Physico-chemical analysis of Sewage water treatment plant at Jagjeetpur Haridwar, Uttarakhand

Abstract

Water is quite essential natural element for all kinds of life. The quality of water is vital concern for mankind since it is Water is quite essential natural element for all kinds of life. The quality of water is vital concern for mankind since it is directly linked with human welfare. The wat er samples were collected from sewage treatment plant ( reatment plant (from both 18 MLD and 27 MLD) situated in Jagjeetpur, Haridwar situated in Jagjeetpur, Haridwar. The study was carried out for a period of four months and total 15 sampling were done during this period. Results revealed that in done during this period. Results revealed that in inlet pH varied from 7.13 to 8.76 and in outlet 6.01 to 8.2, total solids in inlet varied from 751 mg/l to 897 mg/l and in outlet from 509 mg/l to 749 mg/l. The total hardness in inlet otal solids in inlet varied from 751 mg/l to 897 mg/l and in outlet from 509 mg/l to 749 mg/l. The was found between 212mg/l was found between 212mg/l to 249 mg/l and in outlet from 178 mg/l to 210 mg/l. Chloride in inlet varied from 96.5 mg/l to 210 mg/l. Chloride in inlet varied from 96.5 mg/l to 112.9 mg/l and in outlet 45.4 mg/l to 57.2 mg/l , alkalinity values in inlet were reported between 178 mg/l to 211 mg/l and between 178 mg/l to 211 mg/l and in outlet from 154 mg/l to 205 mg/l. Dissolve d oxygen in inlet was found between 0.70 mg/l to 1.96 mg/l and in outlet from to 1.96 mg/l and in outlet from 4.01 mg/l to 6.22 mg/l. Biochemical oxygen demand in inlet ranges from 90 mg/l to 129 mg/l and in outlet from 3.6 oxygen demand in inlet ranges from 90 mg/l to 129 mg/l and in outlet from 3.6 mg/l to 8.5 mg/l , Chemical oxygen demand in inlet ranges from 231 mg/l to 252 mg/l and in outle t from 16 mg/l to 30 mg/l. This Chemical oxygen demand in inlet ranges from 231 mg/l to 252 mg/l and in outle study showed that both the treatment plant s are working in good condition.
