Abstract: The filtration behaviour of woven and nonwoven fabrics at different air flow rate, dust feed rate, dust loading, time intervals and dust particles has been studied. It is observed that the pressure drop increases with the increase in airflow rate for both the woven and nonwoven filters. In general, the pressure drop in case of woven filter is found to be higher than that in case of nonwoven filter. In case of woven fabric, in general, the filtration efficiency and the pressure drop increase with the time interval, but the rate of increase is found to be different for different types of dust particles, i.e. the distribution of size of dust particles. The cleaning efficiency of woven filter in case of clay is found to be lowest followed by sand and Sipernat mixture. The outlet dust concentration in case of woven filter reduces with the time and in case of clay it is highest as compared to the other dust particles. In case of nonwoven filter, with the increase in air flow rate the increase in pressure drop is found to be more at constant dust loading than that at constant dust feed rate. The filtration and cleaning efficiencies of nonwoven fabric, for a certain type of dust particle, are found to be affected by the dust feed rate and the air flow rate.
