Water Treatment Presentation

By: Saya Parker

Water treatment is the processes involved in treating water for drinking purpose that may be solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation. In this type of treatment there is a process. I am going to tell you.  In this process there are 6 commonly steps. The first one is Disinfection. In this process chlorine is added to the water or disinfecting. The next process is coagulation and flocculation. In this process alum is added in proportion to the river turbidity to form floc particles created from the suspended materials in the water. The next process is sedimentation. In this process the water travels through Sedimentation Basins where the heavier materials settles. Next process if filtration. In this process following sedimentation, the water travels through an extensive filtration process that removes sediment and other suspended materials. The next process is corrosion control. This is a process where the pH is adjusted with caustic soda (NaOH) to reduce corrosion in plumbing systems. The last process is distribution. In this process the water is not crystal-clear and safe to drink.
