Palm oil mill effluent (POME) was identified to give significant contribution in polluting
the environment. In this study, new safe and environmentally friendly method using
eco-enzyme has been prepared to be used during pre-treatment stage of POME. Ecoenzyme
is the fermentation product of pre-consumer supermarket residues (orange,
pineapple, mango dregs and tomatoes), brown sugar and water. The effective
treatment time for POME was determined using batch process for the duration of 10
days by using varying concentration of enzyme solution. Eco-enzyme solution of
(10%) was found more effective in treating POME and the best treatment time starts
from the seventh day and above where it could reach almost 50% removal of BOD,
COD and oil and grease. Results showed that exactly 90% of oil and grease could be
removed by using eco-enzyme solution. Hence, eco-enzyme could be an alternative
method in treating waste water as it is cheaper and environmentally friendly.
