You know about this, do you? http://journeytoforever.org/biodiesel_glycsep.html Separating glycerine/FFAs >To all the members of the groop : >I am very happy to have found you. >I thought I was the only freak on environment and so, but now with all you I >really feel like I have found very good company. >Keep going!
