Advantages
The following are the key benefits of this advanced flocculant in water treatment, making it a preferred choice for various industrial and municipal applications.
- 1 It provides a significantly better purifying effect than other organic flocculants in low-temperature, low-turbidity, and heavy organic-polluted raw water, with a cost reduction of 20%–80%.
- 2 It promotes significantly faster formation of flocculants, especially at low temperatures, with big sizes and rapid precipitation, extending the service life of cellular filters in sedimentation basins.
- 3 It is capable of adapting to a wide range of pH values, and it reduces the pH value and basicity after the processing.
- 4 It requires a smaller dosage than that of other flocculants. It has wide adaptability to the waters at different temperatures and in different regions.
- 5 It has higher alkalinity, lower corrosion, is easier for operation, and supports long-term use without causing clogging.
Application Field
It is widely used for purifying drinking water, urban water supply and precision manufacturing water, especially in the papermaking industry, medicine, refined sugar liquor, cosmetic additives and daily chemicals.
Frequently Asked Questions
What is Poly Aluminium Chloride (PAC) and how does it work?
Poly Aluminium Chloride (PAC) is an inorganic polymer flocculant with the molecular formula [AL2(OH)LnCL6-n]m. It works by neutralizing the negative charges on suspended particles in water, causing them to aggregate into larger flocs that can be easily removed through sedimentation or filtration.
What is the difference between PAC-02, PAC-04, and PAC-06?
PAC-02 is a yellow powder designed for industrial water treatment, with an Al2O3 content of 22.0–26.0% and water insolubles up to 0.5%. PAC-04 and PAC-06 are intended for drinking water treatment, offering higher Al2O3 purity (29.0% and 28.0% respectively) and stricter water insolubles of ≤0.1%, ensuring safer and cleaner output.
What are the recommended dosage and usage instructions for PAC powder?
PAC powder requires a smaller dosage compared to other flocculants. It should be dissolved in water (typically as a 1% solution with a pH of 3.5–5.0) before being added to the water to be treated. The exact dosage depends on the turbidity, temperature, and organic load of the source water. It is advisable to conduct jar tests to determine the optimal dosage for your specific application.
Is PAC powder safe for use in drinking water treatment?
Yes. PAC-04 and PAC-06 grades are specifically formulated for drinking water treatment. They meet stringent quality standards with water insolubles of ≤0.1% and Al2O3 content of ≥28.0–29.0%. The product complies with ISO standards for poly aluminium chloride used in potable water purification.
What are the storage conditions and shelf life of PAC powder?
PAC powder has a shelf life of 2 years when stored properly. It should be kept in a cool, dry, and well-ventilated area, away from moisture and direct sunlight. The product is available in 25 kg bags, 1,000 kg bulk bags, and 25 MT per 20-foot container for large-scale orders.
Can PAC be customized to meet specific industrial requirements?
Yes. The product specifications — including Al2O3 content, basicity, appearance, and packaging — can be customized based on your special requirements.
