dc.description.abstract	The wide use of chemicals in textile production is common phenomenon. The aim of this study was to characterize the physicochemical properties of liquid wastes of BahirDar textile factory. A total of five samples, one was from a factory liquid effluent before treatment (S1), the second was effluent taken from the out let after it undergoes the electrolysis treatment (S2), the third one was from the out let of the treatment plant after it passed through biological treatment (S3),the fourth one was taken from the effluent after it was subjected to chemical coagulation and flocculation (S4) and the last was from finally treated effluent (S5) were taken and characterization of the effluents in terms of their degree of treatability was done. Evaluation of those samples for various parameters such as, as Total Dissolved solid (TDS),Total Suspended Solids(TSS),Chemical Oxygen Demand(COD), Biochemical Oxygen Demand (BOD), pH, turbidity, Electrical Conductivity (EC), Dissolved Oxygen(DO), Total hardness, Sulfate and Chloride content and analysis of heavy metals like Cadmium(Cd), Chromium(Cr), Iron(Fe), Lead Pb), Zinc(Zn).The observed mean values showed that the factory’s treatment plant was efficient to treat the parameters like: pH, TDS, EC, COD, Cl- , SO4 2- , T O, DO ,Cu and turbidity, their respective mean values were being in the range of 7.10±0.20 - 8.89±0.05, 220.00±2.1-620.00±0.76, 495.00±6.50 - 1120.00±2.00, 240.33±2.50 - 1152.00±2.00, 2.00±0.01 - 20.00±0.01, 39.23±1.03- 112.82 , 28.5±0.50-44.33±0.76, 0.41±0.15-7.01±0.03, 0.22±0.09-0.35±0.00 and 59.80±2.20 -410.00±5.00 respectively, but un efficient to treat the remaining studied parameters like: TSS, BOD5, Total hardness and heavy metals like Pb, Cr, Cd and Fe , their respective mean values being:219.00±1.00-1932.33±2.52, 60.33d±2.3-287.67±1.53, 700.00±6.00-1110.00±2.20, 1.07±0.64-1.48±0.00, 0.48±0.00-1.81±0.00, 0.07±0.02, 0.48±0.05-3.74±0.10 and respectively, since the values were above the permissible limits set by EPA for textile liquid waste to be discharged in to water bodies. The study confirmed its objective, the results showed the current degree of textile liquid waste toxicity, currently some parameters being dangerous to our living environment and will result undeniable problem for the coming generations, this calls for well-organized cooperative work for waste minimization and for taking an immediate action for a better effluent treatment.	en_US
