Production Of Biogas By Using Air Stripping As Pre-Treatment Process In Anaerobic Digestion Of Palm Oil Mill Effluent (POME)

This study aims to produce biogas from palm oil mill effluent in anaerobic digestion through the pre-treatment of the air stripping process. Air stripping is the process of moving air through contaminated water with volatile contaminants in a treatment system above ground. The air movement process c...

Civil engineering (General) This study aims to produce biogas from palm oil mill effluent in anaerobic digestion through the pre-treatment of the air stripping process. Air stripping is the process of moving air through contaminated water with volatile contaminants in a treatment system above ground.

One of the bottles will undergo an air stripping pre-treatment process while another glass bottle will be used as a control for an anaerobic digestion process without pre-treatment. Air stripping pre-treatment will be conducted using an airflow rate of 4L/min for 1 to 4 days. The treated POME will be tested for its ammonia nitrogen content and the results of the parameter test before and after the air stripping pre-treatment process will be compared. After the pre-treatment process, POME will undergo anaerobic digestion for biogas production. A glass bottle containing treated POME will be connected with a nalophan bag.
