Water Purification Systems

There are many ways to purify water, I have:

1. Sawyer mini's
2. Big Berky
3. Alexapure
4. Impregnated silver dome filters for my homemade system
5. Charcoal for another one of my homemade system

Here are instructions on how to purify water by the sun - NOTE: this does not remove heavy metals.

(Snip) ... When and How to Treat Water for Storage

In an emergency, if you do not have water that you know is safe, it’s possible to purify water for drinking. Start with the cleanest water you can find and treat with one of the following methods:

• Boiling and chlorinating: Water can be purified by boiling. Boiling times may vary from state to state, depending on altitude. In Colorado, the water is safe to use once after it has been boiled for three to five minutes and has cooled. If you plan to store boiled water, pour it into clean, sanitized containers and let it cool to room temperature. Then add 5-7 drops, or 1/8 teaspoon, of chlorine bleach* per gallon of water (1/2 teaspoon per 5 gallons). Stir or shake the solution to mix it. Cap the containers and store them in a cool, dry place.
   
  
• Filtering and chlorinating: You can filter water if you have a commercial or backpack filter that filters to 1 micron. These are available in sporting good stores and are recommended for use when back-packing. They are not recommended to clean large volumes of water. Filtering eliminates parasites such as giardia and cryptosporidium, but it may not eliminate all bacteria and viruses. Therefore, it’s recommended that 5-7 drops (1/8 teaspoon) of chlorine bleach* be added per gallon of filtered water (1/2 teaspoon for 5 gallons). Stir or shake the solution to mix it. Wait 30 minutes before using the water, or cap the containers and store them in a cool, dry place.
  
  *Use liquid household bleach that contains 5.25 percent hypochlorite. Do not use bleaches with fresheners or scents as they may not be safe to consume. The above treatment methods use a two-step approach so less bleach is needed, yet giardia and cryptosporidium are destroyed through boiling or eliminated by filtering. Chlorine may not be effective against these parasites. Since adding too much chlorine to water can be harmful, it’s important to be as accurate as possible when measuring.
  
   
  
• Distillation Distillation involves boiling water and then collecting the vapor that condenses back to water. The condensed vapor will not include salt and other impurities. To distill, fill a pot halfway with water. Tie a cup to the handle on the pot’s lid so that the cup will hang right-side-up when the lid is upside-down (make sure the cup is not dangling into the water) and boil the water for 20 minutes. The water that drips from the lid into the cup is distilled.
  

Most water filtration devices are designed for use on microbiologically safe water. Don’t assume they are safe to use on contaminated water. Check with the manufacturer to be sure.

Use the following guidelines to determine if filtration equipment is adequate to use with microbiologically contaminated water:



Equipment that is safe to use on contaminated water is often slow, costly, inconvenient and/or high maintenance. It makes the most sense to use the filtration equipment that best meets your normal daily needs and shift to water storage or alternative methods of water treatment in times of emergencies.
