Center Enamel Provides Anaerobic Digester Tanks For Switzerland
Wastewater Treatment Project
As climate change continues to dominate the global discourse,
countries around the world are investing in sustainable and
energy-efficient technologies. Switzerland, a pioneer in
environmental conservation and renewable energy, is advancing its
wastewater treatment initiatives by focusing on biogas production
through anaerobic digestion. In support of this environmentally
strategic effort, Shijiazhuang Zhengzhong Technology Co., Ltd
(Center Enamel) proudly offers high-quality, durable, and
internationally certified anaerobic digester tanks designed for
modern wastewater treatment facilities across Switzerland.
With over 30 years of experience and a global reputation for
quality and innovation, Center Enamel is uniquely positioned to
support Switzerland in its transition to a low-carbon economy. Our
anaerobic digester tanks, especially our renowned
Glass-Fused-to-Steel (GFS) tanks, offer a perfect combination of
strength, corrosion resistance, and cost-efficiency.

28765, NSF/ANSI 61, WRAS, FM, CE/EN1090, AWWA D103, and more. We
have successfully completed projects in over 100 countries,
including the USA, Germany, Australia, Brazil, Malaysia, Russia,
South Africa, and now expanding further into Central Europe.
Switzerland's Commitment to Sustainable Wastewater Treatment
Switzerland’s environmental policies emphasize carbon neutrality,
renewable energy generation, and circular waste management. One of
the most effective strategies in achieving these goals is the use
of anaerobic digestion in wastewater treatment plants.
Anaerobic digestion converts organic waste into biogas—a renewable
source of energy—and nutrient-rich digestate for use as fertilizer.
This method is especially effective for municipal and industrial
wastewater treatment facilities, agricultural waste systems, and
landfill leachate plants.
With many Swiss municipalities upgrading their wastewater
infrastructure to include biogas recovery systems, the demand for
durable and efficient anaerobic digester tanks is on the rise.
Center Enamel's GFS anaerobic digesters are perfectly suited to
meet this demand.
Advantages of Center Enamel's GFS Anaerobic Digester Tanks
Superior Corrosion Resistance
Our tanks combine the mechanical strength of steel with the
chemical resistance of glass. The Glass-Fused-to-Steel technology
fuses glass to steel at high temperatures (820°C-930°C), creating a
chemically and physically bonded surface that resists acids,
alkalis, and microbial activity.
Long Service Life
Center Enamel's tanks have a service life of over 30 years. With
minimal maintenance required, the total cost of ownership is
significantly reduced, making our tanks a smart long-term
investment for Swiss wastewater authorities.
Gas and Liquid Impermeability
GFS tanks are designed to be completely sealed, ensuring high gas
tightness critical for efficient biogas production and containment.
Wide Operating pH Range
Our tanks can operate in environments with a pH range of 1 to 14,
accommodating a variety of waste compositions and digestion
processes.
Fast Installation and Modular Design
The bolted design allows for fast and efficient on-site
installation, even in remote or constrained areas. This reduces
construction time and labor costs.
Customizable Sizes and Components
We offer a wide range of sizes (20 m³ to 60,000 m³) and
configurations. Optional accessories include mixers, insulation,
manways, domes, ladders, and platforms—all tailored to meet the
specific needs of Swiss biogas projects.
