Biochar can alleviate several issues, and it should also be inexpensive to produce. Most biochars have a high pore structure and diverse functional groups that assist in the adsorption process. Due to the attributed properties of biochar, several studies have demonstrated that biochar is getting more attention for its efficiency in facilitating wastewater treatment. However, to ensure the feasibility of biochar in wastewater treatment, the factors involved in the preparation of biochar that influences its characteristics and adsorption capacity must be understood. This study reviews the history, characteristics, factors that influence its yield, production methods, application, and recent development of biochar in wastewater treatment.
