Food Waste Anaerobic Digestion Enameled Tanks from China Suppliers - Factory Assembled Biogas Solutions
Description
Food waste is characterized by "four highs": high water content, high organic matter content, high oil content, and high salt content, as well as its unique properties of being easily perishable and easily acidified. These characteristics directly determine the technological difficulty and equipment selection requirements in anaerobic fermentation treatment (which is why enamel bolted tanks need to have extremely strong corrosion resistance and sealing performance).
Glass fused to steel is a permanent, molecular bond created by fusing a specially formulated silica-based glass enamel to a base sheet of steel at very high temperatures (around 820°C / 1500°F), combines the advantages of both materials -- the strength and flexibility of steel and excellent anti-corrosion properties of glass.

In response to the characteristics of food waste being high in oil, salt, and organic matter, this enameled bolted tank has the following advantages:
-
1. Strong corrosion resistance
The porcelain glaze has a smooth, chemically inert surface, which can resist long-term corrosion from the high concentrations of organic acids and hydrogen sulfide produced during food waste fermentation.
-
2. Excellent sealing
Bolted connections combined with specialized sealant effectively maintain the anaerobic environment inside the tank, preventing oxygen infiltration and ensuring the activity of methanogens.
-
3. Flexible construction
Installation is less affected by weather and has a short cycle. It can be flexibly customized according to project scale, and can be easily expanded, disassembled, or relocated after completion.
-
4. Long service life
The enamel coating is wear-resistant and aging-resistant, and its designed service life is typically over 30 years.
-
5. Integrated Design
The tank top can be integrated with a double-membrane flexible gas holder, realizing integrated fermentation gas production and storage, saving space.
Frequently Asked Questions
Food waste features "four highs": high water content, high organic matter content, high oil content, and high salt content. It is also highly perishable and easily acidified.
Anaerobic fermentation of food waste produces high concentrations of organic acids and corrosive gases like hydrogen sulfide. Tanks must have strong corrosion resistance to withstand this aggressive environment without degrading.
Glass-Fused-to-Steel is a technology where silica-based glass enamel is fused to a steel base sheet at temperatures around 820°C (1500°F). This creates a molecular bond combining the structural strength of steel with the chemical inertness of glass.
The standard grade GFS tank supports a pH range of 3 to 11, while the special grade supports a pH range of 1 to 14. The designed service life is typically more than 30 years.
The tank utilizes high-precision bolted connections combined with specialized sealants to create a hermetic seal, maintaining a strict anaerobic environment and preventing oxygen infiltration.
Yes, the tank top is designed to integrate with a double-membrane flexible gas holder, allowing for simultaneous fermentation and biogas storage to optimize space usage.
