GRADIENT STRUCTURE MEDIA FOR LIQUID FILTRATION APPLICATIONS

摘要

Filter media with an engineered gradient structure can optimize the filtration efficiency, pressure drop, and holding capacity of media performance. An important part of establishing these properties for a specific application is to determine the porosity of the media design. Through media characterization, liquid filtration media can be designed to fit most applications. Kimberly-Clark Corporation has designed a unique media to provide improved filtration efficiency without sacrificing dirt-holding capacity. The media is 100% polyolefin and is thermally bonded for strength. This media is chemically compatible with most liquid applications and does not contain binders that can interfere with the fluid chemistry.This paper describes the parameters for developing a gradient structure and designing it for specific applications. The liquid filter media used in these applications clean better, clean longer and reduce end user costs.
