Abstract
A filter media for implementation in a sugar purification process that allows for a significant increase in sorbent material while maintaining, and enhancing the decolorization and. hydraulic properties. The filter media incorporates sorbent material, fiber having specific properties that allows for small particle sorbent material without jeopardizing the hydraulic properties of the media, and an electrolyte. The sorbent material is an inorganic, an adsorption, or ion exchange media, or a metal-organic framework. The implementation of this filter media in a sugar purification process eliminates the need for a clarification step during refining while providing for enhanced decolorization and hydraulic properties for fluid flow.
