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 (FAQ)
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 clump together 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 higher water insolubles tolerance (≤0.5%). PAC-04 and PAC-06 are formulated for drinking water treatment with a higher Al2O3 content (29.0% and 28.0% respectively) and stricter water insolubles limit (≤0.1%), ensuring safer and cleaner treated water.
What are the recommended dosage and application methods for PAC powder?
PAC powder requires a smaller dosage compared to other conventional flocculants. It is typically dissolved in water before being added to the treatment system. The exact dosage depends on the water source quality, turbidity, and temperature. It is adaptable to a wide pH range of 3.5–5.0 (measured at 1% water solution), making it versatile for various water conditions.
Can PAC powder be used in drinking water treatment safely?
Yes. PAC-04 and PAC-06 grades are specifically designed for drinking water treatment. They meet strict quality standards with water insolubles of ≤0.1% and an Al2O3 content of 28.0%–29.0%. These grades comply with ISO standards and are suitable for municipal drinking water purification and urban water supply systems.
What is the shelf life and packaging options available for PAC powder?
PAC powder has a shelf life of 2 years when stored properly in a dry and cool environment. It is available in multiple packaging options: 25 kg/bag for smaller quantities, 1,000 kg/bag (jumbo bag) for bulk orders, and 25 MT per 20-foot container (20FCL) for large-scale industrial procurement.
Can PAC powder specifications be customized for specific industrial requirements?
Yes. PAC powder products can be customized based on specific customer requirements, including adjustments to Al2O3 content, basicity levels, and packaging formats.
