Salt water chlorination
What is salt water chlorination?
Salt water chlorination is a treatment method in which chlorine is obtained directly from the water to be treated thanks to an electrolytic process. This technique avoids the use of added chemical products and is especially adapted to the treatment of swimming pool water, providing numerous advantages over conventional chlorination. In particular, the water treated with salt chlorination is of superior quality and has a characteristic transparency. The system works automatically and avoids the purchase and handling of chlorine products.
How does it work?
The system generates chemically pure chlorine, Cl2, from the chlorides present in the water through an electrolysis process. This transformation takes place in an electrolytic cell that is installed directly in the pool's circulation system. The chlorine in the cell is present at very high concentrations, immediately triggering a highly efficient disinfection process. Once this disinfection process is complete, the chlorine changes back into salt in the pool, completing a renewable chemical cycle. While fresh water always contains a certain amount of naturally occurring chlorides, to make the electrolytic process more efficient, the chloride content is increased by adding common salt to the pool. The salt concentration required is very low, it is not consumed in the process and provides one of the most widely appreciated advantages of salt electrochlorination: the water remains in osmotic balance with the skin and the eyes. This balance stops your skin feel dry after swimming and avoids the discomfort caused when opening your eyes under water. The slight saline character of the water also gives it an antiseptic effect. Unlike the chlorine supplied in different formulations, the chlorine produced by a salt water chlorinator is pure and, therefore, much more powerful. It does not contain additives or preservatives, it does not generate harmful by-products in the container and it does not degrade when stored. All this results in an extremely effective treatment and especially crystalline water, free from accumulated chemicals. The system also avoids the handling, transport and storage of hypochlorite and the associated costs. Pure chlorine is generated in a renewable chemical process in which no product is consumed. The chlorides in the salt are converted to chlorine in the cell and, after the disinfection process, turn back into salt again in the pool. The only maintenance required is to replace the cell electrodes every few seasons due to wear.
