Abstract

The population growth rate has been demonstrated to have a direct impact on the increase in pollutant concentrations released into water bodies. One of the pollutants that has been identified in water bodies is congo red. This necessitates the implementation of effective management strategies to mitigate the adverse effects of pollutants. A methodology that has been demonstrated to be effective in mitigating the impact of congo red is the coagulation-flocculation process. The objective of this study is to employ biocoagulants and magnetic biocoagulants derived from moringa oleifera as mass separation agents to mitigate the adverse effects of congo red. The effectiveness of the mass separation agents was evaluated with varying initial concentrations of congo red. The augmentation of the initial congo red concentration yielded consistent results for both biocoagulants and magnetic biocoagulants. The highest results were obtained at an initial congo red concentration of 100 ppm, with a value of 97.34% for the magnetic coagulant. The coagulation-flocculation process can occur through several mechanisms, including charge neutralization, floc formation, and sedimentation.

Abstract

The release of dyes into the environment can have deleterious effects. therefore, their handling must be done in a conscientious manner. One method that can be employed is coagulation-flocculation. The employment of natural coagulants has been demonstrated to mitigate the deleterious effects of polluting compounds on the ecosystem. Moringa oleifera, a plant native to tropical regions, including Indonesia, is a natural source of coagulants. Moringa oleifera plants are extracted using sodium chloride to isolate protein active ingredients. The utilization of a natural coagulant derived from moringa oleifera was implemented with the objective of ameliorating the deleterious effects of congo red. The effectiveness of the natural coagulant was evaluated based on the effect of initial concentration and coagulant dosage. The initial concentration and dose of coagulant exhibited a direct correlation with the efficiency of reducing congo red. An increase in the initial concentration resulted in a concomitant decrease in efficiency, while an increase in the coagulant dose demonstrated a corresponding increase in efficiency. The highest removal efficiency value was obtained when the coagulant dose was 100 ppm and the initial concentration was also 100 ppm. The consequence of this condition was a 99.46% reduction in efficiency of the congo red.
