Energy Recovery: Agricultural Waste Anaerobic Digester Tank
description
Anaerobic digestion of agricultural waste mainly uses agricultural and forestry waste such as straw, livestock and poultry manure, fruit and vegetable waste, rice husks, and slaughtering by-products as raw materials. Open-air storage of manure, straw, and rotten fruits and vegetables reduces odor and leachate pollution of soil and groundwater. Anaerobic digestion can decompose organic matter in waste into biogas, protecting the environment and recovering new energy sources.
GFS enamel tanks have excellent resistance to acid and hydrogen sulfide corrosion, which are the top choice for anaerobic digestion.
Material Characteristics of Glass-Fused-to-Steel Tanks
-Low Carbon, High Strength, High Titanium.
The steel substrate employed in the construction of glass-fused-to-steel tanks is a special high strength enamelled steel with a unique design and superior properties. Its mechanical properties, including yield strength, tensile strength, and elongation, far exceed those of conventional steel sheets.

Advantages
Advantages of GFS Enamel Tank for Agricultural Waste Anaerobic Digestion
● Superior resistance to organic acid & H₂S corrosion, perfectly fit variable pH from manure & straw digestion. In particular, the 3-coat 3-baking enamel glass glaze layer is resistant to acids and alkalis and oxidation corrosion, which is far superior to ordinary carbon steel corrosion inhibitors and cement pools, and the inner wall will not rust or leak.
● Smooth vitreous lining prevents sludge adhesion and scaling, reduces mixer load.
● Excellent gas tightness to minimize biogas loss, compatible with top integrated double membrane gas holder.
● Convenient thermal insulation for stable mesophilic digestion and lower heating cost.
● Pre-fabricated panels, fast on-site assembly, expandable and relocatable.
● Service life over 30 years with low maintenance cost.
Agricultural Waste Anaerobic Digestion
● Pollution control: Eliminate odor, groundwater pollution and straw open burning.
● Energy recovery: Produce biogas for heating, power generation or biomethane.
● Digestate recycling: Fermented slurry & residue as organic fertilizer for farmland.
● Circular economy: Realize crop-livestock recycling & carbon emission reduction benefits.
