Trends and Scope of Utilization of Biochar in Wastewater Treatment
AI summary Read the abstract
This review examined biochar as a low-cost, sustainable adsorbent for removing heavy metals, pharmaceuticals, pesticides, and microplastics from wastewater, comparing it favorably to conventional activated carbon. Developing effective, affordable filtration materials like biochar is critical for reducing microplastic concentrations in treated water before it reaches drinking supplies.
Heavy metals, organic matter, microplastics, pesticides, and pharmaceuticals cause severe pollution. Commercially available adsorbents can successfully adsorb them. Granular activated carbon (AC) is also an effective adsorbent with capacity to adsorb a large number...
