Within the application area of aquaculture, ozone is used in conjunction with re-circulating of water in aquaculture systems. The use of ozone with re-circulating water in aquaculture systems allows the user to benefit from a greater flexibility in site selection, reduced water usage, substantially improved water quality and reduced level of waterborne diseases. Ozone is responsible for reducing Total Suspended Solids (TSS) and Dissolved Organic Carbon (DOC), as well as controlling the level of Biochemical Oxygen Demand (BOD)/ Chemical Oxygen Demand (COD. The combination of these factors naturally leads to a reduction in effluent volumes, higher standards of environmental control, and a greater productivity.
