Textile wastewater contains enormous dyes and chemicals with detrimental environmental effects on both micro and macro fauna and flora due to its chemical compositions. Therefore, wastewater discharges from three Nigeria textile companies (S1, S2 and S3) were analyzed for some physicochemical characteristics such as temperature, pH, suspended solids (SS), total solids (TS), biochemical oxygen demand (BOD), dissolved oxygen (DO), chemical oxygen demand (COD) and heavy metals concentration using standard laboratory methods. Results obtained revealed the range of values for the above named characteristics as follows: Temperature (20 – 32 oC), pH (6.3–9.0), TSS (206 - 420 mg/l), TDS (1537.20 - 3472.50 mg/l), DO (3.5 – 5.2 mg/l), BOD (65 – 85 mg/l) , and COD (120 – 195 mg/l). Similarly, heavy metals were detected in various concentrations: Copper (Cu) (4.40-5.60 mg/l), Lead (Pb) (0.42-0.97 mg/l), Cadmium (Cd) (1.80-2.40 mg/l), Chromium (Cr) (0.33 – 0.46 mg/l), Zinc (Zn) (1.20 – 2.20 mg/l) and Iron (Fe) (22.39-24.03 mg/l). These values were higher than the FEPA acceptable limit and indicate that the textile wastewaters were highly polluted. Therefore, urgent attention is needed to protect the quality of the receiving surface water bodies.
