Water: Filtering-General Information

Filtering and chlorinating:
http://www.nationalterroralert.com/safewater/

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:

* 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.

There are a number of devices on the market that filter out microorganisms. A water filter pumps water through a microscopic filter that is rated for a certain-size organism. ---CONTINUED---

WHAT WE DO : Bio-Sand Water Filter
https://www.son-international.org/water-filter-design-and-info

Bio-Sand Water Filter Description

Bio-sand filtration is a simple, cheap and effective means of removing disease-causing micro-organisms from contaminated water. It is a modification of traditional slow Filtration Technology that has been around for over 150 years. While the traditional slow-sand filter technology requires a continuous flow of water, this unique design was developed specifically for intermittent use in the households of developing countries where a continuous supply of water is usually difficult to maintain. It can be constructed out of low cost materials that are available world wide. This filter has no moving parts and is very low maintenance. Bio-sand filters have been shown to almost entirely remove harmful microbes found in water. This filter design has been introduced in more than 30 countries, by a variety of organizations and people.

Filtering through Fabric
* Link Unavailable. This site is no longer active and available to view on line. But the info was good and we wanted to keep sharing it!

:arrow: tigger2:
You can use a lot of stuff to clean up the water before you run through your filter. You could run it through a towel, cheese cloth or a pair of jeans. The cloth would act like a filter and get a lot of the big stuff out.

:arrow: Muzhik:
If you're going to use a cloth pre-filter, some things to keep in mind:
  • 1. The cloth should be 100% cotton with a medium-to-tight weave. Old tee shirts work really well for this.
    2. You should fold the fabric so that the water will go through 4 layers.
    3. You should use the cloth ONLY ONCE. After that the cloth needs to be washed and then dried in the sun before being used again.
This comes from some research in India, where public health officials were trying to find out why some families got sick drinking the river water and others didn't. It turns out the women who collected the water for the families that didn't get sick were running the water through folded parts of their cotton saris. The researchers found out that filtering your water through 4 layers of cotton cloth would remove up to 99% of biological contaminants. This means you can use this technique in an emergency. Just remember: the cloth needs to be dried in the sun to ensure any remaining germs, etc. get killed by the UV.

Water Purification: Improvised Charcoal Filter

(As featured in the May/June 2010 issue of Practically Seeking)

"Water water every where and not a drop to drink."

(SNIP) ... We are using a 2-liter plastic bottle for the "see through" value, but many other options are available to you, such as a sheet of tree bark rolled into a cone, a clay pot with a small hole in the bottom, a length of bamboo or cane, a glass bottle with the bottom removed (see our YouTube video)… Besides, these days, sadly, there is almost always plenty of usable refuse out there on the landscape :(

100-Year-Old Trick for Filtering Rainwater
https://survivallife.com/filter-rainwater/?utm_source=newsletter&utm_medium=email&utm_campaign=slnl042917

During our boiling, broiling, blistering summer of 2012 here in the Missouri Ozarks, water was a topic of conversation wherever we went. Creeks and ponds dried up (some never recovered) and the water table dropped, forcing a few neighbors to have their well pumps lowered or to even have deeper wells drilled.

Many folks shared memories of rain barrels, cisterns, hand pumps and drawing water with a well bucket as a child, usually on grandpa and grandma’s farm. Some said they’d never want to rely again on those old-time methods of getting water. But, at least they knew how it was done. --- CONTINUED at LINK, above ---

(SNIP) ... Those who feel that the cost of commercial water purifiers is heavy on the pockets, can opt for homemade water filters for safe and better tasting water.

They have several advantages over the commercial water filters. They are simple to make and easy to maintain. They can be made by using simple household items. However, you can also use prefabricated parts sold by the distributors. There are different types of water filters you can choose from. The best part is that they work just as the commercial ones, and guarantee safe and tasty water. ---CONTINUED---

Commercial Portable Water Filters
https://grandpappy.org/hwater.htm


This is a snip from a larger article on water, on his site. Scroll down the page to find:

Removes Protozoa, Bacteria, Most Viruses, Many Harmful Chemicals and Radioactive Particles.
To remove ALL Viruses, you must Boil the Water or Add Chlorine or Iodine.

The best overall method for improving the quality of water, but also the most expensive, is to use a commercial water filter, but not one that permanently connects to your home water system because it requires water pressure to function properly.

The one potential disadvantage of commercial water filters (not purifiers) is that they cannot remove 100% of ALL virus pathogens. Fortunately, waterborne virus pathogens are NOT a common problem in most areas. Therefore, unless there has been an outbreak of viral diseases in your area, then waterborne viruses will probably not be a problem with your water supply. However, if there has been a recent outbreak of viral diseases, then add the appropriate quantity of chlorine to the water, wait one-hour, and then put that treated water through one of the following filters. ---CONTINUED---
