Assessing the Performance of a Sewage Treatment Plant in Habbak, Srinagar: A Physicochemical Analysis

A study was carried out to assess the physicochemical profile of one of the sewage treatment plants in the Habak region of Srinagar city. The water samples from the inlet and outlet of the plant were analyzed for various limnological parameters like temperature, dissolved oxygen, free carbon dioxide, alkalinity, calcium and magnesium hardness, orthophosphate etc. The average water temperature recorded at the outlet and inlet ranged between 16.56 to 18.03oC, free carbon dioxide between 50.06 to 78.03 mg/l, alkalinity between 328 to 389 mg/l, calcium hardness between 83.41 to 85.12 mg/l, magnesium hardness between 614.58 to 783.53 mg/l, orthophosphate between 503.56 to 650μg/l respectively. The dissolved oxygen content at the inlet was found to be zero during all times in the study while the average value at the outlet was found to be 5.2 mg/l. All the parameters were found to be non-significant except for water temperature, dissolved oxygen, and total hardness.
