Abstract
An improved inclusive method for purifying a polar solvent such as water includes the re-suspension of finely divided layered materials within which contaminants have been captured, wherein the re-suspension is in a solvent selected primarily on the basis of its ability to re-suspend the finely divided layered materials and/or for its effect on the included contaminant material, and within which additional materials may or may not be intentionally dissolved, mixed, or suspended, in order to recover and reuse the finely divided layered material and/or to selectively recover a specific included contaminant or several specific included contaminants in series. The process is useful in the rapid and efficient recovery of the finely divided layered materials, and in the removal of suspended particles, dissolved materials, immiscible liquids, and living organisms from the polar solvent.
