How Polymeric Aluminum Ferric Chloride Works
We engineer Polymeric Aluminum Ferric Chloride (PAFC) to purify water through four simultaneous chemical processes. By combining pre-polymerized aluminum and iron, our PAFC coagulant targets suspended solids and dissolved impurities far faster than single-salt coagulants.
Core Flocculation Mechanisms
- Charge Neutralization: Negatively charged suspended particles in raw water naturally repel each other. The strong positive charges from aluminum and iron ions quickly neutralize these surface charges, allowing particles to collide and aggregate.
- Adsorption Bridging: Long polymer chains act as molecular bridges, grabbing onto multiple particles at once to build large, firmly bound flocs.
- Sweep Flocculation: As the coagulant precipitates, it forms heavy hydroxide nets that sweep fine impurities, organic matter, and color out of the water column.
The Aluminum and Iron Synergy
Our poly aluminum ferric chloride combines the distinct advantages of both metals into a single inorganic polymer structure:
| Component | Primary Function | Water Treatment Benefit |
|---|---|---|
| Aluminum (Al) | High charge density | Rapid charge neutralization and crystal-clear water |
| Iron (Fe) | High molecular weight & density | Heavier flocs, faster settling rates, and cold-water performance |
Why the Polymeric Structure Improves Settling and Turbidity Removal
Standard monomeric coagulants require extra time and energy to form polymers inside the raw water. Because our inorganic polymer flocculant is pre-polymerized during manufacturing, it works immediately upon dosing.
This pre-formed polymeric structure creates denser, larger, and tougher flocs that resist breaking under hydraulic shear. The added weight from iron ensures rapid sedimentation, dropping turbidity levels fast—even in challenging conditions like cold, low-turbidity raw water.
Performance Advantages of PAFC Over Other Coagulants
We engineered Polymeric Aluminum Ferric Chloride (PAFC) to overcome the performance limits of traditional single-metal coagulants. By combining aluminum and iron into a single inorganic polymer flocculant, PAFC provides faster settling, lower chemical consumption, and superior stability for demanding industrial and municipal water treatment.

Polymeric Aluminum Ferric Chloride Dosage and Application Guide
To get peak performance from Polymeric Aluminum Ferric Chloride (PAFC), correct dosing and proper solution preparation are essential. Because water characteristics vary significantly across different industrial sites, we always recommend tailoring feed rates to your specific plant conditions.
Run a Jar Test First
Before starting full-scale dosing, we strongly advise running a laboratory jar test. Factors like turbidity, water temperature, pH, and organic load directly dictate the optimal amount of PAFC coagulant required.
- Low-Turbidity Water: Typically requires 5–15 mg/L.
- Medium-to-High Turbidity Water: Ranges between 15–50 mg/L.
- Industrial Wastewater / High COD: Requires 50–200+ mg/L depending on heavy metal concentration and total suspended solids.
Dissolving and Dilution Guidance
We supply both solid powder and liquid Poly Aluminum Ferric Chloride. Follow these standard dilution ratios to prepare an effective working solution:
| PAFC Product Form | Preparation / Dilution Standard | Feeding Instructions |
|---|---|---|
| Solid PAFC Powder | Dissolve with clean water into a 5% – 10% solution. | Stir for 10–15 minutes until completely dissolved before dosing. |
| Liquid PAFC Solution | Feed directly or dilute down to a 10% – 20% concentration. | Meter straight into the flash mixing zone using corrosion-resistant pumps. |
Step-by-Step Treatment Process
- Rapid Mixing (Flash Mix): Dosing Polymeric Aluminum Ferric Chloride directly at a high-shear entry point (200–300 rpm for 1–2 minutes) guarantees quick charge neutralization.
- Flocculation (Slow Mix): Reduce mixing speed to 30–50 rpm for 10–15 minutes. The dual aluminum and iron polymer chains form dense, heavy flocs rapidly.
- Settling & Clarification: Allow 20–30 minutes of undisturbed settling time. Heavy flocs drop quickly, yielding high-clarity effluent.
Operating Notes for Stable Results
- Maintain Broad pH Control: PAFC operates reliably within a wide pH range of 5.0 to 9.0.
- Prepare Fresh Solutions: Diluted working solutions retain peak activity when used within 24 to 48 hours.
- Track Seasonal Variations: Adjust dosing pump rates during heavy rains or sudden drops in water temperature.
Common Application Mistakes to Avoid
- Dosing Dry Powder Directly: Never dump dry PAFC powder straight into raw water tanks; poor dispersion leads to severe chemical waste.
- Over-Dosing: Adding too much coagulant causes charge reversal, which restabilizes suspended solids and increases effluent turbidity.
- Insufficient Rapid Mixing: Weak flash mixing prevents the chemical from interacting with all suspended particles, resulting in fragile pin-flocs.
- Using Non-Resistant Pipework: Liquid PAFC solutions require acid-resistant dosing lines and pumps (such as PVC, PE, PTFE, or FRP).
