Air Filtration Using Hollow-Fiber Membranes: A Comparison of Theoretical Models for the Most Penetrating Particle Size and Dimensionless Permeability with Experimental Data
Original language description
Hollow-fiber membranes (HFMs) have been widely applied to many liquid treatment applications such as wastewater treatment, membrane distillation and membrane contactor/bioreactor applications. However, they have rarely been used for aerosol filtration thus far. In this work, we compared mathematical models developed for predicting the most penetrating particle size (MPPS) and dimensionless permeability, applying them on the structural parameters of polypropylene HFMs. MPPS were compared with experimentally measured value using a monodisperse (20, 35, 50, 70, 100, 140, 280 and 400 nm) and a polydisperse aerosol (15–594 nm). Dimensionless permeability was predicted using models based solely on solid volume fraction (SVF), assuming isotropic 3D pore structure. The results were then compared with air permeability, which was measured using a Quantachrome 3Gzh capillary flow porometer. In the experiments with the monodisperse aerosol, no penetration was observed regardless of particle size. Therefore, face
