Ozone is known as one of the strongest oxidizing agents available. Packaged water producers also like to take advantage of its effect and operating principle because ozone dissolved in water reliably removes bacteria and viruses and then swiftly decomposes without leaving any residues. That is precisely the reason why an ozoniser ideally supplements the kit of all those who use a conventional filling process for their still water and want to be on the safe side with product quality. Now, Krones has expanded its portfolio of water-packaging equipment to include just this area of expertize, introducing an ozonizer developed in-house.
Microbiological stabilisation prior to filling guaranteed
The ozone generator integrated into the Krones Ozonomic works on the principle of dielectric-barrier discharge – It breaks down oxygen and forms ozone molecules added to the drinking water before filling it.
The ozone generator works exclusively based on compressed air to convert oxygen into ozone, so no separate oxygen supply is required. The downstream stainless steel injection system is operated at a pressure of two to three bars, which makes for efficient ozonization performance, even with high water temperatures or pH values. The typical amount of ozone added to still water is 0.4 mg per litre of product.
Double disinfecting power
The name alone denotes its close connections within the Krones portfolio – the Ozonomic and the water treatment systems from the Hydronomic family constitute a can-do team to meet the most stringent requirements for water quality. After the water has been treated in various modules of the Hydronomic series, it is passed through the Ozonomic, which guarantees its microbiological stability. A conventional process can then be used for packaging it without any impairment of quality and product safety.
Ozonisation even achieves disinfection twice over here – Not only does the ozone sterilize the water itself, but it also disinfects all container and closure parts coming into contact with the product.
