Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (, in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.
