Dosage and Application Guidance for Polymeric Aluminum Chloride
Proper preparation and accurate dosing ensure you get maximum performance and cost efficiency from our Polymeric Aluminum Chloride in any treatment setup.
How to Prepare and Feed Polymeric Aluminum Chloride
To achieve quick flocculation and clear separation, follow these standard dilution and dosing guidelines:
- Polyaluminium Chloride Powder Dissolution: Dissolve the solid powder in clean water to make a 5% to 10% aqueous solution (by weight) prior to application. Stir continuously until the solution is uniform.
- Liquid Polyaluminum Chloride Feed: Dosing can be done directly from the storage vessel or diluted slightly to match the stroke capability of your metering equipment.
- Dosing Location: Inject the PAC solution directly into the rapid-mixing zone (flash mixer) using calibrated, corrosion-resistant dosing pumps to ensure instantaneous dispersion across the stream.
Determining the Recommended PAC Dosage
Because water parameters shift seasonally, exact feed rates depend on real-time water conditions. We always advise conducting a jar test prior to full-scale dosing to determine the optimal dosage point.
- Drinking Water Clarification: Typically 5 mg/L to 30 mg/L (ppm) of prepared solution, depending on raw water turbidity and color.
- Industrial Wastewater Treatment: Typically 20 mg/L to 100+ mg/L (ppm), depending on suspended solids, COD load, and target phosphorus levels.
Key Factors Impacting PAC Coagulant Performance
| Factor | Operating Impact & Guidance |
|---|---|
| Initial Water pH | Maintains strong performance across a wide pH range (5.0–9.0), requiring significantly less alkalinity adjustment than traditional alum. |
| Turbidity & Suspended Solids | High-turbidity water provides faster particle collision rates, accelerating initial micro-floc aggregation. |
| Water Temperature | Demonstrates superior coagulation speed in low-temperature and cold winter waters compared to monomeric aluminum salts. |
| Mixing Energy | Requires intense rapid mixing at the point of injection, followed by gentle, low-shear agitation in the flocculation basin. |
| Organic Load (NOM/COD) | Elevated natural organic matter increases chemical demand; jar tests help prevent under-dosing or charge reversal. |
