Benzel, William Marc 2014-12-16T06:06:36Z 2014-12-16T06:06:36Z 10000-01-01 1982 1982 A solution 0.79 Molal in NaCl and 0.079 Molal in CaCl(,2) was forced through clay cakes made by sedimenting the one-half to two micron size fraction of Cheto clay. The two cakes sedimented from distilled water had nearly parallel-flake fabric whereas the two sedimented from the described brine approached random fabric. Clay cake thicknesses ranged from 0.5 to 2 centimeters, confining pressure was 5000 pounds per square inch, mean brine pressure was 2300 pounds per square inch, and the differential fluid pressure across the clay cake was 1000 pounds per square inch for random fabrics, 2000 pounds per square inch for parallel-flake fabrics. Steady state was achieved in 4 to 5 months. Salt filtration efficiency was roughly twice as great for parallel-flake cakes as those for random fabric. Calcium was preferentially transported over sodium across the clay cake in three of the runs, but this preference reversed for one run. Clay layer thickness was observed to have nominal effect upon salt filtration efficiency. Made available in DSpace on 2014-12-16T06:06:36Z (GMT).
