Industry (INDA), nonwoven filters made from synthetic fibres are the largest dollar end use nonwovens market and arguably the most profitable segment in North America, while nonwoven filtration media made from natural fibres, such as wet-laid cellulose filters, are highly price-competitive and have dominated in applications such as coolant filtration, baghouse filtration media, vacuum cleaner bags, and many HVAC applications. 

Industrial filtration systems may be of many types. The most common type is the baghouse shown in Fig. 29-3. The filter bags are fabricated from woven material, with the material and weave selected to fit the specific application. Cotton and synthetic fabrics are used for relatively low temperatures, and glass cloth fabrics can be used for elevated temperatures, up to 290 C. 

Gas Filtration Vendors are the primary source for sizing baghouses, however the process engineer should at the very least make an estimate of the pressure drop requirements for an intended system. The pressure drop will, of course, provide information needed on the approximate size of the fan needed, and the energy requirements needed to operate a system. In fact, pressure drop is the primary parameter in establishing particle removal efficiency for a fabric filtration unit, and hence, is usually the starting place for discussions with the equipment supplier. 

Cleaning period The total elapsed time that a section of the baghouse is off-stream for cleaning. (This time increment determines the total availability of section fabric for filtration use.)...
