This innovative water purification technology leverages the adsorptive properties of biochar, a solid residue obtained from the pyrolysis of biomass, to remove contaminants from water. Designed to address the need for efficient and accessible water treatment methods, especially in emergency situations and extreme conditions, this technology utilizes various biomass materials as biosorbents. Its multifunctional nature allows for the effective remediation of emerging contaminants, offering a low-cost and environmentally friendly alternative to conventional water purification methods.
