Airborne disinfection device using UVGI (Ultraviolet Germicidal Irradiation).
Reduction of the microbiological air contamination in highest safety conditions in presence of personnel.
DOSES OF UV AT 253,7 NM NECESSARY TO INACTIVATE SOME SPECIES OF MICROORGANISMS FROM 90% TO 99,99%
The illustration evidences the doses of ultraviolet radiations necessary to destroy different microrganisms.
As we can see, the fungine spores are obviously the most resistant species, compared to viruses and bacteria.
Aspergillus niger and Rhizopus nigricans are the spores more resistant to the short wave length ultraviolet radiations.
Penicillium is 10 times more sensible, while Cladosporium and Aspergillus flavus can be eliminated just with half dose used for more resistant spores.
MICROBIOLOGICAL ANALYSIS
The goal of this analysis has been the evaluation of UV STERIL AIR SYSTEM - GENIUS 485J CTI efficacy in the air sterilization process and the lasting of its effect.
For the experiment it has been prepared a room hermetically closed; the volume of the ambience is about 38 m3 (5x3x2,5m).
The room has been sterilized before every trial, to avoid crosscontaminations during the analysis.
Resistant fungine species have been used for the experiments.
Then the room has been contaminated atomizing biological suspended particles with a sprayer called “ULTRALITE” that atomizes particles with diameter from 20 to 80μm, situated in the middle of the room, at about 2,5 m distance from UV STERIL AIR SYSTEM - GENIUS 485J CTI.
The controls have been done with system “S.A.S, super 90” (International PBI, Milan) which can inspirate wellknown air volumes.
Every trial included 2 series of drawings in two different point of the room, respectively in the centre and in the opposite side.
The results indicated are expressed in U.F.T./m3 .
The formula of UV lamps efficiency is given by the spores destruction percentage:
- e% = (spores destroyed/initial spores) x 100
- e% = [(t1 – tn)/tn] x 100
- tn = t2, t3, t4, t5, t6.
The results state the microbiological destruction efficacy of more reistant spores (Aspergillus niger and Rhizopus nigricans) in 150’.
In short, as from the results obtained, we can state that UV STERIL AIR SYSTEM - GENIUS 485J CTI has actually demonstrated how can definitely destroy the environmental microbiological contamination, in the shortest time.
Therefore it can be used in every ambience where protection and sanitary control are required.
