What does this research mean for the field?

The wastewater treatment plant at PT Bintara Tani Nusantara reduces BOD5 and oil/grease in Palm Oil Mill Effluent but fails to achieve compliance with regulatory discharge limits for BOD5, COD, and total nitrogen. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To conduct a preliminary assessment of a palm oil mill wastewater treatment plant's discharge compliance, nearby surface water and groundwater quality, and embankment soil properties.

To conduct a preliminary assessment of a palm oil mill wastewater treatment plant's discharge compliance, nearby surface water and groundwater quality, and embankment soil properties.
Conducted a single-event sampling of wastewater at the plant inlet (sludge pit) and outlet (buffer pond), one community groundwater well, and three surface water locations in West Sumatra, Indonesia.
Analyzed water samples for biochemical oxygen demand (BOD5), chemical oxygen demand (COD), oil and grease, and total nitrogen, combined with direct shear and moisture content soil testing across nine embankment points.
Influent exhibited high levels of BOD5 (10,155 mg/L), oil/grease (3,044 mg/L), total nitrogen (1,118 mg/L), and elevated temperature (46.2°C), though the reported influent COD (51.4 mg/L) was flagged as an anomaly.
Treated effluent concentrations decreased to 303 mg/L for BOD5 and 2.2 mg/L for oil/grease, yet effluent remained non-compliant with regulatory limits for BOD5, COD, and total nitrogen.
Surface water screening showed low BOD5, with COD (<9.91 mg/L) and oil/grease (<0.345 mg/L) below detection limits.
