Fluoride Removal and Pollution Mitigation Using Rice Husk Biochar

Date: 21 Aug 2023

Country: India United States

Application

• Groundwater Remediation: Rice husk biochar effectively removes fluoride from contaminated groundwater, improving water quality.
• Sustainable Agriculture: Biochar enhances soil fertility, water retention, and drought resistance, benefiting agricultural productivity.

Description

This project focuses on using biochar made from rice husks to address air pollution and groundwater contamination. The biochar efficiently adsorbs fluoride ions from contaminated water, making it a promising solution for defluoridation. The study demonstrates the effectiveness of raw and modified biochar in removing fluoride from groundwater at a low cost. It also highlights the potential of biochar for sustainable crop residue management and climate change mitigation.

 

 

Pathway Description:

The project involves producing biochar by pyrolyzing rice husk at high temperatures in an oxygen-limited environment. The biochar is then modified to enhance its adsorption capacity for fluoride ions. Batch sorption experiments are conducted to test the effectiveness of both raw and modified biochar in removing fluoride from contaminated groundwater. The process focuses on optimizing biochar's efficiency for real-world applications in water purification.
