Here is Tuesday’s DIY for you… Need to make sure drinking water and water you take a bath in is clean? Not sure how you are going to purify those 50 gallon barrels of rain water??? Check out this DIY. Probably worth the purchase and worth the storage space…
Bleach will not last forever when you buy it in the grocery store. I replace a gallon a year generally just based on the solution weakening over time. It is inexpensive enough to replace, but what if you want to store massive amounts of bleach for purifying water for long periods of time?
I read a recent post on post SHTF infection, which made me consider cleanliness. Like many others I store gallons of bleach, but how long will a few gallons last, and how much room do I want to allocate for bleach storage? Well I found a way to store 640 gallons of bleach in about 1 cubic foot of space.
How to 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 http://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 chlorine 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).
