Patent ID: 8771513

Claim:
A filter system for membrane-separated and adsorptive treatment of a liquid containing at least one target substance to be filtered, comprising a housing having an upper end, a lower end, an inlet opening at said upper end of said housing, at least a first three-directional valve connected outside said housing to said inlet opening, an outlet opening at said lower end of said housing, at least a second three-directional valve connected outside said housing to said outlet opening, a side opening in said housing between said upper end and said lower end, and at least a third three-directional valve connected outside said housing to said side opening, said housing containing a plurality of hollow fibre membranes with pores, said hollow fibre membranes arranged so as to form a reaction vessel inside said housing but not touching said housing, resulting in creation of an intra-luminal area inside said reaction vessel and an extra-luminal area between the hollow fibre membranes and said housing, said extra-luminal area capable of being filled with at least one adsorber material, with said hollow fibre membranes arranged in such a way that said inlet opening at said upper end of said housing opens into said reaction vessel, and at the bottom of said reaction vessel a screen, said screen creating a liquid area between said lower end of said housing and said screen, with said side opening in said housing being located below said screen and above said lower end, being arranged in such a way that regeneration of said adsorber material by reverse fluid flow is possible.
