The CDC recommends maintaining a free chlorine concentration of at least 1 part per million in swimming pools, and at least 3 ppm in hot tubs. Pools should also strive for a pH of 7.2 to 7.8 ...
When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7.2 to 7.8 – according to the Langelier Saturation Index, or 7.8 to 8.2 – according to the Hamilton Index; higher pH drastically reduces the sanitizing power of the chlorine due to reduced oxidation-reduction potential (ORP), while lower ...
A lot of people (understandably) have questions about how the virus may or may not spread while they’re splashing around.
As an alternative to shock chlorination, some swimming pools are chlorinated by use of a chlorine-generating filter that electrolyzes common salt. Pools chlorinated by this method generally have lower levels of chlorine than directly chlorinated pools. Such pools are called saltwater pools. [citation needed]
In addition, trichloramine has been detected in the air above swimming pools, [6] and it is suspected in the increased asthma observed in elite swimmers. Trichloramine is formed by the reaction of urea (from urine and sweat) with chlorine and gives the indoor swimming pool its distinctive odor.
While chlorine kills most bacteria such as E. Coli in less than a minute, it takes at least 16 minutes to kill Hepatitis A, and the Cryptosporidium parasite can last in the swimming pool for over ...
Shock chlorination is a process used in many swimming pools, water wells, springs, and other water sources to reduce the bacterial and algal residue in the water. Shock chlorination is performed by mixing a large amount of sodium hypochlorite, which can be in the form of a powder or a liquid such as chlorine bleach, into the water.
A shortage of chlorine has caused at least 10 water systems to apply for assistance under the EPA's Safe Drinking Water Act for the first time ever.
