How Polymeric Aluminum Chloride Works & Performance Advantages
We design our Polymeric Aluminum Chloride to deliver rapid charge neutralization and superior particle bridging in raw water and wastewater stream treatment. As a pre-hydrolyzed inorganic polymer coagulant, PAC destabilizes negatively charged colloidal impurities far faster than monomeric salts, forming large, high-density flocs that settle rapidly.
Advanced Polymerization Hydrolysis
Our advanced polymerization hydrolysis process optimizes the active Al2O3 concentration and basicity ratio of the chemical structure. This delivers critical operational advantages:
- Superior Charge Neutralization: Highly charged polymeric aluminum species instantly neutralize surface charges on suspended solids, accelerating micro-floc formation.
- Broad Operational pH Range: Maintains peak coagulation efficiency across a 5.0 to 9.0 pH spectrum, drastically reducing the need for secondary pH adjustment chemicals.
- Cold-Water Reliability: Performs consistently in low-temperature water down to 0°C, preventing seasonal performance drop-offs.
Polymeric Aluminum Chloride vs. Traditional Aluminum Sulfate (Alum)
Replacing traditional alum with our high-performance PAC chemical coagulant directly lowers overall chemical usage, reduces sludge handling fees, and optimizes plant throughput.
| Performance Parameter | Polymeric Aluminum Chloride (PAC) | Traditional Aluminum Sulfate (Alum) |
|---|---|---|
| Required Dosage | 30%–50% lower required volume | High baseline chemical consumption |
| Floc Settling Speed | Rapid formation of dense, heavy flocs | Slower settling, fragile floc structure |
| Sludge Production | Up to 40% reduction in wet sludge mass | High sludge volume; higher disposal costs |
| Alkalinity Consumption | Minimal impact on treated water pH | Depletes alkalinity; requires caustic soda |
| Residual Aluminum | Consistently lower residual carryover | Higher residual aluminum risk in treated water |

Dosing Guidelines & Operational Best Practices
Optimizing Polymeric Aluminum Chloride performance requires precise solution preparation and system calibration. Our Greenlano technical engineering team provides direct operational parameters to help plant managers achieve rapid flocs and maximum turbidity removal while keeping chemical consumption low.
Solution Preparation & Dosing Ratios
We recommend preparing Polymeric Aluminum Chloride powder into a liquid stock solution prior to dosing into raw water streams.
- Solid PAC Dissolution: Dissolve solid PAC powder into water to create a 5% to 10% concentration (5–10 kg powder per 100 L water). Stir continuously for 10 to 15 minutes until fully dissolved.
- Liquid PAC (PAC-L): Can be fed directly into raw water lines using metering pumps or diluted to a 2% to 5% concentration for precise low-flow applications.
- Optimal Processing pH: Operates effectively within a broad pH range of 5.0 to 9.0, eliminating the need for heavy pre- or post-treatment pH neutralizers.
| Application Type | Raw Water Turbidity / TSS | Recommended Dosing Ratio (mg/L or ppm) | Stock Solution Strength |
|---|---|---|---|
| Potable / Drinking Water | Low to Moderate (< 100 NTU) | 5 – 30 mg/L | 5% liquid solution |
| Municipal Wastewater | Moderate (100 – 500 NTU) | 20 – 100 mg/L | 5% – 10% solution |
| Industrial Effluent | High (> 500 NTU / High COD) | 100 – 300+ mg/L | 10% liquid solution |
Jar Testing Protocol: Run benchtop jar tests before full-scale dosing to determine the precise active dosage. Inject Polymeric Aluminum Chloride at the rapid-mix zone (200 RPM for 1 minute), followed by slow mixing (30–40 RPM for 10–15 minutes) for optimal coagulation and flocculation.
Safe Handling, Material Compatibility & Storage
Liquid Polymeric Aluminum Chloride solutions are slightly acidic (pH 3.5–5.0). We mandate using corrosion-resistant equipment and proper storage facilities to ensure personnel safety and equipment longevity.
- Compatible Equipment Materials: FRP (Fiberglass Reinforced Plastic), HDPE, PP, PVC, rubber-lined steel, and 316 stainless steel for dosing lines and storage tanks.
- Incompatible Materials: Avoid direct contact with carbon steel, mild steel, aluminum, copper, and galvanized zinc surfaces.
- Storage Requirements: Keep solid powder bags in a dry, ventilated warehouse, stacked on wooden pallets off concrete floors. Tightly seal opened bags to prevent air moisture absorption and clumping.
- Product Shelf Life:
- Solid PAC Powder: 24 months from manufacturing date under sealed dry conditions.
- Liquid PAC (PAC-L): 6 months in UV-stabilized or indoor holding tanks.
- Personnel Safety: Handlers should wear standard PPE, including chemical goggles, nitrile gloves, and dust masks during bulk powder dissolution.
