China’s Leading Liquid Leachate Tanks Manufacturer

China’s Leading Liquid Leachate Tanks Manufacturer

China’s waste and wastewater sector increasingly relies on advanced tank technology to safely manage highly corrosive landfill leachate and industrial effluents. Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) has emerged as China’s leading liquid leachate tanks manufacturer, delivering engineered containment solutions that protect the environment while supporting efficient landfill and waste treatment operations in more than 100 countries.

Leader in Liquid Leachate Containment

Center Enamel specializes in Glass-Fused-to-Steel (GFS) and epoxy coated bolted steel tanks designed specifically for harsh liquids like landfill leachate, industrial leachate, and complex wastewater streams. With over 30 years of experience in modular tank systems, the company has built a reputation as the “Global China Epoxy Coated Steel Landfill Leachate Tanks Manufacturer,” supporting projects on six continents.

• Founded in 1989, Center Enamel has grown into a world-renowned manufacturer of GFS, epoxy coated, stainless steel, and carbon steel tanks for industrial and municipal applications.
• The company’s advanced production base of nearly 150,000 m² integrates enamel lines, epoxy coating lines, CNC processing, and automated quality control, ensuring consistent quality and fast delivery.
• All tanks are designed and manufactured in accordance with international standards such as ISO 9001, AWWA D103, NSF/ANSI 61, EN ISO 28765, and relevant seismic and wind load codes.

Why Leachate Requires Specialized Tanks

Landfill leachate is a complex and hazardous liquid formed when rainwater and waste interact, carrying dissolved organic matter, heavy metals, ammonia, chlorides, and various toxic compounds. Without secure storage and treatment, leachate can pollute soil, groundwater, and surface water, posing serious threats to ecosystems and public health.

• Leachate often shows high chemical aggression and acidity, demanding tanks with excellent corrosion resistance and impermeability.
• Long-term storage capacity is crucial, as landfills generate large volumes of leachate daily that must be temporarily stored before treatment.
• Environmental regulations worldwide require secure containment, leak prevention, and robust structural performance under seismic and wind loads.

Center Enamel’s leachate tanks are engineered specifically around these challenges, combining advanced coatings, robust bolted designs, and application-focused engineering.

Advanced GFS and Epoxy Tank Technologies

Center Enamel offers two core technologies for liquid leachate storage: Glass-Fused-to-Steel tanks and epoxy coated bolted steel tanks, both optimized for high corrosion resistance and long service life.

Glass-Fused-to-Steel (GFS) Leachate Tanks

GFS tanks are manufactured by firing special glass at 820–930°C onto pre-treated carbon steel plates, creating a strong chemical bond between glass and steel.

• The resulting coating is smooth, non-porous, and highly resistant to acidic and chemically aggressive leachate, enabling service lives measured in decades.
• GFS leachate tanks are available from 20 m³ up to 50,000 m³, offering scalability for small local landfills and large regional treatment facilities.
• All GFS leachate tanks comply with AWWA D103, with design options for water supply and drainage, seismic loads, wind resistance, lightning protection, and insulation.

Epoxy Coated Steel Leachate Tanks

Epoxy coated bolted tanks provide another high-performance option for liquid leachate storage and treatment processes.

• Center Enamel uses a high-performance epoxy resin powder applied to carefully prepared steel panels, followed by thermal fusion bonding to create a tough, impermeable barrier.
• This epoxy layer isolates the steel from the corrosive leachate, dramatically extending tank lifespan and maintaining structural integrity.
• Epoxy coated leachate tanks are ideal for applications requiring high chemical resistance, fast installation, and flexible design integration with treatment equipment.

Both technologies are offered as modular bolted tanks, allowing fast on-site assembly, simplified transportation, and easy future expansion.

Key Design Features for Leachate Storage

To ensure safety and reliability in demanding landfill environments, Center Enamel’s liquid leachate tanks integrate multiple design features that support structural stability, leak prevention, and environmental compliance.

• Bolted modular design: Panels are prefabricated and bolted together with special sealants and hardware, enabling fast installation and easier maintenance compared with welded tanks.
• High-capacity configurations: Tank sizes and heights are tailored to leachate generation volume, treatment plant layout, and available footprint.
• Special roofs and covers: Aluminum dome roofs, membrane roofs, and other roof systems prevent rainwater ingress and odor emissions while providing structural protection.
• Secondary containment options: Systems can be integrated with bunds and monitoring to meet stricter environmental regulations.
• Integration with treatment processes: Tanks can include nozzles, manways, process inlets/outlets, mixers, instrumentation, and pipeline connections suited to leachate treatment systems.

These engineering choices ensure that every tank is not merely a storage vessel but a core part of a safe, efficient leachate management system.

Advantages Over Conventional Solutions

Compared with traditional concrete, basic carbon steel, or low-spec plastic tanks, Center Enamel’s GFS and epoxy coated leachate tanks deliver clear advantages in durability, cost efficiency, and environmental performance.

• Outstanding corrosion resistance
  • GFS and epoxy coatings withstand the highly corrosive nature of leachate far better than uncoated or poorly protected steel.
  • This significantly extends service life and reduces the risk of leaks and costly structural failures.
• Long-term economic benefits
  • Lower maintenance requirements and extended lifespans reduce lifecycle costs compared with concrete or FRP alternatives.
  • Bolted designs decrease installation time and labor, supporting tight project schedules and minimizing downtime for existing facilities.
• Environmental safety and regulatory compliance
  • High-integrity coatings and leak-proof design help prevent groundwater and soil contamination.
  • Compliance with international standards supports permitting and environmental audits in multiple jurisdictions.

These advantages make Center Enamel a preferred partner for landfill operators, EPC contractors, and environmental engineering firms seeking reliable leachate storage solutions.

Applications in Landfill and Waste Management

Center Enamel’s liquid leachate tanks are designed for a broad range of landfill and waste sector scenarios where secure containment is critical.

• Municipal solid waste landfills
  • Storage of raw landfill leachate prior to biological or physico-chemical treatment.
  • Equalization tanks to balance flow and load variations between the landfill and treatment plant.
• Domestic waste incineration projects
  • Landfill leachate storage tanks for domestic waste incineration plants, integrating with leachate pre-treatment and reuse systems.
  • Tanks designed to handle high variability in composition and temperature typical of incineration-related leachate.
• Industrial waste and hazardous leachate
  • Storage of complex industrial leachates that contain aggressive chemicals and heavy metals.
  • Integration into industrial wastewater treatment systems as buffer, reaction, or equalization tanks.

By covering both municipal and industrial applications, Center Enamel supports comprehensive waste management strategies from landfill cells to centralized treatment facilities.
