How Do Activated Carbon Water Filtration Systems Work And What Is Their Capacity To Purify Water?

4706 words - 19 pages

AbstractIn this experiment, the research was to see the effects of carbon filters in removing the chlorine from tap water. The research question was to determine how do activated carbon water filtration systems work? What is their capacity to purify water? The purpose of this was to test if water filters really do occupy the capacity stated as well as the removal of substances such as chlorine.Since chlorine can damage the human body, filters are used to reduce the amount of chlorine within the water. In this experiment, samples of water from the tap and filter were tested. As the experiment proceeded, silver nitrate was used to calculate the amount of chloride ions within the substance. As precipitation occurred when silver nitrate was placed in the water, the Ksp value was used and further calculations determined the amount of chlorine in the water. Further tests could have included looking through microscopic machines that would show when the precipitation occurred and as a result make the lab more precise. The experiment was to show how much carbon filters removed chloride ions from the water. Also, it was tested if the capacity that water filters can take was either correct or not.As a result of this experiment, it showed that the filters really do last the capacity given by the manufacturer. However, the amount of chlorine reduced by the product was inefficient as it stated to remove 99% of chlorine in which in this experiment, only around 50% of chlorine was extracted from the water. It is seen that even though around 2ppm of chlorine was reduced in the experiment, it is “safer” to drink filtered water as it reduces the chances of getting debilitated by chlorine.[295 words]IntroductionWater is a required nutrient for all living organisms. Recommended human consumption is up to 8 glasses of water a day. Untreated water can cause many problems or damage the human body because of the organisms within it. Water is treated with chlorine to prevent the growth of these bacteria or micro-organisms. Chlorine can play a negative role in the body because it or the compounds it forms may be carcinogenic which becomes a more significant factor when large amounts of chlorinated water are consumed. Chlorine gas is dissolved in water though a process involving the compressions of chlorine gas. The compressed gas, now in its liquid form is reacted with water to kill harmful bacteria. Hypochlorous acid and hydrochloric acid are produced when the chlorine reacts with water according to the following equation Cl2+H2O==>HClO+H++Cl- . Since chlorine gas is very toxic, some possibilities of its danger could be caused by accidental release from storage tanks and therefore chlorinated hydrocarbons may form. This is caused by chlorine reacting with carbon or other hydrocarbons. Examples of these substances are dichloromethane, trichloroethylene, and chloroform. Hydrocarbons known as trihalomethanes can produce problems in the liver, central nervous...
