Abstract : Research effort was concentrated upon building two heavy-duty membrane presses, securing adequate bulk samples of natural clays, and reviewing literature. The principal portion of the contract effort reported here is contained in two completed Ph.D. theses, by William M. Benzel and Paul R. Haydon, and one that is nearing completion, by Ilham Demir. These theses consider the effect upon clay-membrane transport at 20 C of the thickness and fabric of the clay cake, the effect of temperature in the range 20-180 C upon membrane transport and membrane fractionation of the stable oxygen isotopes contained in water molecules, and the electrokinetic behavior of these clay membranes at 20 C. It becomes possible after completion of these many months of experimental runs to evaluate the difficulties encountered with experimental apparatus.
