OZONE APPLICATIONS

OZONE APPLICATIONS

Community Drinking water :

Ozone is rapidly gaining popularities over chlorine in the disinfection of drinking water. In drinking water treatment Ozone presence not only disinfects the water but also improves the color, odor & taste of the water. It can remove dissolved metals & organic impurities & increase filter velocities. Experience has demonstrated that it destroys with extreme efficiency the spores of molds, amoebae, viruses & bacteria as well as various pathogenic & saprophytic germs. The destruction rate of germs has no measurable dependence on pH in case of OZONE. This fact constitutes one of the major advantage of OZONE over other disinfectants. Residential drinking water Ozone purifies the water by stabilizing chlorine residues, heavy metal ions, and various organic impurities that cause unpleasant smells, making tap water undrinkable. As a result, ozone water used in coffee or tea, will taste better. This is the same purification process used by bottled water companies (packaged drinking water). Ozone has higher oxidation potential than commonly used sanitizers. It can literally oxidize material in water 3200 times faster than chlorine & 5600 times

faster than Bromine. Vegetables & fruits if washed in ozonated water stay fresh longer & even taste better.

Swimming pool :

The concept of treating Swimming Pool Water IS THAT THE WATER IS PURIFIED AND DISINFECTED. Ozone is the most powerful oxidant used in swimming pool water treatment

today and has the ability to destroy algae, bacteria, inactivate viruses and to oxidize many organic and inorganic contaminants present in waters more efficiently and more rapidly than does chlorine. Ozone as a dominating disinfectant, is not only efficient in reconditioning bathing water due to the destruction of spores and viruses, as well as the decomposition of human urine, but its use brings economies owing to a reduction in the demand for make-up water.

Cooling Tower :

INDOZ system of corrosion inhibition uses ozone technology within cooling tower systems. The passivation of the metal surfaces by ozone, plus the threshold raising effect of ozone to control scale formation, corrosion & organic growths. Simultaneously the system produces safe & non-toxic conditions within the cooling tower & aerosol water passing from the system. In part, the relies on the destruction of organic binding matter such as slimes, algae etc. to form heat transfer reducing scales & deposits. Ozone breaks down all these organic impurities to harmless by-products. Thus, Ozone eliminates all organic binder, which would otherwise aggregate insoluble matter. Control of organisms such as Legionella is significantly achieved when ozone is supplied in correct quantities, so that only very low levels (if any) of infestation occur. The risks of exposure to Legionnaires disease in aerosol emissions from the cooling tower & the wastewater from the cooling water system is considerably reduced.

Packaged drinking water plant

Only ozone is used for disinfection in Packaged drinking water plant. Because the ozone disinfection process does not cause any odors or tastes, the plastic water bottles can keep the water clean after the bottle is sealed. Ozone technology also is used in water-bottling laboratories in special plastic containers.

Waste water / Sewage treatment

Ozone (O3) is a strong oxidizer and can be particularly effective for cleaning aqueous waste streams. It is sometimes used as a pretreatment method, or to disinfect wastewater after biological treatment. It oxidizes a wide range of organics, (i.e. it can destroy cyanide wastes and phenolic compounds, and is faster acting than alkaline chlorination.) Plus, unlike chlorine, ozone doesn’t generate toxic ions in the oxidation process. Oxidation and volatilization of organics, Control of algae and associated compounds, Destabilization (micro-flocculation) of certain types of turbidity, Removal of color-causing compounds, Oxidation of iron and manganese, Very short disinfection times, and Partial oxidation of organics for subsequent removal by microorganisms. Ozonation elevates the dissolved oxygen (DO) concentration of the effluent. The increase in DO can eliminate the need for reaeration and also raise the level of DO in the receiving stream.
