Anybody entering a swimming pool contaminates the water either from secretion or just from washing off.
Typical contaminated are

• Sweat
• Skin Flaks
• Mucous
• Hair Ointments
• Urine

In addition there are contaminants and organisms from the environment of the swimming pools such as dust algae and microorganisms therefore the pool water has to be constantly filtered and disinfected.

• Bacteria kill rate is up to three thousand times faster.
• 50% stronger oxidizer than chlorine.
• Reduces traditional chemical use between 60% - 90% .
• Reduce handling and storage of unsafe chemicals.
• Reduce constant purchasing of harmful chemicals.
• Eliminate red, irritated eyes and dry, itchy skin.
• Eliminate costly replacement of faded swimwear.
• Remove unpleasant chlorine / chloramine odours.
• 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.
• Water consumption can be decreased, because of an increase in water quality.

Some of the advantages and disadvantages of ozone and chlorine used for swimming pool water purification are:

• Chlorine is not only highly toxic, it is a poisonous gas
• Although ozone is rated as toxic at the 1.0 mg/1 level by the United States government, no one has ever been known to have died as a result of inhaling it. Ozone has a very pungent odor, noticeable at the 0.01mg/1 level; is highly irritating at elevated levels; tends to dry out the skin and mucous membrane and can cause temporary throat discomfort.
• Chlorine is stored in high pressure containers on the premises and can be dangerous. A broken chlorine line could cause serious problems.
• Ozone is generated on the premises (not stored)
• Chlorine, when mixed with urine and perspiration, will form chloramines that will cause eye irritation and are toxic to aquatic life.
• The cost of chlorine is constantly increasing and has become quite expensive. Ozone, on the contrary, is becoming less expensive due to the increase in efficiency and lower energy consumption. The overall cost of using ozone instead of chlorine will be less costly to the pool owner.
• Ozone is the most active oxidizing agent that can be used with safety. It is sometimes called “activated oxygen”.
• Tests have proven that ozone is from 600 to 3000 times more active in the destruction of bacteria and viruses than chlorine in the same concentration. Escherichia Coliform (E. coli) is killed within 5 seconds by ozone at a concentration of 1 mg/1, whereas 15,000 seconds for the same results using chlorine at the same concentration.
• Ozone is effective against mustiness, mildew, fungus and can be used to eliminate the “locker room” odor in dressing rooms.
• Due to the flocculation process and the ozonation process, the water in an ozonated pool is very clear. A sky blue color is imparted in the pool water.
• Chlorine is more effective against algae growth. Outdoor pools using ozone have a problem with algae bloom, under high temperature conditions, that can be eliminated bu chlorine “ shock treatment’ of 5 to 10 mg /1, when needed.
• Chlorine needs pH control (7.0 to 7.4 pH) for reliable results. Ozone does not not require pH control but some of the other chemicals used may require such control.
• Ozone is an excellent deodorizing agent for many substances, such as putrefactions, hydrogen sulfide, urine, smoke, cooking, paints, etc.
• Ozonated pools do not have the “bath tub ring” that is caused by skin oils, grease, ointments, hair dressing and cosmetics used by the swimmers
• Ozone is used in therapeutic pools and baths for the treatment of skin infection and burns.

Ozone as a cooling tower biocide is not only environmentally benign, it also brings a significant number of other benefits.

The circulating water of cooling tower systems has always been an ideal place for growth of microorganisms. The warm temperature of the water and the addition of nutrients from the scrubbed air flowing through the tower provide a virtual nirvana for all sorts of microbes and algae. In turn, these organisms multiply at fantastic rates. The result is degraded system efficiency due to blockage of flow, shortened equipment life due to corrosion, increased operating cost due to higher pumping power requirements, and the spread of disease or even death.

Ozone as a cooling tower biocide offers a means to this end. It is not only environmentally benign, but ozone use also brings a significant number of other benefits to the cooling tower system operator. Ozone is a practical oxidizing biocide because it is the fastest acting and the most efficient oxidizing agent against all microbiological organisms - when properly applied, ozone will kill all viruses, bacterium, cysts, and algal species. And, any ozone not consumed as a biocide naturally decays to oxygen, making ozonation the preferred choice for biological control of many cooling tower systems.

Field tests have demonstrated that the use of ozone in place of chemical treatment can reduce the need for blowdown, and, in some cases where make-up water and ambient air are relatively clean, can eliminate it. As a result, cost savings accrue from decreased chemical and water use requirements and from a reduction of wastewater volume. There are also environmental benefits as fewer chlorine or chlorinated compounds and other chemicals are discharged. There is also a belief within the industry (and some evidence) that under certain conditions ozone acts as a descaling agent. The premise is that ozone oxidizes the biofilm that serves as a binding agent adhering scale to heat exchange surfaces. When scale buildup on condenser tubes is reduced, higher heat transfer rates are achieved. Increasing the condenser heat transfer rate will reduce the chiller head pressure, which then allows the chiller to operate more efficiently and consume less energy.  

Biological growth, scaling, and corrosion are the main maintenance concerns with these cooling towers.

• Will not load any substance in water unlike chlorine which builds up the TDS till the cooling power is lost.
• Virtually eliminate the necessity for the blow down.
• Saves you from the 'who-pollutes-pay tax' which is becoming standard world wide (people are made to pay according to the load they dump even in the permitted drains)
• Makes the water crystal clear, eliminating all turbidity.
• Removes all bacteria, including the dreaded 'Legionella'.
• Costs almost nothing, once installed. Just a little power…
• Dissolves the scale and inhibits further scaling, hence improving heat transfer and further saving on chemicals and pollution.
• Decreases the corrosion by 50% (acts by passivation like chromates which are used as corrosion inhibitors, but dangerous)
• Removes froth  and  does not generate further froth.
• Brings the bacteria count down to below 1000CFU/ml compared to 10⁵ to 10⁷ for chlorine
• Makes you free from the suppliers of chemicals and maintenance personal as well.
• Reduced Chemical Usage – Chlorine can substitute for several chemicals in a cooling tower treatment package, reducing and possibly eliminating the use of such chemicals..
• Increases dramatically Heat Transfer Efficiency.
• Repays for its capital cost in 6 to 18 months.
• After this, it adds good money to the bottom line of your clients, balance sheet. . . and yours by their repeated orders.
