- Abstract
The unwanted occurrence of antibiotics in the environment is an emerging concern of non-target toxicity and antimicrobial resistance. Floating treatment wetland (FTW) is a low-cost and ecofriendly wastewater remediation strategy; however, the effect of immobilized bacteria on its efficacy during the remediation of ciprofloxacin (CIP)-contaminated water has not been documented. In this study, Phragmites australis was planted to develop FTW, and it was augmented with a bacterial consortium (Acinetobacter lwoffii ACRH76, Bacillus pumulis C2A1, and Acinetobacter sp. HN3), with and without immobilization for the remediation of CIP-contaminated (100 mg L−1) water. The augmentation of bacteria (immobilized or in suspension) in the FTWs significantly increased the elimination of CIP from the water. Maximum removal of CIP (97%), COD (92%), BOD (93%), and TOC (90%) from the water was observed in the FTWs having immobilized bacteria. This research revealed that the FTWs have tremendous potential to remove the CIP from the water and its removal efficiency can be enhanced via immobilized bacterial augmentation strategies.
