Filter media are substances that let raw water pass through them while capturing the impurities. Based on desirable physical properties, such as specific size, gravity, and particle sizes, filter media are chosen.
We offer high-quality filtering media in Netsol Water that is appropriate for use in all wastewater treatment, and water purification applications. Additionally, we uphold exclusivity contracts with producers all around the world, which enables us to offer a product of unrivalled quality at a very affordable price.
We will discuss about the use of anthracite as a filtering medium in the treatment, and purification of water.
Anthracite
It is a mineral coal with a high degree of hardness and carbon content. Like all mineral coals, it is created by the gradual (millions of years) transformation of plant matter, under the influence of pressure and temperature. It is the last one on the Cobonus scale and the one that requires more heat and pressure to create. It is the most dense and hard of the carbons, is black and lustrous, and contains a significant amount of carbon (more than 95%).
When combined with filtering sands, anthracite makes an effective filter media for drinking, or industrial water purification. With sand or green manganese sand, it makes a wonderful addition to mixed filters.
It enables the retention of the suspended particles at the depth of the filtering bed, due to the unique grain shape of its grains. This filtering media permits a higher flow, less pressure drop, and a better and faster backwash as compared to a sand filter. Materials for anthracite filters are deliberately chosen from deep mines, with the maximum carbon content.
Multilayer beds for filtration
A common method for removing suspended particles from raw water is filtration, using multilayer beds. This method is mostly utilized in the treatment of drinking water, desalination, and wastewater.
How to utilize anthracite in the filtration and treatment of water?
One filter bed or numerous overlapping ones may be used for filtering. The less dense filtering medium, such as anthracite, are typically placed on the upper half of multilayer beds, to give the impression that the solids are held there.
Following the first layer of the finest material, like sand, are layers of coarser sand, fine gravel, and finally a thick layer of gravel, acting as a support. Because, of its better ability to hold particulates, anthracite is distinguished by consistently improving turbidity extraction.
With the help of our expert team at Netsol Water, we are able to provide filter media and anthracite of the highest calibre, at a price that is quite competitive.
