Differentiating PAC Viet Tri, PAC China (Tenor) and PAC India
The PAC 31% market in Vietnam mainly comes from 3 sources: PAC Viet Tri domestically produced, PAC Tenor imported from China, and PAC India. Below is a comparison table based on actual COA data from batches Loc Thien is currently supplying. The choice of source depends on budget, quality requirements and specific treatment conditions of each plant.
| Criterion | PAC Viet Tri 31% | PAC Tenor (China) | PAC India |
|---|---|---|---|
| Origin | Vietnam | China | India |
| Al₂O₃ | 28–31% | 28–30% | 28–30% |
| Basicity | 40–60% | 40–70% | 40–50% |
| pH (1% solution) | 3.5–4.5 | 3.5–4.5 | 3.5–5.0 |
| Color | Off-white | Pale yellow | White |
| Price | Medium | Lowest | Highest |
| Quality consistency | High | Medium | High |
| Stock at Loc Thien | Continuous | Continuous | Made-to-order |
| Delivery time | 24–48 hours to Southern IPs | 24–48 hours to Southern IPs | Advance order |
PAC Viet Tri is the most balanced choice with stable quality, reasonable price and always available at Loc Thien’s warehouses. PAC Tenor China suits plants optimizing costs. PAC India is for organizations requiring clear origin with the highest quality. Loc Thien supplies all 3 sources, so customers can proactively choose based on their needs.
PAC 31% Applications in Water Treatment
PAC 31% powder is used in drinking water, wastewater, swimming pool and aquaculture treatment. For drinking water treatment, PAC 31% removes turbidity and organic matter at 10–30 mg/L, reducing sludge compared to alum. In industrial wastewater (textile dyeing, paper, seafood processing, food), PAC 31% achieves high coagulation efficiency at 20–60 mg/L, reducing COD by 65–80%. For swimming pool water, PAC 31% is used periodically at 5–10 mg/L combined with Javen for disinfection. In aquaculture ponds, dosage of 2–5 kg/1,000 m³ helps settle silt and heavy metals. Compared to PAC 17% liquid form, PAC 31% powder has double the content, saving transportation and storage costs. Combining with FeCl3 in wastewater treatment improves coagulation efficiency at low pH.
PAC 31% Dosage and Jar-test Procedure
PAC 31% dosage depends on turbidity, pH and source water properties. The table below provides reference dosages for common applications. Loc Thien recommends performing a jar-test before full-scale dosing to optimize performance and cost. Standard jar-test procedure: prepare PAC 31% as a 5–10% solution, add to 6 water beakers with increasing doses, rapid mix at 200 rpm for 2 minutes, slow mix at 40 rpm for 15 minutes, settle for 20 minutes and measure residual turbidity. The optimal dose is the one giving the lowest turbidity with maximum floc formation.
| Application | Reference dosage (mg/L) | Optimal pH | Notes |
|---|---|---|---|
| Drinking water supply | 10–30 | 6.5–8.5 | Reduce turbidity < 1 NTU |
| Textile dyeing wastewater | 30–60 | 6.0–8.0 | Reduce COD 65–75% |
| Seafood processing wastewater | 25–50 | 6.0–8.5 | Reduce COD, TSS |
| Swimming pool water | 5–10 | 7.0–7.8 | Weekly periodic treatment |
| Aquaculture ponds | 2–5 kg/1,000 m³ | 6.5–8.5 | Periodic treatment |
| Industrial park wastewater | 20–60 | 6.0–9.0 | Perform jar-test first |
Combining PAC 31% with PAC 10% liquid and NaOH helps flexibly adjust pH in continuous treatment systems. For wastewater sources with low pH, raise pH to 6.5–7.5 before dosing PAC using NaOH or lime.
Legal Documentation per Batch
Each batch comes with full legal documentation: real batch-specific COA (Certificate of Analysis), MSDS (Material Safety Data Sheet) and framework contract. Loc Thien’s quality control process consists of 3 steps: incoming inspection at warehouse by Phan Cam Thuy, periodic in-storage inspection, and pre-dispatch inspection approved by Vo Thi Nhu Hoa. CAS 1327-41-9 of PAC 31% is classified by the Ministry of Industry and Trade as a general industrial chemical, not on the list of precursors or restricted chemicals, facilitating purchase, sale and transport procedures.

Frequently Asked Questions about PAC 31%
Does PAC 31% dissolve completely in water?
Yes, PAC 31% powder dissolves completely in water, forming a clear solution. To speed up dissolution, dilute at a ratio of 5–10% (5–10 kg powder per 100 L water), stir for 5–10 minutes before dosing into the system.
How to distinguish PAC 31% powder from liquid PAC?
PAC 31% powder has 2–3 times higher Al₂O₃ content than liquid PAC (PAC 10% liquid has only 10% Al₂O₃). Powder PAC saves on transportation and storage costs but requires preparation time. Liquid PAC is more convenient for direct dosing systems.
Should I use PAC 31% or alum?
PAC 31% is superior to alum in 3 aspects: produces larger flocs, works well at low temperatures, and reduces sludge by 40–50%. Meanwhile, alum has a lower purchase price but higher sludge treatment costs.
Can PAC 31% be used together with FeCl3?
PAC 31% and FeCl3 can be used alternately or in combination depending on wastewater characteristics. FeCl3 (What is FeCl3?) is effective at low pH (4.0–6.0), while PAC 31% works well at neutral to alkaline pH (6.0–9.0). The two chemicals complement each other in systems with fluctuating pH.
Does PAC 31% require a coagulant aid?
For high-turbidity source water or fast-settling systems, combining PAC 31% with coagulant polymer (anionic or non-ionic) helps form larger flocs, faster settling, and reduces PAC consumption by 10–20%.
How to receive the real COA for the batch?
COA is sent with each dispatched batch. Customers can request COA before delivery via hotline. Each COA clearly states the production date, analysis results and approver.
What is the delivery time for PAC 31%?
Delivery to industrial parks in Ho Chi Minh City, Dong Nai, Binh Duong. Central and Northern regions: 24–48 hours. Call hotline 0979 891 929 to confirm specific delivery schedule per warehouse.
What is the shelf life of PAC 31%?
Shelf life is 24 months from production date, stored in a dry place away from direct sunlight. The product may absorb slight moisture but remains effective if still within shelf life and not hardened into lumps.
