Abstract:

Abstract. A study on the effect of a newly formulated filter aids onto two different types filter media that are teflon and Ryton was carried out in a laboratory scale filtration system. The filter aids material is a combination of PrekotTM and activated carbon which are commonly used as flue gas cleaning agent respectively. The effect of the filter aids of various combination on pressure drop and permeability across the two filter media under different filtration velocities was investigated in this study. Results showed that ryton presents a lower pressure drop under various combinations of filter aids for different filtration velocities compared to teflon. A lower pressure drop across the fabric filter resulted a higher permeability property of ryton which allows higher volumetric air flow rates passing through it compared to teflon filter. The study suggests that the addition of PrekotTM in the formulation of filter aids significantly affect both pressure drop and permeability of the filter media
