Macrocomposite effectiveness in the treatment of used water from the UTHM Pagoh Café

Abstract

This work aims to utilise a macrocomposite as an adsorbent to treat kitchen wastewater from the UTHM Pagoh café. The characteristics of kitchen wastewater were determined by measuring two parameters: suspended solid (SS) and chemical oxygen demand (COD). Because the macrocomposite was composed of zeolite, activated carbon, aggregate, and cement, it had a porous structure and a large surface area for adsorption. The flow rate of kitchen wastewater through the column was variable. At regular intervals, an effluent sample was collected. The flow to the column was maintained until the interval of 120 minutes had passed. The performance of the column was evaluated with flow rates of 50mL/min, 60mL/min, and 70mL/min. Using the Yoon-Nelson and Thomas models, experiment data was analysed. The collected and analysed data for both models indicate that a flowrate of 50 mL/min is optimal for wastewater treatment, with the highest R2 and adsorption capacity values.
