|Typical chemical analysis|
A natural alluvial Almandite garnet
300 600 micron. A maximum of 5% of the product is coarser than 600 microns and a maximum of 5% of the product is finer than 300 microns.
Method of use
This type of garnet is usually employed as a layer beneath B.S. 16/30 sand in multi-media filters in order to provide a means of filtering out fine particles which may pass the sand bed. Because of the relative densities of the garnet and sand, the garnet layer will re-form below the sand on settlement after backwashing. It is generally necessary to support the filtration garnet on a layer of support garnet.
Filtration garnet is available in 25kg or 50kg. Multi-wall paper sacks palletised and shrink wrapped and also in bulk bags.
Safety data sheet
Description: Shiny red to red-brown granular solid in various size gradings.
Manufacturers intended use: As a filtration or support medium in water treatment for use in multi-media rapid gravity and pressure filters.
Composition: A naturally-occurring iron aluminium or iron calcium silicate.
Fire hazard: No fire or explosion hazards.
Health hazards: Inhalation of dust may cause irritation of respiratory tract. Irritation may be caused if particles enter the eye.
Precautions: Exposure to garnet dust should be kept as low as reasonably possible. This may be achieved by the application of appropriate industrial hygiene methods and the use of appropriate personal protective equipment. Such equipment would include respiratory protective equipment of a type approved by the Health and Safety Executive and eye protection.
Spillage: In the event of spillage, avoid breathing dust. Wear appropriate respiratory and eye protection and sweep up.
Disposal: Any spilt or surplus garnet may be disposed of by an approved solid waste disposal method.
Eyes: Flush with copious quantities of water Skin: Wash with soap and water Ingestion: Non-toxic
