The influence of operation conditions on the permeative flux of (PVC PS)‎ hollow fiber membrane

Abstract EN

Membranes 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 (10℃) to (30℃).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.
