Assessment of the Effectiveness of Blue Nile and White Nile Water Treatment Plants in Khartoum State

Abstract

Treatment of water is considered as a critical challenge especially in developing countries since this treatment is an essential facility to conserve the public health and environment by eliminating of waterborne diseases and pathogens and make it acceptable to consumers. The objective of this research is to assess the efficiency of Blue Nile (Bahri and Mogran) and White Nile (Alshajra and Jabal Awlia) water treatment plants which consist to conventional water treatment units such as flocculation, sedimentation, filtration, and disinfection. Four water treatment plants were investigated in different areas and coordinates. Samples were carefully gathered from the study area (Khartoum state site area) according of approved sampling procedures. Several characteristics (Turbidity, Total Alkalinity, pH and residual chlorine) of both the raw and treated water were studied according to Standard Methods and Procedures to evaluate the performance and quality of treated water from Water Treatment Plants. The results show that the treated water from the plants meet specifications in terms of total alkalinity and pH, and often fail to satisfy specifications in terms of residual chlorine and turbidity. The study recommends to enhance the efficiency of treatment in terms of residual chlorine and turbidity specially during flooding season.
