Characteristics of palm oil mill effluents (POME) from four localities in Côte d’Ivoire.

Parameters	Localities of palm oil production				Discharge effluent standards
Parameters	Aboisso^A	Sikensi^A	Divo^B	Zouan houien^B	Discharge effluent standards
pH	4.16 ± 0.47^a	4.11 ± 0.4^a	4.25 ± 0.13^a	4.74 ± 0.5^b	6.5–8.5
Total solids	62,460 ± 59^a	43,760 ± 108^a	134,880 ± 42.6^b	144,180 ± 49.7^b	–
Phenolics	264.1 ± 8.3^a	265.3 ± 5.3^a	441.7 ± 7^b	458.5 ± 14^b	0.3
Oil and grease	8,500 ± 33^a	28,950 ± 47.1^b	41,330 ± 52^c	42,750 ± 61.2^c	30
COD	ND	ND	ND	ND	300
BOD₅	ND	ND	ND	ND	100

All parameters are in mg/L except pH. Averages with the same letter on same line only for chemical characteristics are not significantly different by ANOVA (α = 0.05).

ND not determined.

^AIndustrial POME.
