Why Water Treatment is so Important to Your Health

The water is a simple chemical compound, but with complex properties because of its bias. The chemical formula of water is H2O. That is, each water molecule consists of one oxygen atom between two hydrogen atoms. Water is indispensable for human health and well-being; there can be no life on Earth without water. In fact, the human body is composed of 70% water. However, that same water can do harm to your body if not purified. Unfiltered water contains chlorine, fluoride, dioxins, parasites, etc. those could be hazardous to your health.

Why water treatment is so important?

The water is found almost everywhere on Earth. Water resources like rivers, lakes, which provide water contain a lot of pollution, garbage unfit for consumption. To be clean, the water should undergo a number of treatments necessary to make it drinkable. Water purifiers designed to eliminate or reduce certain pollutants (nitrates, pesticides, heavy metals, organic materials…), as well as improve the quality taste of water (eliminating chlorine).

If you are like one of most people out there, you may say “I have been drinking unfiltered water for years, I never am sick”. Some diseases take time to present visible signs, but it does not mean they are inactive in your organism. WHO list a list of WATERBORNE DISEASES that kill people all over the world: diarrheal disease, Hepatitis A, Cholera, Botulism, Typhoid, Dysentery, Cryptosporidiosis, Polio, etc. those diseases can be caused by protozoa, viruses, bacteria, and intestinal parasites

Different methods of purification

Below, are three main techniques of water treatment used in the United State:

Distillation - distillation is the process of heating the water until it boils, capturing and cooling the resultant hot vapors, and collecting the condensed vapors. The impurities will "accompany" the steam and end up in distillate. This method is not new; mankind has been applying distillation for thousands of years. Not all modern distillation equipments are the same. If you are interested in treating your water by distillation, you should choose good or advanced water purifiers for better result. The problem with the method of distillation is kind of slow comparably to reverse osmosis and UV water treatment method.

Reverse Osmosis - The tap water passes through a semi-permeable membrane that ranges from 90 to 99% of components originally present. This practice originally designed for industrial uses is becoming very popular today in domestic water purification. In practice, a portion of the water allows the rejection of impurities selected initially by the membrane, polyamide TFC. Very powerful, it is nevertheless sensitive to chlorine and must be protected with active carbon filters. Its life is about 5 to 8 years under normal conditions of use. This principle is also quite slow and requires a substantial pressure.

UV water purification - UV water purification technology is probably the most cost-effective and most efficient on the market today. It allows homeowners and business owners to remove a range of biological contaminants in their water supply. The UV water treatment offers many advantages over other forms of water treatment for microbiological contaminants. Most importantly, it leaves no chemical in water, it produces no by-product, and it does not change the taste, pH, or other properties of water. Consequently, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system.

The UV treatment is an excellent choice for eliminating biological contamination of most waters. If your home or business requires an additional filtration or if you have a source of private untreated water (rainwater, lake water, wells etc.). The unique objective of UV water treatment system is to kill harmful biological contaminants.
In any method (reverse osmosis, UV water treatment, distillation), it is imperative to change the filters regularly. Poorly maintained, activated carbon filters may prove ineffective. Worse, they can suddenly reject the impurities previously removed from the water.

MCLA students get close look at North Adams Water Treatment Facility
Thursday March 11, 2010 North Adams Transcript NORTH ADAMS -- Surrounded by the sound of rushing water, nine Massachusetts College of Liberal Arts students peered into the gaping basin below them, where thousands of gallons of water flowed through the filters of a clarifier at the city’s Water Treatment Facility on Wednesday.
