| dc.description | Water pollution arises as a consequence of the persistent release of industrial wastewater and effluents into aquatic ecosystems, including rivers and lakes. Annually, a significant quantity of hazardous substances such as toxic sludge, heavy metals, solvents, suspended solids, and other biological wastes are released into neighboring ecosystems by industrial establishments worldwide (Choudhary et al. 2020; Briffa et al. 2020). The majority of the pollutants included in these effluents consist of dissolved and emulsified natural compounds, suspended materials, such as clays and silica, sulfur, asbestos, lead, mercury, nitrates, phosphates, toluene, dyes, alkalis, acids, benzene, pesticides, chlorobenzene, polychlorinated biphenyls, volatile organic compounds, carbon tetrachloride, and hazardous solvents, (Tong et al. 2022; Nagendranatha Reddy et al. 2022; Briffa et al. 2020; Bhadauria et al. 2017; Kolya et al. 2017). | |
| dc.description.abstract | The treatment of industrial wastewater, containing various contaminants like chemicals, dyes, and heavy metals, has emerged as a significant environmental issue. Traditional treatment procedures, although successful, frequently include synthetic chemicals that are non-biodegradable and present hazards to both ecosystems and human health. Bio-flocculants, especially those originating from extracellular polymeric substances (EPS) generated by microorganisms, provide an environmentally benign and sustainable option. These bioflocculants utilize microbial enzymes and polymeric substances to efficiently agglomerate and eliminate contaminants, adhering to the principles of green chemistry. Recent studies have concentrated on enhancing bioflocculant manufacturing technologies and their utilization in industrial wastewater treatment. Research is directed on improving biodegradability, cost-efficiency, and pollutant removal efficacy. This paper analyzes the function of microbial-based bioflocculants in industrial wastewater treatment, emphasizing their ecological advantages, biodegradability, and economic efficiency. It also examines progress in bioflocculant synthesis, concentrating on the production and application of EPS. Contemporary research trends focus on enhancing bioflocculant manufacturing technologies and broadening their industrial uses. Future initiatives focus on improving the efficiency and scalability of bioflocculants to facilitate new and sustainable wastewater management solutions. Keywords: Biodegradability; Contaminants; Floculation; Pollutant removal; Sustainability | |
