Garnet sand is used as a support layer in a multi-media filtration system. Garnet is a naturally occurring gem mineral. It has a uniform chemical, physical, hardness, friability, and micro-structure characteristics. These uniform characteristics provide the essential properties for water and industrial chemical processes. Garnet can be used for a range of applications, from small, single-media filters to technically-advanced multimedia commercial and industrial systems. Garnet media removes turbidity from water by reducing the amount of suspended particles. The media makes the water drinkable. The bag weighs 50 lb.
