Studies in the literature [15–19] indicate that distinct methods have been applied for glycerol removal and biodiesel purification.Among the alternative methods of separation,the process with membranes has many advantages and good prospects for use in the separation and purification of biodiesel.The use of membranes can provide high quality and purity biodiesel,and environmental and economic advantages for reducing the amount of water used and eliminating the use of adsorbents.A part from the reduction of costs related to effluent treatment,studies indicate that the use of membranes in the processing of biodiesel provides reduced power consumption,enabling the application of this process in industrial
