What is Ozone?

Ozone (O3) is a gas allotrope of oxygen. At normal temperature and pressure, it is an unstable gas that rapidly decomposes to return to its oxygen molecule (O2). Due to this characteristic, it cannot be stored or packed in a container, but must be generated on-site and used immediately.

Isn't ozone useful in drinking water treatment plant?

Yes. Ozone is a strong oxidizer agent than chlorine. Extreme effective disinfection. Kill bacteria 100%. Remove odor, color & other impurities, increase the taste of water. Most powerful than any other technology.

Isn’t ozone bad for the environment?

Ozone has a half life on the order of minutes when dissolved in water. Half life is the time it takes for half of the ozone to revert back to oxygen. Therefore, ozone must be generated on site and constantly introduced into the water to be effective.

How long does the ozone last?

As soon as ozone is formed in the generator and dispersed in a room, it will start to revert back to oxygen. This step occurs by several processes including the following: Oxidation reactions with an organic material such as odors or smoke. Reactions with bacteria etc., which again consumes ozone by oxidation reactions. Additionally ozone breaks down thermally. Higher temperatures destroy ozone quicker than lower temperatures. The ozone that remains is referred to as Residual Ozone.

"Residual" ozone created will return to oxygen usually within 30 minutes, in amounts equal to half its level. What this means is that after each subsequent 30 minute period there would be half as much residual ozone left at the end of the period as was present at the beginning of the period. In practice the half life is usually less than 30 minutes due to temperature, dust, and other contaminants in the air. Therefore, ozone, while very powerful, doesn't last long.

Will the odor come back?

No. If ozone is applied properly it destroys the source of the odor. Treatment times may vary depending on the strength of the odor but close to 99% of ozone treatments are successful.

What is the right level of ozone?

The right level is when all the generated ozone is being consumed. This only applies to continuous ozone use in occupied environments, not for shock treating. However, this is difficult to attain because it becomes a balancing act. Initially the machine's output is set high to get rid of the problem odor as quickly as possible. As this is being accomplished less ozone is required for the diminishing odor etc., thereby leaving some residual ozone in the air. If the machine output is not turned down, then more residual ozone will remain. If a strong smell of ozone is noticed, then there is more ozone present than is required. Simply decrease the rheostat (output level control). With ozone, MORE IS NOT CONSIDERED BETTER! One must be careful when using ozone in a occupied environment.

Is ozone harmful and what if any are the long term effects?

Ozone has been known for almost a century, so a great deal is known about it. Several regulatory agencies, including the Occupational Safety and Health Administration (OSHA), have stipulated that the safe allowable level of residual is 0.10-ppm (parts per million). Note that this permissible level is for continuous exposure throughout an entire 8 hour day. There is also a short-term exposure limit for ozone of 0.3ppm calculated as a 15-minute time-weighted average concentration.
The temporary affects of such a low exposure would range from headaches, to sore throats, irritation in the eyes, and nose. No long term effects have ever been documented from ozone exposure.

Q: How do I have ring around my bathtub & spots my dishes?

A: You may have HARD WATER Problem:
Hard water is characterized by spotting on dishes and glassware; scale on the inside of your water heater, plumbing pipes and other water using appliances; soap curd and ring around the bathtub; or your clothes may look gray and unclean. This is caused by an increase in calcium and magnesium in the water measuring ppm concentration.

Treatment: Water Softener, Deionization Plant

Q: My water is dirty, how do I fix it?

A: You may have a TURBIDITY Problem:
Foreign particles, dirty, or cloudy water all characterize turbidity problems in your water.
Turbidity is caused by tiny suspended particles that are the result of water main scale, silt, or other wastes. Private Wells often contain clay, dirt, or silt, which when pumped into the home is noticed as turbidity in the water system.

Treatment: Flocculation, Micron Filter, Pressure Sand Filter, Dual Media Filter

Q: Why is my dishwasher stained brown?

