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
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 aggregate into larger flocs that can be easily removed through sedimentation or filtration.
Q What is the Al2O3 content in your PAC powder, and why does it matter?
Our PAC powder contains ≥28.0% to 29.0% Al2O3. A higher Al2O3 content indicates greater purity and more effective flocculation performance, resulting in better water treatment outcomes and lower dosage requirements.
Q What is the difference between PAC-02, PAC-04, and PAC-06?
PAC-02 is designed for industrial water treatment (yellow powder, Al2O3 22.0–26.0%), while PAC-04 and PAC-06 are suitable for drinking water treatment. PAC-04 is white with Al2O3 ≥29.0%, and PAC-06 is light yellow with Al2O3 ≥28.0%. All three grades have a pH range of 3.5–5.0 in 1% water solution.
Q Can PAC powder be customized for specific water treatment requirements?
Yes. We offer customized PAC formulations based on your specific water quality, treatment goals, and operational conditions. Please contact us with your technical requirements and we will provide a tailored solution.
Q What are the available packaging options and shelf life for PAC powder?
PAC powder is available in 25kg/bag, 1000kg/bag, and bulk shipment of 25MT per 20-foot container (20FCL). The shelf life is 2 years when stored properly in a cool, dry, and well-ventilated environment away from moisture and direct sunlight.
Q In which industries is PAC powder most commonly applied?
PAC powder is widely used across multiple industries including municipal drinking water and urban water supply, industrial wastewater treatment, papermaking, pharmaceuticals, refined sugar and liquor production, cosmetic manufacturing, and daily chemical production.
