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
