Technology (page 1) |
 |
Anaerobic digestion treatment is a form of biological treatment
technology which uses naturally available anaerobic micro-organisms to
decompose organic matters into methane and carbon dioxide. During
industrialized operation, it consists of a gas-tight reactor that
creates an anaerobic environment to accelerate the growth of
micro-organisms under man-made conditions, so as to reach industrialized
production efficiency.
After anaerobic digestion, the organic matters in the waste can be
effectively converted into methane, which will be collected for heat
generation or thermal power generation.
Biomax is using single stage anaerobic digestion technology, with
various modes such as wet and dry digestion, thermophilic and mesophilic
processes. These modes will be effectively combined for optimal
treatment performance for different kinds of waste. |

Wet Anaerobic Digestion |
|
At Biomax we use Linde's wet anaerobic digestion technology. It is a
single stage anaerobic digestion technology consisting of a process with
a completely mixed reactor, in which the total solid content is between
8% and 15% . It features a pipe for gaseous circulation at the center of
the digester. Since the pollutants and inerts in the digestion residues
have been separated during the pre-treatment, the residues can be used
for the production of high quality organic fertilizers. This technology
is suitable for the treatment of waste oils from foods, sludge from
household sewage treatment plants, forestry and gardening waste, organic
waste etc. |

Dry Anaerobic Digestion |
The total solid content in the Valorga dry anaerobic digestion
technology is between 15 and 35 percent, ideal for treating complicated
waste such as gardening waste, organic waste, and mixed household
waste.This technology operates by injection of biogas from the bottom of
the digester into the digester to reach a mixing effect, thus the
digester does not contain any mechanical devices, saving time and costs
for maintenance.
In additional to the Valorga process, we also hold the license to
Linde's dry digestion process – the BRV process. The solid content
inside the digester ranges between 25% and 35%. This type of digester is
particularly suitable for small to medium anaerobic capacity projects,
i.e. for daily treatment capacity that exceeds 300 tons. The advantage
of BRV is that it is easy to construct and operate, which can lower
investment costs. |
