Effect of Aluozozab Sewage Disposal on Water Quality in White Nile River, Sudan

This study was conducted during July to October 2017, in the White Nile at Khartoum state, to determine the effect of industrial sanitation and effluents of Aluzozab discharge channel, the discharge come from Soba Sanitation plant, Elyarmok industerial complex and other industerial waste water to the White Nile water quality, Water samples were taken every 10 days from (4) locations, location (A) southern Jebel Awulia dam, location (B) northern Jebel Awulia dam, location (C) the discharge channel, location (D) Northern of the discharge channel..Samples of water were taken to analyze some physical, chemical properties and lead (pb) concentration at the National center lab in Khartoum city.. The study concluded that there is no significant differences in temperature measurement in the (4) locations, but there was significant difference in electric conductivity, biological oxygen demand, chemical oxygen demand, dissolved oxygen and lead concentration. E.C values were (0.1345 ms/ cm) in site A, (0.1280ms/cm) in site B, (1.0185ms/cm) in site C, and (0.36775ms/cm) in site D. The BOD values were (5.630mg/l) in site A, (5.020mg/l) in site B, ( 58.770mg/l) in site C and (5.830mg/l)in site D The COD values were (11.840mg/l) in site A, (10.990mg/l) in site B, (136.900mg/l) in site C and (12.500mg/l)in site D.The lead concentration values in site A(0.0197mg/l). in site B (0.0329mg/l) , in site C(0.0585mg/l) and site D(0.0382mg/l). The dissolved oxygen concentration was high in site A (6.580mg/l), in site B (5.640mg/l), lower (0.780mg/L) in the discharge channel and (3.980mg/l) in site D that may be due to existence of pollutants.
