Center Enamel Provides Anaerobic Digester Tanks For United Kingdom Wastewater Treatment Project

Center Enamel Provides Anaerobic Digester Tanks For United Kingdom Wastewater Treatment Project

The United Kingdom is at the forefront of climate action, circular economy integration, and environmental protection. With growing demands for decarbonisation, increased population density, and ageing water infrastructure, the UK faces mounting pressure to modernise wastewater treatment systems. One solution gaining prominence is anaerobic digestion (AD), which enables energy recovery, greenhouse gas reduction, and enhanced sludge treatment.

Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel), a global leader in advanced storage tank solutions, proudly supports this transition. With over 30 years of engineering excellence and an extensive international project portfolio, Center Enamel offers world-class anaerobic digester tanks tailored for the UK’s complex regulatory and environmental landscape.

UK Wastewater and Sludge Management Needs Innovative Solutions

The UK generates over 1.4 billion tonnes of wastewater per year, processed by more than 9,000 treatment plants across England, Scotland, Wales, and Northern Ireland. Anaerobic digestion plays a crucial role in these systems by converting sludge and organic waste into biogas, which can be used to produce heat and electricity, or upgraded to biomethane for injection into the national gas grid.

Increasing pressure to reduce landfill and incineration reliance

Anaerobic digestion enables cost savings, resource recovery, and compliance with government mandates. Center Enamel's tanks deliver scalable, reliable, and durable infrastructure to meet these national objectives.

Why Center Enamel Anaerobic Digester Tanks Stand Out

Center Enamel specializes in the manufacture of Glass-Fused-to-Steel (GFS) anaerobic digester tanks. This advanced technology combines the strength of steel with the corrosion resistance of glass, creating a long-lasting, high-performance containment solution for aggressive environments like those in AD plants.

Our anaerobic digester tanks are widely used in:

Municipal wastewater treatment plants

Agricultural and food waste AD facilities

Industrial effluent treatment systems

Combined heat and power (CHP) operations

Green gas grid injection schemes

Core Advantages of Our GFS Anaerobic Digester Tanks

Superior Corrosion Resistance

Acid and alkali resistant (pH range 1–14)

Impervious to hydrogen sulphide, ammonia, and other aggressive gases/liquids

Proven Durability and Longevity

Over 30-year design life

Hardness of 6.0 on the Mohs scale

Tight Sealing for Biogas Retention

Center Enamel embraces sustainability in every aspect of manufacturing and project execution. From eco-friendly coatings to efficient logistics, we reduce the environmental footprint of our tanks. Our operations align with UN Sustainable Development Goals (SDGs) and ESG frameworks—values that matter to British stakeholders.

Supporting UK’s Net-Zero and Bioeconomy Goals

Anaerobic digestion contributes to:

Decarbonising wastewater treatment

Reducing landfill methane emissions

Boosting renewable energy production

Generating bio-fertilizers and closing nutrient loops

Center Enamel’s anaerobic digester tanks are more than infrastructure—they are essential tools for reaching Net Zero by 2050, fulfilling the UK government’s climate commitments and energy security agenda.
