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
- NSF Certified in accordance with ANSI/NSF Standard 61, Drinking Water System Components
