A Guide to Water Treatment Water treatment is the removal of impurities such as suspended matter, bad colours,tastes and minerals such as iron and manganese from water in order to make it safe to humans, living organisms in the farm and also to help in various uses like industrial water supply and water recreation. Water that is used for consumption is supposed to undergo various processes in order to make it safe for drinking because raw water contains impurities that may cause health hazards. If raw water contains materials and suspended particles which are greater than 1mm then preliminary screening is necessary by use of screens of different apertures. 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. 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. Therefore water treatment has a lot of benefits to people and a farm at large. Treated water is important to someone’s health because it prevents occurrence of many health complications that may occur because of drinking 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. There are some microorganisms that are very dangerous to someone’s health and may cause intoxications, therefore treating water will prevent any of the organisms from surviving in water. 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. 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. 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.
