| Abstract | ||||
| The stream sanitation and pollution control is dependent on natural self- purification, the ability of the stream to assimilate wastes and restore its own quality. The stream solvency in transit along its course reflected by the balance of outgo and income dictated by four primary self-purification factors: 1) stream runoff, 2) time of passage, 3) temperature and 4) reaeration. The dissolved oxygen (DO) profile resulting from specific organic waste loading has been considered as an indicator of the stream condition. In this work, an analytical model has been used to predict the DO profile along to drains in Egypt. The calculated DO shows a good agreement with those values obtained from the field measurements. Introduction: One of the most critical problems today, which requires a quick solution, is the failure of water to meet the required demands. This arose the need to protect the available surface water sources from pollution.One major source of surface water pollution is the discharging of raw or treated -sewage into the surface water stream. The impact of pollution on the receiving water body is manifold and dependent upon the type and concentration of the pollutants (Nemerow and Dasgupta, 1991). The different pollutants, e.g. pathogens, cusnended solids organic matter. algae. nitrate, salts, etc. have different | ||||
