Ｖｔ５ｅｃ／（：Δとなる。On the other hand, the correlation between the UV sterilization dose of the UV lamp required to sterilize bath water and the sterilization rate in one pass was investigated in the 8th paper.
As shown in the figure. Bath water (106 bacteria/1ttl) is poured into a sterilizer containing an ultraviolet lamp, the number of bacteria is measured before and after the inflow, the sterilization rate is determined, and the ultraviolet irradiance (μ1) is calculated. This is a graphical representation of the correlation between the product of the transit time inside the sterilizer (referred to as the ultraviolet sterilization dose). The sterilization rate increases linearly at an ultraviolet sterilization dose of 10 to 105 μW. However, under 10μ Iku9', the sterilization rate is less than 90%, and even compared to the number of bacteria of 10'/ml before inflow, the number of bacteria is 105.
It is hard to say that it is sterilized based on the quantity/zl level value. On the other hand, at 105 μW or more, the sterilization rate remains constant at 99.9999% regardless of the ultraviolet sterilizing dose, and the number of bacteria also shows a single-digit value of several bacteria/liter. Therefore, the optimal UV germicidal dose for one pass is 10 to 105μ

これは、１０６個／ｍｌ レベル値が生菌できる上限

(The results of sterilization at 1/m are shown in Figure 9.
The irradiation material is low F1! +203 containing silicate glass) stored in a 1.51 container, a 13 W (ultraviolet irradiance 55 μW/cd) ultraviolet lamp stored in a 1.0 e container, and a circulation flow rate of 221/m. In this case, the UV sterilization dose in one pass is 28μWsec/
