Abstract

Samples of domestic sewage obtained from a sewage treatment plant located in Warri, Nigeria were analysed for some pollution characteristics such as permanganate value (PV), suspended solids (SS), biochemical oxygen demand (BOD) and chemical oxygen demand.Values obtained from the analysis were used to assess any relationship between the pollution characteristics using correlation and regression analysis.  Mean values of the pollution characteristics had the following range of values: PV (162.20-286.00)mg/L, SS (200.00-380.00)mg/L, BOD (163.70-220.74)mg/L, and COD (286.22-355.56)mg/L. The relationships assessed (i.e. PV/SS, PV/BOD and PV/COD), regression equations and correlation coefficients obtained   were: PV=0.6962SS+21.973; r = 0.938, PV=1.0853BOD – 16.751; r = 0.593 and PV=1.174COD – 177.7 ; r = 0.730 respectively. The analysis revealed that strong and significant linear relationship exists between suspended solids and permanganate value in the domestic sewage. Keywords: Regression analysis, Correlation, SS, PV, BOD, COD, Domestic Sewage, Pollution.
