EP Minerals' PurifiDE® XG Purified Siliceous Earth USP-NF filter aids are designed for use with pressure filtration systems, to separate solids from aqueous or organic liquids --in situations where leachable impurities from standard food-grade diatomite could negatively impact the filtrate. The use of PurifiDE® XG Purified Siliceous Earth USP-NF filter aids ensures that such impurities do not contaminate and alter, or reduce the shelf-life of high-value products. Applications include filtration of active pharmaceutical ingredients (APIs), labile chemicals, delicate nutraceuticals, easily oxidized oils, and vitamins, and luxury grades of bourbons, whiskeys, and sakes.
PurifiDE® XG, Purified Siliceous Earth USP-NF filter aids are made entirely in the USA using unique diatomaceous earth (DE) ores and proprietary purification processes. The resulting filter aids are superior to food-grade (FCC) DE filter aids in filtration performance, purity, usage rate, lot-to-lot consistency, and provision of regulatory support.
