Flow diagram of a typical ozonation system
  Water to be treated, eg aquaculture water or industrial process water |
 Mechanically filter the water using AFM pressure filter. This will remove solids and reduce the ozone demand. |
  Continue the filtration with a cartridge filter down to 1 micron. This will further reduce the COD and remove a high percentage of the bacteria. |
 Ozonated water enters a storage tank with a
minium of 10 minures residence time. Redox potential is monitored
|
  If you want protein skimming, a range of units up to 36 cubm/hr are available. Maximum ozone level is 0.1mg/l. |
 For heavy duty applications, use a counter current ozone contactor. Each column will cope with 100 cubm/hr and 20g/hr of ozone. |
 A redox monitor is fitted to the storage tank and interlocked to the ozone generator to control the ozone concentration |
 A UVc unit is used to treat the water after the storage tank. The UVc photreduces the ozone and gives a burst of free raicals which enhances the process |
In marine systems it is best to use a pressure filter after the UVc unit. The carbon will remove any residual ozone, and hydrobrmous acid. |
|
The treated water is now safe to use in aquaculture or industrial application. |
As a safe guard in aquaculture system, montor the redox potential again. An interlock with the generator provides fail safe operation |
