    TREATMENT AND RECYCLING OF WASTE WATER AT KHARTOUM NORTH POWER STATION
    (Neelain University, 2008) Mayssa Mustafa Eltahir
    This study attempts to investigate the chemical and physical characteristics of Khartoum north Power station waste water and to suggest methods for treating this water before being discharged to river Nile. To achieve this goal numerous numbers of samples have been collected and examined to detect oil content, turbidity, suspended solids, total dissolved solids, pH, BOD, COD and conductivity. Average values of these results were calculated and compared with (WHO- 2003) guide lines. ~ The outcome of this phase study confirmed that waste water at Khartoum north Power station (KNPS) is heavily polluted with oil and other pollutants. For this reason a second phase of experiments is carried out mainly to remove or reduce oil content and other pollutants to levels which may comply with International regulations and local authority acts. The treatment phase of experiment comprising different processing units arranged in a logical sequence starting with units for oil removal through a coagulation process, sand filtering ending with ion exchange or reverse osmosis to remove dissolved solids. Results obtained fiom second phase of experiments after waste water being treated are encouraging and a total reduction in contamination of not less than 80% has been achieved. m
