| Abstract | ||||
| Sewage is water-carried wastes, in either solution or suspension that is intended to flow away from a community .It is more than 99.9% pure water and is characterized by its volume or rate of flow, its physical condition, its chemical constituents, and the bacteriological organisms that it contains. Domestic sewage causes a problemto environment so that the treatment and disposal of wastewater is not only desirable but also necessary (1). In this study, we are concerned with the sewage treatment using different techniques. Two major techniques were applied for wastewater treatment, namely biological and chemical treatments. In biological treatment we constructed a pilot and bench scale for applying the two aerobic and anaerobic techniques to reduce some of the studied parameters as BOD, COD, nitrogen and phosphorous at the optimum condition from used time and sludges and compared these results with effluents from plant. In chemical treatment the jar test technique was used where coagulants matter as alum, ferric chloride and polymer are added by a suitable dose of each coagulants. | ||||
