Abstract
This research was done to ascertain the effect of variation of factors and parameters in biogas
production and their resultant effect in biogas yield. Co-digestion of pig and poultry dungs
were used as substrate for anaerobic fermentation. Nine plastic container of 4 liter capacity
were used to fabricate the bio-digester and hose used to connect them to wheelbarrow tubes
for gas collection. The lingo-cellulose (the co-digested mixture of pig and poultry) was
allowed to stay in the digester for 14 days pending when gas production will stop during
the batch culture fermentation. Bovine blood, MgSO4
and Charcoal water were used as
additives. For digester with blood, the cumulative gas production range for series 1, 2 and
3 are 0-74.4, 0-122.1 and 0-342.3 respectively. For the one with MgSO4, the range was
0-101.4, 0-180.7 and 0-262.3. For the last with charcoal water the range was 0-192, 0-290.3
and 0-373.3. The results shows that as the measure of the substrates as well as the additives
increases, the gas production increases. This research recommend that bovine blood which
contains nutrients; MgSO4
which increases catalyzes of the reaction and charcoal water
which increases the carbon content of reaction should be used in biogas production.
