The report examines the effect of particle charge and electric fields on the filtration of dust by fabrics. Both frictional charging and charging by corona are studied. Charged particles and an electric field driving particles toward the fabric can greatly reduce the initial pressure drop and also give some reduction in the steady state pressure drop. Collection efficiency is also increased. Frictional charging is unusually erratic and corona charging limited by dust resistivity. Thus further work is required to develop practical devices. In long term or equilibrium conditions, nodular deposits attachd to fibers may be of major importance. These nodular deposits may act like check valves, giving a high pressure drop in the forward (filtering) direction, and a low pressure drop in the reverse (cleaning) direction. Thus these nodules are difficult to remove by reverse air flow. These nodular deposits, as well as electrostatic fields between adjacent fibers of a filter, appear to be electrostatic. This appears to be an important area for further research.
