The construction and production of biomass digesters has become very important in recent years due to their wide advantages. A systematic study of different properties of the biogas and its amount provides us with a great deal of information about digesters. Thus the appropriate nature and type of digesters are suitable for different areas in Palestine. The experiment described in this work was carried out in Tulkami city in the northern part of Palestine. The floating drum type of digesters was used in this work. When the addition rate of slurry added on daily basis was 50 liters/day, the amount of biogas produced is 0.685 m³, the average pH is 7.91 and the average ambient air temperature is 34.055°C while for the 100 liters/day rate, the amount of biogas produced was 1.610 m m³ the average pH is 7.96, and the average ambient air temperature is 34.29°C. In both cases the slurry temperature was 27°C. Therefore, the possibility of making use of biogas as a source of energy in Palestine is promising and building more biogas digesters in Palestine is recommended.
