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.
-
1It 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%.
-
2It 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.
-
3It is capable of adapting to a wide range of pH values, and it reduces the pH value and basicity after the processing.
-
4It requires a smaller dosage than that of other flocculants. It has wide adaptability to the waters at different temperatures and in different regions.
-
5It 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
Q 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 (flocculate) and settle out, resulting in cleaner, clearer water.
Q What is the difference between PAC-02, PAC-04, and PAC-06?
PAC-02 (yellow powder, Al2O3 22–26%) is designed for industrial water treatment. PAC-04 (white powder, Al2O3 ≥29.0%) and PAC-06 (light yellow powder, Al2O3 ≥28.0%) are both formulated for drinking water treatment, offering lower water insolubles (0.1%) and meeting stricter quality standards.
Q What are the recommended dosage and application methods for PAC powder?
PAC powder is typically dissolved in water before dosing. The required dosage is lower compared to other conventional flocculants, which helps reduce overall treatment costs. Exact dosage depends on raw water quality, turbidity, and temperature — customized recommendations are available upon request.
Q What industries and applications is PAC powder suitable for?
PAC powder is widely applied in drinking water purification, urban water supply, precision manufacturing water treatment, papermaking, pharmaceutical production, refined sugar and liquor processing, cosmetic additive manufacturing, and various daily chemical applications.
Q How should PAC powder be stored, and what is its shelf life?
PAC powder has a shelf life of 2 years when stored properly in a cool, dry, and well-ventilated area, away from moisture and direct sunlight. It is available in 25kg bags, 1000kg bulk bags, or 25MT per 20-foot container for large-volume orders.
Q Can PAC powder specifications be customized to meet specific requirements?
Yes. PAC powder can be customized based on your specific application requirements, including Al2O3 content, basicity range, and packaging format. Please contact us with your technical specifications and we will provide a tailored solution.
