What are Some Easy Ways to Purify Water?

Whether storing water around the home as part of an emergency kit, using water on a camping trip, or making the tap water in the home healthier and better tasting, there are a few simple and quick ways to purify water. Here are four basic methods to achieve water purification around the house or while enjoying the great outdoors.

For in-home use, the easiest way to purify water is to make use of a water filter. Water filters come in two basic models. One approach is to use a pitcher that is fitted with a water filter and holding tank. Tap water is placed into the holding tank and slowly works its way through a filter. The filter removes impurities from the water, and deposits the purified water into the bottom section of the pitcher.

A second option is to attach a devise containing a water filter to the tap itself. As the water flows out of the spigot, the filter removes contaminants and leaves behind crystal clear water that can be used for drinking or cooking. With both applications, manufacturers provide replacement filters that should be inserted into the pitcher or tap device on a regular basis.

When it comes to the task of storing water as part of a home emergency kit, there are two approaches that may be used to purify water. One involves the purchase of purification tablets. While different tablets are formulated at different strengths, they all involve dropping the tablet into a receptacle filled with water. Be sure to read the instructions to determine how much water can be cleansed with one tablet, and also how long the purification tablet will help to keep the water safe for drinking.

Along with water tablets, common household bleach can be used to purify water. Only pure and unscented bleach should be used for this application. The amount of bleach required to properly purify water depends on the amount of water in the receptacle. Sixteen drops of pure bleach, measured with a standard sized eyedropper, is usually considered enough to do the job. Once the bleach is administered, stir the water to distribute the bleach evening throughout the liquid. The water should have a slight chlorine scent. Remember to turn water storage containers once a month to prevent settling.

On camping trips, boiling water is a common method used to purify water. Place the water is a heatproof container, and bring the water to a rolling boil. An open fire or propane stove will work fine for this application. As the boiling activity takes place, a thin layer of residue will rise to the top. Skim off the top layer and allow the rest of the water to cool. The purified water can be poured into a container and used for drinking and cooking.

Generally speaking, you would want to have the water achieve a rolling boil and then allow the boiling to continue at least five minutes. Ten minutes is often recommended in many camping and wilderness survival guides.

Keep in mind that the degree of contamination in the water, plus the position above sea level can also impact the amount of time needed to adequately purify the water. At sea level five to ten minutes will do the trick. At higher levels, add some additional time.

How long do you boil water to purify it ? 5 minutes ? 10 minutes ?

Does a microwave oven purify water, if so, how long do you micro-wave the water for ? Thanks for any tips :-)
