System Configuration
A pharmaceutical water ozonation system (shown in Figure
1 below) typically uses three ozone measurement points:
1. Following the ozonated water storage tank.
2. Following the UV ozone destruction lamp to confirm
no ozone is going to the distribution loop.
3. At the end of the distribution loop, to verify that
adequate levels of ozone have reached the entire
distribution loop during sanitization with the UV
ozone destruction lamp off.

A semiconductor ultrapure water system typically does not
shut down for sanitization and omits the third measurement
point.
