Dosage of Liquid PAC (Polyaluminium Chloride) Based on Water Turbidity

Low turbidity water (below 50 NTU): 1–3 mg/L liquid PAC (Polyaluminium Chloride) 10%.
Moderately turbid water (50–200 NTU): 3–8 mg/L liquid PAC (Polyaluminium Chloride) 10–17%.
High turbidity water (above 200 NTU): 8–15 mg/L liquid PAC (Polyaluminium Chloride) 17%, combined with a coagulation-enhancing polymer.
Directly dose into the rapid mixing point. No further dilution with liquid PAC (Polyaluminium Chloride) is required.

Frequently Asked Questions About Liquid PAC (Polyaluminium Chloride)

What is liquid PAC (Polyaluminium Chloride)? What is the Al₂O₃ percentage?

Liquid PAC (Polyaluminium Chloride)

What is the difference between liquid PAC (Polyaluminium Chloride) 10% and 17%? How are they used for turbid water?

Liquid PAC (Polyaluminium Chloride) 10% is suitable for water with low to moderate turbidity (10–100 NTU), at a dosage of 1–5 mg/L. Liquid PAC (Polyaluminium Chloride) 17% is used for highly turbid water (100–500 NTU) or industrial wastewater, at a dosage of 5–15 mg/L. A higher Al₂O₃ concentration means less chemical is needed to achieve the same coagulation effect.

Liquid PAC (Polyaluminium Chloride) vs. Powdered PAC (Polyaluminium Chloride) — Advantages and Disadvantages in Water Treatment Plants?

Liquid PAC advantages: direct dosing, dust-free, easy to automate, and safe for workers. Disadvantages: lower concentration than powdered PAC, so larger storage tanks are required. Powdered PAC advantages: high concentration (28–31%), saves storage space. Disadvantages: Must be pre-mixed, generates dust, and poses an inhalation risk. For automated water treatment plants, liquid PAC (Polyaluminium Chloride) is the optimal choice.

What is the recommended dosage of liquid PAC (Polyaluminium Chloride) for turbid water at 50–200 NTU?

For turbid water at 50–200 NTU, the recommended dosage of liquid PAC (Polyaluminium Chloride) is: 3–8 mg/L (liquid PAC (Polyaluminium Chloride) 10%) or 2–5 mg/L (liquid PAC (Polyaluminium Chloride) 17%). A Jar Test should be conducted to determine the optimal dosage for each water source. Loc Thien offers free Jar Tests for purchases of 200 kg or more per month.

Does Loc Thien’s liquid PAC (Polyaluminium Chloride) comply with the QCVN 01:2009/BYT standard for potable water?

Yes. Loc Thien’s liquid PAC (Polyaluminium Chloride) meets the QCVN 01:2009/BYT standard for potable water applications.
