The filtration

Swimming Naiades will advise you to design a closet that will be grouped filters, pumps and analyzed.

There are 3 ways to filter for clean water.

	Sand filtration: the most used method today and long ago. Water is drawn from the pool into the equipment room by a pool pump. Once in the machine room, water passes into the filter pool. This filter consists of two superimposed coushes sand in which impurities are found prisionnières Vons. The water exits through strainers situiées bottom of the filter and the water off again and the pool. The advantage of this method is its ease of use particularly in terms of cleaning the filter. Just place the 6 way valve into the wash cycle, and water passes through the filter in opposite way: it first passes through the strainer bottom, passes into the sand and takes it well with dirt, leaves through top of the filter and the dirty water then goes down the drain.
	Cartridge filter: this method is in fact constituted by a cartridge which is placed vertically: the water comes on one side and the other spring. The cartridge may be made of paper for example and consisting of a large set of folds. The impurities remain trapped in the folds. The advantage of this method is higher than the fineness of filtration sand filtered. However, the drawback is cleaning the filter, you must remove the cartridge and then clean the jet.
	Diatomaceous filter: this system is very lmoin the most efficient with an extraordinary degree of filtration. The filter is composed of diatoms (fossilized algae powder). The use of diatomaceous filter guarantees a filtration can not be found elsewhere. By cons, level Default: this system is very sensitive and must use a very special way. Unlike the sand filter must be changed regularly diatoms.

The Treatment of pool water

The treatment complements the filtration system that can not filter everything. It will remove faloir bactéties, viruses and algae. Many techniques exist. Your specialist Naiads Pool of France will advise you on the best treatment to put in place depending on the use you made of your pool.

The water balance:

Ensure a clean and healthy water goes through filtration and chemical treatment of your pool. Physical and chemical actions are essential to fight against the many pollution.
There are three indicators used to measure the water balance:
* The potential hydrogen (pH)
* Alkalinity (TAC)
* The water hardness (TH).

Treatment of water by UV

If you do not want to handle chemicals too frequently or, simply, you have something else to do, you may be tempted by an automatic disinfection system. Technology of UV treatment is now Best solution to not handle the chemicals.

The ultraviolet disinfectors to enable automatic disinfection of your pool water. No need to use chemicals and that is why this green solution is back. Indeed, the concept is not new but the prices were previously inaccessible. Now, the technical and ramps UV tubes of reasonable size make the principle effective, practical, environmentally and economically.

Chemical treatment:

Chemical treatment is the most radical solution to find clear water. It quickly eliminates pathogens and organic waste.

There are three chemical treatments:

Chlorine treatment

Salt treatment

Bromine treatment

Chlorine is widely used in the chemical treatment of pool. To the point that the smell of chlorine is associated with the pool. The higher the pH of your pool water, the lower the action of chlorine is effective. However, chlorine is never 100 percent effective because it would require an overly acidic pH that swimmers can not afford.

Is used more generally stabilized organic chlorine in the form of pebbles, pellets or granules dissolve quickly and very fast.

Chlorine contains a stabilizing effective against UV rays, it is undoubtedly a plus. However, these stabilizers are accumulating in the water while chlorine has a tendency to degrade over time. So, it reduces the action of chlorine. Therefore, the pool water must be changed at third when chlorine is present enough. This is the only way to decentralize water.

There are also free chlorine stabilizer for intensive treatments such as calcium hypochlorite (for freshwater) and lithium hypochlorite (fits all waters).

This type of treatment allows a continuous action without the need for regular human intervention. Just insert in your pond salt. It will then be converted into sodium hypochlorite (chlorine) by electrolysis. Once transformed into salt chlorine finished "work", it becomes salt which can be further processed after further electrolysis.

The problem is that the water filtration, wintering, washing the filter or simply the renewal of water change the concentration of salt. That is why we must think of adding salt from time to time.

The clear advantage of treatment by electrolysis of salt is that chlorine is constantly renewed. This limits the formation of chloramines and smells that go with ...

Bromine is quite similar to chlorine. Its effectiveness is not to question because it proves effective against fungi, viruses, bacteria and organic waste in water. Bromine is compatible with all types of pool. Its natural components (from seawater) are not fragrant. In short, bromine has many advantages over chlorine, except maybe the price!

Bromine is sold in the form of fast dissolving tablets that are placed in the skimmer, and then, in the form of slow dissolving tablets that are placed on the filter circuit. More your pool is large, and it will be expensive to perform a chemical treatment with bromine.
