| Ozone for Biological Control and Oil Removal? Ultraspin includes Ozone treatment of the water as an option for biological control. Ozone does this job very effectively. Some reclaim vendors claim that oil & grease concentrations can be reduced when using ozone. Is this true? Does ozone reduce oil and grease concentrations? We have conducted our own trials to determine the efficiency of ozone in reducing the oil concentration of an oily water mixture. We injected ozone into a small volume of oily water at a rate of 20 g/h. This concentration of ozone is higher that most commercially available ozone systems. We continued injecting and circulating the water for 45 mins. The result? Almost no change in oil concentration! It only went down by 15%. Chemical reaction calculations show that it would take 90 hours to destroy all oil under perfect conditions assuming complete mixing and complete uptake of ozone in water. In other words Ozone is not very good at reducing oil and grease concentrations. |
