In Municipal Water Treatment
Plants, chlorine has been the only general
disinfectant used so far. This has changed in the
last few decades as almost all the municipal water
treatment plants have gone in for ozone as the
primary disinfectant. While chlorine produces
carcinogenic chloro by-products, ozone does not
produce any harmful by-products as a result of
ozonation. Ozone is used as a primary disinfection
to take care of the disinfection in the primary
stage. New Municipal water treatment goals for DBPs disinfectant Byproducts & for microbial inactivation will increase the need to new disinfection technologies. Ozone is an attractive alternative. |

Advantages of the Ozonation
System:
• Ozone is effect over a wide pH
range and rapidly reacts with bacteria, viruses, and
protozoan’s and has stronger germicidal properties
then chlorination. Has a very strong oxidizing power
with a short reaction time.
• Does not require the on-site storage of other
chemicals with the associated hazards and costs.
• Reduces the amount of chlorine required to
maintain a residual in the distribution system
• Ozonation can reduce the chemicals needed for
flocculation or flotation by 20-50% while improving
filter performance due to micro flocculation
effect.
• Ozonation provides no germicidal or disinfection
residual to inhibit or prevent regrowth.
• Reduces the formation of disinfection by
products (DBPs) such as TTHM and HAA5.
• Ozone will oxidize both organic and inorganic
substances, remove unwanted taste, odor and color,
and provide effective disinfection.
• Ozone inactivates and destroys all bacteria, virus
and protozoa’s.
