A 12% solution is widely used in waterworks for the chlorination of water and a 15% solution is more commonly used for disinfection of waste water in treatment plants. High-test hypochlorite (HTH) is sold for chlorination of swimming pools and contains approximately 30% calcium hypochlorite. The crystalline salt is also sold for the same use; this salt usually contains less than 50% of calcium hypochlorite. However, the level of active chlorine may be much higher.
Application
-
Also used as a disinfectant and germicide , especially in the sterilization of water.
-
It is also used for making wool unshrinkable and in the manufactire of chloroform.
-
For the purpose of disinfection and bleaching , a weak soln. ( 1.2 % ) is used. For purifying water 0.02 to 0 .2 % volumetric is sufficientPotable Water Treatment

HANDLING AND STORAGE PRECAUTIONS:
Do not store adjacent to chemicals that may react if spillage occurs. Comply with Oman regulations, when shipped. If closed containers become heated, vent to release decomposition products (mainly oxygen under normal decomposition). Do not mix or contaminate with ammonia, hydrocarbons, acids, alcohol or ethers.
DO NOT REUSE CONTAINERS: Product residues may remain in containers. All labeled precautions MUST be observed. Dispose of container in a manner meeting government regulations.
PRODUCT DISPOSAL: Product should be completely removed from containers. Material that cannot be used or chemically reprocessed should be disposed of, in a manner meeting government regulations.

General formulation to calculate how much bleach is needed to add to a tank or a pipeline to disinfect it to a given chlorine residual using a given disinfectant. Usually someone wants to know how to meet an AWWA Standard (like C651-92, Disinfection of Water Mains). The equation below should be used to estimate the amount of sodium / Calcium hypochlorite (Chlorine Water is 6.00% sodium hypochlorite) needed to disinfect a given quantity of water to a desired chlorine concentration.
|
req'd residual in ppm |
For example , say you had installed a new 5,000 gallon tank and wanted to make sure that you had at least a 100 ppm solution of chlorine in it.
How much 6.00% Hypochlorite would you need to add ?
- (5,000 gal x 100 ppm) / (1,000,000 x .06) = 8.33 gallons
How much 12% Hypochlorite solution would you need ?
- (5,000 gal x 100 ppm) / (1,000,000 x .12) = 4.17 gallons
If you use calcium hypochlorite (the white, powder version of chlorine, like HTH pool cleaner), the equation becomes:
|
req'd residual in PPM |
- This is simply the previous equation multiplied by the conversion factor of 8.33 pounds per gallon of water.
Let's assume that we still need to disinfect 5,000 gallons at 100 ppm.
How many pounds of 65% calcium hypochlorite (HTH pool cleaner) are needed?
- (8.33 lbs/ gal. x 5,000 gal x 100 ppm) / (1,000,000 x .65) = 6.4 pounds
