Center Enamel: EPC Contractor for Palm Oil Wastewater Treatment Project in Vietnam

As a fast-growing palm oil producer in Southeast Asia, Vietnam has been expanding its oil palm cultivation and processing capacity across the Mekong Delta, Southeast region, and Central Highlands. The booming palm oil industry brings considerable economic benefits, yet it also raises strict requirements for environmental protection and waste management. A reliable Palm Oil Wastewater Treatment Project has become a necessary investment for every compliant palm oil mill in Vietnam.

Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) acts as a professional Palm Oil Wastewater Treatment Project EPC Contractor, providing full turnkey solutions integrating advanced anaerobic technologies, high-quality GFS tanks, and standardized EPC services to help Vietnamese palm oil enterprises realize harmless wastewater treatment and high-value biogas energy recovery.

 

 

Generation and Environmental Hazards of Palm Oil Mill Wastewater

Palm oil mill effluent (POME) is mainly generated from three key production procedures: fresh fruit bunch sterilization, oil pressing and clarification, and process equipment washing. This wastewater has extremely harsh characteristics that make it difficult to treat with conventional systems:

  • Ultra-high organic strength: COD typically ranges from 40,000 to 80,000 mg/L, which can cause serious oxygen depletion in rivers and soil.
  • High oil and grease content: Residual oil and fatty acids form impermeable layers that damage aquatic life and block natural water exchange.
  • High suspended solids: Fiber, pulp, and sediment lead to pipe blockage, equipment abrasion, and sediment accumulation.
  • Acidic and high-temperature properties: Raw POME is usually at pH 4–5 and 40–60°C, accelerating corrosion and reducing treatment stability.

Without proper treatment, POME will contaminate water sources, destroy mangrove and wetland ecosystems, and violate Vietnam’s industrial discharge regulations. For palm oil producers, building a legally compliant and efficient Palm Oil Wastewater Treatment Project is essential for long-term operation and market access.

 

 

Advanced Anaerobic Technologies for Vietnam Palm Oil Wastewater Treatment

Center Enamel provides a full set of high-efficiency anaerobic solutions customized for Vietnam’s palm oil mills, with USR Process as the core recommended technology, plus mature CSTR, UASB, and IC processes to match different plant scales and site conditions.

1. USR Process (Upflow Solid-state Reactor)

The USR Process is specially designed for POME with high suspended solids and oil content. It uses hydraulic upflow to maintain a high-concentration sludge bed without mechanical mixing, ensuring stable treatment and consistent biogas production.

  • Advantages: Strong shock load resistance, low energy consumption, easy operation, excellent tolerance to oil and fiber.
  • Application: Ideal for small-to-medium palm oil mills in Vietnam seeking stable, low-maintenance treatment.

2. CSTR Process (Completely Stirred Tank Reactor)

CSTR uses powerful mechanical agitation to fully mix sludge, wastewater, and solid residues, preventing crusting and sedimentation.

  • Advantages: Strong handling capacity for high-solid streams, stable performance, continuous biogas output.
  • Application: Suitable for large-scale mills and integrated zero-waste processing facilities.

3. UASB Process (Upflow Anaerobic Sludge Blanket)

A globally proven technology, UASB allows wastewater to flow upward through a dense granular sludge bed to achieve high organic removal efficiency.

  • Advantages: Mature design, reliable performance, widely applied in Southeast Asia.
  • Application: Suitable for mills with relatively low suspended solids and mainly liquid-phase treatment.

4. IC Process (Internal Circulation)

IC is a high-rate anaerobic reactor that uses biogas-driven internal circulation to enhance mixing and treatment efficiency.

  • Advantages: High volumetric loading, compact footprint, strong resistance to organic shock loads.
  • Application: Preferred for large modern palm oil industrial hubs.

By combining oil separation, pH adjustment, and residue removal as pretreatment, Center Enamel ensures the Palm Oil Wastewater Treatment Project runs stably under variable POME conditions.

Core Advantages of Center Enamel in Vietnam Palm Oil Wastewater Treatment

As a leading Palm Oil Wastewater Treatment Project EPC Contractor, Center Enamel offers comprehensive strengths tailored to the Vietnamese market:

  • Proprietary enamel formulas: Over 200 patented enamel recipes provide superior corrosion resistance to acidic, oily POME.
  • Asia’s largest GFS tank manufacturing base: Automated production ensures consistent quality, short delivery, and on-time supply to remote sites.
  • International standard compliance: Products meet ISO 28765, AWWA D103-09, OSHA, and NSF/ANSI 61; each plate passes 1500V spark testing.
  • Localized engineering design: Systems adapt to Vietnam’s tropical humidity, coastal salinity, heavy monsoon, and seismic conditions.
  • Full-life EPC service: One-stop solution from design, procurement, fabrication, installation to commissioning and after-sales support.

 

Key Equipment for Palm Oil Wastewater Treatment by Center Enamel

Center Enamel supplies highly durable equipment specially engineered for POME’s harsh environment:

1. Glass-Fused-to-Steel (GFS) Tanks

GFS tanks are the core of anaerobic treatment systems, formed by fusing glass and steel at over 820°C.

  • Corrosion resistance: Wide pH 1–14 tolerance, unaffected by organic acids, oil, and aggressive compounds.
  • Seismic and weather stability: Bolted structure offers better flexibility than concrete; resistant to strong UV and heavy rain.
  • Application: Anaerobic reactors, biogas digesters, and effluent storage tanks.

2. Fusion Bonded Epoxy (FBE) Coated Tanks

Used for equalization, intermediate storage, and treated water tanks with cost-effective anti-corrosion performance.

3. Biogas Storage and Utilization Equipment

  • Double Membrane Gas Holders: High air tightness, safe biogas storage and pressure control.
  • Biogas desulfurization and power generation units: Convert biogas into on-site electricity or thermal energy.

4. Tank Roof Systems

  • Aluminum Dome Roof: Windproof, rainproof, salt-spray resistant, ideal for Vietnam’s tropical coastal climate.
  • Enamel Roof, Air Membrane Roof, FRP Roof, and Sun Panel Roof for diversified application scenarios.
