The pool water

The pool water is a living environment that is constantly evolving and rapidly depending on temperature, time, pollution from the environment (pollen, insects, plants ...), number of bathers (A clean body pollutes up 6 m3 of water), sun creams, etc ...(Chlorinator repairs)

The pH is part of the analysis of water (with the analysis of disinfectant rate) and it must be measured regularly. This is one of the first stages of water treatment.

What is PH? What is the ideal pH for my pool? Why maintain an ideal pH? What can vary the pH? How to measure the pH? Correcting the pH?


pH definition

PH, or hydrogen potential , represents the concentration of hydrogen ions in the water. It determines whether the water is acidic or basic. Its value can be between 1 and 14.
A pH of 7 is equivalent to a neutral water
A pH greater than 7 is equivalent to a water is alkaline or basic
A pH less than 7 is equivalent to an acid water(pump repairs)


What is the ideal pH for my pool?



Namely : The pH of the water balance is determined on the day of filling the pool. It is then stable. It must then be maintained if it is between 7.2 and 7.6.
If at the base, your water is too limestone (pH = 7.8, for example), it is advisable to get off this pH. But this unbalanced pH will tend to rise each day. It will therefore treat every day until the pH is rebalancing the ideal pH.


Why keep the water of the pool at an ideal pH?

Achieve an ideal level of pH is important for several reasons:


> The different processing products are more effective
Best action of disinfectants (especially chlorine)
A well balanced pH provides better maintenance of the chlorine content.(replacement cell repairs)

Optimal use of flocculants
The flocculant used for sand filters less effective when the pH rises.
Above 7.6, it is common that flocculant instead of precipitating, solubilizes: it then passes through the filter and can induce post flocculation in the basin. The water becomes cloudy.

Best algaecide
Algae proliferate more in high pH (green water, green stains on the walls).

> No damage to the equipment
Fasteners, coating, water filtration system, etc.

> Best bathing comfort (services)
The pool water is less irritating to swimmers (skin, eyes, mucous membranes) at a pH between 7.2 and 7.4.

Namely : A good pH ensures almost complete oxidation of chloramines. These latter are produced by the action of chlorine on nitrogenous materials submitted by bathers, such as sweat. They cause irritation of the eyes and respiratory tract, and is responsible for unpleasant odors.
