This study focuses on optimizing the decolourisation process of Palm Oil Mill Effluent (POME) by employing treated coal bottom ash as an efficient adsorbent. Coal bottom ash, treated through a tailored process, demonstrates enhanced capabilities for removing colorants from POME. The experimental investigations involve assessing the influence of adsorbent dosage, contact time, and pH on the decolourisation efficiency. The results reveal a significant improvement in POME decolourisation, underscoring the potential of treated coal bottom ash as a sustainable and effective adsorbent for the remediation of POME.
