A pool is an artificial pond intended for bathing and sports such as swimming. The word was originally used to designate wells for freshwater or saltwater. It was also used to designate water tanks connected to the water supply. The early Christians used the word pool to designate the font. Indeed, before the invention of the treatment plants in pools, bathrooms or decorative, outdoor fish are used to clean water, as insect larvae ate, and hence the name (pool demolition Los Angeles).
In the care of the pools water chlorine is necessary to take into account a number of parameters. Normal range in a pools. Percentage of free chlorine 0.90 - 1.50 mg / L (1.5 to 2.0 ppm). The chlorine can be added directly or produced by hydrolysis of salts. Salinity 4 g / L (4 kg / cubic meters) Occasionally, the supply of salt may be required. PH 7.2 to 7.6 (ideally 7.2 to 7.4) can be reduced by adding acid, and increased by the addition of a base (pH +), such as sodium bicarbonate, NaHCO3 formula.
There are also several modalities, such as fixed, portable and removable. In sports world we can distinguish three types of pools. Today's pools have experienced significant technological advancement, especially in terms of water purification and sanitation.
Water is clean and transparent. It is done by recirculating water through a suitable filter. The filter is usually a thick layer of sand contained in a reservoir provided the size of pools. A pump passes water through the filter, which retains the impurities that may be in it. The dirty water can be of three types, and each has a system to remove.
An average person, about 70 kg mass, displaces about 65 liters of water; 100 6500 liters (6.5 m3), which normally go down the drain for the overflow. When there are no swimmers must be replenished with water from the mains. Pera help, provision provided tanks to hold water and reintroduce it when the pool is empty of swimmers.
Other developments include accessibility (lifts, obstruction lighting, tiles textured plates Braille, hearing terminals, etc.) 1. The use of renewable energy and rainwater harvesting should grow by 2020. Stainless steel basins, considered more hygienic appear (Chartres, Quiberon, or Herlies Bellerive-sur-Allier, or Sinnamary in Guyana (in 2009).
The filter requires periodic cleaning is achieved by circulating the water in the opposite direction to filter for a while, the water should go to the drainage system. This is to prevent microbes thrive in water or fungi that may be harmful to swimmers. Chloro derivatives are employed, the pH is controlled and sometimes even water temperature. New needs arise.
The creation in 1855 by Germany, public showers tends to disappear from the public baths notion pools. In Roaring Twenties (1920-1930), F will begin construction of twenty public pools highlighting a notion of play, sports and fun, as part of the euphoria of the post-years war. In 1924, the first born only pool designed for swimming and playing and finally splitting the concept of hygiene that of pleasure.
