Wastewater reclamation and reuse in petroleum refinery at Algeili Area north of Khartoum

الملخص EN

This study was conducted at Khartoum Petroleum Refinery at Algeili, North of Khartoum.

The study discusses waste-water treatment methods in the refinery as well as final disposal methods applied on reclaimed water.

Waste-water reuse in irrigation was presented in the study as well as its effect on plants and crops.

The objective of this study is to assess the methods of waste-water treatment adopted in the environment at evaporation ponds near the refinery.

After tests and experiment done on the wastewater treatment units and evaporation ponds, the treatment by plant gave good results of water reclamation.99.6 percent of oil was removed during the processes, 99.76 percent of volatile phenol was eliminated, and COD value decreased by 77.4 percent, however, it increased once more at the evaporation ponds due to algae presence and high temperature.

PH value had also increased at the ponds for the same reason.

Therefore the study recommends adopting waste-water reuse methods for irrigation.

Such method preserves the environment and might minimize the effect of groundwater recharge from heavy-flow point source into negligible-flow non-point source and hence causes less contamination.
