Exploring Alternative Media for Multimedia Filtration: Beyond Sand

An alternative to using anthracite, sand or garnet is AFM, (Activated Filter Media). I have reviewed this technology on a number of occasions and have had colleagues who have enjoyed excellent results since it is resistant to bacterial growth.

Activated Filter Media (AFM) is a type of filtration media used in water treatment systems. AFM is a porous, glass-based material that is treated with an activating process to create a high surface area for the adsorption of contaminants from water. This makes AFM an effective tool for removing a wide range of contaminants, including heavy metals, organic matter, and other pollutants.

AFM is commonly used as a pre-treatment step in reverse osmosis (RO) systems, where it helps to reduce the levels of total dissolved solids (TDS) and other contaminants in the feed water. This helps to protect the RO membranes from fouling and damage, and improves the overall performance and efficiency of the RO system.

AFM is often preferred over traditional activated carbon filtration media because it is more effective in removing a wider range of contaminants and has a longer service life. Additionally, AFM is less likely to release contaminants back into the water, and it is more resistant to bacterial growth.

Generally, AFM is a highly effective filtration media for water treatment, offering a range of benefits for removing contaminants and improving RO and other water treatment systems.
