A Guide to Water Treatment
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 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. The first process in water treatment is called screening, fixed screens are used to remove large particles from the raw mater. 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. Fine screens are usually rotary drum screens whose surface is woven stainless steel with small screen aperture sizes, collected debris are washed at this place.
Settling or sedimentation is the next process where finer particles are removed because they may eventually block the filters. Water then undergoes coagulation and flocculation process that will help in agglomeration of smaller particles that permit settling in a reasonable time. Finally water treatment ends by disinfection to kill bacteria, other pathogens and bacteria either by adding of chlorine and other chemicals. Therefore water treatment has a lot of benefits to people and a farm at large. Water that is treated is very important for a person’s health because many cases of diseases are associated with drinking of untreated water. Treated water is good for appliances in a farm because water that is softened keeps many appliances efficient which will also help in saving money. Clean water is of good importance to someone’s health because it is free from disease causing organisms that may cause deaths. 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. Dissolved gases and and unpleasant tastes are usually removed when water undergoes the process of treatment this makes it better and efficient to be used by people for drinking purposes. 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.
