Midland, Mich.-based Dow Chemical Co. manufactures DOWEX ion exchange resins that are typically used for applications like water purification. Ion exchange resins can also be applied to separate and purify disease fighting, therapeutic agents from impurities during the drug manufacturing process. This is important because many drugs are present in very small concentrations with other chemicals and must be separated and concentrated to be useful.
