Water Treatment System

Processes involved in water treatment for drinking purposes to provide a safe source of water supply may solids separation using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation. For most people, the term “water treatment system” refers to the production of drinking water from the raw water, whereas “wastewater treatment” refers to the treatment of polluted water, where the pollution can come from human waste, industrial, agricultural wastes or other sources of pollution.Processes for drinking water treatment system


Processes for drinkingwater treatment System

  • Pre-chlorination for algae control and arresting any biological growth
  • Aeration along with pre-chlorination for removal of dissolved iron and manganese
  • Coagulation – for flocculation
  • Coagulant aids, also known as polyelectrolytes – to improve coagulation and for thicker floc formation
  • Sedimentation – for solids separation, that is, removal of suspended solids trapped in the floc
  • Filtration – removing particles from water
  • Desalination – Process of removing salt from the water
  • Disinfection – for killing bacteria.

Technology for the treatment of drinking water are well developed, and the general design is available which is used by many water utilities (public or private). In addition, a number of private companies provide solutions patented technology. Automation of water and waste water treatment common in developed countries. Capital costs, operating costs provided quality monitoring technology, local skills available usually dictate the level of automation adopted for water treatment system
