Hey all,
Another strange question. We all know sodium chlorate is the expensive guy. You usually get way too much calcium hypochlorite . I know that you can make bleach from this cheap pool shock. Here's where it gets interesting .
If you boil household bleach on a camp stove outside til crystals form....pour out the liquid and keep heating til dry you get sodium chlorate!
..........................RECIPE FOR BLEACH........................
Make Chlorine Bleach from Pool Shock
Straight off the EPA site...
We bought a 5 lb. bottle of "Shock" from Walmart for $10.97, you can find it in the pool chemical section. Make sure that it is the "Calcium Hypochlorite" not the "Sodium". MAKE SURE IT HAS NO OTHER ADDITIVES!!!!!!!!!!!
This 5 lb. bottle makes 640 gallons of "stock chlorine" (eliminates purchasing 640 gallons of bleach). Each of these 640 gallons of stock chlorine disinfects 200 gallons of water. For a total of 128,000 gallons of clean drinking water for the cost of one bottle of "Shock". And think of the space it'll save.
Directions are at
www.epa.gov/ogwdw000/faq/emerg.html or as follows:
GRANULAR CALCIUM HYPOCHLORITE.
Add and dissolve one heaping teaspoon of high-test granular calcium hypochlorite (approximately 1/4 ounce) for each two gallons of water. The mixture will produce a "stock chlorine" solution of approximately 500 mg/L, since the calcium hypochlorite has an available cchlorine equal to 70
percent of its weight. (THESE STOCK CHLORINE GALLONS ARE LIKE BLEACH GALLONS)
To disinfect water, add the clorine solution in the ratio of one part of chlorine solution to each 100 parts of water to be treated. This is roughly equal to adding 1 pint (16 0z.) of stock chlorine to each 12.5 gallons of water to be disinfected. To remove any objectionable chlorine odor, aerate the water by allowing the water to stand exposed to the air for a few hours
or by pouring it from one clean container to another several times.
As always if the water is colored or cloudy add more of the solution (EPA says for regular Chlorine Bleach to double the amount of chlorine used).
I feel Jim would be interested in this bit of info if you guys run out of sodium hypochlorite but still have pool shock!
What da you think?
