ULTRA VIOLET (UV)

OZONE

The energy is not enough to destroy all types of bacteria, virus, protozoa, and fungus.

Mercilessly kills all bacteria and virus.

Requires more contact time as the UV rays is stationery & hence water has to be exposed to it for a longer time.

The reaction is instantaneous as the gas mixes with water. The reaction rate is 3,200 times faster than any known method.

If the water is turbid & has high level of suspended solids, the penetration of the rays is not deep.

Reduces turbidity and the suspended dissolved solids do not make any difference.

Scale forms on the tube thereby reducing the disinfections rate.

Disinfections rate is constant and there is no scale formation.

Cannot eliminate algae & biofilms.

Eliminates algae & biofilms.

Cannot kill SPORES of bacteria & virus.

Eliminates even SPORES.

Does not act as flocculent.

Act as flocculent.

Does not eliminate ODOR.

Eliminates ODOR.

Does not eliminate COLOUR.

Eliminates COLOUR.

Cannot treat waste water.

Treats any type of water.

UV light cannot increase or decrease energy 

Ozone can be increased or decrease to to desired level for effective treatment of water

The Intensity of the bulbs start reducing

Intensity can not waver once fixed.

Has very narrow application (Bacteria elimination only)

Has wide applications like eliminating bacteria, odor, color, treating waste water, effluent & so on

UV intensity can not be measured 

 Ozone presence can be felt.

Can not stop corrosion.

Stops corrosion completely 

Can not store as SPORES will breed and bacteria will come alive.

Treatment is permanent.

Bulbs get fused often

 No bulbs  involved

Needs maintenance

No maintenance required

Has no effect on compounds

Oxidizes the compounds.
