Minimal Maintenance Stainless Biogas Storage Tanks with superior corrosion resistance
The biogas storage tank is also called biogas holder and is a kind of Anaerobic digestion tanks that are often cone-shaped and supported at the center with a single pole. Commercial biogas reactor tanks are usually made from one of the following materials :
Among the above materials, the glass fused to steel is the perfect material for the biogas holder tank as comparison results as below

And what is glass fused to steel ( Enamel coating steel )?
After firing at 820°C-930°C high temperature, the molten glass
reacts with the steel plate surface to form an inert and inorganic
bond, which combines the strength and flexibility of steel and
outstanding corrosion resistance of glass.
The strong bonding enamel coating not only can prevent the
corrosion of the tank , but also resistance to strong acid and
strong alkali. To assemble the industrial tanks, we use the
self-locking bolt and special sealant to connect the steel sheets.
This kind of assembly structure achieved rapid low installation
requirements. And according to actual requirements, the capacity of
the tanks can be expanded and removed easily.
Application
GFS tank has been widely used municipal and industrial effluent, sewage, wastewater, water treatment as various aerobic and anaerobic reactors of UASB, EGSB, SBR, BAF, USR, CSTR, and equalization tank, sludge holding tank, etc. Detail application fields of the enamel coating tanks are as blow :
