The growth will be fueled by Asian demand. By 2017, well over 50 percent of the sales will be for use in China and other Asian countries. Macrofilters are widely used by municipal water treatment plants, municipal sewage treatment operators, power generators, steel mills, chemical plants and pulp mills. There is much more construction of these facilities in Asia than on other continents.

Macrofiltration needs to be distinguished from cartridge filtration and from cross-flow filtration. McIlvaine has a separate cartridge report and another on reverse osmosis and other cross-flow membranes. Cartridge filtration involves disposable filters. Cross-flow filtration utilizes membranes, but is distinguished primarily by the fact that only a portion of the incoming liquid is filtered and the balance moves across the filtration surface and remains unfiltered.

Macrofiltration includes those filters not part of the other two categories. Gravity media filters, filter presses, automatic backwash filters, belt filter presses and bag filters are all included in the macrofiltration category. The filter presses, gravity belt filters and bag filters can be used to separate products from liquids and are, therefore, used in food and chemical processing.

Belt filter presses are widely used to dewater sewage sludge. Gravity belt filters are typically used to separate gypsum in flue gas desulfurization systems. Gravity media filters including those with sand and synthetic media are used in water treatment. Automatic backwash filters are increasingly used an alternative to cartridges. The efficiency is limited to particles in excess of 1 microns. The advantage is the fact that the units are self cleaning.
