Disinfection with Calcium Hypochlorite
Omega Man Journal ^ | 4/13/12

Posted on 09/13/2012 12:27:48 PM PDT by Kartographer

This journal entry is a continuation of my series of entries on disinfection of drinking water. Please read the following linked articles first, Introduction to Disinfection and Disinfection with Sodium Hypochlorite. I have covered a lot of background information already, which you will need to fully understand this journal entry. Go ahead, I’ll wait.

Calcium Hypochlorite, Ca(OCl)₂ is a solid chemical used as a disinfectant and bleaching agent. It is used to store chlorine for long periods of time without having to resort to chlorine gas, which is extremely dangerous if not handled properly. If stored is a room temperature environment away from moisture, temperature extremes and direct sunlight, calcium hypochlorite can last up to a year without serious degradation. Beyond a year the chemical will become weaker with time.

Calcium hypochlorite is very similar to sodium hypochlorite. The biggest difference is in the appearance. Calcium hypo is a white powder and sodium hypo is a yellow liquid. Sodium hypochlorite is a liquid and can be added directly to water for disinfection. Calcium hypochlorite on the other hand, needs to be mixed into solution first. Then added to the water for disinfection.

I think Costco had some big buckets of this stuff when I was in there last.

I’ve got a boatload of both dichlor and trichlor (pool shock). Does your pdf manual have instructions on using those?

They store forever, and a box the size of a dictionary would purify a small city’s worth of water.

Here’s a link for using dichlor:

Thanks Kart.

By coincidence, I just added some to the stash last week. I thought it was supposed to be ‘good’ (only slightly diminished effectiveness) for up to about three years, if kept dry and somewhat sealed from the atmosphere though.

Thank you for the ping, Kart, as always.

Has anyone actually used this stuff? I’d be interested in hearing first=hand commentary.

I use Shcl every day. We use about 2 1/2 gallons to disinfect 50,000 gallons of water. Get a cheap test kit from Hach, so you know when it’s “right.”

I figured the powdered or tablet stuff would last a lot longer. Store it right!

The family has owned construction companies that deal mainly with municipal water and sewerage.

We use the granulated stuff for sanitizing new potable water tanks (think 100s of thousands gallon size).

Same here. I thought it only degraded after being mixed with water.

The article instructs that the disinfectant solution be made by adding 28 OZ of calcium hypochlorite to a gallon of water. Is that accurate?

I have. you take one heaping half teaspoon to 1 gal jug of water. let it sit for i think about 3 to 4 hours. This will purify 100 gallons of water. i buy 76% which is hard to find. i bag does 10,000 gallons. i have 7 bags for prep. i dont think sams sells calcium only sodium. good luck

Not all pool shock has the correct ingredients. Anything with an algeacide in it also shouldn’t be used.

To make a stock of chlorine solution (do not drink this!) dissolve 1 heaping teaspoon (about one-quarter of an ounce) of high-test (78%) granular calcium hypochlorite for each two gallons of water.

Yes. That's why I am asking about the data in the article you posted. Did you read the article before you offered it up as reliable information?

What about the people who read your post and now believe they need to add over a pound and a half of calcium hypochlorite to a gallon of water to make a disinfecting solution?

The article clear states:

To recap, to mix a 15% solution hypochorite solution, add 21 grams to 100 mL of water.

It then goes on to say:

Here is a list of other common measurements.

No where does it say add a half pound to a gallon of water.

"No where does it say add a half pound to a gallon of water"

No it doesn't. Nor did I claim it did. It says, as I pointed out, to add over 1.5 lbs. What does this (from your article) say?

Can I get on your ping survival list?

(I cannot use private posting apparently, sorry for the public one. Anyone know when I can use the private method?)

Can you think? All of those numbers equal a ratio of over 1.5 pounds of calcium hypochlorite to one gallon of water.

Is that the correct recipe??granules

You just can't get it or don't wish to get it or you can't read. The author gives the formula of 21 grams to 100 mL of water and then goes on to list some other common measurements. The common measurements are for reference and are not part of the formula. How come 50 or 60 people got that, but you can't seem the grasp it?

Are you confusing dry volume with weight?

A cup of sugar (8 oz volume) weighs about 5 oz.

To make a solution that is similar, but stronger, to what you can get in a bleach bottle, those numbers are about correct.

To sanitize water.... You'll need to use some of that solution to sanitize the water. 50 ppm is about right, and can be tested for.

Did you miss that step?

Thanks, no, I didn't miss that step. The recipe given for the disinfecting solution is way off.

It's not the formula for a disinfecting solution.

It's the formula for making the kind of stuff you buy in the store (3 times stronger, though). that you mix with water to make a disinfecting solution.

If you have a correct recipe, I'd love to see it. Perhaps we could step through it together.

Any chance we could get the recipe in ONE unit of measure... SAE or MKS? Furlongs per fortnight...

Teaspoons and 'about' and liters is a little confusing for a simple cook like me.
