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. Water treatment for drinking water involves removal of any contaminants to produce pure water that may be used for human consumption without any risks or health effects. 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. The course screens are usually the first screens the screening process; they are usually spaced at a space of 25 to 100 intervals, water then flows to intermediate and fine screens. Raw water then goes to the intermediate screens that are often traveling bands, the screen surface is usually vertical through which the water stream flows.
The next step is sedimentation where the smaller particulate matter is removed. Water then undergoes coagulation and flocculation process that will help in agglomeration of smaller particles that permit settling in a reasonable time. Water is taken to a filtration chamber to remove some of the particles from water by passing it through a sand bed that is designed to allow reusing, the chamber also consists of several filters for example the slow rate, pressure and high rate sand filter. Because of all this processes, water treatment therefore has many advantages that make it useful to people and every organism in a farm. 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. Clean water is of good importance to someone’s health because it is free from disease causing organisms that may cause deaths. In addition, treated water also helps in removal of toxic metals because is a source of minerals like magnesium and also copper that are dangerous to a person’s health and may cause some diseases in future. Water treatment helps in the removal of unpleasant tastes and odors that are present, this makes water good compared to when it was still raw. When water is treated, it is usually soft hence economical because less soap will be used compared to when the water is still hard and untreated.
