Transient modeling and experimental verification of hyperfiltration effects
"Previous investigators have demonstrated in a number of laboratory studies that clays and shales exhibit membrane properties. One membrane process thought to occur in the subsurface is hyperfiltration. Hyperfiltration, also called reverse osmosis, occurs when hydraulic head acts against the osmotic gradient reversing the direction of water flux. However, prediction of hyperfiltration in subsurface materials and relations to clay-rich engineered barriers has been problematic. Therefore, the goal of this research was to develop a transient model capable of describing hyperfiltration effects in natural, membrane-functioning materials. To that end, a set of analytical equations describing transient hyperfiltration was developed and a computer program was written in VISUAL BASIC to implement the transient hyperfiltration model"--Abstract, leaf iii.
