Granular Media Filter Sales to Exceed $2.4 Billion in 2021

Granular media filters will account for 29 percent of the world liquid macrofiltration market in 2021.  This is the latest forecast in N006 Liquid Filtration and Media World Markets published by the McIlvaine Company.


Granular media filter functions can be divided into particulate and dissolved segments.  The market for particulate removal in drinking water plants will expand slower than the total market due to market share loss to cross-flow membranes. On the other hand, the market for removing dissolved contaminants is booming.

Perfluorinated compounds, or PFCs, are manmade, fully fluorinated compounds that are not naturally found in the environment and are used in a range of products such as fire-fighting foams and coating additives. PFOS and PFOA are the most commonly produced PFCs.

PFOA and PFOS are persistent and itinerant in the atmosphere and aqueous environments due to their high chemical stability and low volatility. In their anionic form, PFCs are water soluble and can easily travel from soil to groundwater, carrying the contaminants long distances. Toxicological reports indicate potential developmental, reproductive and systemic effects after oral exposure, as PFCs accumulate and absorb in the serum, kidney and liver. Because PFCs are resistant to direct oxidation, photolytic degradation, biodegradation and air stripping/vapor extraction, their removal is very difficult.

AdEdge,  Cabot, Calgon Carbon, Carbon Activated Corp. , CEI Carbon, Evoqua, Jacobi Carbon, Ovivo, Oxbow and VAF filters are offering PFC removal solutions.  Calgon Carbon demonstrated that granular activated carbon (GAC) is an effective way to remove PFCs from sources of drinking water.  GAC is successful in removal of harmful compounds in groundwater, including PFOA as well as perfluorobutanoic acid (PFBA), perfluoropentanoic acid (PFOA), perfluorohexanoic acid (PFHxA) and perfluorodecanoic acid (PFDA). The spent activated carbon, containing adsorbed PFCs, can be thermally reactivated, thereby destroying the contaminants and allowing the activated carbon to be recycled and reused in groundwater treatment applications. Lab testing and field trials have led to activated carbon systems being successfully employed to treat groundwater for PFC removal throughout North America.
