What is Liquid PAC? What is the Al₂O₃ Percentage?
Liquid PAC (Poly Aluminium Chloride, CAS 1327-41-9) is a liquid coagulant with Al₂O₃ content ranging from 10% to 17%. It is easy to pump and dose, does not generate dust — a significant advantage over PAC powder in water plants and industrial wastewater treatment. Loc Thien provides liquid PAC that meets QCVN 01:2009/BYT for domestic water supply, accompanied by full documentation including CoA, CO, CQ, MSDS.

Dosage of Liquid PAC Based on Water Turbidity

Low turbidity water (below 50 NTU): 1–3 mg/L of 10% liquid PAC.
Medium turbidity water (50–200 NTU): 3–8 mg/L of 10–17% liquid PAC.
High turbidity water (above 200 NTU): 8–15 mg/L of 17% liquid PAC, combined with coagulant aid polymer.
Directly pump into the rapid mixing point. No additional dilution is required for liquid PAC.

Frequently Asked Questions About Liquid PAC

What is liquid PAC? What is the Al₂O₃ percentage?

Liquid PAC (Poly Aluminium Chloride, CAS 1327-41-9) is an aluminum-based coagulant solution with Al₂O₃ content ranging from 10% to 17%. The liquid form allows direct pumping and dosing, does not generate dust, and is suitable for automated systems in water plants and industrial wastewater treatment.

What is the difference between 10% and 17% liquid PAC? How is it used for turbid water?

10% liquid PAC is suitable for low to medium turbidity water (10–100 NTU), with a dosage of 1–5 mg/L. 17% liquid PAC is used for high turbidity water (100–500 NTU) or industrial wastewater, with a dosage of 5–15 mg/L. Higher Al₂O₃ concentration means less chemical is needed to achieve the same coagulation efficiency.

Liquid PAC vs PAC powder — advantages and disadvantages in water plants?

Advantages of liquid PAC: direct pumping, dust-free, easy automation, safe for workers. Disadvantages: lower concentration than PAC powder, requiring larger storage tanks. Advantages of PAC powder: high concentration (28-31%), saves storage space. Disadvantages: requires pre-mixing, generates dust, inhalation risk. For automated water plants, liquid PAC is the optimal choice.

What is the dosage of liquid PAC for water with 50–200 NTU turbidity?

For water with 50–200 NTU turbidity, the recommended dosage of liquid PAC is: 3–8 mg/L (10% liquid PAC) or 2–5 mg/L (17% liquid PAC). A jar test should be conducted to determine the optimal dosage for each water source. Loc Thien offers free jar test support for purchases of 200 kg/month or more.

Does liquid PAC meet QCVN 01:2009/BYT for water supply?

Yes. Loc Thien's liquid PAC meets QCVN 01:2009/BYT for domestic water supply applications. Each batch comes with CoA (Certificate of Analysis), CO (Certificate of Origin), CQ (Certificate of Quality), and MSDS (Material Safety Data Sheet). Customers can request documentation before placing orders.
