EverStar Group has been manufacturing industrial-grade and drinking water-grade Powder Polyaluminum Chloride for over 13 years. Our advanced production lines deliver consistent Al₂O₃ content of 28-31% and basicity of 40-90%, ensuring rapid flocculation across a wide pH range of 5.0-9.0. With a 5,000-ton inventory and EU REACH compliance, we provide factory-direct pricing and fast delivery to over 50 countries. Whether you need spray-dried powder for municipal drinking water or roller-dried variants for industrial wastewater, our in-house laboratory offers 24-hour custom formulation support to match your exact water chemistry.
What Is Powder Polyaluminum Chloride?
This progressed inorganic polymer coagulant bridges the crevice between conventional aluminum salts and present day water treatment requests. It shapes pre-polymerized aluminum hydroxide chains that neutralize colloidal particles and tie suspended solids into settleable flocs. You get speedier clarification, lower slime volume, and diminished chemical costs compared to customary alum or ferric salts.
The powder frame offers amazing capacity solidness and breaks up rapidly in dosing tanks. You can utilize it for drinking water filtration, mechanical prepare water, material coloring profluent, mash and paper process release, and metropolitan sewage treatment. It works viably indeed in cold water down to 5°C, making it solid year-round.

Core Advantages You Can Count On
Dosage Efficiency: You need 30-50% less product compared to aluminum sulfate for equivalent turbidity removal. This translates directly into lower chemical costs and reduced sludge disposal fees.
Wider pH Tolerance: Unlike alum that only works in the narrow 6.5-7.5 range, Powder Polyaluminum Chloride remains effective from pH 5.0 to 9.0. You save on pH adjustment chemicals and simplify your process control.
Negligible pH Drop: The buffering impact of pre-polymerized species implies less affect on water alkalinity. You dodge the require for supplemental caustic pop or lime in numerous Applications.
Lower Remaining Aluminum: Post-treatment aluminum levels remain well underneath 0.2 mg/L when dosed accurately, assembly strict drinking water guidelines and decreasing wellbeing concerns.
Cold Water Execution: Numerous coagulants lose action underneath 10°C. This item keeps up tall flocculation rates indeed at 5°C, guaranteeing steady execution through winter months.
Fast Disintegration: The fine powder scatters quickly in water, disposing of the require for long blending times or high-shear hardware. Your dosing framework runs more dependably with less clogs.
How to Use It Properly?
Break up the powder in clean water to make a 5-10% working arrangement. Continuously include powder to water, never the turn around, to avoid localized warm era. Mix tenderly for 5-10 minutes until completely dissolved.
Run a jolt test to discover your ideal dosage. Normal ranges are:
- Drinking water clarification: 5-30 mg/L
- Industrial wastewater: 20-80 mg/L
- High-turbidity raw water: 50-150 mg/L
Infuse the arrangement into rapid-mix zones with 30-60 seconds of incredible disturbance, taken after by 15-30 minutes of tender flocculation. Alter measurements based on turbidity, pH, temperature, and natural substance. Screen settled water clarity and remaining aluminum to fine-tune your process.
Quality Control You Can Trust
Every group experiences four-stage assessment some time recently shipment:
- Heavy Metal Screening: ICP-OES analysis verifies that arsenic, lead, and cadmium levels meet drinking water limits.
- Basicity Testing: We measure polymerization degree to ensure you get the bridging performance promised on the label.
- Al₂O₃ Verification: EDTA titration confirms the active ingredient concentration matches specifications.
- Dissolution Rate Check: Critical for automated systems, this test ensures 100% solubility with no nozzle fouling.
Our ISO 9001-certified research facility keeps up traceability from crude fabric to wrapped up item. Each holder incorporates a certificate of examination and bunch traceability code.
FAQ
Q: What is the contrast between spray-dried and roller-dried product?
A: Spray-dried PAC highlights littler molecule sizes, higher dissolvability, and lower insoluble matter, making it perfect for drinking water and exactness mechanical processes.
Q: How do I decide the ideal dosage?
A: A standard Jolt Test is required to recreate field conditions; measurements regularly run from 5-50 mg/L depending on crude water turbidity and COD.
Q: Does it work in low-temperature water?
A: Yes, the item keeps up tall action at temperatures as moo as 5°C, not at all like alum which loses efficiency.
Q: What is the rack life and capacity requirement?
A: It has a rack life of 2 a long time if put away in a cool, dry put; dampness must be maintained a strategic distance from to avoid caking.
Q: Why is the floc arrangement little in a few cases?
A: This more often than not demonstrates either dishonorable pH (ideal extend is 5.0-9.0) or an off base basicity review for the particular water chemistry; a higher basicity variation may be required for speedier bridging.
