While checking out a few sites on preps, I found this: http://readynutrition.com/resources/shtf-planning-3-ways-to-purify-water_24052014/%5B/embed ]
Here’s the part that’ll get Preppers into trouble and quickly reduced the effectiveness of your Neighborhood Protection Team and/or family to zero:
To avoid water-related illnesses, it is imperative to learn how to filter your water using materials available to you. Here are three ways of purifying water for drinking. These are also great projects to do with children to teach them this valuable skill.
1. Homemade Water Filter
When you begin to filter water from lakes, rivers and groundwater, there are 4 steps to keep in mind:
1. Coagulation: removes dirt, metals and other particles suspended in water. Chemicals like Alum are added to the water that form sticky particles called “floc” which attract the dirt particles.
2. Sedimentation: the combined weight of the sediment and chemicals stuck together become heavy and sink to the bottom.
3. Filtration: smaller particles are removed as water passes through a series of filters (sand, gravel, charcoal)
4. Disinfection: to kill bacteria or microorganisms found in the water, a small amount of chlorine is added.
Materials You Will Need:
- 1-liter soda bottles cut in half
- Napkins, cheesecloth or paper towels
- Activated Filter Carbon (available at pet stores)
- Large water container for dirty water (pitchers or gallon jugs)
- Dirty water (made by adding dirt, twigs, leaves, etc., to water)
- Large waste container (plastic container, thick garbage bag, etc.)
- *Potable Aqua Chlorine Dioxide, water purification drops or tablets
- 2 clean pitchers for filtered water
- Cut 1-liter soda bottle in half and put top of soda bottle upside-down (similar to a funnel) inside the bottom half. The top half will build the filter, the bottom half will hold the filtered water.
- Add napkin, cheesecloth or paper towel at the neck of the inverted bottle.
- Add filtration materials in this sequence:Add unfiltered water and allow water to seep through the filter.
- 1 inch of charcoal
- 2 inches sand
- 1 inch gravel
- 2 inches sand
- 1 inch gravel
- Add unfiltered water and allow water to seep through the filter.
- For added measure, it is recommended to chemically treat filtered water to kill off any pathogens that were not filtered.
All this filter does without the chemicals is remove large debris and sediment. It cannot remove any pathogen by ‘filtering’ with charcoal or sand.
However, Sawyer brand filters can, and do. You can find them here. Here’s why, and this is from Sawyer:
“…Each filter is certified for ABSOLUTE microns; that means there is no pore size larger than 0.1 or 0.02 micron in size. This makes it impossible for harmful bacteria, protozoa, or cysts like E. coli, Giradia, Vibrio cholerae and Salmonella typhi (which cause Cholera and Typhoid) to pass through the Sawyer PointONE™ biological filter. At 7 log (99.99999%) the filter attains the highest
level of filtration available today. If viruses are an issue, we offer the Point ZeroTWO Purifier (0.02 micron absolute pores), the first and thus far only portable purification device to physically remove viruses, which it does at a >5.5 log (99.9997%) rate, exceeding EPA and NSF recommendations. All Sawyer filters have been tested by independent and qualified research laboratories according to U.S. EPA standards for water filters, and meet or exceed EPA standards. Sawyer’s revolutionary technology has also been tested and
verified by the United Nations, and is currently being used in more than 70 countries around the world. “
Here’s their rating chart:
Now, I’m sure the article’s author was well meaning, and thought they were showing some good improvisation, but the information on filtration was wrong and dangerous to preppers. Dysentery is not anything to laugh about.
Spend the money on this system for your family: The Sawyer Point Zero Two Bucket Purifier Kit. All you do is provide the bucket. This small, lightweight filter kit can provide up to 170 gallons of clean water per day. Assembly Kit Includes: Hole Cutter, a Sawyer Point ZeroTWO™ 0.02 Micron Absolute Inline Water Purifier, adapter, hose, Filter Cleaner, Filter Hanger, and detailed instruction book.
$125 for this one. What’s your family’s health worth?
GLSC also has portable systems which DTG actually uses in the field and carries. By the way, we all have one of the above systems at home because we know how important clean water is to life. Additionally, we carry stabilized oxygen with us in the field to add to our purified water, “just in case.”
So, it’s up to you. Grab some dirt, buy some charcoal, get some empty pop bottles and ‘filter’ your water and experience the joys of Dysentery, or do it right and get a Sawyer system.
Think I’ll go have some purified water…..
