  • Specification: 156 x 120 x 195 cm
Puxin biogas units perform anaerobic digestions. Anaerobic digestion is the breakdown of organic material by micro-organisms in the absence of oxygen. It produces biogas, a methane-rich gas that also contains carbon dioxide with trace amounts of other gases; and digestate, a source of nutrients that can be used as a fertilizer. The digestion process begins with bacterial hydrolysis of the input material in order to break organic polymers into smaller molecules that finally become methane and carbon dioxide after acidogenesis and methanogenesis. Standard equipment:
  • Portable Assembly Membrane Digester 3.4 CBM
  • Biogas pump 220 V AC 15 W
  • Biogas desulfurizer PX-1 L, filter of size 1 L
  • Biogas Fitting
  • Stainless steel sink
  • Stainless steel outlet
  • Hollow sunlight sheet greenhouse
  • Nominal gas pressure: 0.12 bar
  • Power of biogas booster pump: 15 W
  • Minimum Ambient Temperature: 10 °C
  • Waste capacity: Food waste 25 kg/d; Pig manure 45 kg/d; Cow manure 60 kg/d; Chicken manure 26 kg/d; Human manure 32 kg/d; Vegetable 65 kg/d

Product Schematics

Technical Support

Supported by Puxin. Installation and operation manuals available upon request.interview with representative

Replacement Components

Some of the components replaced by the manufacturer are the feeding pump, circulating pump, and membrane digester.


Over 10-year lifetime with a 1-year warranty against manufacturing defects

Manufacturer Specified Performance Parameters

This plant was designed to make gas production efficient, be convenient for transport, and easy to install.

Vetted Performance Status

Testing of the product was done by Shenzhen USG Labs, the verdict was that the biodigester is capable of converting organic waste into biogas.


Extreme caution is necessary when working with biogas. Adequate ventilation, appropriate precautions, good work practices, and adequate personal protective equipment will minimize the dangers associated with biogas. Biogas storage & production bag is made of macromolecular structure polylayer design, therefore there is no leaking risk.

Complementary Technical Systems

Other related products can be added - not included in the unit price: 1. Feeding pump for sewage sludge disposal 2. Circulating pump for raw material feeding and anaerobic digestate mixing 3. Grinder for food waste shredding 4. Electric heater can be added for cold regions 5. Biogas stove, biogas rice cooker, biogas generator, etc 6. Biogass Lamp

Compliance with regulations

The product has the ISO 12100 certification

Evaluation methods

Each digester will be installed and inspected after manufacturing. Before sending it to Puxin, the factory will conduct a second inspection. Once the product has arrived at the company, the company’s technicians also need to install and check again.Interview with representative

Other Information

Special size products can be manufactured when ordered in batch.
