Air purification performance of polypropylene hollow-fibre membranes in submicron particle removal
Original language description
This work aimed to determine filtration performance of polypropylene hollow-fibre membranes (HFMs) for removing submicron particles from air. Experiments were performed in a glass chamber supplied with an aerosol of submicrometric particles. Two types of HFMs varying in packing density, active filtration area and pore-size distribution were tested in an outside-in configuration. By measuring the number of particles upstream and downstream of the HFM, the filtration efficiency was determined at a permeate velocity of 5 cm/s. Particle counting was carried out using a TSI 3075 condensation particle counter connected to a TSI 3080 scanning mobility particle sizer in 64 particle size channels from 16.8 to 572.5 nm. The results show high efficiency, mostly higher than 99% for particles above 100 nm size. The most penetrating particle sizes (MPPS) were between 22 and 30 nm with an efficiency of 95–97%.
