Polyaluminum Chloride (PAC) from factory East Chemsources-best price

Product Name: Polyaluminum Chloride (PAC)CAS No.: 1327-41-9Molecular Formula: [Al?(OH)?Cl???]? (n=1-5, m≤10)Product Grade: Drinking Water Grade / Industrial GradeProduct Category: Emerging Water Purification Material, Inorganic Polymer Coagulant

1. Product Overview

Polyaluminum Chloride (PAC) is a high-efficiency inorganic polymer coagulant developed in recent decades. It is produced by the polymerization of aluminum chloride under specific conditions, forming a polymer with bridging hydroxyl groups. PAC features strong adsorption, rapid flocculation, large floc particle size, and fast sedimentation rate. Compared with traditional coagulants (e.g., aluminum sulfate, ferric chloride), it has advantages of wide pH adaptation range, low dosage, and minimal secondary pollution. It is widely used in drinking water purification, industrial wastewater treatment, and sewage sludge dewatering.

2. Physicochemical Properties

3. Quality Standards

• Drinking Water Grade: Complies with GB 15892-2020 (China National Standard for Drinking Water Treatment Chemicals)
• Industrial Grade: Complies with GB/T 22627-2014 (China National Standard for Polyaluminum Chloride for Industrial Use)
• Customizable to meet international standards or customer-specific requirements

4. Core Applications

1. Drinking Water Purification: Used for treating surface water (river, lake water) and underground water, effectively removing suspended solids, colloids, turbidity, and organic impurities; suitable for water plants of various scales.
2. Industrial Wastewater Treatment: Applied in treating wastewater from papermaking, printing and dyeing, electroplating, coal washing, chemical, and food industries; efficient in removing heavy metal ions, chroma, and COD/BOD.
3. Sewage Sludge Dewatering: Improves sludge dewatering performance, reduces sludge volume, and facilitates sludge transportation and disposal.
4. Other Applications: Papermaking sizing agent (improves paper strength and retention rate); ore dressing (flocculation and separation of ore pulp); wastewater reuse treatment system.

5. Storage and Transportation

• Storage Conditions: Store in a cool, dry, and well-ventilated warehouse; keep away from moisture, rain, and direct sunlight. The product is prone to caking when exposed to moisture, but the coagulation effect remains unchanged after dissolving.
• Packaging Specifications
  • Powder: 25 kg/bag (polypropylene woven bag with inner PE film); 500 kg/1000 kg/bulk bag.
  • Liquid: 25 kg/barrel, 200 kg/barrel (plastic drum); customizable to tank truck for bulk delivery.
• Transportation Requirements: Classified as non-hazardous chemical. During transportation, avoid mixing with acids, alkalis, and reducing agents; prevent package damage and leakage. Comply with local transportation regulations.
• Shelf Life: 12 months for powder; 6 months for liquid (under standard storage conditions, unopened original packaging).

6. Safety and Handling

1. Hazard Classification: Non-toxic, non-flammable, non-explosive chemical. Irritating to skin and mucous membranes at high concentrations.
2. Handling Precautions: Wear dust mask, protective gloves, and goggles during operation to avoid inhaling dust or contacting skin/eyes directly. Operate in a well-ventilated environment.
3. First-aid Measures
   • Skin contact: Rinse contaminated area with plenty of running water for 15 minutes; seek medical advice if irritation persists.
   • Eye contact: Immediately lift eyelids and rinse with plenty of running water or normal saline for 15 minutes; seek medical attention promptly.
   • Accidental ingestion: Drink plenty of warm water to induce vomiting (avoid vomiting for unconscious persons); seek medical treatment immediately.
4. Waste Disposal: Dispose of unused product and packaging in accordance with local environmental regulations; do not discharge directly into water bodies or soil.

7. Additional Information

• Synonyms: Poly Aluminium Chloride; PAC; Basic Aluminum Chloride
• Usage Tips: Dissolve the powder in clean water at a ratio of 5%–10% before use; the optimal dosage is determined by jar test according to water quality.
• Compliance Documents: Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and export-related documents can be provided upon request.
