Municipal Water Treatment

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.
