PAC Chemical Supplier Vietnam: The Complete Industrial Buyer’s Guide 2026
If your facility depends on reliable water treatment — whether you run a municipal plant, a textile factory, or an aquaculture operation — securing a trusted PAC chemical supplier in Vietnam is one of the most critical procurement decisions you will make. Poly aluminium chloride (PAC) is the backbone of coagulation and flocculation processes, and supply disruptions can halt entire production lines or trigger compliance failures.
Loc Thien Chemical has supplied poly aluminium chloride across Vietnam for over a decade, serving industrial buyers in Ho Chi Minh City, Binh Duong, Dong Nai, and beyond. This guide covers everything a procurement manager or EHS engineer needs to know: what PAC is, how it compares to alum, which grade suits your application, and how to get competitive pricing with full documentation.
What Is PAC (Poly Aluminium Chloride)?
Poly aluminium chloride — commonly abbreviated as PAC — is an inorganic coagulant used to remove suspended solids, turbidity, colour, and certain heavy metals from water. Its chemical formula is [Al₂(OH)ₙCl₆₋ₙ]ₘ, where the degree of basicity (typically 50–80%) determines its coagulation efficiency.
Key properties at a glance:
| Parameter | Typical Range |
| Active Al₂O₃ content | 10% (liquid) – 31% (powder) |
| Basicity | 50–80% |
| pH (1% solution) | 3.5–5.0 |
| Colour | Pale yellow to amber (liquid); white to off-white (powder) |
| Solubility | Fully soluble in water at operating doses |
PAC works by releasing pre-hydrolysed aluminium species that bind colloidal particles, neutralise their surface charge, and aggregate them into settleable floc. Compared to traditional coagulants, PAC operates effectively across a wider pH range (5–9) and at lower dosages, which translates directly to lower sludge volumes and reduced chemical costs.
PAC vs Alum: Why Industrial Buyers in Vietnam Choose PAC
Aluminium sulphate (alum) has long been the default coagulant in Vietnam. However, as environmental regulations tighten and operational costs are scrutinised more closely, PAC water treatment is increasingly the professional choice for industrial applications. Here is why:
| Criterion | PAC (Poly Aluminium Chloride) | Alum (Aluminium Sulphate) |
| Effective pH range | 5.0 – 9.0 | 6.0 – 8.0 (narrower) |
| Dosage required | Lower (typically 30–50% less) | Higher |
| Sludge volume produced | Significantly less | More |
| Low-temperature performance | Effective (>5 °C) | Degrades significantly below 10 °C |
| Residual aluminium | Lower | Higher |
| Sulphate addition to water | None | High — may affect taste and corrosion |
| Cost per treated m³ | Lower total cost when factoring dosage | Lower unit price, higher dose cost |
| QCVN compliance ease | Easier to maintain effluent targets | Requires more precise control |
Practical verdict for Vietnamese industrial buyers: If your system handles variable influent quality, experiences seasonal temperature drops, or must meet QCVN 40:2021 effluent standards, PAC delivers more consistent results at a lower operational cost than alum.

Industries We Serve in Vietnam
Loc Thien Chemical supplies PAC to a broad cross-section of Vietnamese industry. Our sales and logistics teams understand the specific requirements — documentation, lead times, MOQ — of each sector.
Water Treatment Plants (Cấp nước — Thoát nước)
Municipal and industrial water treatment facilities represent our largest customer segment. PAC is used in clarification and filtration stages to meet QCVN 01-1:2018 (drinking water) and QCVN 40:2021 (industrial discharge) standards. We supply both liquid PAC for direct dosing and 31% powder for high-capacity systems.
Textile & Dyeing Factories
Textile wastewater carries heavy colour loads and suspended solids that demand effective coagulation. PAC — particularly the India 25% grade — is widely used in colour removal prior to biological treatment. We have supplied multiple dyeing factories in Binh Duong and Dong Nai with consistent monthly volumes.
Aquaculture & Shrimp Farming
Pond water management in shrimp and fish farming requires rapid turbidity reduction without introducing harmful residuals. PAC liquid 10% is food-production-compatible and can be dosed directly without complex equipment, making it the preferred choice for aquaculture operations in the Mekong Delta region.
Food & Beverage Processing
Wastewater from food processing — including slaughterhouses, seafood plants, and vegetable processing — contains high organic loads. PAC is used as a primary coagulant ahead of DAF (Dissolved Air Flotation) or settling systems. Applicable grades: PAC Liquid 10% and PAC India 25%.
Other sectors served: Paper & pulp, construction site runoff management, industrial laundry, mining water treatment.
