Abstract
An improved process for clarifying sugar syrup in the flotation system of a sugar making operation. Neutral phosphate-based compounds are added to the flotation system to aid in clarifying the sugar syrup. The use of the neutral phosphate-based compounds will eliminate the use of phosphoric acid and the commensurate need for neutralizing chemical as well as elimination of the tanks for phosphoric acid and neutralizing chemical mixing at field installations.
