Dissipation of Chlorine in Drinking Water of Bhubaneswar Water Supply System, Odisha India

摘要

Water samples were collected from 55 sampling stations of three water treatment plants at Bhubaneswar city, Odisha for analysis of residual chlorine. On the basis of distance from the source, the total study area was sub-divided into short (< 6.9 ton), medium (6.9-10.4 km) and long (>10.4 km) distance. Average chlorine content was highest in short distance (0.934 mg/L) followed by medium (0.756 mg/L) and long distance (0.684 mg/L). One way ANOVA test on chlorine content of water supplied from treatment plants to different locations on the basis of distance showed a significant difference (F = 90.522; p < 0.05). The regression value for short distance was; r~2 = 0.816, 0.841 and 0.865 against linear, quadratic and cubic models. Similarly for medium distance; r~2 was 0.969, 0.969 and 0.969 and for long distance; r was 0.867, 0.868 and 0.868 against linear, quadratic and cubic models respectively.
