Center Enamel: Professional EPC Contractor for Vietnam Chicken Farm Biogas Projects

Vietnam has one of the most prosperous chicken farming industries in Southeast Asia. Poultry breeding is widely distributed across the Mekong Delta, Red River Delta, Central Highlands and major agricultural provinces such as Dong Nai, Binh Duong and Hanoi. The country owns a large number of large-scale intensive chicken farms, medium-sized breeding bases and countless scattered rural poultry households. With the continuous expansion of market demand and breeding scale, Vietnam generates massive volumes of chicken manure, urine and breeding wastewater every single day.

Most chicken farms in Vietnam lack standardized waste disposal infrastructure. Untreated chicken manure is randomly piled up or directly discharged into rivers, canals and farmland. This causes severe odor pollution, river eutrophication, groundwater contamination and frequent pathogen breeding. It also releases large amounts of greenhouse gases and damages local ecological balance. Even so, chicken manure is rich in organic carbon, nitrogen, cellulose and degradable nutrients, making it ideal raw materials for biogas production.

Under Vietnam’s renewable energy strategy and environmental protection policies, adopting professional Anaerobic Solutions, mature CSTR Process and high-performance GFS Tanks has become an inevitable choice for solving poultry pollution and realizing clean energy utilization. As a global leading EPC contractor, Center Enamel has rich Southeast Asian project experience, providing customized anaerobic processes, complete tank equipment and one-stop turnkey biogas solutions tailored to Vietnam’s tropical monsoon climate and chicken manure characteristics.

Biogas Production Process from Chicken Manure

Chicken manure produces biogas through natural oxygen-free anaerobic digestion. The complete biological production process includes four core stages:

  • Hydrolysis: Complex organic substances such as protein and cellulose in chicken manure are decomposed into simple soluble small molecules.
  • Acidification: Acidogenic bacteria convert small molecular organics into volatile fatty acids, hydrogen and carbon dioxide.
  • Acetogenesis: Intermediate substances are further transformed into acetic acid, the direct precursor of methane production.
  • Methanogenesis: Methanogenic archaea consume acetic acid to produce methane and carbon dioxide, forming methane-rich biogas.

After collection, desulfurization and purification, biogas can be used for farm power generation, boiler heating and rural daily cooking. The digested residues and slurry are processed into high-quality organic fertilizer, realizing a closed-loop circular economy. Vietnam’s year-round high temperature and humid tropical climate maintain stable microbial activity, ensuring continuous and efficient biogas output throughout the year.

Advantages of Chicken Farm Biogas Project for Vietnam Energy Development

Developing chicken farm biogas projects brings remarkable economic, environmental and social benefits to Vietnam’s energy and rural development.

First, it effectively controls chicken manure odor and water pollution, helping poultry farms meet national environmental discharge standards and protect river and rural ecological resources.

Second, biogas eases Vietnam’s rural power shortage and unstable grid supply, reducing reliance on imported fossil fuels and greatly improving rural energy self-sufficiency.

Third, biogas replaces firewood and biomass burning, reducing deforestation pressure and protecting Vietnam’s tropical forests and ecological environment.

Fourth, biogas digestate reduces chemical fertilizer dependence, improves soil fertility and increases crop yields, promoting circular agricultural development in rural areas.

In addition, biogas project construction and operation drive local employment, supporting Vietnam’s carbon reduction goals and sustainable green energy roadmap.

Four Main Anaerobic Technologies

Center Enamel provides four mature anaerobic technologies perfectly customized for Vietnam’s tropical climate, chicken manure characteristics and different farm scales.

CSTR (Completely Stirred Tank Reactor)

As the core recommended CSTR Process for Vietnam chicken farms, it is specially designed for high-solid chicken manure. High-torque mechanical stirring ensures full mixing of sludge and raw materials, preventing crusting and sedimentation. It runs stably with strong anti-impact load capacity and maintains continuous biogas output, ideal for large intensive chicken farms and industrial poultry parks.

UASB (Upflow Anaerobic Sludge Blanket)

Classic cost-effective anaerobic technology for chicken farm wastewater. Wastewater flows upward through dense granular sludge to efficiently degrade organic pollutants. It features simple structure, low operation cost and easy maintenance, suitable for medium-sized chicken farms across Vietnam.

USR (Upflow Solids Reactor)

Optimized for high-suspended-solid chicken manure. It has a simple layout, low investment cost and strong raw material adaptability, perfectly matching scattered small rural chicken households.

IC (Internal Circulation)

Advanced high-rate anaerobic technology driven by internal biogas circulation. Its volumetric loading capacity is 3–5 times higher than traditional reactors. It saves land occupation and delivers excellent COD removal efficiency, the best choice for super-large integrated chicken farm biogas projects.

Core Equipment for Vietnam Chicken Farm Biogas Project

Center Enamel supplies reliable, durable, and high-performance equipment for Vietnam chicken farm Biogas Project.

Glass-Fused-to-Steel (GFS) Tanks

GFS tanks are the core of anaerobic digestion systems. Fused at over 820°C, they offer:

  • Full pH resistance (1–14) to withstand corrosive chicken manure and digestate
  • Strong weather resistance, UV stability, and long service life
  • Bolted assembly for fast installation and flexible expansion
  • Service life exceeding 30 years with minimal maintenance

Double Membrane Gas Holders

These provide safe biogas storage with automatic pressure control, stable gas supply, and explosion protection for power generation systems.

Fusion Bonded Epoxy (FBE) Tanks

Used for equalization, pre-treatment, and water storage, FBE tanks offer cost-effective corrosion resistance for auxiliary processes.

Tank Roof Systems

  • Air Membrane Roof: Flexible, lightweight, and gas-tight with automatic pressure adjustment.
  • Enamel Roof: Highly corrosion-resistant GFS roof for harsh chemical environments.
  • Sun Panel Roof: Light-transmitting, weather-resistant, and durable.
  • Aluminum Flat Roof: Cost-effective, salt-spray resistant, and easy to install.
  • FRP Roof: Lightweight, high-strength, and chemically stable.
  • Aluminum Dome Roof: Arched, wind-resistant, rainproof, ideal for Vietnam’s tropical monsoon climate.

Agitation, Feeding, and Discharging Systems

Supporting equipment ensures stable material flow, efficient reaction, and reliable operation of the entire biogas system.
