Bolted Steel Anaerobic Digester Tank For Large Biogas Project
What Is Bolted Steel Anaerobic Digester Tank?
Bolted steel anaerobic digester tanks are made of individual sections including Glass-Fused-to-Steel, roof, tank ancillaries. All the individual sections of bolted steel anaerobic digester tanks are manufactured and finished in the factory according to strict structural specifications, with quality bends, welds and surface processing. The bolt holes and openings will be cut by CNC laser cutting machine automatically. Spray the glass coating on both sides of steel panels automatically. Coating thickness is controlled within 230 microns to 450 microns. After enameling and drying, then firing steel panels in the oven at the temperatures ranging from 850℃ -940℃, which facilitates the interfacial fusion reactions that combine the two materials. That is what we call Glass-Fused-to-Steel. Unlike field welded tanks, field welded tanks must be installed on-site, often resulting in imperfect and inconsistent finished coating, corrosion and other damage.
The anaerobic digester is a biological process to degrade and convert organic waste to biogas, which is widely used as a source in renewable energy. Almost all of the organic waste can use anaerobic digester, like domestic waste, industrial waste, animal waste, etc. These wastes can be highly utilized, convert the waste to the green renewable energy.

Why will you select our Bolted steel anaerobic digester tanks as an AD plant?
1. Super corrosion resistance: ART 310 the enamel specialize steel sheet, which is our patent in China, after enamel the ART 310 steel sheet greatly solves the fish scale problem. The PH of our steel sheet is from 3-11, for the special steel sheet it can be from 1-14, excellent acid and alkali proof function.
2. Suitable for various kinds of fields: Not only can be used as anaerobic digester, wastewater treatment plant, it also can be sued in power and energy, agriculture storage tanks.
3. Easy installed, expanded, dismantle, removed: The installation time of it is not only short, no need to use the big equipment as a concrete tank; but also the size can be expanded, easily dismantle and removed.
4. There is no weather, wind and site condition, the size is optional up to 18,000m3.
5. Our tank complies with international standards, which already passed the ISO9001-2000 system certification, and the design complies with AWWA D103 -09, OSHA, EN, and Australia standards. For the drinking water, our enamel frit also reaches the NSF61 standard.
5. We are the experienced manufacturer, we export tanks to the USA , Australia, Singapore, Malaysia, etc countries. Until now we install more than 2000 tanks all over the world and get good feedback from our customers.
