DOI Info:


In this study, different mix ratios of water hyacinth (WH) to poultry manure (PM) were digested and each experimental run was assessed over a period of 40 days in order to determine the best mix in terms of biogas yield. Water displacement method was used to measure the volume of biogas produced and the data obtained were analyzed using sigma plot non-linear parameter estimation model. The results showed that WH single-substrate digestion produced a cumulative gas volume of 32.18 L which corresponds to 5.14 L/kg of WH, while PM single-substrate digestion produced a cumulative gas volume of 209 L corresponding to 33.58 L/kg of PM. For the WH-PM co-digestion, the results revealed a range of 54.45 – 216.55 L with 2WH: 8PM recording the highest value of 34.65 L. 2 WH: 8 PM also had the highest biogas yield of 11.21 L/day and this was observed on the 18th day. The study revealed that the best mix of WH-PM co-digestion is 2 WH: 8 PM.
