1. INTRODUCTION
Adequate treatment of pool water for peak hygiene and comfort involves several basic steps. These operations are
essentially
filtering
,
pumping
,
chemical dosing
and
ozonation
of the pool water.
Ozone is a unique molecule with special properties making it extremely useful in water treatment for a number of reasons:
▪
It is highly oxidizing, a property that can be utilized to degrade or eliminate certain unwanted organic or inorganic
substances.
▪
It has excellent bactericidal and virucidal power.
▪
Its high disinfectant power is not affected by water pH.
▪
It is extremely easy to obtain, as it is produced on-site and requires only air and electrical power.
▪
It produces no hazardous byproduct, but simply decomposes in water to yield harmless oxygen.
As a result, ozone has a wide variety of potential applications, with ozone generators used in public and private pools,
spas and rehabilitation pools, as well as in the food industry. It can also be used to eliminate odors, a process known as
air freshening (e.g., in dressing rooms, lavatories, cold rooms, purifier equipment, etc.).
2. PRINCIPLE BEHIND AN OZONATION OPERATION
Ozone equipment works by treating part of the flow of filtered water and mixing it with ozonated air to achieve adequate
disinfection.
For proper mixing of ozonated air with water, a pressure pump and a venturi or injector will be needed
(see Figure 1).
