Technical Comparison: PAFC 20% vs. PAFC 28%
| Feature | PAFC 20% (Industrial Grade) | PAFC 28% (Premium Grade) |
| Active Content | Al2O3 20% min | Al2O3 28% min |
| Appearance | Dark Brown Granules / Powder | Tan or Brownish-Yellow Granules |
| Solubility | General: Dissolves slightly slower, with a small amount of residue. | Excellent solubility: Dissolves instantly in water, with very low levels of insoluble matter. |
| Core Applications | Steel mills, paper mills, printing & dyeing, and heavy chemical wastewater. | Municipal water pre-treatment, food processing, and high-standard industrial effluent. |
| Cost Performance | Maximum Economy: Best for large-scale treatment on a budget. | Optimal Efficiency: Lower dosage required; reduces equipment corrosion. |
What is Poly Aluminium Ferric Chloride Used for?
- Water Treatment: Enhances coagulation to remove particles, turbidity, and organic matter in drinking/process water.
- Wastewater Treatment: Effectively treats municipal sewage, industrial effluents, and stormwater by removing solids, organics, and heavy metals.
- Industrial Applications: Used for coagulation/flocculation in industries like pulp & paper, textiles, mining, and oil & gas for wastewater treatment.
- Clarification and Settling: Promotes particle agglomeration and settling for clearer water/wastewater.
- Color Removal: Effectively removes dyes and color compounds, especially in textile/printing wastewater.
- Treatment of Challenging Water Sources: Suitable for difficult sources like high-turbidity or high-organic surface water.
FAQ of Poly Aluminium Ferric Chloride
It depends on your water quality and goals:
20% Purity: Ideal for heavy industrial wastewater (like paper or textile mills) where decoloring and cost-per-ton are the priorities.
28% Purity: Best for municipal water or precision manufacturing where you need high effluent clarity and want to minimize residual sludge volume.
This is one of its strongest selling points. Traditional aluminium coagulants react slowly in cold water, but the iron component in PAFC maintains high reactivity in low-temperature and low-turbidity conditions. It ensures stable water treatment performance year-round.
Yes, in most cases, PAFC can replace PAC 1:1 or even at a lower dosage. However, we recommend a Jar Test to determine the optimal ratio for your specific water chemistry.
Solid products are mainly sold in woven bags, typically 25 kg/bag, with an inner plastic bag.
Avoid storing in moisture, but excessive moisture will not affect its effectiveness; it will only increase its tendency to dissolve.
