The widespread application of dyes in the textile sector results in the production of highly pigmented and contaminated wastewater, which presents considerable environmental and health risks. This research examines the efficiency of dye removal using eco-friendly bio-adsorbents derived from sugarcane bagasse and rice husk, both of which are plentiful agricultural by-products. The synthesized bio-adsorbents are characterized through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray diffraction (XRD) to evaluate their surface properties, structure, and crystallinity and amorphousness. Both agricultural wastes were subjected to drying, grinding, and chemical activation to enhance adsorption properties. The resulting composite bio-adsorbent was used on textile wastewater samples under controlled experimental conditions. Various adsorption tests were performed to analyze the removal effectiveness under different conditions, including contact time, pH, and dosage of the adsorbent. Furthermore, the effect of treatment on essential physicochemical parameters of the textile wastewater, such as pH, BOD, COD, total dissolved solids (TDS), electrical conductivity, salinity was examined. Kinetics adsorption study also shows here for analyzing the behavior and interaction between adsorbent and adsorbate. The results show a notable efficiency in color removal, supporting the viability of these affordable bio-adsorbents for sustainable and efficient wastewater treatment. For reactive dye waste water, bioadsorbent removed 80.13% color. For basic dye, it removed 87.80% color imparting particles. And for ETP inlet and outlet sample, the percentages were 73.56% and 44.12% respectively. The outcomes underscore a promising alternative to traditional treatment approaches by leveraging agricultural waste materials for environmental remediation.
