C&S Brand Australian Garnet Gravel
About C&S Brand Australian Garnet Gravel
C&S Brand garnet filter gravel is a hard rock garnet and is mined from an almandite garnet deposit. Colour is pinkish to red-brown and it has an ideal hardness, durability and abrasion resistance. It is well-proven for use as a filtration medium in granular media filters, including support gravel layers in multi-media systems.
C&S Brand garnet filter gravel provides uniform physical and chemical characteristics. It has a high specific gravity, meaning it is more stable during backwashing, retaining the integrity of the filter bed. C&S Brand garnet filter gravel allows for a shallower support layer compared to silica gravel which results in savings on filter construction costs as it has been proven to require less filter depth than silica gravel. Moreover, garnet gravel better prevents downward migration of filter sand and consequent fouling of underdrains.
