Abstract
Provided are methods of modifying solid particles with functional agents to provide anti-microbial media. The anti-microbial media comprise a surface-modified inorganic component which is a reaction product of an anti-microbial component and an inorganic component. Methods of making the media include agitating inorganic base material in a processing tank substantially simultaneously with spraying the anti-microbial component into the processing tank to form a coated base material. Methods of making the media also include maintaining a ratio of the anti-microbial component to the inorganic component such that the coated base material is below its compaction point. Methods of use are also provided.
