Study for Assessing Effluents Quality for Factories in Khartoum North- Sudan

Abstract

The current study was carried out in three factories namely; Bittar Oil and Soap, Tital factory and Ridda factory which they were present in Industrial area of Khartoum North, Sudan to evaluate the pollution in these factories. The samples were collected from the last manhole of discharge waste to the common sewer through aseptic tank. Parameters used according to the industrial waste water local order 1971 to determine the limits of oil and grease, temperature and pH. The liquid wastes sampled & analyzed for their chemical characteristic in accordance with Standard Methods (American Public Health Association, American Water Works Association & Water Pollution Control Federation, 1989). The physical characteristics were determined after temperature was measured immediately at sampling time; using a mercury thermometer in degrees centigrade and the pH value by electric pH-meter & conductivity by conductivity-meter, odor and color by (Human sense). The results obtained showed that the three factories in Khartoum North Industrial area have an adverse impact on the sewer system.In order to minimize or prevent or control the health hazards resulting from their effects, the study has recommended more practical, efficient and economical control methods and measures or technological treatment facilities and these are:1-Enforcement of criteria, standards, legislations and laws special for the protection of the environment or the work environment.2-Coupling of oil recovery tanks with septic tanks in the pretreatment. The effluent can be discharged into public sewers or used as irrigation.
