Analysis of pH Value of Water for Treatment Plant of Kekri and Surajpura (Rajasthan) India

Roop Singh Sinsinwar, Munna Verma


The basicity and acidity of a liquid are measured in terms of pH value and neutral pH value of water is 7.0. Hydrochloric acid (HCl) is added to reduce the pH value of water and carbon dioxide is added to increase the pH value of water. Temperature is one of the most important parameters that affect the equilibrium and pH value of water. The value of pH should be 6.5 to 8.5 in permissible drinking water if its value is lower than 6.5 in the water, then sodium carbonate and above than 8.5 then citric acid can be found. The pH value of blood in healthy people is more or less than 7.42. In the current research work three water treatment plants with a size of 600 MLD, 142 MLD and 132 MLD was used for treatment of raw water of a dam located in Tonk district named as Bisalpur. Poly aluminium chloride (PAC) was used in these water treatment plants as a coagulant to accumulate suspended particles such as sand, clay and biological organic load. The results obtained nearby the neutralized pH value 7.0 in increasing trend between 7.35 to 7.45.
