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

Abstract
A method and apparatus (10) for killing microorganisms in a particle laden fluid medium (11) are disclosed. This method has the steps of providing a germicidal radiation for killing microorganisms (30) and a reflectors (40) for transferring and orienting of the germicidal radiation for killing microorganisms (30); providing a secondary flow (12) of a substantially particles free fluid; the secondary flow (12) is running along or flowing across the surface of the reflectors (40) and establishing a substantially particle free barrier environment maintaining clean the reflectors (40); orienting an emission of the germicidal radiation in a parallel array of beams (32), and passing the fluid medium (11) along a path aligned with the parallel array of beams (32). The apparatus arranged so that the maximum efficiency of use of germicidal energy is achieved, energy consumption for sterilization will decrease, reliability and period between maintenance will increase.
