Experimental design and set-up
Batch anaerobic digestion tests were carried out on chicken
droppings, mixture of chicken droppings and C. citratus, and C.
citratus alone in reactors AeC respectively. Prepared chicken
droppings (6 kg) were mixed with 500 ml of water to form slurry
was introduced into reactor A through an inlet pipe of 50 mm at the
top of the reactor. The synergy of the chicken droppings and the C.
citratus was done in the ratio of 1:1 by mass. Thus, 3 kg each of
prepared chicken droppings and C. citratus were synergized to give
a total mass of 6 kg of both. It was mixed with 500 ml water and was
introduced into reactor B through the 50 mm inlet pipe at the top of
the reactor.
