Ozone Applications

Bottling Water

Ozone treatment is the most frequently used disinfection process in water bottling today. With the application of a single ozone treatment step, the water bottler can disinfect the water, the bottling equipment, the bottle, the air above the water and the sealed cap of the bottle, thereby provide a most effective barrier to microbiological contamination for the protection and benefit of the consumer.

Ozone Benefits for the Beverage Market

Ozone is superior to any other disinfection method because of its high oxidation state.
Ozone allows for lower operating costs and reduces overall chemical costs.
Ozone is not typically associated with by-products, and naturally reverts to oxygen, so no taste or odor is associated after its use.
Ozone is generated on-site. Therefore no dangerous storage or handling is required.
The International Bottled Water Association (IBWA) suggests a residual ozone level of 0.2 to 0.4 ppm. This provides disinfection to both the water and the bottle.
Destroying bacteria instantly, ozone works faster than any other oxidant on the market!

These are the reasons why most water bottlers rely on ozone treatment to provide a safe, good tasting, aesthetically pleasing and storage stable product. As the ozone treatment became a well accepted, routine part of the water bottling process, many of its other benefits beyond the disinfection have become taken for granted and nearly forgotten.

Some water bottlers may not even realize today that the use of ozone also provides benefits, such as, improved taste, elimination of odour, and long 1 years storage stability.
These benefits have improved their product substantially making it a good tasting and safe.
These are the product quality features that the costumers have grown to expect and enjoy.

Since ozone treatment has become such a key process for the water bottlers, they need to stay current with the advances in the technology, and the improvements in the ozone treatment process. In addition they must follow and review the regulatory and procedural changes in BIS standards.

Swimming Pool

Improvement in quality of pool water is attained by elimination of chemical content. Swimming pool water pollution is mainly caused by swimmers. The pollutants can be divided into three groups Micro organisms, organics and solid particles.

Each swimmer carries a large number of micro organisms such as bacteria, virus which can cause disease. Organics come from urine, sweat, and saliva which contain ammonia, urea and amino acids. These react with chlorine and form chloramines which irritate the eyes and skin. Solid particles are due to skin flakes, hair and dust.

KEY BENEFITS OF USING OZONE IN SWIMMING POOLS

Bacteria kill rate is up to 3000 times faster
50% stronger oxidizer than chlorine
Reduces traditional chemical use between 80% – 90%
Reduce handling and storage of unsafe chemicals
No formation of dangerous by-products
Eliminate red, irritated eyes and dry, itchy skin
Remove unpleasant chlorine / chloramines odors
No adverse health or environmental effects
Improvement of the filter and coagulant capacities. This leads to a reduction of coagulant use and less backwashing of the filter is required

ADVANTAGES OF SWIMMING POOL OZONATION

Internationally most accepted for swimming pool application
More effectively destroys Bacteria, Viruses, Fungi, and Algae & Spores
1.33 times more powerful than chlorine
3,100 times faster than chlorine
Ozone has a micro-flocculation property
O3 destroys organism such as phenols, pesticides, herbicides & PCBs
Oxidizes inorganic such as cyanides, sulphides & nitrites
Oxidizes soluble ions & manganese
Removes Colours
Removes Odors
Reduces Turbidity
Reduces TDS
Operates bet. pH 6 to 9
No eye irritation
No skin blackening
No harmful Disinfectant Byproducts (DBPs)
If ozonated water swollen not dangerous

Waste (Backwash) water does not require any treatment

Cooling Towers

3,100 times more germicidal than chlorine
Eliminates the use of chemicals except for pH balancing
Ends discharge liabilities and chemical storage record keeping
Destroys all types of microorganisms instantly
Minimizes condenser fouling
Decomposes organic waste by oxidation
Removes existing calcium carbonate scale by destroying the biomass glue bonding agent
Ozone is produced on-site and requires no storage of dangerous chemicals
Low maintenance costs
The most environmentally friendly oxidant
No persistent chemicals or disinfectants in bleed – ozone breaks down to oxygen
Reduces the corrosion rate of metals, including copper heat exchangers
Saves on energy costs by increasing the heat transfer efficiency of the chiller
Faster Return Of Investment due to the above factors
Makes the water crystal clear, eliminating all turbidity

Key Benefits

Cooling tower water requires extensive treatment. During Cooling Tower water treatment, three main factors must be controlled.

Corrosion of pipes and heat exchanger units.
Scaling in pipes and (mainly) in heat exchangers.
Microbial growth (bacteria, algae).

Ozone Reduces Costs in the Following Ways:

Reducing makeup water to the cooling tower by permitting more cycles between blow downs
Eliminating the cost and problems in ordering, shipping, handling, storage, and disposal of regular chemicals
Reducing power consumption by keeping the chiller heat transfer efficiency high through cleaner condenser tubes
