Why Water Treatment is Important
Water treatment is the process of removing contaminants and undesirable components in water making it more acceptable to be used for different purposes, for example, drinking, irrigation, and river flow maintenance. Treatment of drinking water involves a series processes that are aimed at the removal of particles that may lead to contamination and cause short and long term risks. First of all water is supposed to undergo the process of screening to remove the suspended particles which may include debris and vegetation, screens of different sizes are usually used. Course screens are often fixed bar screens that have a screen surface which consists of various vertical metal bars of a given thickness that are spaced at specific intervals depending on how it is supposed to be applied. Intermediate screens are fitted with water cleaning jets which wash away any debris remaining after getting out of the course screens.
The next step is sedimentation where the smaller particulate matter is removed. The next process is flocculation where smaller particles are collected into round masses and the surface of the chemical environment are usually added with chemicals, after this process the small particles behave as single larger particles which settle and are removed as sludge. Filtration is the next process that helps removing some particles by passing through a series of sand filters, the high rate sand filter is usually easy to clean and reduces the load of particulate materials on the slow sand filter. Water treatment is therefore important to human beings and even farm animals. Water that is treated is very important for a person’s health because many cases of diseases are associated with drinking of untreated water. Some equipment requires treated water in order to work effectively for example softened water can be used in heat exchange equipment to prevent scale formation ,it also helps in removal of soluble salts which can influence texture of some vegetables. Water that is treated offers protection from harmful organisms such as microorganisms that may lead to illnesses like severe vomiting and diarrhea because it ensures that all the organisms are killed making water safe for consumption. Since there is presence of metals in water, treatment is very important to remove them because some may cause health hazards, for example, lead and copper are dangerous to health hence chemicals, and filtration systems are used to remove them in order to prevent risks. The bad odors and taste of water is removed when water is treated that’s why some food beverages taste better when prepared using treated water. Water that is soft due to treatment allows detergents to rinse completely because fabrics are softer without hard water minerals trapped in them, it also allows a person to save on the amount of soap he or she uses.
