How Water Treatment Works
Clean water is a right for everyone, whether they live in a big city or a rural village. Water treatment plants make this a reality for many people living in denser areas, by cleaning and purifying water that comes out of the tap for use in the home. Almost all water that passes through a city’s supply is treated so that it is safe to drink. This is how that is accomplished.
Water to be purified is first collected in a centralized location, generally a reservoir found near the water purification plant. Collected water may be water which is pumped out of the ground, or water that has been reclaimed after use. However, these two types of water are sometimes not treated together, since they may have different treatment needs.
First, all particles must be removed from the water, including those that are too small to see. As long as these particles are in the water, the additives used in treatment may not disperse properly. There are several different methods for removing sediments, including filtering the water and holding it still in a tank to allow the sediment to settle to the bottom.
Next, the water is disinfectant to remove potentially disease causing microorganisms. Ground water especially may also be treated with a compound such as activated charcoal to remove taste and odor from the water. After this, the water is filtered again to remove the compounds.
Adding Beneficial Compounds
All tap water in the United States has fluoride added to promote healthy teeth. Additional compounds may be added to the water as needed depending on the area. For example, stabilizing compounds or softeners may be added to adjust the pH o the water.
