Anthracite filter material is specially selected from deep mines with the highest carbon content. When combined with filter sand, anthracite is an excellent filter media for drinking water or industrial water purification. It is one of the most commonly used filter media.
It is a good addition to hybrid filters and is used in combination with sand or green manganese sand. Due to the special shape of its particles, it allows suspended particles to be retained deep in the filter bed. Compared to sand filters, this filter media allows higher flow rates, lower pressure drops, and better and faster backwashing.
Anthracite is extremely porous and has a large surface area, which can remove a wide range of impurities from water, including suspended particles, organic matter, and certain dissolved contaminants. Anthracite filter beds, which usually use sand or garnet, have a layered structure. This structure further enhances the ability to capture small and large particles.
There are many advantages to using anthracite to filter water, such as:
Anthracite is naturally hard and chemically stable, so the filter has a long service life. In addition, they do not easily degrade and do not need to be replaced frequently, making them an economical choice.
Anthracite is chemically inert and does not react with water or common water treatment chemicals. This inertness ensures that the filtration process remains stable and does not introduce additional contaminants or alter the chemistry of the treated water in any way.
