Abstract
Access to clean water is a global challenge, and membrane-based filtration is a promising solution. This review explores bio-based additives integrated into membrane materials to improve water purification. Enhanced membrane properties, facilitated by natural additives, can increase efficiency, sustainability, and environmental compatibility. Recent research underscores the potential of bio-based additives to refine membrane performance while reducing ecological impact. However, challenges remain in ensuring long-term stability and economic feasibility for large-scale applications. The review highlights the importance of continued scientific inquiry and innovative techniques to advance the field. It emphasizes the need for interdisciplinary collaboration among experts in materials science, chemical engineering, and environmental sciences. By understanding and improving the integration of bio-based additives, the membrane industry can progress towards more sustainable, high-performing, and economically viable solutions. Ultimately, the successful deployment of these technologies could contribute to providing cleaner, safer water supplies worldwide and addressing one of humanity’s most pressing concerns. • Bio-based additives enhance membrane hydrophilicity, permeability, and antifouling properties. • Incorporating biopolymers improves membrane mechanical strength and separation efficiency. • Bio-based membrane modifications offer eco-friendly and sustainable water treatment solutions. • Phase inversion and interfacial polymerization enable effective integration of bio-based additives. • Challenges include cost, stability, and large-scale application of bio-based membrane additives.
