Ozone- Bacteria and Sterilisation Control
“Nature’s own disinfectant and odour killer”
We hear about the ozone layer but what is it and where does it come from?
Ozone, like air, is a gas made up of three parts oxygen joined together. They are joined together by vibration – electrical excitement. This is achieved in nature by lightning (Corona discharge) or by ultra violet light. Ozone is a part of our natural order and has a very important part to play in our very existence, from reflecting the Sun’s light rays to killing germs.
We have been able to create ozone at will, in small quantities, for many years. It is commonly used for room deodorization and killing germs/bacteria in the air and on surfaces, bacteria control in air conditioning, water treatment, general air sterilization, surface sterilization in meat and food cool rooms, instrument sterilization and much more. Ozone is used by hospitals, council water treatment plants, food manufacturers, fast food chains, in toilets/commercial washrooms, and in fact, anywhere sterilization is required.
So how do we create ozone?
We have said, nature creates ozone in two ways and we imitate that. Firstly, there are Corona discharge units. We create a spark across two electrodes, one positive the other negative. As with lightning, this creates a charge in the air. This charge covers a wider spectrum of vibration than needed for just ozone, so it creates not only ozone but around five other non-required oxides. This is referred to as dirty ozone.
Hand meters often read ozone and oxides as one, so give a false reading to the amount of actual ozone being generated. Secondly, we have ultra violet light tube units. The technology involved in this method is very precise. Tube manufacturers are able to make their tube create vibrations at specific wave lengths (width of band). These wave lengths are commonly measured in units of nanometer (nm). The smaller the nm (width of band), the tighter and stronger the wave length. The wave length for a germicidal tube, emitting 253.7nm gives sterilization by UV light only.
An ozone tube emitting 253.7 and 185nm gives sterilization by UV light and clean ozone. The use of ultra violet lamps at the correct wave length is a most effective way of disinfecting air and water. Ozone can also be used very effectively in rooms for deodorizing and disinfecting.
Are ultra violet tubes dangerous?
No, if given the respect that is needed and used as directed.
Our world is bathed in very strong UV light. These tubes are not as strong but precautions should be taken if you are in direct UV light, such as UV glasses, sunscreen, covering up, pretty much “slip, slop, slap.”
Ozone units are shielded so you don’t have to concern yourself with direct light exposure. As with water, you would not fill a room with water and then try to work in it all day without oxygen. The same applies with ozone – commonsense really.
Bacteria control units can be used twenty four hours a day, seven days a week, sterilising the air that passes through them. Ozone units can be used for a variety of areas for instance, room accommodation for deodorising and disinfecting, one unit being moved from room to room, but also of great value in bin rooms, as ozone slows and prevents vegetable scraps from rotting.
So, if you have a problem with bad odours in say a bin room or waste shute, toilets, hotel/motel, aged care facility, pub, club or restaurant or you have need of a cool room fixture to keep food fresh, please send an email with your details and we’ll be happy to assist you with your enquiry.
