ABSTRACT:
A sanitary filtration plant including an oblong, tubular pressure vessel having one or more helical filter elements. Each helical filter element has a spiral-wound filter member and a central tube and, at an outlet end, a supporting structure formed as a wheel with a hub, spokes and a rim. The plane side of the downstream face of each supporting structure is provided with a plurality of recesses that are positioned between an opening between the spokes and the external periphery of the rim and extend circumferentially so as to be substantially concentric with said rim.
