging
