This paper investigates the effects of variation in the inoculum to waste ratioon the anaerobic treatment of
slaughterhouse waste,and proposes a low cost anaerobic treatment system.The work was carried out using
a laboratory scale packed anaerobic digester with a gas collecting chamber.The inoculum used for seeding
there actors was septic tank sludge.The operating temperature ranged from 28 to 37
◦
C.The experimental
results indicated chemical oxygendemand(COD)removal efficiencies ranged from 60to90% and increased
with increasing inoculum to waste ratio beyond(1:1).The decrease in the temperature(from37to28
◦
C)
reduced the COD removal efficiency from 90to75%.The system didnot show any sign of destabilization
under intermittent mode of operation of the reactors.
