Abstract

This study aimed to measure and evaluate the quality of waste water treatment in the Medical Military Hospital in Omdurman, using some microbial ,physical and chemical indicators and tests for sample of waste water before and after treatment, Physio-chemical parameters Biological Oxygen Demand ,Chemical Oxygen Demand ,pH of water, Electric Conductivity, Total Dissolved Solid , Total Suspended Solid , Oils and Greases , the amount of Residual Chlorine , Phosphates ,and Ammonia, the use Microbiological Test are Total Account of Bacteria ,and Total Coliforms,the result showed that the values of these microbial and physiochemical parameters differ according to the sampling period in the year,the results were analyzed using the statistical variation program (ANOVA),where there is significant difference between the allowable limit and the after treatment results for the Biological Oxygen Demand ,the consumed Chemical Oxygen Demand and Phosphates and Ammonia to the Total Solids and Total Number of Bacteria and Coliform Bacteria and you find significant differences between the after treatment results and the allowabsle limit for to test Chlorine , Olis and Greases,Electrical Conductivity and Total Dissolved and Suspended substances,this study clearly demonstrate the need for adequate wastewater treatment methods before being discharged into natural water sources in order to reduce environmental risks.
