Anaerobic Digestion & Biogas
Humidity, temperature and corrosion resistance against toxic gases and moist air
Fans for Anaerobic Digestion & Biogas Production
The risk of explosion or corrosion from toxic gases and moist air respectively, means that components within environmental systems such as anaeobic digestion must be corrosion resistant and manufactured from suitable materials that can handle the aggressive nature of the fumes generated in the environment. For example, corrosion resistant polypropylene fans should be used to exhaust biogas from the digestor to the combined heat and power engine to enable safe and effective processing.
REDUCING FAN CORROSION IN ANAEROBIC DIGESTION
Aggressive chemicals produced during the anaerobic digestion process attack steel and material corrosion can set in very quickly. If a fan, for example, starts to develop signs of rusting, processes such as welding are out of the question due to the high concentrations of combustible methane and carbon dioxide gases that can be readily ignited by a simple welding spark. Equally, the fermentation and oxidation processes used by digestors, whether concrete or steel, create the perfect environment for corrosion both at the liquid and gas stage, while sludge tanks face similar challenges.

Carbon Loaded ATEX Certified Corrosion Resistant Fans
Where ignition risks occur due to the increase in flammable gases or combustible materials, ATEX certified fans mitigate the risk of explosions by reducing ignition sources. Carbon loaded UV stabilised polypropylene ensures static electricity is conducted effectively, reducing the risk of spark ignition when mixed with the potentially hazardous environment created during the AD process.
High Pressure Fume Extraction Fans
Reduce the risk of fan component corrosion caused by toxic gases and moist air respectively, with corrosion resistant materials that can handle the environment conditions. Non corrosive polypropylene fans are used to extract, move and exhaust biogas from the digestor to the combined heat and power machines in AD processes, to enable safe and effective processes.

Biogas technology can supply 30% of the UK's domestic gas demand
reducing methane emissions and tackling the climate crisis.
Anaerobic digestion and biogas technology can supply 30% of the UK’s domestic gas demand. That is the degree of importance that the Worlds industry trade organisation ADBA placed on the ability of a fully supported UK biogas industry back in 2015. The process is now a continually important area of focus as the initiative can reduce CO2 emissions, provide a wide range of post COVID employment opportunities for city and rural occupants, produce low carbon energy 24/7 and provide a resource to fertilise land and reduce polluting farm run off. According to David Newman, President of the World Biogas Association, “If we do not address methane emissions from organic waste, all our efforts to tackle the climate crisis will fail. AD is one of those ready to go, ready to scale technologies, the path we take is clear”. Biogas is the main desirable product from anaerobic digestion of organic carbon. The key to small scale digestion is generating and utilising the energy on site to help to meet our 2023 targets as set by the Government.
