Isma’il M. Chindo Gotomo,Zubairu U. Bashar, and Faruku A. Bagudu

ABSTRACT
Experimental investigations were carried out to investigate whether there is any effect on the digester size on the production of biogas with three different lactogen tins as digester sizes of 1 liter, 3 liters and 5 liters of 3 replicates each. From the result obtained, the production of biogas in the smaller digester of 1-liter size produced more gas than digester B of 3 liters and followed by digester C of 5 liters sizes, and record increased with increase in temperature and production decline with drastic fall of temperature. The average production of biogas was 8198.8cm3, 6140.5cm3, and 4043.8cm3 from digester A, B,and C respectively. The experiment run for 30 days with anaverage temperature of 31.90C, and records were taken at 12:00 noon from day one to last day of the experiment.
