ABSTRACT:
A concentrator for reducing the volume of a mixture containing a solvent and various dissolved and/or undissolved solids includes a chamber adapted to receive the mixture and a heater coupled to the chamber for applying heat to the mixture within the chamber, the heat being provided at a temperature sufficient to vaporize the solvent. A condensing tower receives the vapors from the chamber and including a first stage and at least one second stage. A plurality of walls included in each of the first stage and the second stage of the tower direct the vapors along a torturous path including at least one reversal of direction in each of the stages. A coolant is provided to cool the second stage of the tower but not the first stage in order to facilitate condensation of the vapors in the second stage but not in the first stage of the tower. The coolant may include water in order to facilitate the processing of aqueous solutions.
