Continuous storage tank ozonation to a concentration of 20-50 ppb will prevent TOC build up and contamination of your high purity water, yielding <5 ppb TOC and <5 cfu/100 ml in ambient temperature water systems. By diverting a partial flow of your pure water to the LIQUOZON® Ultra system via a bypass line, the water is treated with ozone to a dissolved concentration between 0.02 - 0.05 mg/l and then returned back to your system in the return line. The UV ozone destruct unit at the beginning of your loop breaks down the ozone to an undetectable level before returning it to your main water stream.

Very low ozone concentrations in the magnitude of 0.1 to 0.2 mg/l are sufficient to sanitize the distribution loop and keep germ counts below 5 cfu per 100 ml.

With the UV destruct lamp turned off, a partial flow of pure water is taken from the tank via a bypass line and fed into the LIQUOZON® Ultra. Ozonated water is returned to the feed line of the loop. The dissolved ozone concentration is between 0.1 and 0.2 mg/l. The ozone concentration at the end of the loop is monitored. Once the concentration reaches the desired dissolved ozone concentration set point, the system is held at this concentration for 5 to15 minutes. At the completion of the sanitization cycle the ozone generator is turned off and the UV destruct unit at the beginning of the loop is turned on to break down the ozone to an undetectable level. Product water can be used again when no more ozone is detected.
