| Abstract: | The treatment of Cr 3 aqueous solution by vacuum membrane distillation technique with laboratory and commercial strengthened microporous ploy (vinylidene fluoride) membranes were investigated under various operating conditions.The results suggested that the two kinds of membranes had flux values approximate to one another.The solute rejections of commercial membranes were higher than 90%.The effect of membrane parameters and operating conditions on the flux and solute rejection of membreanes had been discussed. |
