Introduction
Vietnam’s rapid industrialization — driven by FDI manufacturing relocation from China, a growing textile export sector, and extensive seafood processing — has created surging demand for industrial water treatment chemicals. With over 400 industrial parks nationwide and increasingly strict environmental enforcement under the 2020 Environmental Protection Law (Law No. 72/2020/QH14), Vietnamese factories need reliable, cost-effective treatment solutions. HydroChemix supplies high-quality PAC and PAM with fast ASEAN shipping to all major Vietnamese ports.
Vietnam Industrial Effluent Standards
QCVN 40:2011/BTNMT (National Technical Regulation on Industrial Wastewater):
| Parameter | Column A (discharge to water supply source) | Column B (discharge to non-supply waterbody) |
|---|---|---|
| pH | 6.0-9.0 | 5.5-9.0 |
| BOD (mg/L) | 30 | 50 |
| COD (mg/L) | 75 | 150 |
| TSS (mg/L) | 50 | 100 |
| Color (Pt-Co) | 50 | 150 |
| Total Nitrogen | 30 | 60 |
Note: Column A limits are among the strictest in ASEAN. Factories discharging to rivers used for drinking water supply face very tight COD and color limits, requiring optimized chemical treatment.
Key Industries and Treatment Solutions
1. Textile and Garment
Vietnam is the world’s 3rd largest textile exporter. Major textile hubs: Binh Duong, Dong Nai, Ho Chi Minh City, Hung Yen, Nam Dinh. Textile ETPs face challenges with reactive dye removal and meeting Column A color limits (50 Pt-Co). Our PAC 30% (high basicity 70-85%) combined with anionic PAM achieves 85-95% color removal. For mills discharging to water supply sources (Column A), a PAC + activated carbon polishing stage ensures compliance.
2. Seafood Processing (Shrimp, Pangasius, Tuna)
Vietnam is the world’s largest exporter of pangasius (basa fish) and among the top shrimp exporters. Seafood processing generates high-BOD, high-nitrogen wastewater from protein and cleaning chemicals. DAF with PAC (200-400 mg/L) + anionic PAM (2-5 mg/L) removes 70-90% TSS and 40-60% COD before biological treatment. Our PAC’s wide pH range handles the variable pH from seafood processing (acidic from protein decomposition to alkaline from cleaning chemicals).
3. Industrial Park Centralized WWTPs
Vietnam’s 400+ industrial parks operate centralized wastewater treatment plants receiving effluent from dozens of factories. These plants face highly variable influent quality and must maintain stable treatment 24/7. PAC is preferred over alum for centralized plants due to wider pH tolerance, faster floc formation, and reduced sludge volume — critical when handling 5,000-50,000 m3/day. Our consistent batch-to-batch quality is critical for plants where chemical dose rates are set and cannot be adjusted hourly.
4. Electronics and Metal Finishing
Vietnam’s growing electronics manufacturing (Samsung, LG, Foxconn suppliers in Bac Ninh, Thai Nguyen, Hai Phong) generates metal-containing wastewater requiring precipitation and flocculation. PAC (200-600 mg/L) provides effective heavy metal co-precipitation with pH adjustment, combined with PAM for solid-liquid separation.
Shipping and Logistics to Vietnam
- Main ports: Cat Lai/HCMC (south), Hai Phong (north), Da Nang (central)
- Transit time: 3-5 days to Hai Phong (nearest Chinese port route), 5-8 days to HCMC
- Advantage: Vietnam shares a land border with China — northern Vietnam clients (Hai Phong, Hanoi, Bac Ninh) can receive goods via cross-border trucking for even faster delivery (2-3 days) and lower freight cost than sea freight
- ASEAN FTA: Form E certificate for reduced import duty
- Documentation: COA, MSDS, commercial invoice, packing list, bill of lading (or road waybill for cross-border)
Why Vietnamese Companies Choose HydroChemix
- Fastest delivery in the market — 3-5 days sea freight or 2-3 days cross-border trucking
- Land border option unique to Vietnam — no other major PAC exporter can match this speed for northern clients
- Consistent quality with full COA documentation
- Free samples for jar testing at your ETP or centralized WWTP
- ASEAN FTA preferential rates reduce import costs
- Flexible packaging and order sizes
