Effect of SDS Concentration on the Thermal Property and Performance of Low Pressure Active Reverse Osmosis (LP-ARO) Membrane for Brackish and Seawater Desalination

摘要

This study reported the preparation of newly low pressure active reverse osmosis (LP-ARO) membrane by phase inversion technique. The effect of different concentration of Sodium Dodecyl Sulphate (SDS) surfactant on thermal property and performance of LP-ARO membrane were determined. Using brackish and seawater as samples, the membrane performance was evaluated in terms of PWP, flux and salt rejection. Experimental data revealed that 2.0 wt. % of SDS was found to be the optimum concentration for the production of LP-ARO membrane with good thermal property and high performance of brackish and seawater desalination.
