| Summary: | Malaysia's industrialization has resulted in water contamination, producing wastewater. In the foreseeable future, this issue is projected to get worse. Continuous adsorption by activated carbon (AC) in fixed-bed column offers an approach for resolving access to care challenges since it utilizes a low-cost adsorbent, generates minimal sludge, and is simple to deploy. This review paper focused on the influence of several factors on the continuous adsorption process in the fixed-bed column, such as the flow rate of methylene blue, initial methylene blue concentration, and the bed height of the column (BHC). The discussion of Thomas, Adam-Bohart, and Yoon-Nelson's models helps in the prediction of the breakthrough curve with the analysis of the R² values. With this, the factors that can help in the efficiency of continuous adsorption in a fixed-bed column can be determined. This review can aid in the wastewater treatment industries, particularly with the environmental-friendly adsorbents, and implement it in a large-scale application. |
