Abstract

ABSTRACT Palm oil mill effluent (POME) contains high amounts of organic matter, potentially as a source of environmental pollution. The processing of POME in anaerobic ponds is produced by biomethane, which is a greenhouse gas and also is a potential as a renewable energy source. Indonesia is the world’s largest CPO producer, but POME processing is still mostly done by conventional methods without methane capture. In this system, the value of methane emitted into the atmosphere is unknown. This research focused on estimating the methane emissions in anaerobic ponds (AP) multiple feeding wastewater treatment plants (WWTPs) for land applications, with CH4-meter systems based on TGS2611 sensors, SHT11 and microcontrollers, and using closed static chambers. The sampling of wastewater and methane gas was carried out in October-November 2018. The results showed that the methane gas emissions in combined anaerobic ponds (AP2-AP1) and AP3 were 43,704 and 35,321 mg/m2/day respectively, and a total of 405.358 and 61.812 kg/day sequential on AP2-AP1 (9,275 m2) and AP3 (1,750 m2). It was obtained from the correlation between methane emissions with removed COD as a conversion coefficient of 0.2107 kg CH4/kg COD removed. On the basis of linear regression with R2 0.9725, it was still below the theoretical value (stoichiometry) of 0.25 kg CH4/kg COD removed. From the conversion coefficient, COD removed, and the amount of POME in 2018, which was 104,179 m3, contributed to emitting 462 tons of methane from the entire anaerobic pond. This conversion coefficient can be used to quickly estimate the methane emissions in Indonesian palm oil mills
