Anthracite Filter Media Testing Services
Pennoni provides ongoing testing of filter media in accordance with standard AWWA and or ASTM test methods for various materials used in municipal water filtration systems. Multimedia filtration systems comprise mainly of three materials: anthracite, and, and granite or ilmenite as illustrated below. The design concept of the multimedia filter placed the coarse aggregate at the top and the fine aggregate at the bottom. The large particle or solids are trapped in the anthracite, the sand removes solids that penetrate that layer, and the garnet removes the remaining material.
