Filter apparatus

A filter apparatus for the filtering of substances from a fluid having a filter housing (2) which bounds a filter space (6) and which has an inlet (3) and an outlet (4) for the fluid to be filtered and having a filter element (5) which is provided in the filter space (6) and which is designed and arranged such that the filtering fluid can only flow through the filter element (5) from the inlet (3) to the outlet (4) of the filter housing (2) in operation, wherein a heating device (10) is provided for the heating of the fluid which includes a microwave source (11) in order to act on the fluid by microwaves, the filter element (5) has an inner space (52) which is surrounded by a filter membrane (51), and the microwaves are brought into the filter space (6) from the inner space of the filter element (5).

A filter apparatus for the filtering of substances from a fluid having a filter housing (2) which bounds a filter space (6) and which has an inlet (3) and an outlet (4) for the fluid to be filtered and having a filter element (5) which is provided in the filter space (6) and which is designed and arranged such that the filtering fluid can only flow through the filter element (5) from the inlet (3) to the outlet (4) of the filter housing (2) in operation, wherein a heating device (10) is provided for the heating of the fluid which includes a microwave source (11) in order to act on the fluid by microwaves, a monitoring which prevents microwaves from acting on the filter space (6) if the filter space (6) is not completely filled with fluid, and a pump device (40) for the conveying of the fluid from the inlet (3) to the outlet (4).

A filter apparatus for filtering substances from a fluid comprising a filter for the fluid, a housing for the filter including an inlet and an outlet for flowing the fluid from the inlet past the filter to the outlet, a microwave energy source for subjecting the fluid to microwaves, a fluid-impervious wall interposed between the microwave source and the filter and constructed of a material that has at most a low absorption capacity for the microwave, a casing surrounding the housing, and a waveguide associated with the casing for directing the microwave from the microwave source to the fluid flowing between the inlet and the outlet, wherein the wall has an outer side and an inner side, and wherein the filter is disposed on the outer side of the housing.

A filter apparatus for the filtering of substances from a fluid comprising a filter housing which is transparent to microwaves, bounds a filter space and has an inlet and an outlet for the fluid to be filtered, a filter element in the filter space and which is configured and arranged such that the filtering fluid can only flow through the filter element from the inlet to the outlet of the filter housing, the filter element forming a central recess into which the fluid cannot flow, and a heating device for heating the fluid which includes a microwave source disposed in the central recess in order for microwaves to act on the fluid.

A filter apparatus for the filtering of substances from a fluid comprising a filter housing which bounds a filter space and which has an inlet and an outlet for the fluid to be filtered, a filter element in the filter space configured and arranged such that the fluid can only flow through the filter element from the inlet to the outlet of the filter housing, and a pumping device for flowing the fluid through the filter element comprising a rotary pump having a bearing-free, magnetically journaled rotor causing a flow of the fluid through the filter element.
