Chlorination of swimming pools with sea water is increasingly used, especially in the United States. However, it is not the same river in Europe and Australia. This article describes the water chemistry, how it works and how it compares with injections of liquid chlorine, which is still mainly used the system outside of the United States. One of the questions we are asked most often, this, "Can I change the automatic chlorination saltwater in my pool?" Our answer is always - yes,But it might be the best solution. But most of all - How does it work?
More than 150 to 180 kg of water softener salt in the pool type when compiled for the first time that a minimum level of about 3000 parts per million of salt in the pool. Salt makes the water conductive so that current flow between the plates described in the cell. If the salt level is too low, then the chlorine production anymore. Salt is the only raw material from which theChlorine is generated. In the filtration steps on two electrodes in a small (usually translucent) unit cell after the filter and pool pump house heating down - to avoid excessive corrosion of these devices. The controller is a device that sends power to the cell salt. The device controls the amount of chlorine is by regulating how long the force is applied to the cell produces. When the knob is turned, the unit shall be considered in the cell for less time, soless chlorine. The control unit is often a sense of the level of salt in the pool and show the need to add more salt. Self-cleaning units have a function in the unit that reverses the polarity of the voltage across the cell, helping to clean the lime deposits from any of the panels made of cells. For the chemists among you, this is the equation and HOCl + NaCl + 2H2O = 2H2 + NaOH What does this mean? - On the left we have the salt + water - and some electrical current in a cell that does notnadgery little '!
On the right side of the equation we have the chemical HOCl, hypochlorous acid that kills all germs and bacteria. However, caustic soda and hydrogen are also produced in addition to HOCl. Sodium hydroxide (caustic soda, or as is more often called) increases the pH of the water bath. Why is salt water chlorination and pH adjustment with measurement, which will cater to the need to continuously measure the pH and add it to installAcid into the pool to keep it in the correct range. A swimming pool is too acidic to eat the tiles and Malta as well as the heat pump and thoroughly unpleasant to swim in
Hydrogen, which is also produced is usually lost only in the atmosphere. But oxygen can also be a byproduct of the cell when the water molecules into hydrogen and oxygen, there were several explosions in the United States, if the cell is defective and produces monster conditions have been met.
There are a lot of otherDisadvantages of using salt water and chlorine is very harmful to the environment - but please read my other article about Salt Water Chlorination, learn more.
The main disadvantage of chlorination saltwater that are very vulnerable in areas with hard water, the cells for the formation of deposits of calcium carbonate. The electronic boxes that come with the system, change the polarity of the probes in cells to reduce, but at regular intervals, the cell must be considered asapart and clean - a job is just completely bad. This should not be a problem in fresh water - but we have many of them in France! In Europe, fully automatic injection liquid chlorine and pH control for about the same price can be installed. Both systems are very reliable - but to create a little 'more complicated. But they have control of the chlorine and pH levels very closely and will last until the pool with the exchange of certain shares. The procedure is quiteSalt water chlorination similar in that there are some small in-line cells with which all the water in the pool in about 6 to 8 hours has passed. Be measured as the water flows through the first cell pH and chlorine levels, in particular the pH by adding acid or caustic soda and then set the liquid chlorine is injected once per second on a decrease in the cell. All these parts and the whole system are usually very reliable and can last for 10 years or morewithout attention.
So live in Europe and Australia, more professional pool installers to their customers automatic injection of chlorine, because it is more reliable and cheaper. Saltwater chlorination is also very unfriendly to the environment, but read my other articles to learn more about it. For more information follow this link Pools in France.
