Abstract: A treatment solution and method for removing heavy metal contaminants and oxyanion contaminants from an aqueous solution by promoting the affinity of precipitating the contaminants. The method adjusts the pH and the ORP of the contaminated aqueous solution by applying FeCl2 and/or NaOH reducing agents, and using and applying a titania-based treatment solution of TiO(SO4), H2SO4, and FeSO4.

Abstract: An alumina-based adsorbent and method of making exhibiting high affinity and capacity towards fluoride ions and oxyanions of phosphorus and arsenic in a broad pH range and presence of large excess of competitive ions. Alumina based adsorbent is a mixed oxide of alumina existing in tetra-, penta-, and octahedral coordination at specific ratio, and oxides of polyvalent metals of elements titanium, zirconium, tin, cerium, lanthanum, iron, or combinations thereof. The alumina based adsorbent may be used for selective removal of fluoride ion and oxyanions of phosphorus and arsenic from drinking water, industrial streams and wastes, in medicine and food industry.

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.
