Abstract
Bioremediation of poultry droppings for biogas production has become an important practice over the past several decades throughout the world because of itââ¬â¢s beneficial effects. In the present study the gradual replacement of cow dung with poultry droppings and sewage water (20.%, 40%, 60%, 80% & 100% respectively) in the interval of 15 days for biogas production was carried out in KVIC model bioreactor at 10% total solid concentration in a semi continuous mode of anaerobic digestion bioreactor. Replacement of cow dung with poultry droppings resulted in the enhancement of biogas production especially in 100% replacement of cow dung with poultry droppings. Nitrogen, phosphorus and potash content of the effluent also improved. A control bioreactor was also maintained which consists of equal amount of cow dung with ordinary water.
