Garnet is used in the treatment of potable water, sewage and industrial effluents. It is installed as a layer beneath the sand or sand / pumice in dual or multi-media filtration systems. The filtration garnet is used to assist in filtering out fine particles which may not be retained by the sand and in dual filtration systems is usually supported on a layer of coarse support garnet.
