World Health Organization (WHO), 2015. Technical Briefing on Boil Water

Boiling

This is probably the most common and effective method you can use to prepare water for drinking. Boiling will kill most types of microorganisms and is relatively easy to do. Boil the water for at least 1 minute (5 minutes is better) and allow it to cool in a covered/protected location. (Drinking water that’s too hot can dehydrate you more).

Chemical Purification

If boiling your water isn’t option, chemical purification may provide the disinfection that you need. There are a variety of off the shelf chemicals that you can use to make water much safer to drink:

Solar Water Disinfection (SODIS)

The SODIS method is one of the easiest methods you can use to purify water. It is so easy in fact that there are many organizations that are attempting to teach this method to people who are in danger of succumbing to water borne illnesses.

Solar Distillation

A fourth option that you have to create clean, disease-free water is to make use of the sun's energy by building a solar still. This method requires lots of time and sunshine to get any appreciable amount of water. Another downside to this method is that the water will be devoid of any minerals or flavor.

Clarifying Water First

If the only water available to you is cloudy or laden with sediments, you should make an attempt to clarify it prior to disinfection. This can be accomplished by either straining the water through several layers of fabrics, such as clothing, or allowing the solids to settle out.

Bio-Sand Filtration

Surprisingly, one of the easiest ways to purify water is to use the sand and silt that makes up the Earth's surface all around us. It's a known fact that water that is pumped out of the ground is often free of contaminants because it has been naturally strained through the pores of sands and silts.

1. Boiling

The most basic method of all the ones listed here. If you have got a clean or fireproof vessel with you, then just pour in the water that is to be purified. First of all, you need to remove the large water impurities from it before you set it on the boil.

2. Solar Water Disinfection

Next interesting method for purifying the water is the Solar disinfection technique. There are many organizations putting in the efforts by teaching this method to the people living in an extremely bad condition.

3. Distillation

It’s the method in which condensed form of the water, that is the purest form of the water is collected.

4. Bio-Sand Filter

The water that comes from the ground side is considered pure, isn’t it? This is because, the water after passing through rocks, sand, silt, and other natural elements gets purified. You can make a bio-sand thing at your home too, and use it for filtering water.

5. Chemical Purification Methods

If none of the above methods worked for you, then turn towards the chemicals!

1. Boiling

If you don’t have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing organisms, including viruses, bacteria, and parasites.

2. Disinfectants

If you don’t have safe bottled water and if boiling is not possible, you often can make small quantities of filtered and settled water safer to drink by using a chemical disinfectant such as unscented household chlorine bleach.

3. Filters

Many portable water filters can remove disease-causing parasites such as Cryptosporidium and Giardia from drinking water.#N#If you are choosing a portable water filter:
