An investigation on the effect of the surface properties and the cloth structure of a filter medium on the operation of a filter bag was conducted using a pilot-scale testing device. The collection properties and the increase in the residual drop, as well as the mass of the residual dust embedded within the filter medium, were measured. Three filter media were investigated: a singed filter medium, a calendered filter medium, and one with a membrane-laminated surface. The experimental results obtained show that the operational characteristics of a filter bag is greatly influenced by the surface properties and the cloth structure of the filter medium. The calendered filter bag has an unfavorable operational quality concerning both the collection properties and the residual pressure drop. The hard thickening of the filter medium drives to the rapid clogging of the filter bag. In contrast, the other two filter media have favorable characteristics concerning the above two criteria. At the same time, it was found that after tests conducted for about 70 h each, the singed filter bag, compared with the membrane-laminated one, exhibits a lower residual pressure drop, although more particles are deposited inside. The lowest filtration cycle duration was recorded by the calendered medium, whereas the cleaning frequency by the other two media was nearly in the same range.
