The family size biogas plant is mainly applied to farmhouse or domestic house to treat livestock waste, straw, human sewage and food waste.
The family size biogas plant is composed of a concrete biogas digester, pipe routes, gas purification devices and gas appliances ( stove, lamp, water heater, flow meter, room heater etc.) or small biogas power generator.
Steel mould with outer 10m³
It is composed of 93 steel mould boards and 19 work pieces, Tools and Mould Hooks.
It is composed of a container made with glass fibre reinforced plastic and three steel supports. On the top of the gas –holder there is a valve that can eliminate the atmospheric pressure.

1).Easy and quick to be built: The construction of the family size biogas plant 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 family size biogas plant within a day and with 100% success rate.
2).High reliability: The steel mould and the glass-fibre reinforced plastic gas-holder can be mass-produced in factories, so that any place or country can build the family size biogas plant.
3).Wide ferment material: All biogas waste includes solid organic material (food waste, straw, leaves and grass etc.) and liquid waste (wastewater, sewage, animal dung with water) can be fed to the biogas digester.
4).Easy to maintain: When the gasholder is leaking, the leak can be found immediately, and can be repaired on ground.
5).Durable: The concrete digester can last over 30 years, and the FRB gas-holder 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 feature: When the gas-holder 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).Money-saving: The family size biogas plant is built by concrete so its lifespan over 30 years and the steel mould can be used for many many times. Obviously it is more profitable than the membrane biogas digester at same price.
Puxin family size biogas plant built in Polytechnic University of Nicaragua to treat the food waste, the biogas for cooking.
Shenzhen Puxin Technology Co. Ltd. is a private enterprise founded in 2001. Since its establishment, the company has been concentrated in the development of Puxin biogas system and the products needed to build the system. After successfully completing the development of Puxin family size biogas system, the company began to develop of Puxin medium and large size biogas system in 2003.
In 2006, Puxin Biogas system won the “Blue Sky Award” granted by United Nations Industrial Development Organization and Shenzhen International Technology Promotion Center for Sustainable Development.
By the end of Sep. 2011, Puxin products for biogas development have been exported to nearly fifty countries as well as the international organizations UNDP, WFP and SNV. In China Puxin biogas system has been extended to over ten provinces.
