Flow resistance evaluation through nonwoven filter media

K.-J. Choi*, Clean & Science Co., Ltd., USA

Flow resistance evaluation through nonwoven filter media is a critically important factor, especially for the liquid filtration applications.

When the stress is applied, an object deforms, commonly called as rheological phenomena for the liquid.

By utilizing a simple sample holder in a small chamber, the stress was applied to a liquid through nonwoven filter media, such as cellulosic, meltblown, synthetic fibrous and metallic filter media, the flow resistance was evaluated. The stress and responding strain were obtained the geometry of the chamber and measured flow rate.

Significant differences in the flow resistance results were experienced with various fluids used and with the different additives. It is believed that...
