PUXIN organic waste treatment biogas digester for household treatment
PUXIN Household Household biogas digester system for waste treatmentis composed of a 6 or 10 m3 PUXIN biogas plant, pipe routes, gas purify devices and gas appliances or small power biogas generator.
PUXIN Household biogas digester system for waste treatmentismainly applied to farmhouse or domestic house to treat livestock waste, straw, human sewage and food waste.
PUXIN Household biogas digester system for waste treatment has the flowing features:
1.Easy and quick to be built
The construction of PUXIN family size biogas system is exempt from the difficult airtight craft, so the technical difficulty is greatly decreased, and the construction period is greatly shortened. To build a Puxin Biogas Digester successfully, the constructers are only required to master how to assemble and disassemble the steel mould. Any workman can learn to build PUXIN family size biogas plant within a day and with 100% success rate.
2. High reliable
The steel mould and the glass fibre reinforced plastic gasholder can be mass-produced in factories, so that any place or country can build the Puxin Biogas Plant
3. Solid organic material (straw and grass etc.) can be used
4. Easy to maintain
When the gasholder is leaking, the leak can be found immediately, and can be repaired on ground.
The concrete digester can last over 30 years, and the glass fibre reinforced plastic gasholder over 10 years. When the gasholder is worn out, a new one is replaceable, so that the biogas plant can last over 30 years.
6. Excellent safety
When the gasholder is taken out, no biogas is left in the digester. The digester neck (1.5m in diam) is large enough to keep sufficient fresh air in the digester. So it is safe both to repair the digester inside and to replace fermentation material . When the gas pressure reaches its limit, there will be automatic gas leak, hence no damage to the plant.
7. Low cost
The Puxin Biogas Plant is composed of a concrete digester that is built with a steel mould provided by us, a glass fibre reinforced plastic gas-holder and a concrete or glass fibre reinforced 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 of capacity.
