Production
At Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), we
specialize in the design and manufacturing of high-quality
stainless steel tanks that are perfectly suited for Anaerobic
Digestion (AD) processes in biogas production. With over 30 years
of experience in the tank manufacturing industry, we are a global
leader in providing efficient, durable, and sustainable storage
solutions for anaerobic digestion systems. Our stainless steel
tanks are engineered to optimize the production of biogas while
ensuring the safety, durability, and reliability of the storage
system throughout its lifecycle.
The Role of Anaerobic Digestion (AD) in Biogas Production
Anaerobic digestion (AD) is a biological process where
microorganisms break down organic matter (such as food waste,
agricultural residue, or wastewater) in the absence of oxygen. This
process produces biogas, which primarily consists of methane (CH₄),
a renewable energy source. The biogas generated through AD can be
used for electricity generation, heating, or as a fuel source for
various industrial applications.
One of the key components of any AD system is the digestion tank,
where the organic material undergoes breakdown by microorganisms.
The efficient operation of these tanks is critical to maximizing
biogas yields and ensuring a sustainable energy output. That’s
where Center Enamel’s stainless steel tanks come in.
As a leading storage tank manufacturer in China. At Shijiazhuang
Zhengzhong Technology Co., Ltd., we excel in providing high-quality
bolted steel tanks tailored for the diverse needs of fish farming.
Our extensive range of bolted steel tanks includes
Glass-Fused-to-Steel (GFS) tanks, fusion bonded epoxy tanks,
stainless steel tanks, and galvanized steel tanks, each designed to
offer exceptional durability, efficiency, and adaptability for
aquaculture applications.

Why Stainless Steel Tanks for Anaerobic Digestion (AD)?
Stainless steel has become the preferred material for Anaerobic
Digestion (AD) tanks due to its exceptional performance
characteristics in the demanding conditions of biogas production.
Here's why stainless steel tanks are the ideal choice for AD
systems:
1. Superior Corrosion Resistance
AD systems create an environment that is both highly acidic and
anaerobic, which can quickly lead to corrosion and degradation in
lower-quality materials. Stainless steel provides exceptional
resistance to corrosion, ensuring that the tanks remain
structurally sound and functional for decades, even when exposed to
the harsh conditions inside a digester. SUS304 and SUS316L
stainless steel are commonly used in the manufacturing of AD tanks
due to their excellent corrosion resistance to hydrogen sulfide
(H₂S) and other biogas components.
2. Durability and Strength
Biogas production involves high pressure, temperature variations,
and mechanical stress due to the continuous movement and
interaction of organic matter in the digestion process. Stainless
steel tanks are extremely durable and strong, capable of
withstanding the physical stress and biogas pressure without
compromising their structural integrity. The strength of stainless
steel allows it to handle the heavy loads associated with
large-scale AD systems, making it the ideal material for
high-volume storage.
3. High-Temperature Resistance
During the anaerobic digestion process, temperatures can fluctuate,
and the organic material in the tank may become hot. Stainless
steel is capable of withstanding high temperatures without
deforming or losing strength. This makes it suitable for mesophilic
(moderate temperature) and thermophilic (high temperature)
digestion systems, ensuring that the digestion process remains
efficient, even under extreme conditions.
4. Hygienic and Non-Reactive Surface
Stainless steel’s non-porous surface ensures that it does not react
with the materials inside the tank, which is essential in a
biological process like anaerobic digestion. It is also easy to
clean and maintain, minimizing the risk of bacterial contamination
and ensuring that the conditions inside the digester remain optimal
for the breakdown of organic waste. This hygienic property of
stainless steel makes it a top choice for biogas plants focused on
maintaining sanitary conditions.
5. Longevity and Reduced Maintenance
Because stainless steel is resistant to corrosion, wear, and tear,
Center Enamel’s stainless steel tanks are built for long-term
durability. This low-maintenance solution reduces the costs and
downtime associated with tank repairs or replacements. The extended
service life of these tanks makes them a cost-effective investment
for any biogas production facility.
6. Environmentally Friendly
Stainless steel is a 100% recyclable material, which makes it an
environmentally responsible choice for biogas production. By
choosing stainless steel tanks for your AD systems, you're not only
ensuring efficient and safe storage of biogas but also contributing
to a more sustainable, circular economy. The durability and
recyclability of stainless steel contribute to a reduced
environmental impact throughout the tank's lifecycle.
Features of Center Enamel’s Stainless Steel Tanks for AD Systems
Center Enamel manufactures high-quality stainless steel tanks that
are specifically designed for anaerobic digestion processes in

Our tanks are leak-proof, ensuring that no biogas escapes into the
atmosphere. This is important for both environmental safety and
maintaining the energy output of the system. The high-strength
welds used in construction further enhance the integrity of the
tanks.
3. Internal Coatings for Enhanced Protection
In some cases, we offer internal protective coatings for stainless
steel tanks that provide an extra layer of protection against
aggressive materials present in the AD system, such as hydrogen
sulfide and ammonia. These coatings help to extend the lifespan of
the tank and enhance its resistance to corrosion and wear.
4. Customizable Tank Sizes
Our stainless steel AD tanks are available in various sizes and
configurations to suit the unique needs of your biogas production
facility. Whether you need a small digester for experimental or
pilot projects or a large-scale tank for a commercial biogas plant,
