What is water?
Water is composed of various elements (calcium, magnesium, sodium, sulfate, etc.) that strive to maintain a balance.
In the case of a swimming pool, this balance is disrupted by certain factors:
Organic waste brought in by swimmers (sweat, saliva, urine, cosmetics, sunscreen, etc.) and from the outside environment (dust, pollen, insects, leaves, etc.). All of this waste serves as the primary food source for microorganisms.
Micro organisms : algae, moss, bacteria, mushrooms, viruses… For this reason, swimming pool water that is not maintained will stagnate (green or cloudy water, development of algae, etc). This is a visual result and indication of the development of micro organisms.

Water is made up of multiple elements (calcium, magnesium, sodium, sulphate…) which try to remain in balance. In a swimming pool, this balance will be upset by various factors:
Organic waste brought by swimmers (sweat, perspiration, saliva, urine, beauty products, sun cream, etc) and other wastes coming from the outside environment (dust, pollen, insects, leaves, etc). All of this waste is the food of micro organisms.

The importance of filtration
Filtration circulates the pool water and removes solid impurities that settle in it. Properly sized filtration (pump flow rate, filter size, etc.) is essential. This initial treatment accounts for about 80% of the effectiveness of pool maintenance.
Therefore, the filtration time must be proportional to the temperature.
The higher the temperature, the longer the filtration time. The following table helps determine the appropriate filtration time. Filtered water looks clean and pleasant, but it is not free of invisible particles. Even the best filtration cannot eliminate microorganisms: algae, bacteria, viruses, fungi, etc.
Pool water therefore requires additional treatment: disinfection.

Water Disinfection
Disinfection removes microorganisms (algae, bacteria, viruses, fungi, etc.) from the pool.
The resulting water is safe and suitable for swimming. Disinfection can be performed:
Automatic disinfection
Automatic systems have the advantage of providing continuous treatment without user intervention. The advantage of salt electrolysis over other systems is that it produces the most effective disinfectant available: chlorine.
Chlorine offers a dual benefit. It provides water that is both disinfected (curative action) and disinfecting (preventive action). Other processes (UV, ozone, Cu/Ag ionization, etc.) provide only curative disinfection. In the case of a swimming pool, these treatment systems therefore require an additional chemical to make the pool water disinfecting.

Water balance
depends on three factors
The balance of these three parameters is essential to the swimming pool water quality as well as to the performance and lifetime of swimming pool equipment. Water that is too soft will be aggressive and corrosive to the equipment (filters, pumps, pipes, etc). Hard water, on the other hand, will deposit scale on the pipes, on the swimming pool lining and in the sand filters. These three elements can be balanced using the Taylor scale.
Hard water and polarity inversion
From 20° of total hardness (TH), water is considered as hard.
This is often the case in France where two thirds of the ground is limestone based. Hard water causes considerable scaling of the chlorination cell. This implies regular checks and tedious cleaning.
To overcome this problem, POOL TECHNOLOGIE has equipped all of its chlorinators with polarity reversal.
Polarity inversion allows to clean automatically the chlorination cell (every four or six hours depending on the model). POOL TECHNOLOGIE has taken one step further: to adapt the regularity of polarity reversal to the water in your swimming pool,some models feature an adjustable polarity reversal frequency from 0 to 24 hours. The harder the water,the higher the inversion frequency must be.
The greater the hardness of the water, the greater the reversal frequency should be. The adjustment must be done carefully: the reversal frequency has an affect on the cell lifespan.
