Comparison of Ozone and UV
Comparison of Ozone VS UV in Water
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. |
