Better than Bleach: Use Calcium Hypochlorite to Disinfect Water
-
Knowing how to make your water safe to drink can not only keep you healthy – it could save your life. We often take for granted access to safe, uncontaminated, potable water. So much so that many people do not have the means or knowledge necessary to destroy disease causing organisms that may be lurking in their water supply. Many outdoorsmen, survivalists, and households preparing for emergency disasters rely upon common household bleach as a disinfecting agent to make water safe to drink.Calcium Hypochlorite |Calcium hypochlorite CAS 7778-54-3 | Water Treatment Chemicals | calcium hypochlorite uses |Calcium Hypochlorite manufacturer | Manufacturing Facilities For Calcium Hypochlorite | blogs on calcium hypochlorite | How Much Bleach To Use In Swimming Pools? |Benefits Of Bleach- Swimming Pool Water Treatment | Importance Of Chlorine – Hypochlorite
Bleach will destroy most (but NOT all!) disease causing organisms (boiling water to make it safe to drink is always the best method). However there is a readily available chemical that far surpasses common household bleach in terms of the amount of water it treats per unit of volume and weight AND in terms of shelf-life, which is perhaps it most important advantage of all.
In fact, not understanding the limitations of household bleach could jeopardize your health and perhaps even your life in a survival situation. What is not well known is Calcium Hypochlorite is far better for chemically disinfecting water.
Old Way: Using Bleach to Disinfect Water
I cringe to think how many people have expired bleach in their disaster emergency kits that will be used for treating polluted water.
Those of us who have emergency preparedness stocks of survival food and survival gear often keep a gallon or two of unscented household bleach on hand for making safe drinking water in large quantities.
Bleach is often the chemical of choice because it is commonly available and frequently mentioned when discussing the how-to’s of drinking water sanitation.
Typical fresh household chlorine bleach has about 5.35% chlorine content (be sure to read the label).To use household bleach for disinfecting water:
Add two drops of bleach per quart or liter of water.
Stir it well.
Let the mixture stand for a half hour before drinking.If the water is cloudy with suspended particles:
First filter the water as best you can.
Double the amount of bleach you add to the water.Why Using Bleach to Disinfect Contaminated Water is a Problem A little known problem with long term storage of bleach in your disaster emergency supply cache is that it degrades over time. Consulting a Chlorox bleach representative produced this statement:
“We recommend storing our bleach at room temperatures. It can be stored for about 6 months at temperatures between 50 and 70 degrees Fahrenheit. After this time, bleach will be begin to degrade at a rate of 20% each year until totally degraded to salt and water. Storing at temperatures much higher than 70 degrees Fahrenheit could cause the bleach to lose its effectiveness and degrade more rapidly.Use Calcium Hypochlorite to Disinfect Water A 1-pound pag of calcium hypochlorite in granular form will treat up to 10,000 gallons of drinking water. Calcium hypochlorite is one of the best chemical disinfectants for water, better than household bleach by far.
It destroys a variety of disease causing organisms including bacteria, yeast, fungus, spores, and viruses. Calcium Hypochlorite is widely available for use as swimming pool chlorine tablets or white powder that is much more stable than chlorine. This is often known as “pool shock”.How to Disinfect Water Using Calcium Hypochlorite
Using granular calcium hypochlorite to disinfect water is a three step process:
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 (eight liters) of water.To disinfect water add one part of this chlorine solution to 100 parts water to be treated. Let the mixture sit for at least one-half hour before drinking.
Be sure to obtain the dry granular calcium hypochlorite since once it is made into a liquid solution it will begin to degrade and eventually become useless as a disinfecting agent. This also means you should make your treated drinking water in small batches, for example enough for a few weeks at a time at most.
A Little Calcium Hypochlorite Makes Many Gallons of Potable Water Another plus for using calcium hypochlorite to disinfect water for emergency use is that a little goes a very long way. A 1-pound pag of calcium hypochlorite in granular form typically costs only a few US dollars and can be obtained in any swimming pool supply section of your hardware store or online. This amount will treat up to 10,000 gallons of drinking water, which is enough for a family of four for some six or seven years at a gallon per day per person!
Calcium hypochlorite will store for a long period of time and remain effective as a chemical drinking water treatment. So get rid of the household bleach and buy a can of Calcium hypochlorite for your disaster emergency water disinfection needs. It lasts far longer and treats far more water than the traditional chlorine bleach water disinfection treatment. So there you have it: when it comes to making water safe to drink you are better off having a small stockpile of calcium hypochlorite than jugs of bleach.
Blogs - calcium hypochlorite, you can use to sanitize your Swimming pool. Commercial products called bleaching powder, chlorine powder is uses in wastewater treatment & cleaning.
Calcium Hypochlorite (65-70% Purity) is water treatment chemical and a main product of ours. We manufacture it with advanced technology at our factory and it can be used for water treatment for swimming pool, disinfectant, irrigation water and industrial water treatment.
