The Anaerobic Suspended Growth Closed Bioreactor (ASGCB) was developed to generate bio-methane gas from the palm oil wastewater. The ASGCB offers high potential for rapid disintegration of organic matter to produce bio-methane gas that can be used to generate electricity. A significant amount of bio-methane gas is produced from the ASGCB for the treatment of palm oil wastewater. The ASGCB provides pilot scaled proved operational control in order to achieve optimal performance. Pilot scaled proved that the value of methane yield at 0.45 L CH4/ g CODreduction and 0.34 L CH4/ g CODreduction for thermophilic and mesophilic ASGCB are so far the highest methane yield for palm oil wastewater. The COD reduction efficiency of the thermophilic and mesophilic ASGCB was in the range of 90.90% - 83.58% and 89.66% - 79.83%, respectively, between the HRT 8 days and 24 days. The pH for both ASGCB were in the range of 8.05 to 7.74 and 7.80 to 7.35. High amounts of biogas were produced from 19.86 L biogas/day to 64.56 L biogas/day and 17.79 L biogas/day to 46.76 L biogas/day, respectively. The daily methane gas production were from 14.92 L CH4/day to 44.54 L CH4/day and from 12.92 L CH4/day to 30.81 L CH4/day, respectively, in the thermophilic and mesophilic ASGCB. The methane gas content ranged from 75.11 % to 68.99 % and 72.50 % to 65.90 % for both ASGCB. |
