摘要：Kitchen wastewater that is discharged to the environment is one of the contributing factors to waterpollution in Malaysia and other developing countries. Various techniques have been employed toremove the pollutants namely, physical, chemical and biological treatment. Biosorption is one of thebiological treatments that has emerged as a new technology for the removal and recovery of pollutants,which is more environmental friendly. This study focuses on the effectiveness of the kitchen wastewatertreatment systems using low-cost natural fibre of banana trunk (Musa sapientum) as biofibre toremove COD, ammonia nitrogen, suspended solids, turbidity, colour, and oil and grease from kitchenwastewater. The optimum adsorption capacities of banana trunk biofibres were investigated underseveral conditions, namely, pH, absorbent dosage, speed and contact time. The optimum pH wasfound to be 6. The experimental results obtained were satisfactory at a dosage of 2 g at 150 rpm. Thebanana fibres show satisfactory COD removal of 88%, ammonia nitrogen of 84%, suspended solidsof 83%, turbidity of 75%, the colour of 67% and oil and grease of 68% respectively. Maximum removalwas achieved at 2 hours contact time. The study reveals that the banana fibres could be acceptablefor efficient removal of organics and nutrients present in the kitchen wastewater.
