The equipment included in this forecast are gravity belt filters, belt filter presses, drum filters, leaf filters, granular media filters and bag filters. These devices are separating particles between 1-100 microns from various liquids from water to wine. Dewatering of sewage sludge and other slurries is a major use.

East Asia will dominate the market next year for several reasons. The first is the large investment in belt filter presses to dewater sewage sludge, mining ores and coal slurries. The large investment in flue gas desulfurization will be accompanied by significant investment in belt filters to dewater gypsum. Granular media filters will purify much of the water needed for cooling in coal-fired power plants.

Hardware sales in NAFTA will be less than 50 percent of the hardware sales in East Asia, but the sales of media will be more equal. This is because the existing market is large in NAFTA but the new expansions are comparatively few.

NAFTA will benefit from a substantial expansion of oil and gas processing plants. Hydraulic fracturing is creating the need for treatment of the flow-back liquid which contains sand, shale particles and high levels of dissolved solids.  Treatment of produced water is another expanding application.  The use of automatic backwash filters in treatment of ballast water is another growth segment.
