AbstractMembranes have gained an important place in chemical technology and are used
in a wide range of applications. This investigation has studied the effect of operating
conditions such as temperature, trans-membrane pressure and solute concentration
on the separation performance of (PVC/ PS) hollow fiber membrane, which was
prepared in the laboratory from 15% (PVC) and 2% (PS) using phase inversion
method. An attempt was done to investigate the ability of PVC/PS hollow fiber
membrane for ultrafiltration application. A (PVP) solute was used to measure (PVP)
rejection of prepared membrane.
The predicted flux was found to increase from (18.88 l/m2.hr) to 33.05 l/m2.hr)
when the operation temperature was increased from (10Ž) to (30Ž).While it
increased from (28.57 l/m2.hr) to (263.36 l/m2.hr) when the operation pressure was
increased from (1bar) to (3bar). It was also found to decrease from(17.97 l/m2.hr) to
(12.20 l/m2.hr) with increase solute concentration from (1000ppm) to (2500ppm).
The rejection efficiency was equal to (99.93%) when using (2500ppm) solute. This
is considered within UF range.
