Your life may depend on these simple and inexpensive techniques. You can apply them when you are not sure of the source of the water or in cases of emergency.
The World Health Organisation reports that waterborne diseases account for an estimated 4.1% of the total daily global burden of disease, and causes about 1.8 million human deaths annually. It estimates that 88% of that burden is attributable to unsafe water supply, sanitation and hygiene.
As we all know, It is not enough for water to appear clean. Clean – looking water may contain harmful viruses or bacteria lurking in them. So to make it ideal for drinking, you need to 1. Clean as well as 2. Purify your water before drinking. Note that the regular filters only filter dirt which is not same as purifying water.
1. You Start by making your water Clean – when your supply is obviously dirty, cloudy or coloured.
In cleaning your water, start by washing your containers with soap. This is important because the container you are using for storage may be contaminated, which makes your water unsafe.
Next, make a Filter by putting a fine-mesh nylon stocking inside a clean white sock, and slowly pour the water into it. As you do so keep the sock-filter from coming into contact with the cleaned water, and make sure that the dirty water does not overflow from the filter. You should repeat this process until your water looks clean enough.
2. The next thing to do is to purify your cleaned water
The best purification method is by boiling. Let it be at a rolling boil of at least 1 minute. Then let it cool off before drinking
Another method is to use chlorine or bleach. It is important that you know about this because sometimes you may not have enough or any kerosene to carry out the process of boiling, which makes it undesirable.
After adding bleach, stir the water thoroughly in order to mix the bleach with the water and let it sit for 30 minutes. You should be able to detect the smell of chlorine after the waiting period.
Do not use scented bleach for purification. Bleaches which contain additional cleaners or other additives, should not be used to purify drinking water.
There are other simple methods of purification you can apply at home. This includes the use of Iodine, Hydrogen Peroxide or wine. However, boiling or a filter designed for a higher level of purification, is required to eliminate ‘Crypto’ which is a common microscopic parasite that causes diarrhea.
It would be nice to know about other simple methods one can apply to purify water at home. Please share your comments.
