Filter Media – Anthracite (filtracite)
Supplied in 25 ltr bags
Filtracite is selected, naturally-hard, clean Welsh Anthracite, the finest in the world. It is an excellent filtration medium for gravity and pressure filters, for the treatment of hard and soft water, sewage, oil, acid/alkali liquids. The hardness of Filtracite ensures minimum wastage by attrition in service.
Filtracite is practically free from water-soluble constituents and mineral matter other than the low inherent ash content of the specially selected anthracite from which it is made. It contains over 90 per cent of pure carbon, and its low silica content is a decided advantage in the treatment of alkaline waters for boiler feed purposes.
The irregular shape of the particles offers a larger surface area per unit of volume and larger spaces between particles, which enable high filtration rates with low head losses to be obtained. The greater surface area of Filtracite promotes the efficient removal of algae, turbidity and bacteria. Filtracite’s low bulk density, coupled with the irregular and angular shape of a densely packed bed: thus the whole depth functions as a filter and not merely the top part, as with other closely-packing materials.
- Faster filtration
- Longer filter runs
- Low loss of head
- Economic use of space
- Long life
- Savings in wash water
- Big capital savings
- Easy to handle
- Available in several sizes
Filtracite is beneficial for rapid gravity and pressure plant, and for tackling oils, acids and alkalis. A prime benefit of anthracite and sand filter beds is that filtration in depth can be applied to existing as well as new filtration plant.
The main improvement resulting from dual media beds is the reduction in the rate of head loss build-up at a given filtration rate.
Thus, the length of filter runs can be up to three times that achieved with a conventional sand bed, or filtration rates can be increased while yielding acceptable lengths of run and, overall, the incorporation of anthracite and sand media can double nominal filtration capacity.
Filtration has been chosen for many installations by the Water Authorities in Britain and it is in steady demand from leading chemical companies. Filtracite is exported all over the world.
