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.
