Leading Edge Technology

High technology products, designed specifically for the
food industry, for purifying water, food produce and related
equipment:
• Control waterborne microbes (bacteria, viruses, protozoa,
etc) including common pathogens such as E Coli,
Salmonella, Giardia, Cryptosporidium and Pythium.
• Also control microbes on surfaces of equipment and food
stuffs by spraying ozonated water or dipping produce in
ozonated water.
• Retard growth of fungi, moulds and algae.
• Remove odours from water and other liquids.
• Remove off-tastes from products such as wine barrels and
corks.
• Remove colours from water.
• Oxidise chemicals including phenols, manganese, COD.

 

Ozone really is the ideal disinfectant for the food industry. It
is 90 times stronger than chlorine and kills cellular microbes
3,000 times faster. Yet it leaves no chemical residue and is
generally harmless to foods. It requires no consumables as it
is generated on-site electrically.


 

How Ozone Works

Ozone was approved by the USA FDA for use in the food
industry in 1997 and for bottled water in 1982. It is approved as a food processing aid in Australia, Japan, the EEC and the USA. It is used by over 3,000 municipal water authorities, worldwide.
Ozone is made from life-giving oxygen. The oxygen is
passed through a plasma field where ozone is created. It is
then dissolved in water. It kills microbes by a process of
oxidation. It then converts back into oxygen and leaves no
chemical residue whatsoever.
Our Ozone Water Purifiers are Fully Integrated Systems,
as preferred by the Food Industry. We are one of very few
companies in the world with this approach - we take the
"hassle" out of your plant. A large number of components
are carefully designed, balanced, pre-connected (electrics,
pneumatics, hydraulics, mechanics) and combined into one
single chamber - either fixed or mobile.
Ozone uses only quality corona discharge technologies. We
never use UV methods as they are unreliable and only treat a
narrow range of pollutants. Compared to chemicals, ozone
is a stronger microbe killer, is cheaper, requires no hazardous
consumables, and leaves no residue. Join the ozone revolution
and protect your food investment.

 

Modular Purifier PE2

The PE2 is designed for the food industry. It includes a wide
range of features:
• Plasma emitters (corona discharge).
• A nominal output of 1000 mg/hour, at a high concentration
for dissolving into water for food applications.
• Extra long-life, high quality design. The components have
a design life up to 10 times that of alternative products.
• Unique fully potted enclosure, electrically insulated, with
EMI certification.
For larger applications, multiple PE2's are required. The
PE2 is a modular design. These simply snap together like
"lego blocks". Multiple units can be connected togther, as
shown opposite.
The PE2 can be simply connected to a venturi kit, in a
recirculation loop around a tank (see typical configuration
below). A water pump (polymer or stainless steel) creates
the flow through the pipe and venturi. The oxygenator
accessory can be connected to the inlet of any PE2 system.
This triples the ozone output and ensures that the feedstock
air is dry and clean. The oxygenator includes an inbuilt
compressor. For example, the 2PE2 and AX8 create a
6g/hr system.


 

Fully Integrated Systems WX2

Fully integrated systems come complete with purifiers, oxy-
genators, water pump, stainless steel contact tank, venturi kit
and are skid mounted.

 

Typical Configurations

 

 

 
 

Larger Systems WA8, WX8

Larger systems provide outputs up to 150 g/hour and concentrations up to 10% by weight:
• The WA8 is fully integrated, with all modules combined into one case - ozone generator, air filters, compressor, air dyers, etc.
• The WA8 is designed to be connected to an oxygenerator or
oxygen bottles.
• The electronics are very sophisticated
with a touch pad control, PCB logic and
LCD display. This allows automatic
programming and feedback signals from
Controllers.
• Acessories include: Venturi Kit, Water
Pump, Oxygenators, Destructors, Water
Chillers, etc.

 

 

Comparisons with other technologies

The problems with using conventional chemical disinfectants:
• Require special procedures and equipment for hazardous chemica l handling, storage and transport. (Whereas ozone is produced on-site.)
• They are expensive consumables with high running costs. (Whereas ozone only uses minimal electricity).
• May not kill protozoa or certain bacteria. (Ozone kills microbes 50% stronger and 3,000 times faster than chlorine).
• Chemicals leave a residue on foodstuffs and equipment. (Ozone does not).
• Chemicals can create carcinogenic byproducts. (Ozone does not).


The problem with particulate filters:
When used alone they do not remove the following:
- bacteria and viruses - organic contaminants
- chlorine, fluoride - minerals and they must be replaced regularly, e.g. 6 monthly.

 

 

 

The problems with ultraviolet products (radiation type):
When used correctly they can kill microbes, but they have no effect on other pollut ants such as:
- organic contaminants - off-tastes
- minerals - off-colours
- chlorine - salts and scale.


Their ability to kill microbes reduces dramatically:
- if there is organic load or sediment in the water, which shields the microbes from UV rays
- if the UV tubes are not regularly cleaned
- if the water flow rate is too high.
The UV tubes break easily.
The UV radiation is carcinogenic if it escapes from the chamber.

The problem with carbon filters:
When used alone they do not remove the following:
- bacteria and viruses - fluoride
- dissolved ions - minerals
and they are easily colonised by bacteria. They must be replaced regularly or pollutants just pass straight through them.
Particulate Filters + Carbon + Ozone can solve these problems.

 
 

Controllers

A large range of Controllers is available for measuring ozone concentrations in the gas phase or liquid phase. Manual "wet chemistry" sets are available for cost effective measurements whilst sophisticated electronics control the whole system.

 

 

 

 

Oztec Service

Ozone provides extensive documentation to assist customers
(and Distributors). Customers can fill out a "Fact Finder"
document to help size up the job. Ozone can then generate
a Sizing Report by reference to Oztec - a computer database
which records our extensive experience and research with
water treatment for the food industry. We can also generate
Component Lists and Layout Drawings as required. The
products themselves include extensive Instruction Manuals.
