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 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. |
