Abstract
The discharge of zinc (Zn)-laden industrial effluents represents a persistent environmental concern due to the metal’s bioaccumulative nature and ecological toxicity. Conventional remediation technologies, including physicochemical separation and advanced oxidation, often involve high operational costs and generate secondary waste streams. Consequently, biological approaches, particularly bacterial sequestration using metal-resistant prokaryotes, have emerged as promising alternatives for sustainable wastewater management.
This study investigates the theoretical and functional potential of Zn sequestration through resistant bacterial systems, with specific emphasis on industrial discharge treatment. The research integrates concepts from microbial resistance, physicochemical dispersion modeling, and industrial process engineering to develop a comprehensive understanding of Zn removal mechanisms. The methodology is structured around microbial isolation, resistance profiling, biosorption kinetics, and system optimization under varying environmental conditions.
The analysis demonstrates that resistant prokaryotes exhibit significant Zn sequestration capacity through mechanisms such as extracellular adsorption, intracellular accumulation, and metabolic transformation. These findings align with previously reported microbial Zn remediation efficiency, indicating strong adaptability of bacterial systems in metal-contaminated environments (Pratap et al., 2022). Additionally, the study highlights the influence of wastewater heterogeneity and dispersion characteristics on treatment efficiency, drawing parallels with fluid transport and dispersion models used in environmental engineering (Chen et al., 2005).
The results indicate that optimized bacterial systems can achieve high Zn removal efficiency while simultaneously reducing organic pollutant loads. However, limitations related to process scalability, environmental variability, and microbial stability remain critical challenges for industrial implementation.
The study concludes that bacterial sequestration offers a viable, environmentally sustainable alternative for Zn removal from industrial discharges. The integration of microbial systems with advanced engineering frameworks can significantly enhance treatment efficiency and operational feasibility. This research contributes to the development of next-generation biotechnological solutions for industrial wastewater remediation.
