Ozonizers

As an introduction ozone is basically oxygen with three molecules of oxygen which is an unstable gas. That instability during the process of decay causes a very energetic oxidizing reaction (some might describe as a miniature molecular explosion) that can be used for destroying bacteria, virus, spores, etc.. This can be used for treating water, for water and air sterilization, for removing iron, cyanides, phenols, organic substances

Ozone generators can be used in a number of ways in the beverage industry and Enterprise Tondelli have been supplying them for over 30 years. They are typically used as:-

a sterilant for bottle rinse water,
product sterilisation,
water treatment in reducing some type of iron and manganese
as a cleaning medium where the use of chemicals is not preferred

They are easily useful in water bottling plants.

Ozone can be produced using an ozone generator which are skid mounted units ranging in size from 1,000 l/hr to more than 40,000 l/hr depending on application. Wed supply small units from 4 grm/hr – 80 grm/hr and many sizes in between – all skid mounted and with stainless control panels for accurate control. Now a small mobile unit using bottles oxygen is available for general cleaning.

Compressed air is fed to the water cooled ozone generation cell where an electric current passes through the air creating ozone gas. This is then dosed via a venturi into the water fed by a high pressure vertical pump. An ozone stabilisation or contact tank and in-line ozone analyser feedback loop ensures that the correct value is achieved before sending the water to the rinser or filler. Further enhancements ensure that the product pipe to the utility is always circulating ensuring ozone levels are always achieved at point of use. Returned ozonised water is stripped of ozone and reprocessed to avoid wastage either by UV or a carbon filter.

For product water sterilisation higher levels of ozone can be used which is then reduced by means of a carbon filter. Any excess ozone gas produced by the unit is destroyed by an on board catalytic destructor.

If the unit is being used to remove manganese or iron then the ozone unit is followed by sand and carbon filters to remove any particles that are precipitated out. Enterprise Tondelli have supplied couple of these as repeat orders. Care should be taken with the incoming water analysis as it is not suitable for some type of water………

Ozone units have the following benefits when used in a beverage plant application:-
