Chlorination with doses that are deliberately selected to produce water free of combined residuals so large as to require dechlorination.
The practice of adding a sufficient amount of chlorinating compound to water to destroy chlorine demand compounds and any combined chlorine which may be present. Generally the level of chlorine added is 10 times the level of combined chlorine in the water.
the practice of adding a sufficient amount of a chlorinating compound to reduce cloudy water, slime formation, musty odors, algae and bacteria counts and/or improve the ability to maintain sanitizer residuals. (N)
is basically another term for "shocking". Refer to the listing on Shock.
See Shock Treatment and Breakpoint.
(Shock treatment) The practice of adding 5-10 times the normal daily chlorine dose to destroy algae, or to prevent problems after heavy bather loads or severe rains.
The act of heavily chlorinating, or shocking, water to oxidize undesirable compounds.
Also known as a shock treatment. Adding a significant amount of chlorine to a pool in order to oxidize unwanted organic material and provide a quick free chlorine residual.
The practice of adding extra large amounts of chlorine to oxidize ammonia, nitrogen and swimmer waste. Destroys ineffective combined chlorine.
The practice of adding an extra large dose (5-10 ppm) of chlorine to the water to destroy ammonia, nitrogen and swimmer waste which can build up in the water. This level of chlorine is required to destroy all of the combined chlorine in the water, which is called break-point chlorination. Technically it requires 7.6 moles of chlorine for each mole of ammonia to reach breakpoint chlorination. If the ratio of 7.6:1 is not reached, ammonia destruction does not happen. Common practice in the pool and spa industry is to multiply the amount of combined chlorine times 10 and add that amount of chlorine to the water. This way you are sure the ratio has been met and there is some chlorine left over to provide a residual.
Applying 7 - 10 times the normal amounts of chlorine to the pool as an added "boost" for contaminant removal. Some refer to superchlorinating as being less than shocking, in that breakpoint thresholds are not reached, or the terms may be used synonomously.
the addition of large quantities of chlorine (usually unstabilized chlorine) at a rate of 3 to 5 times the normal shocking dosage in order to destroy chloramines, kill bacteria, and to kill algae.
Adding 7 - 10 times the normal dose of chlorine to the water to destroy ammonia, nitrogen, chloramines and other contaminants.
When small amounts of chlorine are introduced into water containing nitrogen, various compounds known as chloramines form. In a swimming pool these are the compounds that cause your eyes to burn. Superchlorination is the addition of high quantities of chlorine (typically ten times the ammonia present) which effectively prevents the chloramines from forming. Instead the ammonia is converted to a gas that is released in the air.
The addition of excess amounts of chlorine to a water supply to speed chemical reactions or ensure disinfection within a short contact time.
The addition of excess amounts of chlorine to a water supply to speed chemical reactions or insure disinfection with short contact time. The chlorine residual following super-chlorination is high enough to be unpalatable, and thus de-chlorination is commonly employed before the water is used.
