| dc.description.abstract | Due to the rapid population growth and industrialization, the status of environment is degrading from time to time. As the extent of Industrialization for development are extending to far flying areas in the world as well as in Ethiopia, the problem of wastewater management is causing a great concern to the environment. The wastewater generation from municipal and manufacturing industry increases along with population growth. The objective of this study is to evaluate the textile wastewater treatment plant unit efficiency hydraulic performance using design guideline and evaluating operational protocols based on Ethiopian Environmental Protection Agency and international wastewater effluent quality standard. Five sampling points were identified from Bahir Dar textile and the study was carried out on the basis of field analysis and characterization studies. The major pollution indicating parameters like biological oxygen demand, total dissolved solid, total suspended solid, ammonia, pH, dissolved oxygen, nitrate, nitrite and heavy metals were analyzed in Bahir Dar institute of technology Laboratory center. The hydraulic residence times of primary clarifier, aeration tank and secondary clarifier is 26.4, 38.25 and 28.26 hours, respectively, which were all more than the standard value. The total suspended solids and chemical oxygen demand effluent concentration were 60.9 and 138.46 mg/L respectively with removal percentage 22.24 and 80.54 % respectively which were again the above the required limit. The treatment plant pollutant removal efficiency is weak and corrective measurements on the operating problems and configuration of the plant are recommended to maximize the performance of the treatment plant. | en_US |
