Information
Prefiltration
Prefilters are most commonly depth filter types and are most often constructed of non-woven or melt-blown fiber materials such as polypropylene, polyamide,cellulosic mixed esters, glass fiber, mesh or sintered metals, and (before the interdiction of its use on account of its carcinogenicity) asbestos. These fiber materials are constructed into matrices by the random deposition of either individual or continuous fibers whose permanence of positioning is sought through pressing,heating, gluing, entanglements, or other forms of fixing.The actual pores of such filter constructions are formed from the interstices among the fibers.As shown in Fig. 1, the random deposition of the fibers during construction of the filter matrix results in a broad retentivity distribution, which causes a wide band of particle retention. The retentivity distribution can also be influenced by the thickness of the individual fiber or the degree of compression of the matrix.Varying the different filter media will deliver a wide variety of properties;therefore prefilters can be manufactured for selected applications.For instance,polymeric properties can be chosen to ensure specific chemical, thermal,and mechanical stability, or to introduce adsorptive properties. Increasinglyuseful in today’s biotechnological applications, charged matrices may be advantageous to remove haze, colloidal substances, or other oppositely charged particles.
