Abstract: An underdrain filter or strainer for use with power generation and ion exchange facilities, such as, but not limited to, deep bed demineralizers used in nuclear power plants deep bed ion exchangers. The filter is fabricated from a sintered, stainless steel mesh or wire-cloth filter media having a pore structure with pore size ranging approximately from one micron to two hundred microns. The filter media is composed of a plurality of filter media layers including a perforated inner core bonded to at least one drainage wire mesh, a filtration wire mesh, and a protective wire mesh forming an outer diameter, the layers being diffusion bonded to form a single monolithic laminate.

Abstract: A precoat filtration element for a condensate polisher system that yields high weld strength in the form of a septa having a core with a plurality of perforations and wound filter elements, the wound filter elements wound around said core, and the septa including an extension flange at one end; and an end fitting having a solid base and a threaded post, the end fitting being slideably engaged within the extension flange such that an outside wall of the solid base is in mechanical contact with an inside wall of said extension flange, and upon insertion, the threaded post is coaxial with the septa center axis, and extends longitudinally outwards away from said septa. Spot welding the end fitting solid base to the extension flange provides high tensile strength over prior art designs.
