Leading Wastewater Treatment Contractors for Fermentation Industry in Vietnam

Vietnam has emerged as a global hub for fermentation-based manufacturing, from large-scale MSG (Monosodium Glutamate) plants to bio-ethanol and antibiotic production. However, fermentation wastewater is among the most challenging to treat due to ultra-high COD (Chemical Oxygen Demand), high sulfate concentrations, and high salinity. As of 2026, MONRE (Ministry of Natural Resources and Environment) mandates advanced resource recovery for high-load industrial effluents.
Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) is the leading global Wastewater Treatment Contractor providing specialized EPC solutions. We utilize high-rate anaerobic technology to convert the high organic load of fermentation waste into valuable biogas energy.
1. Specialized Treatment Process Flow
Fermentation wastewater requires a sophisticated, multi-stage anaerobic-aerobic sequence to handle extreme organic concentrations.
- Pre-Treatment (Acidification & Desulfurization): High-sulfate wastewater requires a dedicated pre-acidification stage to manage pH and H2S production, protecting downstream biological units.
- Secondary Treatment (The IC/EGSB Core): High-rate Internal Circulation (IC) or Expanded Granular Sludge Bed (EGSB) reactors are essential. These systems handle COD loads exceeding 20,000–30,000 mg/L, typical in ethanol and MSG production.
- Tertiary Treatment (Nitrogen Removal): Fermentation waste is often nitrogen-rich. We utilize A/O (Anoxic/Oxic) or SBR (Sequencing Batch Reactor) processes to ensure compliance with Vietnam’s total nitrogen (TN) limits.
- Advanced Polishing: Integration of Fenton oxidation or MBR (Membrane Bioreactors) ensures the removal of recalcitrant organics and color, reaching Class A discharge standards.
2. Core Technologies (2026 Standards)
Advanced Anaerobic Digestion & Biogas Valorization
In Vietnam’s push for "Green Manufacturing," the energy potential of fermentation waste is a critical asset.
- IC Reactors: Our IC technology provides a compact footprint with high-intensity mixing, essential for the high-concentration fermentation streams found in industrial zones like Long Thanh or Hai Phong.
- Biogas Recovery: Captured methane is purified and used in factory boilers or power generators, significantly reducing the carbon intensity of the production cycle.
Containment Excellence: Glass-Fused-to-Steel (GFS) Tanks
Fermentation wastewater is highly corrosive, often containing organic acids and chlorides that destroy concrete.
- Corrosion Resistance: Our GFS tanks feature a titanium-rich glass coating with a pH resistance range of 1–14, ensuring a service life of 30+ years.
- Rapid Deployment: Bolted GFS tanks can be installed 50% faster than concrete, which is critical for Vietnam’s fast-track industrial expansion projects.
Nitrogen and Phosphorus Recovery
A 2026 innovation in our EPC services involves stripping ammonia and recovering phosphorus as Struvite, turning a treatment challenge into a high-value fertilizer byproduct for Vietnam’s agricultural sector.

4. Critical Challenges & Solutions for Vietnam
- High Salinity and Sulfates: Our IC reactors are engineered with specialized granular sludge that remains stable even in the high-conductivity environments typical of MSG and ethanol effluent.
- Land Scarcity in Industrial Parks: As land prices in Binh Duong and Bac Ninh rise, our vertical treatment architecture allows for massive capacity increases within small physical footprints.
- ESG & Export Compliance: For Vietnamese manufacturers exporting to the EU and North America, our systems provide the real-time data tracking required for Carbon Border Adjustment Mechanism (CBAM) reporting.
