In this work, the occurrence of contaminants in drinking water sources was described relation to their treatment options based on both conventional (e.g., coagulation-flocculation, sedimentation filtration, and chlorination) advanced techniques membrane ozonation, biofiltration). However, due apparent drawbacks these methods formation disinfection by-products (DBPs)), it is desirable develop an alternative option for safe water. respect, biochar recognized as effective candidate resolve limitations treating common pollutants typically occurring such microbial contaminants, inorganic heavy metals, volatile organic compounds (VOCs), pharmaceuticals personal care products (PPCPs), endocrine disrupting chemicals (EDCs). As can exhibit different types interactions with adsorbates, its sorption processes be explained by diverse mechanisms, e.g., π-π electron donor-acceptor interactions, complexation, precipitation, H-bonding, electrostatic attraction. light attractive features enhanced properties, cost-effectiveness, environmentally friendly nature), we offer in-depth discussion biochar-based technologies large-scale purification operation.HighlightsOccurrence various are discussed.Human health impacts exposure highlighted.Performances discussed.Potentials pristine modified biochars emphasized.Feasibility importance highlighted.
