MULTI-ELEMENT STRUCTURED ARRAYS (MESA'S) FOR COST EFFECTIVE AND HIGH EFFICIENCY TREATMENT OF FLUIDS

摘要

Multi-Element Structured Arrays (MESAs) present an effective approach to utilizing high pressure drop media that previously were cost prohibitive for use in a traditional filter element. The operational velocity is significantly slowed by the incorporation of numerous elements, thus, eliminating the Darcian flow resistances of the media. The MESAs are readily fitted with two or more replaceable "filter elements" that are able to employ commercially available media, microfibrous entrapped catalyst/sorbent media, unique multilayers and more. A model capable of estimating pressure drop for flow through a pleated filter can used as a design tool The model predicts minimum initial pressure drop, maximum filtration area, and media properties such as permeability and thickness. The model can determine dirt holding capacity, filtration efficiency, energy costs, and operational and ownership costs including blower energy, filter procurement and shipping, maintenance personnel, filter disposal, inventory and storage, and the cost of money.
