When choosing an ozone generator<\/a> there are many metrics and numbers used to rate ozone generators<\/a>. \u00a0Each of these terms is important, but which is most important for your specific ozone application? \u00a0<\/a><\/p>\n

The two most common metrics are ozone output, normally measured in g\/hr, or ozone concentration, normally measured in g\/m3 or % by weight.<\/p>\n

\"ozone<\/a>

Every ozone application is different. And based on your application the concentration or overall output of ozone production is more or less relevant.<\/p>\n

Ozone Output:<\/b><\/span><\/h3>\n

Normally measured in g\/hr or lb\/day<\/p>\n

The ozone output value is shown in a mass over time value that indicates mass of ozone produced in a given period of time. As flow rate of feed-gas through the ozone generator increases, however, the concentration of ozone decreases. This is a trade-off that exists across the entire flow-range of ozone feed-gas through most ozone generators.<\/p>\n

Ozone Concentration:<\/b><\/span><\/h3>\n

Normally measured in g\/m3 or % by weight<\/p>\n

Ozone concentration is the ratio of total feed-gas to ozone production. As flow rate of feed-gas through an ozone generator decreases, ozone concentration increases. As flow increases less of the oxygen in the feed-gas is converted into ozone as the contact time for the feed-gas in the ozone generator decreases, there is less time to produce ozone out of the given volume of gas.<\/p>\n

Ozone Applications:<\/span><\/strong><\/h2>\n

water Treatment:<\/b><\/span><\/h3>\n

When ozone is used to be dissolved into water ozone solubility becomes important. Solubility is the ratio of ozone gas that will dissolve into water based on physical conditions.<\/p>\n

Link to ozone solubility<\/a><\/p>\n

As ozone concentration increases the solubility of ozone into water increases. Therefore, ozone output in g\/hr becomes less relevant when dissolving ozone into water. Higher ozone dosages into water will require higher ozone concentration to achieve solubility into water. Overall ozone production is necessary to achieve desired ozone dosage rate, however, if ozone concentration at that production rate is very low, ozone gas will never dissolve into the water and be lost.<\/p>\n

There is a balance to ozone concentration vs ozone output when using ozone for water treatment. A simple rule of thumb, if you have the choice to use an ozone generation system that provides the same ozone output in g\/hr but at a higher ozone concentration, choose the higher ozone concentration every time.<\/p>\n

Air Treatment:<\/b><\/span><\/h3>\n

There are ozone applications where ozone is used in air treatment only. Odor removal,\u00a0food storage, etc. <\/a>In these applications, ozone concentration is much less important. Ozone output in g\/hr is the only factor that is relevant in most of these applications. More ozone mass will provide more ozone dosage into the air.<\/p>\n

Consider oxygen or air consumption along with power consumption in these applications.<\/p>\n

Groundwater Remediation:<\/b><\/span><\/h3>\n

Ozone used for in-situ groundwater remediation is normally diluted with air, to increase the radius of influence of the ozone gas in the water table. \u00a0Due to this dilution ozone concentration is not a major factor in this application. \u00a0Ozone output is the only major factor considered in this application.<\/p>\n

Cooling Towers:<\/b><\/span><\/h3>\n

Ozone is used for cooling tower treatment as a biocide in the cooling tower. \u00a0In these applications, very low ozone dosage rates are used in the water. \u00a0Therefore ozone concentration is not as important in many of these applications as ozone solubility is not as critical.<\/p>\n
