I once visited a friend in another neighborhood and thought that their water is usually purified just like ours. I therefore went ahead and drank water from the cistern without the knowledge that water from the cistern in their neighborhood is not meant for drinking but for farming purposes. After several minutes, I began feeling ill. I vomited and later on started to diarrhea. I was taken to the hospital and treated and eventually my health resumed to normal after three days. It is the worst experience I have ever had in my life. I would not wish any other person to have such an experience ever. This can only be possible if there are drinking water filtration systems in water sources in all neighborhoods. Water filtration systems are of significant importance. Water is very essential for human survival. On average, the human body is more than 70 percent water. Vital systems and organs including liver, brain and blood are over 80 percent water. This illustrates the fact that human beings, to a large degree, are what they drink. The importance of water in human body is underlined by the role that water plays especially as regards every chemical reaction (Gertsen and Linus 16). Water aids in absorption of food, digestion, regulation of body temperature, carrying nutrients to cells, blood circulation, and excretion of wastes among others. In addition, water cushions body joints and protect organs and tissues from damage and shock. Conversely, when human body dehydrates or lack water, it can cause many ailments. Extreme dehydration can aggravate or cause many problems such as allergies, migraine headaches, asthma, and hypertension. It is not enough to have water. the water must be pure and uncontaminated for human consumption. Contaminated water is the cause of numerous degenerative diseases, as well as neurological illnesses such as Chronic Fatigue Syndrome, depression, Attention Deficit Disorder, and anxiety among others (Coca-Prados and Gemma 44). Considering the important role of water in the functioning of all body systems and organs, its purity is the most essential and basic key to proper human health and longevity. There are various methods of ensuring that drinking water is pure and safe for human consumption including filtration, use of chemical disinfectant, and boiling of water (Omelchenko, Alexander and Swindall 9). Filtration using water filtration systems has proved to be one of the most common methods of purifying water. These systems facilitate filtration of water thereby removing particles from water as the water filters or passes through the systems. There are three methods used in water filtration systems. The first one is sediment filtration that removes clay, impurities, and sand from the water. The second one is carbon filtration that is used in reducing poor taste, chemical quantities, chlorine odor, as well as other pollutants. The third method is reverse osmosis, which entails removing several impurities from water such as turbidity, salts, chlorine, and dissolved solids, as well as bacteria and many dissolved organics. Reverse osmosis is considered the most effective of the three filtration methods (Gertsen and Linus 52).
