Textile effluent is the major contributor of water pollution and increasing stringent regulations to meet sustainability standards have enabled many fashion brands exploring sustainable treatment methods. With environmental and economic challenges associated with conventional physical and chemical treatment methods, constructed wetlands have been identified as a sustainable approach to effective textile wastewater treatment.

This study explores the potential of inoculating beneficial bacteria in the constructed wetlands to enhance the degradability conditions of these systems. It was carried out in Pakistan, where a vertical flow constructed wetland reactor was set up.

A wetland plant, Typha domingensis, was vegetated in the reactor and inoculated with two endophytic bacterial strains Microbacterium and Bacillus which possessed textile effluent-degrading and plant growth-promoting activities.

Results showed that the inoculated endophytic bacteria significantly improved the total effluent degradation and mutagen reduction, while also promoting plant growth and increasing the number of effluent degrading bacteria in the plant roots. The resultant effluent met the wastewater discharge standards of Pakistan and could be discharged into the environment without any risks.
