allows for long-term storage
Novozone has supplied ozone systems for the beverage industry since 2001. We are the New Zealand, Australian and Pacific Island agents for the Wassertec range of bottled water disinfection and bottle rinsing systems.These advanced systems are designed to meet Coca-Cola specifications and focus on quality, reliability, safety, ease of operation and maintenance. Production rates range from 10,000 to 60,000 litres per hour.

Ozone simultaneously disinfects the water, bottling equipment, the air above the water and the sealed cap of the bottle. This gives consumers a fresh, clean and pure product which they have come to expect.
Ozone has become the industry standard for purifying bottled water since it was approved by the United States FDA in 2003.
It is a highly effective and convenient disinfectant. Unlike chlorine, ozone does not leave any unpleasant aftertaste. But ozone is an extremely powerful oxidiser which physically destroys microbial contaminants by bursting their cell walls. A study by Dr.-Ing Uwe Huebner published by the US National Institutes of Health showed ozone to be a more powerful disinfectant than chlorine or silver.
Ozone is a naturally occurring molecule which quickly breaks down into oxygen and leaves no chemical residue.
Bottled water companies rely on ozone to eliminate impurities and deliver a safe and reliable product to customers.
Disinfectant efficacy comparisons
This diagram shows the relative efficacy of different disinfection agents [Huebner, R, 1973].
It clearly shows that ozone has a much higher efficacy than alternatives such as Chlorine dioxide, Chlorine and Silver.
How much ozone is needed?
Under ozonation may allow pathogen to develop in the bottle and potentially cause a product recall.
Over ozonation can create disinfection byproducts (DBP's) such as bromate.
The concentration (C, in ppm) of the dissolved ozone multiplied by the time (T, in minutes) of contact between the dissolved ozone and the pathogens in the water provides a 'CT' value.
The International Bottled Water Association (IBWA) recommends a CT value of 1.6 for effective sanitation.
For example, 0.4 ppm dissolved ozone in contact with the water for 4 minutes provides a CT value of 1.6
Ozone infused water has also shown benefits in the food services industry.
Seafood, meat and produce processors can reap more benefits by infusing ozone in the ice. It ensures no bacteria or other pathogens are transferred to the product.
The shelf life of fish stored on ozonated ice showed a 33% increase.
Novozone supplies, services and retrofits bottled water ozone systems with a capacity from 1,000 to 60,000 litres per hour in New Zealand, Australia and the Pacific Islands.Contact us to discuss your requirements
