Effective incorporation of microalgae for textile wastewater (TWW) treatment presents a promising avenue for addressing environmental challenges related to water pollution. Microalgae can effectively metabolize pollutants and offer a sustainable solution for remediating TWW. Recent advancements in cultivation techniques, such as photobioreactors (PBRs) and genetic engineering, have bolstered scalability and efficiency, facilitating the integration of microalgae into existing treatment infrastructure. PBRs provide controlled environments for cultivating microalgae, optimizing their growth and pollutant removal capabilities for TWW treatment. Genetic engineering techniques enable the enhancement of microalgae strains, tailoring them to efficiently metabolize specific contaminants found in TWW, thus improving bioremediation efficiency. The synergy between PBRs and genetic engineering offers a promising approach for sustainable TWW treatment, leveraging advanced technology to mitigate environmental impact and promote resource recovery. Algae-based nanoformulations for TWW remediation also possess potential. Again, the utilization of microalgal biomass for biofuel production, biofertilizers, and high-value products not only enhances the economic viability of wastewater treatment systems but also promotes circular economy principles. Despite these advancements, challenges related to scalability, cost-effectiveness, and regulatory frameworks persist, necessitating further research and innovation. Future endeavors should prioritize optimizing cultivation techniques, enhancing pollutant removal efficiencies, and evaluating the overall environmental and economic sustainability of microalgae-based wastewater treatment systems. Again, bioflocculants enhance microalgae-based TWW treatment by improving pollutant removal, promoting sustainability, and reducing chemical use in remediation. Ultimately, the integration of microalgae stands as a promising strategy for achieving sustainable TWW treatment, offering opportunities for environmental remediation, resource recovery, and the advancement of circular economy practices in the textile industry.
