Ozone generators are a popular way to clean the air in your home, but how effective are they? In this blog post, we’ll take a look at some of the most important metrics of measuring ozone generator performance. We’ll also discuss how ozone generators work and what you need to know before purchasing one. Keep reading to learn more!

Ozone Production

The most popular method of reporting ozonation is in g/hr, however it can also be shown as mg/hr, lb/day, or another unit of measure. The ozone production value must be shown in a mass over time value that indicates the amount of ozone formed during a specified length of time. The value for this option is a calculated number that takes into account the amount of ozone in the feed gas.

Ozone Concentration

The measurement of ozone concentration is a measure of the ratio of ozone to feed gas produced by the ozonator. This is a real-time measurement obtained with a high concentration UV Ozone Analyzer. The percentage of ozone concentration may be displayed as percent by weight, g/m3, or another unit of measure that depicts a quantity of ozone at any one moment.

Feed-gas

The feed-gas for the ozone generator may be either oxygen or air. To figure out what gas was used, and what gas is required to get similar results, this data must be available. Oxygen purity, or dew-point measurements in air would be beneficial information.

Flow-rate

The given flow-rate of gas is required to compute the reported ozone concentration and produced. Ensure that measured flow is adjusted for pressure using a manual float type flowmeter, because pressure needs to be accounted for. We’ve discovered some performance charts that were made using direct readings from manual flow meters without taking pressure into account, which gives a false low flow rate, high ozone concentration, and high ozone production rate.

Feed-gas Pressure

The feed-gas pressure would be the pressure of the fed gas on the corona cell of the ozone generator. Ozone production by some ozone generators may vary depending on gas pressure on the corona cell. As a result, you could observe a performance graph that shows how ozone production is related to pressure.

Power Setting

An increase in the ozone generator’s power setting may be used to demonstrate how ozone output varies with changes in the adjustable ozonator dial or remote signal. This can be shown by a percentage or particular indication on the dial.

Power Consumption

The net result or change in power consumption based on the power setting value of the ozone production may be shown as a function of power usage. This would show how much energy is consumed by the ozonator with respect to an ozone production rate. This data may be used to calculate the electrical efficiency of the ozonator.

Bottom Line

A ozone generator is an electronic device that emits ozone gas. Ozone gas is a powerful oxidizing agent that can kill bacteria, viruses and other organisms.  Ozone generators are used in a variety of settings including hospitals, schools, offices and homes to disinfect the air and surfaces. Keep in mind the above discussed metrics of measuring ozone generators before purchasing one.
