ABSTRACT:
The present invention relates to the treatment of particular filteraids to reduce the beverage soluble iron. In the method of the invention, a particulate filteraid, such as diatomite, is contacted with an aqueous solution of particular chelating agents. The process is applicable to treatment of loose filter media and is also applicable to the treatment of filter media in filter sheets. Lowering the pH during the time that the filter media is being contacted by the chelating agent produces an optimum affect.
