ANTHRACITE

Description

Anthracite is a type of coal, and is the coal with the highest carbon content, in excess of 95% by weight. Like most minerals, anthracite formed over millions of years of deposited plant layers, combined with pressure and temperature.

Of all the carbon materials, this black and rather shiny mineral is the hardest of them all. Long used in water filtration applications, the anthracite used for water filtration is usually specially selected from deeper mines. Due to higher pressures, the carbon content is typically even greater.

In simple terms, filter media are materials that facilitate the passing of raw untreated water through them. While retaining any impure particle matter, allowing now cleaner water to pass through. Each filter medium has specific characteristics such as size, weight, whether they are activated or non activated, gravity and more. All of these characteristics give rise to differing operational performance at certain filtration tasks. Oftentimes a compromise between them is sought to provide the most robust system, or a system at a lower price point. Anthracite’s broad tolerance of contaminants and ease of forming it into a filtration grade product make it a popular choice.

For drinking water, wastewater filtration and water for industrial use, anthracite has ideal properties for purifying this type of water. Especially when utilized in combination with other sand filters, or as a component of a dual- or multi-media filtration system.

Because of its ideal properties, relative ubiquity and ease of use, anthracite as a water filter medium is one of the most widely used around the world.
