“…Adsorption is a condition that occurs on the surface of a substrate. In the case of adsorption, it happens when the attraction force at the adsorbent surface overcomes the attractive forces of the liquid's dissolved substance [1]. Previous studies were done by other researchers related to the adsorption treatment method for removing pollutants from a food processing industry worldwide using agriculture-based waste that used as agent adsorbents, such as spent tea leaves, coconut shells, and rice husk, potentially used to remove concentration.…”

In the food processing industries, enormous amounts of water are utilized in the manufacturing process. Therefore, wastewater discharged from food industries must be characterized to develop viable treatment technologies. In this study, the adsorption method is used throughout the investigation and spent tea leave is used as a potential adsorbent to remove the concentrations of chemical oxygen demand (COD) and total phosphorus (TP). The synthetic wastewater sample containing COD, TP, suspended solids, and ammoniacal nitrogen was prepared to mimic the actual food processing wastewater as reported in the literature. The synthetic wastewater samples were formulated using analytical grade chemicals such as glucose anhydrous, sodium dihydrogen phosphate, kaolin, and ammonium chloride. The concentrations of the targeted parameters in the synthetic samples were first identified using the calibration curves. Then, this study was carried out in batch adsorption technique to determine the removal of COD and TP using varied adsorbent dosages between 100 mg/L to 500 mg/L. This study found that TP and COD were removed up to 75.04% and 15.5%, respectively, at the adsorbent dosage of 500 mg/L. Furthermore, the trend of TP and COD removals is increased as the adsorbent doses increased due to the availability of binding sites being higher at higher adsorbent dosage. Therefore, the results from this study suggest that spent tea leave has the potential to be used as an adsorbent to treat wastewater containing organic pollutants.
