1. OZONE LEVEL IN NATIONAL GMP STANDARD
CLEAN ROOM AIR CLEANLINESS LEVEL TABLE
According to STANDARDIZATION FOR STERILIZATION TECHNIQUE.
1- 300,000 level ,C=2.55PPM=5mg/m3
2- 100,000 level, C=5ppm=10mg/m3
3- 10,000 level, C=15ppm=30mg/m3
4- 100 level, C=20ppm=40mg/m3
For planktonic : C=2~4ppm
For sedimentary bacteria of object surface : C=10~15ppm
2. OZONE DOSAGE IN AIR (SPACE) DISINFECTION
W = CV / S
W = the total amount of ozone
V = total volume (M3)
S = decay rate, S = 0.42
C = concentration of ozone disinfection workshop , mg / m3
3. SELECTION OF OZONE GENERATOR IN HVAC SYSTEM APPLICATION
1- How to calculate the actual disinfection volume? it consists of three parts
V1 means space volume of clean area.
V2 means volume of air duct, it can be ignored.
V3 means the fresh air volume supplied to keep the positive pressure of clean area.
V3≈ the total cycled air volume of HVAC system (m3/h) * 25% (regular fresh air turnover rate ) * 10~20% ( fresh air volume supplied to keep the positive pressure of clean area) *39% (budget value of half-life ozone ).
So V3= the total cycled air volume of HVAC system (m3/h) *1~2%.
2- take ozone air sterilization in factory for example
clean room requires 5ppm ozone concentration (C=5ppm), but in fact, the disinfection of clean area including both air sterilization and surface disinfection, so engineer choose 10ppm O3 concentration.
3- Engineering Data
disinfect the area S = L36m * W48m = 1728 m2
elevation H = 2.6 m
air duct volume of 100000m3 / h
4- According to the engineering parameters provided by the factory
V1 = S * H = 1728 * 2.6 = 4492.8m3
V2 is negligible
V3 = 100000 * 1.1% = 1100 m3
Total actual volume V = V1 + V2 + V3 = 4492.8 + 1100 = 5592.8≈5593 m3
Ozone dosage required W = C × V / (1-S) = 10 * 2 * 5593 / 0.4208 = 286.82 g / h
Piping, and other factors considered, choose ozone generator output 300g / h
1) . Ozone generator built in Domestic Patent High purity Ceramic /Quartz ozone tube with power supply.
2) . Ozone generator is cooled by air fan or water, good heat dissipation effect.
3) . Ozone generator built in oil free air pump as feeding air source to produce ozone gas.
4) . Ozone output could be regulated based customer’s demand
5) . Digital Ammeter for showing circuit with ozone regulated.
6) . Working timer can be set 0.1s ~99 hours
7) . Movable design , small size and compact.
8) . This type is easier and safer to be operated.
9) . Input voltage: 110V/60hz,220V/50hz.
