ABSTRACT

 

The aim of this research is to treat wastewater contaminants byreducing chemical oxygen demand (COD) concentrationusing adsorption process.This study investigated and optimized the effect of operating parameters to reachan ideal treatment by using alginate beads with entrapped activated carbon (AG-AC). The removal efficiency affected by(contact time,pH, CODconcentration,adsorbent dose, and stirring rate).The removal efficiencyof COD concentration was about(77and 89 %(after the adsorbent dose (30 g/L), pH (3), stirring rate (100 rpm), contact time (60min) and temp (25 ?C).The optimum operating parameters determined for increasing COD removal efficiency.
