In order to improve the anaerobic fermentation of oil refinery wastewater (ORWW)
via an appropriate nutrients pool for microbial and buffer capacity growth, a study was carried
out on related anaerobic co-digestion (AcoD) with a rich organic carbon source, namely chicken
manure (CM). The kinetic parameters were investigated (including cumulative biogas production,
bio-methane content, retention time, and soluble chemical oxygen demand stabilisation rate) of
batch AcoD experiments related to six ORWW:CM-ratio treatments (5:0, 4:1, 3:2, 2:3, 1:4, and
0:5) under mesophilic conditions. The highest soluble chemical oxygen demand removal rate was
obtained for the 4:1-ratio treatment. However, the highest biogas production and bio-methane
contents were achieved for the 1:4-ratio treatment. When taking into consideration the highest oil
refinery wastewater portion in the AcoD mixtures and the statistical test results (LSD0.05) for the
kinetic parameters, it can be seen that the 4:1-ratio treatment provided the maximum biogas
production levels.
