Harnessing the Potential of Zeolite‐Derived Bio‐Structures for the Treatment of Industrial Wastewater Effluents

ABSTRACT Industrial textile effluents pose a persistent environmental challenge, often resisting conventional treatment methods. This study investigates zeolite‐derived bio‐structure integrated with microbial isolates including Escherichia coli , Bacillus subtilis , Pseudomonas fluorescens , Aspergillus niger and Penicillium chrysogenum for textile wastewater remediation. These organisms were immobilized onto zeolite matrices to form a synergistic biofilm. The A. niger ‐based biostructure achieved notable reductions in chemical oxygen demand (COD) by 47%, total suspended solids (TSS) by 56% and total dissolved solids (TDS) by 68%. Bacterial biostructure significantly lowered biological oxygen demand with 85.60 ± 1.25, 80.26 ± 1.23 and 82.72 ± 0.54 mg/L for E. coli , B. subtilis and P. fluorescens , respectively. The COD level decreased to 625 ± 1.25, 605 ± 2.70 and 654 ± 1.60 mg/L while the TSS and TDS were reduced to 712 ± 1.78, 658 ± 1.87, 705 ± 9.34 mg/L and 2424 ± 3.52, 2354 ± 2.72, 2470 ± 1.24 mg/L, respectively. This integrated approach offers a sustainable and cost‐effective solution for improving key physico‐chemical parameters in industrial wastewater, enhancing pollutant removal and ecological safety.
