Changing Polluted Water Become Clean Water

When disaster strikes, scarcity of clean water would be an issue that needs attention. In this condition have many sources of water pollution. Then how to treat the polluted water?

Two-thirds of the weight of the human body is water. This enables man to survive without food for three weeks, but it is impossible to live without water for more than three days.
Water conditions are considered safe and healthy consumption is a clear, colorless, odorless, tasteless, free from disease and free mikroorgansime containing hazardous chemicals.

With the natural disasters certainly make a lot of clean polluted water sources, either because of biological hazards (such as viruses, bacteria or worms) or chemical hazards (such as detergents, solvents, cyanide, heavy metals, minerals and organic acids, nitrogen compounds, sulfides, ammonia and toxic organic compounds biocidal large varieties).

Biological hazards can cause health problems such as:
    1. diarrhea
    2. worm infections
    3. Dysentery (both amoeba and bacteria)
    4. cholera
    5. gastric problems
    6. typhoid
    7. jaundice

While the chemical hazards can cause health problems as follows:
    1. dermatitis
    2. intestinal disorders
    3. Liver disorders, bone and circulatory system, birth anomalies
    4. Anemia, bone marrow damage, leukemia
    5. Central nervous system damage
    6. problem carcinogenic

How to purify contaminated water?
Reporting from Webhealthcentre, purification of water which is mostly done there are three stages, namely, storage, filtration and chlorination. But it seems that three phases are not yet sufficient to completely purify contaminated water.

Here are some other ways to reduce the danger of contamination of water both biologically and chemically:

1. Filtering and boiling
Although they are clean, the water will be drunk to be filtered and boiled it to boil for at least 5-10 minutes. It can kill bacteria, spores, ova, cysts and sterilize water. This process also removes carbon dioxide and calcium carbonate precipitation.

2. chemical disinfection
This is useful for purifying water that is stored in a place such as in stagnant water, water tanks or wells.

3. bleaching powder
This process is a chlorinated lime. 2.3 grams of powdered bleach needed to disinfect a cubic meter (1,000 liters) of water. But the water is very polluted and turbid could not be purified by this method.
Bleaching powder is an unstable compound with strong odors. When this compound is exposed to air, light or moisture, then these compounds will rapidly lose chlorine levels, so that it becomes ineffective.

4. chlorine tablets
Market, chlorine tablets sold as tablets halazone. These compounds may be quite costly but effective way to purify water with a small scale.
Chlorine tablets 'smarter' has been introduced recently. Chlorine tablets is 15-20 times more powerful than halogen tablets. One pill 0.5 gms, sufficient to disinfect 20 liters of water.

5.FilterThere are several types of filters, including ceramic filter 'candles' and UV filters.
The main part of a ceramic filter 'candles' wax is made ​​of porcelain or infusorial ground. Its surface is coated with silver catalyst so that bacteria that enter into will be killed. This method eliminates bacteria that are commonly found in drinking water, but ineffective with viruses that can escape the filter.
UV filter tool generally consists of a prefilter, namely physical dirt filter. Carbon cartridge removes organic impurities from the water color, odor, and other chlorine-free. While the function of UV rays to eliminate bacteria and viruses.
