Air filtration using polymeric hollow-fibre membranes

abstract

en

The use of membranes for air filtration has significantly increased over the past decade. Their unique performance, chemical, surface and physical properties are preferred in a number of air filtration applications. The effort of this work is to introduce hollow fibre membranes to air filtration which, to the best of authors’ knowledge, have not been used, so far. This type of membranes can be used for microfiltration of air and to provide high efficiencies in particulate matter removal down to 0.3 µm sizes which is comparable with high efficiency particulate air (HEPA) filters. However, next issues must be solved. What are the pressure losses and thus energy demands for operation of these membranes? Is it advantageous in terms of the acquisition cost? And what about the operation costs? Together with particle capturing capability, is it able to accomplish the requirements for air filtration? To find out the answers to these questions is the main aim of this work.
