Abstract: The invention relates to a process of coating inorganic particles with organic compositions, and agglomerating, compacting and heating of the coated particles into granules. Coating and compacting the agglomeration may be conducted continuously, and may be used to form granules having sizes ranging from about 1 to about 200 mesh. In one embodiment, these particles can be used to purify drinking water by removing heavy metals such as arsenic, lead and mercury and to remove or kill microorganisms in the drinking water, air and gas.

Abstract: The invention relates to methods and compositions for removing contaminants from edible cooking oils. Reduction in the accumulation of contaminants such as polar materials, free fatty acids, metals, color bodies, and soaps is achieved by treating the oil with a composition containing effective amounts of silica, acidic alumina, clay and citric acid. Removal of contaminants from oil according to the methods and compositions of the invention improves the quality of the oil and reduces costs as well as various health and safety concerns associated with the production of fried foods.
