Researchers used activated carbon made from sugarcane bagasse to remove pollutants from textile waste water. They tested different doses of the carbon, pH levels, and reaction times to find the best combination for removing BOD and COD efficiently. By optimizing these factors, they achieved maximum removal efficiencies of 0.0225 and 0.023 mg/L min−1 for BOD and COD, respectively. The rate constants for BOD and COD removal were found to be 0.028 and 0.0274 mg/L min−1, showing the effectiveness of the activated carbon in cleaning up the water.
