This forecast does not include reverse osmosis, microfiltration and ultrafiltration which remove smaller particles.  It does not include screens which remove very large particles. It covers the removal of particles from 1-50 microns. It does not include cartridges which are used for liquids with very low solids content.  It does include gravity media filters, automatic backwash filters, filter presses, gravity belt filters, drum filters, belt filter presses and bag filters. The bag filters are the only segment which is not self cleaning.

Large numbers of belt filter presses are being sold to dewater sludge in Asian municipal wastewater treatment plants. Gravity media filters are widely used to purify water as it is extracted from rivers and streams. Filter presses find many uses in the chemical industry where they are used to separate products. Drum filters are used for product separation in the mining industry.  Gravity belt filters are used to wash gypsum formed in coal-fired power plant scrubber systems. Bag filters are used in many industries where they compete with cartridges.

Automatic backwash filters have enjoyed the largest percentage growth in recent years. Originally, these filters were fitted with screens which could not remove particles smaller than 50 microns. The development of sintered metal allowed designs which can now remove particles as small as 5 microns. These filters find widespread use for purification of the side stream in cooling tower systems.

Major international suppliers include, Siemens, Ovivo, Xylem, Veolia, Amiad and Andritz. There are many media suppliers who manufacture the cloths and bags. They include Clear Edge, Sefar, National Filter Media and GKD.
