Summary:
Biochar-based filtration systems provide an effective solution for treating industrial wastewater in the energy sector, thanks to biochar's high surface area, porosity, and adsorption properties. This research explores using biochar to remove contaminants like heavy metals, organic compounds, and other pollutants from wastewater in energy production. Biochar, produced from agricultural waste via pyrolysis, is a sustainable and cost-effective filtration material that contributes to waste reduction and carbon sequestration. The study evaluates various types of biochar (e.g., activated, chemically modified) for their adsorption capacity, filtration rate, and longevity. Characterization of biochar is done using BET surface area analysis, SEM imaging, and X-ray diffraction to assess its suitability. Pollutants in treated wastewater are detected using ICP-MS for heavy metals and GC-MS for organic contaminants. The research also examines regenerating used biochar for repeated filtration cycles to enhance sustainability. The findings aim to demonstrate that biochar-based filtration systems provide an efficient, eco-friendly alternative to traditional wastewater treatment, reducing environmental impacts and operational costs.
