How does the Ozone Generator work?
The ozone generator takes oxygen (either from the outside atmosphere or a tank of pure oxygen) and runs it through an electrical arc (similar to a small artificial lightning bolt), which causes the Oxygen (O2) to go through "photolysis". This is were the O2 (Two oxygen molecules), are split into two single oxygen molecules. These single oxygen molecules then bond with the remaining oxygen(O2) to form ozone (O3).
The ozone is dosed into the water using a venturi. The venturi is a plastic fitting that has an inlet and outlet, and a nozzle for attaching the Teflon tubing from the ozone generator.
From the inlet of the Venturi, the path starts to narrow, until it reaches the middle of the fitting where it suddenly expands. When water passes through the venturi, the sudden change from a narrow passage to a large one, creates a vacuum. This vacuum pulls the ozone from the ozone generator, through the Teflon piping, and into the water dosing it.
In order to control the amount of ozone being dosed into the water, you will need to install a by-pass (not included) around the venturi. This will then allow you to control how much water goes through the venturi, and around it. For example, if you want a higher ozone level dosed into the water then you will want to put more water through the venturi, and less around it. On the other hand, if you want a lower dosage you will want more water to go around the venturi, and less through it. You can then test the level of ozone present in the water, using an ozone testing kit (not included).
Keep in mind that to get the most efficient ozone dosing you from the system, you will require the correct size venturi and an adequate flow rate through the venturi. If you are taking water from a tank or non-municipal source, then you may require a booster pump in order to get the right flow rate through the venturi in order for the ozone to dose. Please see below the venturi size, the flow rates for them, and the recommended size booster pump for each venturi.
