Method and apparatus for killing microorganisms in a fluid medium

An apparatus for killing microorganisms in a primary flow of a fluid medium using a germicidal beams as a means for killing microorganisms in a straight portion of the flow of the fluid medium containing particles and microorganisms, the apparatus comprising:

• a means for passing a primary flow of a fluid medium containing particles and microorganisms, the means for passing having a straight prime conduit, a means for killing microorganisms, said means for killing being an emission of germicidal beams;
• a plurality of means for transferring the emission of germicidal beams, the plurality of means for transferring including at least one means for transferring and orienting the emission of germicidal beams into an array of substantially parallel beams aligned along the flow path of the fluid medium in the straight prime conduit;
• at least one of said means for transferring being immersed in said fluid medium;
• a means of energizing said means for killing microorganisms;
• a means for passing a secondary flow of a substantially particle free portion of said fluid medium;
• wherein said means for passing causes said secondary flow to run along or flow across the surface of said means for transferring which is immersed in said primary flow to establish a substantially particulate free barrier environment maintaining clean said means for transferring.

A method for killing microorganisms in a flowing air medium using germicidal beams as a means for killing the microorganisms in a straight portion of the flow path, the method comprising of steps of:

• providing a primary flow of air containing particles and microorganisms;
• providing a means for killing microorganisms, the means being an emission of germicidal beams, said means being immersed in said air containing particles and microorganisms along a straight portion of the flow path;
• providing a plurality of means for a transferring the emission of the germicidal beams, at least one of said means for transferring being a means for transferring and orienting of said emission of the germicidal beams, said means for transferring and orienting orients the emission in an array of substantially parallel germicidal beams aligned along the straight portion of flow path, at least one of said means for transferring being immersed in said air;
• providing a secondary flow of substantially particle free air, said secondary flow is running along or flowing across the surface of the at least one of said means for transferring which is immersed in said air and establishing a substantially particulate free barrier environment maintaining the means for transferring clean;
• providing means for energizing said means for killing microorganisms and energizing said means for killing microorganisms.
