There are a number of key points you need to have to know before you can acquire an ozone generator. Just before going into details, however, it is important to note that we are speaking about corona discharge sort ozone generators. These are the most vital kind of commercial/industrial ozone generators. There are other kinds of ozone generators, but non corona discharge units are mainly for use in smaller scale applications, creating generally significantly less than half a pound per day or significantly less than 10 grams per hour of ozone.
This short article will evaluation the crucial choice aspects and how it relates to different applications for ozone and the effect on the cost of an ozone generator.
The key aspects consist of:
1. Output: This is how a great deal ozone the machine makes, normally quoted in grams per hour or pounds per day.
two. Concentration: Ozone can be made at unique concentrations ranging from 1-12 weight %. The concentration of ozone has an effect on most applications and also affects machine output.
3. Gas Feed: you should have a source of feed gas containing oxygen, there are 3 possibilities: dry air, oxygen concentrated from air or bought oxygen (either as liquid oxygen (LOX) or compressed oxygen in cylinders).
four. Generator Cooling: Ozone generator generate heat that have to be removed, the choices for removing this heat are air cooling or water cooling.
Selecting the proper mixture of characteristics depends strongly on the application. For example, in water remedy applications higher concentrations of ozone are used while in air treatment applications lower concentrations can be chosen.
Ozone Generator Output
This is the most significant issue in selecting an ozone generator. northern CA commercial power generator rental of ozone required is primarily based on the application specifications. If the ozone is becoming made use of for removal of organic contaminants from water, the amount of ozone is proportional to the quantity of organic in the water, the efficiency of the ozone organic reaction and the efficiency of dissolving the ozone into the water.
As a precise instance, ozone is generally applied to cut down chemical oxygen demand (COD) in water. COD is measured in ppm (milligrams per liter – mg/l). It generally takes 2 mg of ozone per mg of COD to get rid of the COD. So, if we had to treat 10,000 liters per hour of water containing 50 ppm of COD we would have to have:
ten,000 liters/hour X 50 mg/l COD x 2 mg Ozone/mg COD = 1,000,000 mg/hour
1,000,000 mg/hour = 1,000 g/hour = 1 kg/hour
So, we would need to have to dissolve 1 kg/h of ozone (or 52.8 pounds per day of ozone)
Less than 100% of the ozone injected in the water dissolves, so we need to have to know the ozone transfer efficiency. A effectively made venturi injection technique can dissolve at least 90% of the ozone. For the case above, you would require 1 kg/h ÷ .90 = 1.11 kg/h (58.7 pounds per day of ozone). This is the amount of ozone we would have to make at the targeted concentration to dissolve the 1 kg/h of ozone into water.
Significant: A given technique will make less ozone as the concentration of ozone increases. Ozone transfer efficiency, the rate at which ozone dissolves into water increases with increasing ozone concentration. Both variables will identify the final size of the machine expected.
Determining the quantity of ozone required, except for the simplest applications, needs laboratory or pilot research combined with an engineering evaluation to select the correct balance amongst ozone dose, concentration and generator size. Commonly, an ozone generator business will not be capable to offer this data. If they can enable, there will be an more expense for conducting the studies.
Ozone Concentration
As noted above, ozone concentration can influence both the effectiveness of ozone in a offered application and the amount of ozone that can be produced from a provided ozone generator. Primarily, higher concentration ozone charges a lot more, but can do extra in specific applications. Commercial corona discharge systems make anyplace from 1 weight % ozone to 12 weight percent ozone. Gas therapy applications typically use the 1-3 percent range although water therapy application typically use 5-ten %.
An important aspect of ozone concentration is in comparing diverse ozone generators. Manufacturers use distinctive bases for claiming the nominal output of an ozone generator. Ordinarily, you have to study the fine print to see what concentration they use to claim a given production price.
