Galaxy - High Density Garnet for Water Filtration

Opta Minerals your source for Water Filtration Media:

Galaxy Garnet is a naturally hard and HIGH DENSITY filter material used in multi–media water filtration systems. Garnet is recommended as a support bed for other materials such as sand, anthracite etc.

Galaxy Garnet is carefully screened to appropriate sizes for water filtration.

Galaxy Garnet is a hard rock garnet and is mined from an Almandite Garnet deposit with proven reserves of over 1 million tons.
Galaxy Garnet is processed from crude by means of crushing, milling, washing, drying and screening.
Galaxy Garnet is carefully screened to appropriate sizes for water filtration.

Advantages of Galaxy Garnet for Water Filtration

High specific gravity allows unique filter designs. In combination with other filter media both higher flow rates, higher loadings and better filtration can be achieved.
High Hardness reduces attrition and provides for years of reliable service
