ABSTRACT:
A method for separating dissolved materials, including organic and inorganic solids and volatile constituents, from a liquid or aqueous solvent is disclosed. The method first extracts water from the flow stream being treated using a crystallization apparatus which freezes the water onto a continuous loop wire rope and withdraws the wire rope from the chamber containing the feed stream. The resultant concentrated solution is then subjected to a different process of evaporation by heating at reduced pressures resulting in the efficient separation of the materials in solution from the liquid medium while conserving energy. This procedure is considered highly effective in allowing for the concentration of the materials and then the extraction of the materials in solution and the recycling and reuse of the water or other liquid.
