Biochar-bacterial composite

Application

  • Wastewater Treatment: Effective removal of lead and phenol from contaminated water using biochar-bacterial composites.
  • Environmental Remediation: Sustainable solution for detoxifying organic and inorganic pollutants in industrial effluents.

Description

This study explores the bioremediation potential of biochar composites made from sunflower seed husk and rice straw, hybridized with a bacterial consortium (Proteus mirabilis and Raoultella planticola) to remove lead and phenol from wastewater. Kinetic experiments demonstrated that these composites removed lead and phenol more effectively than individual components. The bioremediation process was evaluated using four kinetic models, with Fractional Power and Elovich models showing the best fit. The results highlight the synergistic effect of biochar and bacterial consortium in detoxifying both organic and inorganic pollutants.

 

 

Pathway Description:

The study involved producing biochar from sunflower seed husk and rice straw and immobilizing a bacterial consortium (Proteus mirabilis and Raoultella planticola) onto the biochar. These biochar-bacterial composites were used to remove lead and phenol from synthetic wastewater. Kinetic experiments were performed to evaluate the effectiveness of the remediation process. Several kinetic models, such as Fractional Power and Elovich, were applied to analyze the adsorption dynamics.
