Physical Characteristics and Oil Sorption Behavior of Fibers Derived from Oil Palm Empty Fruit Bunch Spikelets

Article Preview

Abstract:

This study examines the physical properties and oil sorption behavior of fibers extracted from the spikelets of Oil Palm Empty Fruit Bunch (OPEFB). The research begins with preparing spikelet fibers from OPEFB, followed by physical characterization testing, specifically surface morphology analysis, and concludes with oil absorption testing in Palm Oil Mill Effluent (POME). The findings reveal that spikelet fibers possess significant physical properties conducive to oil and grease adsorption, as evidenced by Scanning Electron Microscopy (SEM) and contact angle value. The adsorption efficiency achieved by spikelet fibers in removing oils and greases from POME reached an impressive 99%. The flow rate of the influent has a crucial role in determining the adsorption efficiency, with lower flow rates generally yielding higher efficiencies due to prolonged contact times. Notably, the use of spikelet fibers increased Soluble Chemical Oxygen Demand (SCOD) concentration to 2855 mg/L. This increment in SCOD can be attributed to the degradation of complex organic matter present in the empty fruit bunches. Overall, this research highlights the dual role of spikelet fibers in oil adsorption and the subsequent impact on water quality, suggesting the need for further investigation into their application in wastewater treatment.