A: Brown or black stains found in the dishwasher are usually from high levels of manganese. Manganese that is dissolved in water can stain when the level is above .05mg/l. The dishwasher is a perfect mechanism to oxidize it because it heats it, agitates it and mixes the water with air. Manganese can also stain clothes in the washing machine, due to the same reasons. If bleach is added staining is worse.

Treatment: Water Softener, Deionization Plant

Q: Why does my water smell like rotten eggs?

A: Hydrogen sulfide gas is a naturally occurring contaminant, which gives water a disagreeable rotten egg odor or taste. This usually indicates the presence of some form of non-harmful mineral reducing bacteria in the well. Testing is very difficult because it is a gas and it comes out of solution very quickly. There are no known health effects; however hydrogen sulfide can also make the water somewhat corrosive.

Treatment: Aeration, Reverse Osmosis

Q: Why does my drinking water sometimes look cloudy?

A: Once in a while you get a glass of water, and it looks cloudy; maybe milky is a better term. After a few seconds it miraculously clears up! The cloudiness is due to tiny air bubbles in the water. Like any bubbles, the air rises to the top of the water and goes into the air, clearing up the water. The water in the pipes coming into your house might be under a bit of pressure, and gases (the air), which are dissolved in the pressurized water, will come out as the water flows into your glass, where is under normal atmospheric pressure.

Treatment: Aeration, Reverse Osmosis.

Q: Can I get rid of the yellow, brown, or rusty stains on my fixtures and my clothing?

A: You may have CLEAR WATER IRON Problem:
Clear Water Iron is characterized by yellow, brown, or rusty stains on plumbing fixtures, water-using appliances, and fabrics. Metallic taste in foods and beverages may be present. Water is generally clear when drawn from the faucet. This is caused by iron in the water supply measuring 0.3 parts per million (ppm) or higher. Clear water iron is clear when drawn from the faucet, but oxidizes when exposed to air and develops a yellow to rust color.

Treatment: Water Softener, Deionization Plant, Ozonation.

Q: I have blackish stains on my fixtures and laundry can you help?

A: You may have MANGANESE in your water:
Manganese water problems are characterized by a blackish stain on fixtures and laundry. Manganese content above 0.05 parts-per-million (ppm) causes stains. The interaction of carbon dioxide or organic matter with manganese bearing soils may cause manganese water problems. This problem is usually found in combination with iron, organic contamination, or from over chlorination.

Treatment: Water Softener, Deionization Plant, Ozonation.

Q: Why does my water taste like I have been drinking pond water?

Objectionable tastes and/or odors other than Hydrogen Sulfide can be caused by dissolved gases, organic contamination, or from over chlorination.

Treatment: Aeration, Reverse Osmosis, Ozonation, Activated Carbon Filter.

Q: I have colour in my water?

A: If you have high colour in your water it is most likely a concentration of tannins. High tannin levels are found in most surface water supplies and some groundwater or simply in waters where large quantities of vegetation have decayed.

Treatment: Activated Carbon Filter, Chlorination, Ozonation.

Q: What should I do if my water is contaminated with bacteria?

First, don't panic. Bacterial contamination is very common. Studies have found that more than 40 percent of private water supplies are contaminated with coli form bacteria. Waterborne bacteria include potentially deadly cholera and typhoid, botulism, dysentery, e-coli and more. While we know these forms of contamination can be found in tap water contamination by bacteria from water supplies.
Even though you may believe your tap water has undergone intensive water treatment, bacteria can still be present. Coli form bacteria is a commonly found, low-risk microbe, however, if found in drinking water it is a cause for concern as it indicates water bacteria levels of harmful microbes such as e-coli. Coli form bacteria may enter water supplies due to a break-down in the water treatment plant or the pipes or Sewage discharged into the water via cross contamination of sewage and water lines.

Treatment: Chemical Dosing, Ultra-Violet Treatment, Ultra filtration, Reverse Osmosis, Chlorination Ozonation
