Abstract :
The contamination of paper industry effluents with diverse chemical and biological pollutants represents a significant environmental challenge. In this study, bagasse was investigated as a biosorbent for pollutant removal from pulp and paper industry wastewater. The adsorbent was characterized using Fourier-transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM) prior to application. The laboratory-scale study examined critical parameters affecting chemical oxygen demand (COD) removal, including pH, adsorbent concentration, and contact time. Additionally, pH played a crucial role. Multiple tests revealed that bagasse achieved optimal COD removal efficiency (78.6%) at an adsorbent concentration of 5 g/l, a contact time of 30 minutes, and a pH of 9.8. This performance was notably superior to that of other tested adsorbents, namely peat (~45%) and specialty fibers (~52%). The findings of this study can contribute to advancing wastewater treatment technologies and promoting the use of natural materials in environmental processes.
