Abstract

A method for filtering a precipitatable constituent from an extraction solution through a filter apparatus includes pre-cooling at least a portion of the filter apparatus to a reduced temperature that is effective to precipitate the constituent from the extraction solution. At least the cooled portion of the filter apparatus may be thermally conductive to act as a heat sink for the extraction solution being passed through the filter apparatus. The reduced temperature facilitates removal of the precipitatable constituent from the extraction solution.
