Abstract
Efficient sterilization of a flow of fluid containing a pathogen/virus contaminant is achieved by filtering the fluid while exposing the contaminant to mechanical abrasion against a component of the filter system, ionization with material formed as a result of interaction of UV-radiation with an element of the filter system, and direct irradiation of the contaminant with UV-radiation.
Claims20
A method for filtering a fluid, the method comprising:
- with the use of a first filter system that includes a first structural layer, a second structural layer, and a third structural layer:
- passing said fluid along a first direction of flow of said fluid through the first structural layer that is defined by a first array of first rods, the first rods extending substantially along a first axis, immediately neighboring first rods being separated from one another by first gaps;
- receiving the flow of said fluid through the first structural layer at the second structural layer defined by a second array of second rods that extend substantially along the first axis and that are substantially staggered with respect to the first rods, and transmitting the flow of said fluid through the second structural layer;
- reducing pressure of the flow of said fluid by passing the flow through a third structural layer spatially separated from the second structural layer in the first direction;
- and
- irradiating said second array with radiation having a working wavelength and arriving at the third structural layer in a second direction.

A filter apparatus configured to filter a fluid, the system comprising:
- a first filter system including:
- a first structural layer defined by a first array of first rods that extend substantially along a first axis, wherein immediately neighboring first rods being separated from one another by first gaps;
- a second structural layer defined by a second array of second rods that (13a) extend substantially along the first axis, and (13b) are substantially staggered with respect to the first rods when viewed along a normal to the first structural layer to cause impact between a component of the fluid passing through the first structural layer towards the second structural layer and the second array prior to transmitting said fluid through the second structural layer;
- and
- a third structural layer separated from the first structural layer by the second structural layer, the third structural layer being dimensioned to reduce pressure of a flow of said fluid, which has passed through the first structural layer and then through the second structural layer in a direction of said normal, upon passing of said fluid through the third structural layer;
- and
- a source of radiation configured to generate radiation at a working wavelength in a chamber of the filter system, the chamber being separated from the first structural layer by the second and third structural layers.
