The chemical industry will spend $688 million for cartridges to remove particles from liquids next year.

Three regions, East Asia, Western Europe and NAFTA will account for most of the market. Included in the forecast are all non-cleanable cartridges used to remove particles from the water intake, plant process fluids and wastewater. It also includes cartridges used to purify the cooling tower bypass.

The forecasts do not include cartridges to remove particles or liquid droplets from air. They do not include cartridges used to purify hydraulic or lubricating fluids. Also excluded are automatic backwash filters which are self cleaning. Cross-flow membrane modules are not included in this report, but in a separate McIlvaine report (RO/UF/MF). Media includes non-wovens, membranes, stringwound, ceramic, carbon block and metal.

The market to replace existing cartridges accounts for most of the revenues. This is because cartridges are replaced very frequently. In extreme cases, cartridges can be replaced several times per day. There are very few cartridge applications where the life can be measured in years.
