Gas formed in a tight tube (without oxygen) form a dome (Fixed-dome) with the help of methanogen bacteria, will produce a composition of methane (CH4) is greater than 60%, CO2 and little H2S. Biogas digester BD 7000L has the strength to withstand the pressure of gas to 5 kg/cm2 and have the staying power of the reactor 10 years. Made of fiberglass resin eternal 2504, mat Wr 200 (woven mat) and the mat 300 (random), the thickness of 3-5 mm, able to ferment 3 m3 per day of waste and biomass after the first cycle of decomposition of 27 days. Material input capacity of 7 m3 and 3.2 m3 fiberglass gas holder, has the dimensions (diameter 200 cm, height 390 cm), will last up to over 10 years and even up to 20 years. Installation BD 7000L will produce biogas pure> 80% methane (CH4) as much as 12.6 m3/day who has power and high calorie burning stove as the ingredient for cooking the equivalent of 5.79 kg of LPG.
