How does Ozone work?
Ozone is made artificially by passing oxygen through ultraviolet light or a “cold” electrical discharge which causes oxygen molecules (O2) to split apart in a process called photolysis. Ozone is a triatomic molecule consisting of three oxygen atoms, which occurs naturally in the stratosphere and benefits both plants and animals by preventing damaging ultraviolet light from reaching the Earth’s surface.When one of the freed atoms collides with another O2 molecule, it joins up forming ozone (O3). Ozone readily gives up one atom of oxygen resulting in a powerful oxidizing agent that is toxic to most waterborne organisms and decays to ordinary oxygen in less than an hour in atmospheric conditions. Ozone is also a very strong, broad spectrum disinfectant that is an effective method to inactivate harmful protozoa and also works well against almost all other pathogens. Ozone is used by many municipal drinking water systems to kill bacteria instead of the more common chlorine. Ozonization is a preferred solution for killing microorganisms in water because it leaves no residue in the water after treatment and has the additional advantages of high oxidation potential, fewer dangerous by-products and the absence of taste and odor problems associated with chlorination. To use ozone as a disinfectant, it must be created on-site and added to the water by bubble contact. Ozone has many other industrial and consumer oxidation. Ozone is used to:
- Manufacture chemical compounds via chemical synthesis
- Clean and bleach fabrics
- Assist in processing plastics
- Age rubber samples to determine the useful life of a batch of rubber
- Eradicate water borne parasites in surface water treatment plants
- Detoxify cyanide wastes to carbon dioxide from gold and silver mining
- Kill or neutralize all bacteria in operating rooms between surgeries
- Disinfect laundry in hospitals, food factories and care homes facilities
- Deodorize air and objects, such as after a fire or during fabric restoration
- Kill bacteria on food or on contact surfaces
- Sanitize swimming pools and spas
- Kill insects in stored grain
- Scrub yeast and mold spores from the air in food processing plants
- Wash fresh fruits and vegetables to kill yeast, mold and bacteria
- Attack iron, arsenic, hydrogen sulfide, nitrates and complex organics in water
- Provide an aid to filtration
We are factory trained in a multitude of ozone equipment and are able to provide sales, parts as well as offer in-house or on-site repair service for all these units. The next time that you need help with ozone – information, service or assistance with a project please feel free to give us a call.
Primary Advantages to Ozone
1. Ozone is effect over a wide pH range and rapidly reacts with bacteria, viruses, and protozoans and has stronger germicidal properties then chlorination. Has a very strong oxidizing power with a short reaction time.
2.The treatment process does not add chemicals to the water.
3. Ozone can eliminate a wide variety of inorganic, organic and microbiological problems and taste and odor problems. The microbiological agents include bacteria, viruses, and protozoans (such as Giardia and Cryptosporidium).
Disadvantages to Ozone
1. There are higher equipment and operational costs and it may be more difficult to find professional proficient in ozone treatment and system maintenance.
2. Ozonation provides no germicidal or disinfection residual to inhibit or prevent regrowth.
3. Ozonation by-products are still being evaluated and it is possible that some by-products by be carcinogenic. These may include brominated by-products, aldehydes, ketones, and carboxylic acids. This is one reason that the post-filtration system may include an activate carbon filter.
4.The system may require pretreatment for hardness reduction or the additional of polyphosphate to prevent the formation of carbonate scale.
5.Ozone is less soluble in water, compared to chlorine, and, therefore, special mixing techniques are needed.
6.Potential fire hazards and toxicity issues associated with ozone generation.
