China White Polyaluminium Chloride Manufacturers and Suppliers - Factory Direct Wholesale

Product Overview

White Polyaluminium Chloride (White PAC) is a high-purity, spray-dried inorganic polymer coagulant utilized primarily for potable water purification, high-grade paper sizing, and precision chemical applications. Distinguished by its exceptionally low iron content (Fe <= 0.005%), it prevents staining and discoloration in sensitive water and pulp processing environments.

Manufactured via high-temperature spray-drying technology, the product forms uniform, hollow microspheres that dissolve rapidly in water without leaving heavy sludge deposits. It functions effectively across a broad pH range (4.0 to 9.0) and lower water temperatures compared to traditional aluminum sulfate or ferric chloride. Supplying over 50,000 metric tons annually to municipal plants and industrial facilities across 30+ countries, Ecolink delivers consistent, scale-proven performance.

Key Features

Ultra-Low Iron Impurities:

Fe content capped at <= 0.005%, eliminating the risk of yellowing in paper products and discoloration in treated drinking water.

Rapid Dissolution Kinetics:

Spray-dried porous spherical morphology ensures complete dissolution within 3 minutes under standard mechanical agitation, preventing nozzle and dosing pump clogging.

Low Residual Aluminum:

Optimized bridging and charge neutralization mechanisms achieve high turbidity reduction without elevating residual soluble aluminum levels in finished potable water.

Wide Temperature Adaptability:

Maintains flocculation efficiency in cold water applications (<5°C) where conventional aluminum sulfate experiences reaction rate drop-offs.

Applications

Municipal Potable Water Treatment:

Acts as the primary coagulant for surface water and reservoir clarification, reducing turbidity from 50 NTU to below 1 NTU within 5 minutes, alongside organic matter and coliform loads prior to filtration.

Paper Manufacturing (Wet End):

Used as a sizing precipitant and retention aid in fine paper, cultural paper, and specialty paper production, improving filler retention and sheet formation without reducing paper brightness.

Cosmetic & Personal Care Ingredients:

Utilized as an astringent and active intermediate in specific antiperspirant and personal care formulations requiring high purity.

Industrial Process Water:

Applied in semiconductor rinse water pre-treatment and pharmaceutical purified water circuits to remove trace colloidal silica and suspended solids.

Product Selection Guide

Selecting the appropriate grade of Polyaluminium Chloride depends on raw water chemistry, target treatment standards, and dosing system constraints.

Raw Water Source / Application
Municipal Potable Water / Fine Paper --> Choose White PAC (High Purity, Low Fe)
General Industrial Wastewater --> Choose Yellow/Amber PAC (Cost-Effective, Higher Fe)
Heavy Sludge Dewatering --> Evaluate Dual-System (PAC + Anionic PAM)

When to choose White PAC: Required when treating potable drinking water, producing high-brightness paper, or operating in processes where iron leaching must be strictly avoided.

Dosing Optimization Benchmarks: Typical jar testing dosage ranges from 5 mg/L to 30 mg/L depending on raw water turbidity and total organic carbon (TOC) levels. Optimal coagulant performance occurs when jar tests confirm rapid micro-floc formation within 30 to 60 seconds and clear supernatant separation within 5 minutes.

Manufacturing & Quality Control

Production Process: Synthesized using high-purity aluminum hydroxide powder and hydrochloric acid via continuous digestion, high-efficiency polymerization, and closed-loop spray drying.

Equipment Infrastructure: Automated reaction kettles with precision temperature and pressure sensors; stainless steel atomizing spray-drying towers ensuring consistent particle size distribution.

In-House Analytical Testing: Every production batch undergoes rigorous laboratory verification via ICP-OES for heavy metal tracking, automatic potentiometric titration for basicity and Al2O3 validation, and laser particle sizing.

Traceability & Compliance: Manufactured under strict quality management protocols. Certificates of Analysis (COA) are archived for 5 years per batch number. Third-party testing reports (e.g., SGS, NSF/ANSI 60 compliance verification) available upon request.

Packaging & Supply Capacity

Standard Packaging Configurations:
25 kg polyethylene inner-lined woven bags or Kraft paper bags.
500 kg / 1000 kg jumbo bags (Super Sacks) with inner moisture-proof liners.

Logistics & Storage Protection: Palletized and stretch-wrapped with UV-resistant film for containerized maritime transport. Bags feature multi-layer moisture barriers to prevent caking in high-humidity storage conditions.

Frequently Asked Questions

Q: What is the primary difference between White PAC and Yellow PAC?

A: White PAC is manufactured from high-purity aluminum hydroxide, resulting in an aluminum oxide (Al2O3) content of >= 30% and an iron (Fe) content of <= 0.005%. Yellow or amber PAC typically uses calcium aluminate powder or bauxite as raw materials, containing higher iron levels (Fe >= 1.0%) and insoluble matter. White PAC is designated for potable water and high-brightness paper to avoid staining, whereas yellow PAC is optimized for industrial wastewater treatment.

Q: How does White PAC perform in cold water conditions (<5°C)?

A: Because White PAC is pre-hydrolyzed, its electrical charge neutralization and adsorption-bridging mechanisms are less dependent on water temperature compared to traditional inorganic salts like alum. It retains rapid floc formation kinetics in cold winter conditions, though an extended settling time or minor dosage adjustment may be verified via jar testing.

Q: What is the recommended shelf life and storage procedure?

A: White PAC is hygroscopic and will absorb moisture if exposed to open air. The unopened product has a shelf life of 24 months when stored in a cool, dry, well-ventilated warehouse away from direct sunlight and corrosive chemicals. Partial bags should be tightly sealed immediately after opening.

Q: Does White PAC require pH adjustment during municipal water treatment?

A: White PAC operates effectively over a wide pH range (4.0 to 9.0). However, optimal coagulation usually occurs between pH 6.5 and 7.5. For low-alkalinity raw waters, small amounts of lime or sodium hydroxide may be co-dosed to maintain buffering capacity and prevent treated water pH depression.

Q: Can this product be used directly in dosing systems without pre-dissolution?

A: No. White PAC powder must be pre-dissolved into a liquid solution (typically a 5% to 10% concentration) using mechanical agitation before injection into the main water pipeline. Direct dosing of solid powder will cause incomplete dissolution, high viscosity pockets, and pump line blockages.

Q: What shipping documents and compliance certifications are provided with each export shipment?

A: Each shipment includes a commercial invoice, packing list, Bill of Lading, Certificate of Analysis (COA) matching the specific batch number, and a GHS-compliant Safety Data Sheet (SDS). Additional destination-specific certificates (such as NSF/ANSI 60 statements or pre-shipment inspection certificates by SGS/BV) can be arranged prior to dispatch.
