Content DescriptionThis standard covers diatomaceous earth (DE), perlite, and other disposable filter materials used to precoat filters for water supply service application. The purpose of this standard is to provide a guide for evaluating precoat filtration media. The criteria should be used to determine if such media is similar to the product currently being used to produce potable water in a specific water treatment plant or pilot project. Extensive use of DE and perlite by the water industry supports the need for this standard. Major revisions to this version of the standard include Revised Permeability Test Procedures Added Sample Permeability Calculations
