The challenge
uShaka Marine World keeps marine and freshwater animals in multi-species life support systems, including systems where mammals and fish share the same water. The life support water needs continuous disinfection to control bacteria from animal waste. The disinfectant cannot leave a damaging residual in the water that returns to the animals.
The solution
Biozone supplied the ozone systems for uShaka’s life support water and has maintained them since. At uShaka, ozone is the primary disinfectant in the multi-species marine and freshwater life support systems.
- Ozone generation: 12 SOZ 400G and about 10 SOZ 200G ozone generators, using oxygen-fed ozone generation, for a total system volume of 3 to 5 million litres of marine life support water.
- ORP control: dosing is controlled by oxidation-reduction potential (ORP) monitors and controllers.
- Bacteria control: continuous, ORP-controlled ozone dosing helps control bacteria from animal waste in the life support water, which is monitored.
- Treatment process: ozone dosing works alongside protein skimming and deaeration. Deaeration manages the saturation of gas in the water and is designed to stop residual ozone returning to the animals’ water, supporting systems in which mammals and fish share the same water.
- Continuous dosing: ozone is generated on site and dosed continuously, so the systems rely less on stored chemical disinfectants that have to be bought in and topped up.
The result
- Biozone ozone systems have been in continuous operation at uShaka Marine World since 2005.
- Ozone dosing is ORP-controlled.
- Biozone has supplied and maintained the ozone systems throughout.
