Water prufication using "Pool Shock"
« on: December 13, 2009, 10:29:35 PM »
I have heard about a product called "Pool Shock" for water decontamination if you don't have a filter unit.
Apparently it'either Calcium Hypochloride or Sodium Hypocloride. Basically Chlorine in concentrated powder.
It stores about forever if kept from moisture.
I cannot find good info on how much to use with water to make the mix.
Does anyone have any information on this?
Thanks

Yes it can be used...BUT...it is also very corrosive and will deteriorate any container (except glass) that it is stored in.  It is known to rapidly decompose when exposed to air and release toxic chlorine gas.  Handle with care.  Better yet don't handle at all and if you want to chemically disinfect water use 5% Sodium hypochlorite which is household bleach.  Make sure it is fragrance free and just like your food supply rotate your stocks and use the oldest first.  Use 8 drops (1/8 tsp) per gallon of CLEAR water. If after treating there is no slight bleach oder, reapply.

Use the pool shock to make chlorine, then apply the chlorine to the water in question. I found this article, there are others online. Also addressed elsewhere on this site.

How to Make Chlorine Bleach from Pool Shock
http://www.thefoodguys.com/howtoclorox.htm

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 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 completely agree with this, especially the last part. Pool chemical companies often add other stuff to keep swimming pools "sparkly" that are not good for people.

I used to have a pool growing up and knew the value of "shock" I currently keep a small container in my preps along with a mixing ratio printed out and taped to the container.

So when mixed up how does it compare to a bottle of bleach?  Will it work for doing laundry?
