Biogas Blower Solutions for Digestion, Transfer & Renewable Energy Applications

A biogas blower is a positive displacement rotary blower designed to transport, compress or extract biogas generated from anaerobic digestion, wastewater treatment, agricultural waste, landfill fermentation, and industrial food‑processing residues. Because biogas is flammable and often corrosive, biogas blowers must be spark‑proof and highly reliable, especially in hazardous zones.

Biogas blowers supply, drive, compress, or extract biogas.

Different kind of industries use HIBON positive displacement blowers for the :

• agitation of digesters,
• transfer for supplying distillers, boilers, heat engines and generating sets, or systems of cogeneration...

Hibon has specially developed a range of biogas blowers. Blower systems must be explosion proof and with a high efficiency. Positive displacement Blowers are spark proof with ATEX configuration. Blower technology are frequent in this application, but we can find also multi staged centrifugal blowers.

It is a type of biofuel naturally produced from the decomposition of organic waste. It can be found in many areas of daily and industrial life. The process are often present:

• In agriculture with breeding excrements (animal manures), 
• from urban waste water treatment,
• from industrial food-processing,
• from the paper pulp production,
• from the fermentation of household disposal, food waste
• from landfill grounds,
• from waste treatment plants in digesters.
• from wastewater treatment plants

This long term decomposition happens in an anaerobic environment with absence of oxygen.

We refer to an anaerobic digestion. This gas is flammable. It is a blend of methane, carbon dioxide, and small quantities of other gasses.

Within the context of environmental protection applications, reduce methane emissions is in full development.

Effectively, it is an excellent source of clean energy. It has a lower impact on the environment than fossil fuels.

Biogas is produced by anaerobic decomposition of organic waste and consists mainly of methane and CO₂. It appears in numerous sectors: agriculture (manure digestion), wastewater treatment, food‑processing waste, paper pulp production, household waste fermentation and landfill gas extraction. A biogas blower ensures safe and efficient transport of this gas within each step of the process.

Agitation Of Digesters

The brewing by injection of compressed biogas is done at the base of the digester. 

We call this process a "gas bubble" or, more formally, "anaerobic digestion of biomass."

Positive Displacement blowers compress the gas from 1 to 2 bars depending on the height of the digester.

A frequency converter regulates often the pressure. Central distribution rods inject biogas at the digester’s base.

Biogas Transfer & Compression

A biogas blower is used to pull or push biogas for multiple downstream uses: supplying distillers, boilers, heat engines, gensets and cogeneration units. 

Safe transfer demands explosion‑proof design, a key advantage of Hibon’s ATEX‑compatible positive displacement technology.

We find this solution for any other combustible gas, such as: methane gas, or renewable natural gas from somewhere and deliver it to somewhere else for energy production.
