Household biogas digester project

1.High rate Household biogas digester project
2.Low cost
3.No airtight test and maintenance
4.Solid organic waste

1. Introduction       PUXIN Household Household biogas digester project for wastetreatmentis composed of a 6 or 10 m3 PUXIN biogas plant, piperoutes, gas purify devices and gas appliances or small power biogasgenerator.      PUXIN Household biogasdigester project for waste treatmentismainly applied to farmhouseor domestic house to treat livestock waste, straw, human sewage andfood waste.      PUXIN Householdbiogas digester project for waste treatment has the flowingfeatures:      1.Easy and quick to bebuiltThe construction of PUXIN family size biogas system is exemptfrom the difficult airtight craft, so the technical difficulty isgreatly decreased, and the construction period is greatlyshortened. To build a Puxin Biogas Digester successfully, theconstructers are only required to master how to assemble anddisassemble the steel mould. Any workman can learn to build PUXINfamily size biogas plant within a day and with 100% successrate.     2. High reliableThe steel mould andthe glass fibre reinforced plastic gasholder can be mass-producedin factories, so that any place or country can build the PuxinBiogas Plant     3. Solid organic material(straw and grass etc.) can be used     4. Easyto maintainWhen the gasholder is leaking, the leak can be foundimmediately, and can be repaired on ground.    5.DurableThe concrete digester can last over 30 years, and the glassfibre reinforced plastic gasholder over 10 years. When thegasholder is worn out, a new one is replaceable, so that the biogasplant can last over 30 years.     6. Excellentsafety When the gasholder is taken out, no biogas is left in thedigester. The digester neck (1.5m in diam) is large enough to keepsufficient fresh air in the digester. So it is safe both to repairthe digester inside and to replace fermentation material . When thegas pressure reaches its limit, there will be automatic gas leak,hence no damage to the plant.     7. Lowcost  The Puxin Biogas Plant is composed of a concretedigester that is built with a steel mould provided by us, a glassfibre reinforced plastic gas-holder and a concrete or glass fibrereinforced plastic cover. The digester is 6 or 10 m3 of capacity.The gasholder is 1.6 m of diameter, 0.6 m of height and 1 m3 ofcapacity. 2. Flow chart      3.Construction process   4.
