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.

Cartridge filtration involves disposable filters, while 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 as an alternative to cartridges. The efficiency is limited to particles in excess of 1 microns.
