Potential of Epipremnum aureum in reduction of COD in industrial wastewater


Lee Shi Qing (2020) Potential of Epipremnum aureum in reduction of COD in industrial wastewater. Final Year Project thesis, Universiti Malaysia Kelantan. (Submitted)


Wastewater from industrial, agricultural, and urban activities is usually channelled directly into the streams. High chemical oxygen demand (COD) level in water indicated a vast amount oxidizable matter that consume a lot of dissolved oxygen in water. This results in adverse impacts on both aquatic ecosystems and human health. Wastewater from the fish cracker industry typically has high organic content and high COD value. In this study, Epipremnum aureum (E. aureum) was chosen in phytoremediation treatment because it is abundance and economical. This study emphasized on the optimum absorption parameters such as initial concentration of wastewater, retention time for treatment, initial COD concentration of wastewater and number of plants used in one treatment that affecting removal of COD in the wastewater. The wastewater's quality value was analysed and determined according to EQA standard thus considered as polluted. From the result, it was found that the highest percentage removal was 82.3 % with retention time of 10 days, initial wastewater sample with pH 6, initial COD concentration of wastewater sample of 75 % and treatment with 2 plants. Based on the study, E. aureum is proved to be a good COD removal plant.
