Determination of ozone in water by the indigo method ...

Visual methods can be used to measure mgl −1 ozone. Secondary oxidants produced by ozone in natural water, including hydrogen peroxide or chlorite, do not interfere; chlorine can be masked. The reagent solution is stable for 3 months. The method is recommended for kinetic measurements, for studies of ozonation processes and for visual field methods.

The Role of Ozone in Water Bottling | WQP

· The ozone/water contacting system serves two primary functions. First, it is used for the dissolution or mass transfer of the ozone gas from the output gas stream mixture of the ozone generator into the water to be treated. The balance of the ozone remaining in the off-gas is destroyed by an ozone decomposer unit so that any off-gas discharged into the atmosphere contains an ozone ...

How to Make Ozonated Water (for Drinking)?

· Ozonated water is made by running ozone gas through water. Special ozone resistant stones produce tiny bubbles which allow the gas to be suspended in water temporarily. For the best quality of ozonated water, it’s recommended to use an ozone generator which runs on pure oxygen as the feed gas (instead of air).
