ABSTRACT |
The study was conducted to evaluate the effect of addition of food waste in brown water for anaerobic hydrogen production. Batch experiment was carried out to determine appropriate food waste to brown water mixing ratio. Maximum hydrogen yield of 6.92 mmol H2/g CODremoved was obtained at 70% food waste and 30% brown water. Semi-pilot scale reactor was operated based on result of batch experiment. Semi-pilot reactor operated, mixing 70% food waste and 30% brown water showed significant increment in butyric acid concentration. B/P (Butyric to propionic acid ratio) which is considered as governing factor for hydrogen production was found high (52.64). Maximum hydrogen yield of 25.03 mmol H2/g CODremoved was obtained. Result of this study concluded that mixing of food waste to brown water at appropriate ratio assists in enhanced hydrogen fermentation. |
