BIOREMEDIATION OF POULTRY DROPPINGS FOR BIOGAS PRODUCTION

V. JEYANTHIKUMARI

Abstract

Bioremediation of poultry droppings for biogas production has become an important practice over the past several decades throughout the world because of it’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.
