Ozone has many uses and potential applications in the industrial space, and these applications continue to grow as the technology improves. Due to this many new applications require testing to determine if ozone is a good fit, and to size the proper ozone system on a large scale. This is where lab testing, or bench-scale testing may be useful.
Should you need help with your bench-scale or pilot testing, we would be glad to provide you the necessary equipment, or perform these tests at our shop with our labor.
We also provide advise and assistance to set-up a quality bench-test set-up using ozone. Below is a great example in the diagram with details on equipment below.
Description of operation:
Ozone generator produces ozone from oxygen supplied from an external source, or with the integrated oxygen concentrator if equipped. Ozone/oxygen flow should be low, 2 LPM or less. Ozone should be produced at the highest concentration possible to provide the highest solubility of ozone into water as possible.
Ozone Mixing Tank should allow ozone gas to be bubbled into the bottom of this reactor. This tank should be sized based on your test and should be a reasonable volume for the sample size you are dealing with. For example, a 1 liter sample volume should be treated in a 1.5 – 2 liter tank.
The tank design should be as tall as reasonably possible. We commonly use clear PVC pipe to construct this with, 2″ PVC pipe at 48″ tall will hold a 2 liter water sample with sufficient head space just fine. This tall column allows the best possible solubility of ozone into water as possible due to the height.
Dissolved Ozone Meter will measure dissolved ozone levels directly in the contact column. Using the submersion sensor ozone can be measured directly in the column with no water leaving the column or test chamber. Dissolved ozone levels up to 200 ppm can be accurately measured with the proper dissolved ozone meter.
Ozone Flow Meter can measure and regulate ozone gas flow rate to the column or to the ozone analyzer. This will ensure the proper flow of ozone is measured and used to validate your tests. Stainless steel flowmeters with all Teflon seals should be used for reliability and optimum ozone resistance.
Ozone Analyzer will measure the ozone concentration real-time of the ozone generated from the ozone generator. This will determine the exact ozone dosage rate entered into the water. The ozone analyzer will measure ozone in g/m3 or % by weight. Using the flow measurement from the ozone flow meter and online ozone calculators the exact g/hr of ozone produced can be calculated.
Three Way Ball Valves can be used to divert ozone gas flow to the ozone analyzer either directly from the ozone generator to measure ozone production, or from the ozone reactors off-gas line to measure ozone off-gas concentration. By measuring the concentration of ozone off-gas the precise ozone consumption rate can be measured. This can be used to determine ozone reaction rates for your testing.
Ozone Scrubber can be used to destroy all excess ozone and safely catalyze back to oxygen.
If you have any questions about modifying your existing set-up, or getting help setting up a new bench-test set-up with ozone, we would be glad to help. We sell and rent all the equipment you see used. We can also help you with the finer details of how and why.
