Filter media is a type of material used in water treatment systems to remove impurities from water. There are various types of filter media available in the market, each designed to target specific contaminants in the water.
Some of the commonly used filter media in water treatment are sand, gravel, activated carbon, anthracite, and zeolite. Sand and gravel are used in the initial stages of filtration, as they can trap large particles and debris from the water. Activated carbon is often used to remove organic compounds, chlorine, and other harmful chemicals from the water. Anthracite is another type of filter media that is commonly used in the final stages of filtration to remove any remaining impurities.
Zeolite is a mineral-based filter media that is highly effective in removing heavy metals such as lead and arsenic from water. It also has ion exchange capabilities that can remove calcium and magnesium ions, which can cause hard water.
The selection of filter media depends on the water quality, the type of contaminants present, and the required treatment level. The right combination of filter media can effectively remove most of the impurities from the water and make it safe for consumption.
Filter media is available in different forms such as granular, powdered, and extruded pellets. The choice of form also depends on the type of filtration system and the required treatment level.
