The Puxin Biogas Digester is a fixed
dome-type medium-size biogas-digester for farms and other bio-waste
producing facilities. |

|
Description
The Puxin Biogas Digester has been developed in China. A country with a
long tradition in using the biogas technology.
For building the stomach and the neck of the digester we use a mould. This
mould is filled with concrete.
This way of construction guarantees precise fitting of the gasholder on
top. Within 2 days the digester is cast. The whole plant can be built
within 2 weeks. There are 3 sizes
of stomach (6 m3, 10 m3, and 14 m3) and 2 sizes of gasholders (900 litre and
1100 litre) available. JuaNguvu offers 2 types of Puxin Biogas
Digesters:
TN P standard
The standard system is a single stage biogas plant and can be operated
with any kind of manure (cow, pigs, etc), solid bio waste as well as
sewage.
TN P/2 biogas
system:
The P/2 biogas
system was developed by our engineers and is a 2-stage biogas plant. Its
additional features allow the use of solid bio waste (from kitchen, food
processing, vegetable markets, municipal (MSW), landscaping, etc) as
feedstock.
Characteristics:
- Low tech: The installation has only one electric component: a slurry
pump - no automated stirring devices, no heating systems, no electric
or electronic controls/valves.
- Low maintenance need: Thanks to the implementation of the hydrolysis
stage there are no solid material reaching the digester. This reduces
the maintenance of the digesters dramatically.
- Simple operation: For normal operation there is only one manual
valve to operate.
The many successful installation have proven the Puxin technology really "Fit for Africa".

Advantages
- The mould makes the digester easy and fast to build, thus saving
money.
- The use of the corrosion-free fibreglass gasholder and its unique
way of mounting on the digester neck guarantees tightness.
- The underground installation avoids any damage from the environment
thus reducing the maintenance to an absolute minimum.
- The material used and the way of construction guarantee a long lifespan and
therefore an easy payback.
- The Puxin Biogas Digester is a mature technology which has already
been installed in Kenya many times.
