Minimal Maintenance Stainless Biogas Storage Tanks
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 :
· Mild steel
· Concrete – Reinforced concrete and pre-cast (either pre-stressed or post - stressed)
· Stainless steel.
· LIPP
· Glass fused to steel: also called enamel coating steel, glass-lined steel.
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.
