紫外线反应器中的有效紫外线剂量取决于被照射水的传输和流速以及工厂的设计和水力行为。由于在这种系统中不可能进行直接和简单的剂量测量，因此有必要制定一种测试程序，以评估这种工厂的卫生安全性。B。将枯草芽孢杆菌（ATCC 6633）孢子悬浮在饮用水中，并在市售饮用水UV设备中以不同的流量（0.5至7.5m3/h）和透射率（3至80%;厚度10 cm）进行辐照。
硫代硫酸钠和腺苷被用作透射还原物质。由于孢子对紫外线的敏感性是已知的，因此可以计算反应堆中的有效剂量，作为每次试验的空间辐射暴露量。这些数据形成了一个单独的效率图。结果表明，该测试程序是适合于紫外线植物的消毒能力的评估和应用领域的估计取决于传输和被照射的水的流速。
The effective UV-dose in a UV-reactor depends on the transmission and the flow rate of the water being irradiated as well as on the design of the plant and the hydraulic behavior. Since there is no possibility for a direct and simple dose measurement in such a system, it is necessary to develop a testing procedure which estimates the hygienic safety of such a plant. B. subtilis (ATCC 6633) spores were suspended in potable water and irradiated in a commercially available drinking water UV plant with varying flows (0.5 to 7.5 m3/h) and transmission (3 to 80 %; thickness 10 cm).
Sodium thiosulfate and adenosine were used as transmission reducing substances. Because of the known UV sensitivity of the spores it was possible to calculate the effective dose in the reactor as space radiant exposure for each test. The data resulted in an individual diagram of efficiency. It was shown that this testing procedure is suitable for the evaluation of the disinfection capacity of UV plants and the estimation of the field of application depending upon transmission and flow rate of the water being irradiated.
