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.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
