There are a number of key issues you’ll want to know earlier than you should purchase an ozonatorius . Earlier than going into particulars, nevertheless, it is very important be aware that we’re speaking about corona discharge kind ozone mills. These are a very powerful kind of business/industrial ozone mills. There are different kinds of ozone mills, however non corona discharge items are principally to be used in small scale functions, producing usually lower than half a pound per day or lower than 10 grams per hour of ozone.
This text will overview the important thing choice components and the way it pertains to numerous functions for ozone and the affect on the price of an ozone generator.
The important thing components embrace:
1. Output: That is how a lot ozone the machine makes, usually quoted in grams per hour or kilos per day.
2. Focus: Ozone could be produced at completely different concentrations starting from 1-12 weight %. The focus of ozone has an impact on most functions and in addition impacts machine output.
three. Gasoline Feed: you could have a supply of feed fuel containing oxygen, there are three decisions: dry air, oxygen concentrated from air or bought oxygen (both as liquid oxygen (LOX) or compressed oxygen in cylinders).
four. Generator Cooling: Ozone generator create warmth that have to be eliminated, the choices for eradicating this warmth are air cooling or water cooling.
Choosing the proper mixture of options relies upon strongly on the appliance. For instance, in water therapy functions larger concentrations of ozone are used whereas in air therapy functions decrease concentrations could be chosen.
Ozone Generator Output
That is a very powerful consider choosing an ozone generator. The quantity of ozone required relies on the appliance necessities. If the ozone is getting used for removing of natural contaminants from water, the quantity of ozone is proportional to the quantity of natural within the water, the effectivity of the ozone natural response and the effectivity of dissolving the ozone into the water.
As a particular instance, ozone is usually used to scale back chemical oxygen demand (COD) in water. COD is measured in ppm (milligrams per liter – mg/l). It usually takes 2 mg of ozone per mg of COD to take away the COD. So, if we needed to deal with 10,000 liters per hour of water containing 50 ppm of COD we would wish:
10,000 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 wish to dissolve 1 kg/h of ozone (or 52.eight kilos per day of ozone)
Lower than 100% of the ozone injected within the water dissolves, so we have to know the ozone switch effectivity. A properly designed venturi injection system can dissolve not less than 90% of the ozone. For the case above, you would wish 1 kg/h ÷ zero.90 = 1.11 kg/h (58.7 kilos per day of ozone). That is the quantity of ozone we must produce on the focused focus to dissolve the 1 kg/h of ozone into water.
Vital: A given system will produce much less ozone because the focus of ozone will increase. Ozone switch effectivity, the speed at which ozone dissolves into water will increase with rising ozone focus. Each components will decide the ultimate dimension of the machine required.
Figuring out the quantity of ozone required, aside from the only functions, requires laboratory or pilot research mixed with an engineering analysis to pick the right stability between ozone dose, focus and generator dimension. Usually, an ozone generator firm won’t be able to supply this info. In the event that they can assist, there can be an extra price for conducting the research.
