“…In terms of filtration, numerous researchers are working on developing media with higher filtration efficiency and lower pressure drop. The dust-carrying performance and pressure drops of different media were studied by Zhang and others [112] , who found that the pressure drop of a H14 PTFE medium was about 140 to 370 Pa when the load dust mass is 0 to 6 g/m 2 , while it was about 220 to 370 Pa for a H14 glass fibre. The energy consumption of H14 glass fibre was about 1.57 times that of H14 PTFE.…”

“…High-efficiency particulate air (HEPA) filters have been used in various fields to maintain a clean air environment for industrial facilities, such as producing semiconductor and LCD panels, bio-pharmacies, and nuclear power plants [ 1 , 2 , 3 ]. In general, glass fibre has been applied to HEPA filter media.…”

“…Polynomial approximation thus appears to be more universal as it can be used to fit various loading curves more accurately. This is also obvious throughout the literature where polynomial fit is reliably used to optimize and analyze performance of filters in various applications such as airliner cabin filters [ 23 ], engine air intake [ 15 ], or evaluating the HEPA filter media [ 14 ]. Comparing the coefficients of determination (R 2 ), we can see better tightness of polynomial fit compared to the exponential.…”

“…The parameter a expresses the distance of the loading curve intersection on the y -axis from zero, which can be approximated by initial pressure drop Δ p i : while b can be expressed from logarithmized Equation (5) and setting required conditions. The average pressure drop can also be modeled by a 4th order polynomial according to 4/11 Eurovent calculation [ 13 ] as previously used by several researchers [ 14 , 15 ]: where v , x , y , and z are the fit parameters of the polynomial. Average pressure drop is a function of dust load and can be generally described as follows: where M is the final amount of dust loaded.…”
