What are disadvantages of ozone?
When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
What is ozone treatment?
Ozone may be recommended as a pretreatment to control biofouling of reverse osmosis membranes and ion exchange resin, as certain membranes and resins are degraded by chlorine. Ozone treatment units are installed as a point-of-entry treatment system. At the point where the ozone mixes with the water, turbulence and bubbles are created;
How does ozone work?
How ozone treatment works. Ozone is an unstable form of pure oxygen. Like chlorine, ozone is a strong oxidizing agent and is used in much the same way – to kill disease-causing bacteria and viruses. Ozone may not kill large cysts and some other large organisms, so these should be eliminated by filtering or other procedures prior to ozone treatment.
Where is treated water stored?
Some systems store treated water in a contact chamber to assure that water is continuously treated until used. Ozone treatment systems frequently have pre-treatment and post-treatment devices.
What is the effect of pH on ozone?
Ozone has been found to be effective over a wide range of pH, but a pH slightly above 7 increases treatment efficiency. The ozone demand is related to the level of contamination in the water. When substances in the untreated water react with ozone, ...
Do ozone systems need maintenance?
Most ozone systems do not require extensive maintenance. Some systems use an air-drying material, which needs to be replaced periodically. It is also necessary to periodically clean the water storage tank and check pumps, fans and valves for damage and wear.
What is activated carbon?
Activated carbon is a common post-treatment device for removing partially oxidized organic material. Most people can smell ozone at a concentration of 0.01 milligrams per liter (well below the level for general comfort) and breathing traces of ozone for a few minutes is of little health concern.
Do UV lamps need to be replaced?
If UV radiation generates the ozone, the lamp must be replaced periodically . Any pre-treatment or post-treatment devices may require additional maintenance. In addition, the entire system should be routinely inspected by a water treatment specialist for any ozone leaks.
Why is ozone used in water treatment?

Is ozone a disinfectant?
Therefore ozone is less suitable for residual disinfection and can be used only in particular cases (mainly in short distribution systems). Chlorine and chlorine dioxide often replace ozone as a final disinfectant.
Is ozone good for oxidation?
Several surveys show that ozone can be very effective for the oxidation of several pesticides. At a water treatment plant in Zevenbergen (Holland) it was proved that three barriers (storage–ozonation–granular active carbon filter (GAC filter)) are effective and safe enough for the removal of pesticides.
Is organic matter biodegradable?
Organic matter is partly oxidized and becoming more easily biodegradable. This results in a higher amount of BDOC (Biodegradable DOC). As a result, ozone improves the removal process of NOM by a subsequent filter, when it is used as a pre-oxidant [33,39,40].
