Title

Prediction of ultrafiltration membrane performance based on viscosity of polymer solutions

Pages

  25-34

Abstract

 One of the most important factors affecting membrane formation via phase inversion method is the Viscosity of the polymer solution. In this research, with the aim of providing a solution to predict the performance of polymeric membranes based on Viscosity data, the influence of dope solution temperature and casting speed on the Viscosity of PVDF solution were investigated. For this purpose, the Viscosity of PVDF/DMAc solution with LiCl and PEG additives was measured at the temperature range of 10-50 ° C and atmospheric pressure with a precise rheometer. The performance of PVDF Ultrafiltration membrane with composition of PEG 3 wt. % and LiCl 7 wt. % was evaluated and an empirical model using response surface methodology and central composite design was developed to predict membrane permeability and rejection based on Viscosity data and two variables of solution temperature and casting speed. Scanning electron microscopy, pure water permeability, and membrane rejection tests were used to characterize the membranes. The results show that the model is in good agreement with the experimental data and based on the results, the casting speed of 1. 2 m/min and the temperature of the polymer solution at 50 ° C are the optimum conditions for membrane fabrication to obtain the membrane with maximum flux and rejection.
