Title: Assessment Of Industrial Wastewater Treatment System In Khartoum North Thermal Power Station
Author: Hamad, Rofida Hamad Khlifa
Abstract: Industries are major sources of pollution in all environments. This study aimed at assessing the current wastewater management regime in Khartoum North power station with a view to identify potential weaknesses and areas of improvement via analyzing the power plant final effluents discharged to the Blue Nile. Samples were collected from the power plant’s three phases final effluents during winter, summer and rainy season for the determination of pH, temperature, residual chlorine, turbidity, conductivity, total hardness, phosphate, SS, TDS, BOD, COD and oil and grease using standard procedures. Laboratory analysis results for the tested parameters were compared with the local standards for effluent discharge as well as the World Bank limits. The variations in the tested parameters for the effluents of the three phases of the power plant were found within the permissible limits for industrial effluents discharges except the BOD and the oil and grease values for phase 1 and 2 effluents across the various study’s seasons. The BOD values for phase 1 and 2 final effluents reached 107 mg/l in summer ; and the oil and grease values were 64 mg/l, 73.2 mg/l and 216.7 during winter summer and rainy season respectively. Generally; the laboratory analysis showed that the third phase of the power plant has a sound effluents treatment system while the first and second phases results showed the presence of some weaknesses in the effluents handling and treatment system; hence the current Khartoum North power plant phase 1 and 2 oil separation systems needs to be strengthened; and the values of oil and grease in the final effluents should be closely monitored in order to prevent the Blue Nile River pollution.
