“…This phenomenon was caused by the small size of EFB that were easily digested by the microbes. In the thermophilic phase of this study, the population of microbe colony was lower than that found in Ahmad et al's study [23] which obtained a microbial population of around 66 x 10 10 cfu/g, and then subsided to 9.0 x 10 10 cfu/g on 60 days of the composting. The decrease in composting temperature was followed by a decrease in the number of bacteria.…”

“…These values indicated that biosludge of pulp and paper had high organic matter. In comparison, the COD value in this study was lower than the anaerobic palm oil mill effluent that was obtained by Ahmad et al [23] where the COD valued 40,563 mg/l [23]. Meantime, the BOD value in this study was higher than in Baharuddin et al [10] which had a range between 1,000-2,600 mg/l.…”

“…The same support was provided by passive aeration from the perforated pipe in the composter, and this was helpful to expedite air circulation in the compost pile. Ahmad et al [23] had composted palm frond with a size of 0.2 to 0.5 cm, and led compaction in the compost pile structure, so that the performance of microbial activity and air distribution in compost declined. Tanpanich et al [34] regarded installation of twin horizontal perforated pipe as a provider of passive aeration in a compost pile was a better oxygen supply during the composting process [34].…”

The abundance of empty fruit bunches (EFB) is a result of many palm oil industries increasing their crude palm oil production. Composting is a good, environmentally friendly alternative to overcome EFB. Two different ratios of EFB with biosludge of pulp and paper of 1 : 1 and 3 : 2, respectively, were used in this composting. The particle size of EFB was set into three different sizes of 0.5; 1.5 and 2.5 cm. The best treatment that was obtained from this study was SR4 where the EFB particle size was 1.5 cm, and the ratio between EFB and biosludge of pulp and paper was 3 : 2, respectively. The nitrogen value of SR4 increased from 1.41% to 2.71%, and C/N ratio decreased from 36.74 to 12.17 in 90 days. The population peak of bacteria of SR4 in the thermopilic phase achieved about 33.67 x 1010 cfu/g. These two treatment combinations had shown an increase in EFB composting efficiency.

“…The composition of the Chromatiaceae in the system introduced with POME final discharge increased starting from day 2 (2.2%) to day 7 (5.1%), then reduced after the implementation of zero-emission of POME final discharge on day 8 (2.2%) and became undetectable on day 15. This can be explained by the association of Chromatiaceae composition with the degradation of dissolved organic carbon (DOC) present in the POME [58]. On the other hand, the composition of Alcaligenaceae showed a small reduction from 1.2% on day 8 to 0.9% on day 15.…”

Zero-Emission of Palm Oil Mill Effluent Final Discharge Promoted Bacterial Biodiversity Rebound in the Receiving Water System

et al. 2021

Zero-emission technology for palm oil mill effluent (POME) has led to a breakthrough in the palm oil industry in relation to the goal of sustainable development. However, there are limited resources on how this technology has affected the bacterial community in the receiving river that has previously been polluted with POME final discharge. Thus, the current study assessed the recoverability of the unexplored bacterial community in the receiving water of a constructed river water system post-zero emission of POME final discharge. An artificial river water system was constructed in this study, where the viability status and the composition of the bacterial community were assessed for 15 days using a flow cytometry-based assay and high-throughput sequencing by Illumina MiSeq, respectively. The zero-emission of POME final discharge reduced not only the physicochemical properties and nutrient contents of the receiving water, but also the bacterial cells’ viability from 40.3% to 24.5% and shifted the high nucleic acid (HNA) to low nucleic acid (LNA) content (38.7% to 34.5%). The proposed POME bacterial indicators, Alcaligenaceae and Chromatiaceae were not detectable in the rainwater (control) but were detected in the artificial river water system after the introduction of POME final discharge at the compositions of 1.0–1.3% and 2.2–5.1%, respectively. The implementation of a zero-emission system decreased the composition of Chromatiaceae from 2.2% on day 8 until it was undetectable on day 15, while Alcaligenaceae was continuously reduced from 1.2% to 0.9% within that similar time frame. As indicated by principal coordinate (PCO) analysis, the reductions in biological oxygen demand (BOD5) would further diminish the compositions of these bioindicators. The zero-emission of POME final discharge has demonstrated its efficacy, not only in reducing the polluting properties, but also in the bacterial biodiversity rebound in the affected water system.
