Drinking Water Treatment

In the course of the past two decades, Drinking water treatment technology has advanced under the combined influence of three simultaneously occurring factors:

• A steady increase in the pollution of natural waters
• A continued enhancement of the sensitivity and accuracy of ana- lytical methods.
• A continual raising of drinking water standards.

New 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 Ozonation :

• 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.
