Overview

Randomized trial evaluates brewery-waste biochar for antibiotic removal, indicating improved treatment effectiveness.

Key Points

  • The study aims to evaluate the effectiveness of malt bagasse biochar in removing levofloxacin from wastewater using various treatment methods.
  • Batch adsorption experiments were conducted to assess levofloxacin removal capacity.
  • Fixed-bed columns and a biological activated carbon (BAC) column were utilized for tertiary treatment evaluation.
  • Kinetic and isotherm models were employed to analyze data and estimate key parameters.
  • MB biochar achieved a maximum levofloxacin adsorption capacity of 2.96 mg g⁻¹ after approximately 4,880 min.
  • BAC column removal rate reached 22.6%, significantly higher than the 10-12% achieved by biochar alone.
  • Microbial analysis showed dominance of Burkholderia (65%) within the BAC biofilm, linked to antibiotic transformation.
