We hope that such mistakes will be avoided. However, we emphasize
that both of these brine streams would be deemed injectible under the
criteria presently in vogue: they would be able to pass freely through
a micron-sized membrane filter and would not cause visible fouling of
metal surfaces during field tests of a few days duration. It is precisely
the refinement of such criteria that we hope to have accomplished with the
work summarized here.

Energy of the U. S. Department of Energy.
