the water is first screened then filtered to remove undesolvable objects then passed into the sedimentation tank which is again filtered after leaving the tank. Chlorine is then added to the fine filtered water to kill viruses and bacteria. now the water is clean hope i ave help u enough
Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.
These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution. Let's examine these steps in more detail.
Molar mass of sodium=23g 2 mole sodium gives 2 g H2 i.e 46g sodium gives 2g H2 so 65.4g will give=2.84g H2 now no. of molecules = 2.8/2*avogadros number
