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. The first process in water treatment is called screening, fixed screens are used to remove large particles from the raw mater. 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. 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. After screening the raw water enters the sedimentation tank where smaller sized particles which pass the screens are removed. Water then goes to the coagulation tank where the surface of the particles are modified by adding chemicals and ions of opposite charges to prevent some repulsive forces that are present. The final process is chlorination to kill disease causing organisms and some bacteria. Because of all this processes, water treatment therefore has many advantages that make it useful to people and every organism in a farm. Treated water is important to someone’s health because it prevents occurrence of many health complications that may occur because of drinking 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. 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 treatment leads to a cleaner and brighter laundry because due to softening of water during the process, hardness which may make laundry look dirty is removed.
