Optimization of operating parameters in microbial consortium (AB-101) preparation and application in palm oil mill effluent (POME) primary treatment
Polluting characteristics of palm oil mill effluent (POME) urge palm oil mills to implement numerous technologies to further treat POME after the primary treatment system to comply the effluent discharge standard limit posed by Department of Environment (DOE) Malaysia. However, microbial consortium...

Polluting characteristics of palm oil mill effluent (POME) urge palm oil mills to implement numerous technologies to further treat POME after the primary treatment system to comply the effluent discharge standard limit posed by Department of Environment (DOE) Malaysia. However, microbial consortium (AB-101), a dark-brown liquid fermented product of various type of fruits and plants was introduced to improve the conventional biological treatment process in order to comply the standard without tertiary treatment. It is mixed with selective nutrients and effluent to prepare end product (bio-activator) that is inoculated into anaerobic ponds of POME to enhance anaerobic digestion. Therefore, the purpose of this research is to evaluate and optimize the operating parameters in microbial consortium (AB-101) application, such as; (i) volume percentage of AB-101 in bio-activator preparation process; (ii) volume percentage of molasses in bio-activator preparation process molasses; and (iii) dosage of the bio-activator.
