The Manufacturing Process of Poly Aluminum Chloride

The production of Poly Aluminum Chloride (PAC), a key product offered by many aluminium chloride suppliers, involves a precise chemical synthesis to achieve desired performance characteristics. The primary raw materials are typically calcium aluminate powder, bauxite, aluminum hydroxide, and hydrochloric acid. The process is meticulously controlled to ensure product purity and effectiveness.

Manufacturing Process Steps:

1. Raw Material Preparation: High-grade aluminum-containing materials (e.g., aluminum hydroxide, bauxite) are carefully selected and pulverized to ensure optimal reaction surface area. Hydrochloric acid (HCl) of a specific concentration is also prepared.
2. Reaction and Polymerization: The aluminum-containing material reacts with hydrochloric acid under controlled temperature and pressure in specialized reactors. This acid-base reaction initiates the formation of aluminum chloride monomers, which then undergo polymerization to form the complex polymeric structure of PAC. Precise control over reaction conditions is crucial for achieving the desired basicity and Al2O3 content.
3. Filtration and Purification: The resulting poly aluminum chloride solution is then filtered to remove any insoluble impurities, ensuring a clean and stable product. This step is critical for preventing blockages in dosing equipment and maintaining product efficacy.
4. Concentration and Stabilization: For liquid PAC, the solution is concentrated to the desired Al2O3 percentage. For solid PAC, further drying processes, such as spray drying, are employed to produce a powdered or granular form. Stabilizers may be added to enhance shelf life and maintain product integrity during storage and transport.
5. Quality Control and Testing: Throughout the process, rigorous testing is conducted. This includes checks for Al2O3 content, basicity, pH, insoluble matter, and heavy metals. Compliance with international standards such as ISO 9001 for quality management and ANSI/AWWA B408 for PAC ensures product reliability and safety for target industries like municipal water supply & drainage, petrochemical, and metallurgy. Testing methods often include titration, gravimetric analysis, and ICP-OES for trace elements.
6. Packaging: The finished product is packaged according to client specifications, typically in bulk liquid container111s (IBCs, tanker trucks) or various sizes of bags for solid forms, ensuring safe handling and long service life.

Advantages inherent in a well-controlled manufacturing process include enhanced product purity, consistent performance, and optimized coagulation kinetics. This leads to energy saving in subsequent filtration steps and superior corrosion resistance for treated infrastructure due to reduced chemical aggressiveness.

Technical Specifications and Parameters of PAC Poly Aluminum Chloride

Understanding the technical specifications of poly aluminum chloride is critical for optimal selection and application. Key parameters dictate its performance as a coagulant. Reputable aluminium chloride suppliers provide detailed data sheets for their products, ensuring transparency and aiding in product matching.

The selection of PAC with appropriate basicity and Al2O3 content is crucial for optimizing coagulation efficiency. Higher basicity PAC typically performs better in water with low turbidity and alkalinity, while lower basicity is more suited for high turbidity water.

Diverse Application Scenarios of Poly Aluminum Chloride

PAC's versatility makes it indispensable across numerous industrial and municipal applications. Its ability to effectively coagulate suspended solids, colloidal matter, and various pollutants positions it as a preferred choice for many entities seeking reliable aluminium chloride suppliers.

• Municipal Water Treatment: PAC is extensively used in potable water treatment plants for raw water clarification. It effectively removes turbidity, color, algae, and suspended solids, ensuring compliance with drinking water standards. Its wide effective pH range (5.0-9.0) and rapid floc formation reduce treatment time and chemical consumption.
• Industrial Wastewater Treatment: From textile dyeing to mining and petrochemicals, PAC is crucial for treating process wastewater. It is highly effective in removing heavy metals, dyes, oils, and other organic pollutants, helping industries meet discharge regulations. Specifically, polyaluminum chloride water treatment systems are adept at handling effluents with variable compositions.
• Paper and Pulp Industry: PAC serves multiple roles, including retention aid for fine fibers and fillers, sizing agent, and wastewater treatment for effluent from paper mills. It improves paper quality and reduces environmental impact.
• Oil and Gas Sector: In upstream and downstream operations, polyaluminum chloride coagulant is used for demulsification of oil-water emulsions and clarification of produced water, facilitating efficient separation and safe discharge.
• Mining and Metallurgy: It aids in the clarification of mineral processing wastewater, tailings pond treatment, and removal of heavy metal ions, contributing to environmental protection and resource recovery.
• Pharmaceutical and Food Processing: While requiring specific food-grade or pharma-grade variants, PAC can be used in certain clarification steps to remove impurities, ensuring product quality and safety.

These diverse applications highlight PAC's role in promoting sustainable industrial practices and safeguarding public health through effective water management.

Technical Advantages of Poly Aluminum Chloride

Compared to traditional coagulants like aluminum sulfate or ferric chloride, PAC offers several significant technical advantages, making it a superior choice for many advanced water treatment systems.

• High Coagulation Efficiency: PAC's polymeric structure allows for rapid and robust floc formation, even at lower dosages. Its multi-nuclear complexes effectively neutralize colloidal charges and bridge particles, leading to superior turbidity and suspended solids removal.
• Wide Effective pH Range: Unlike conventional coagulants that perform optimally in a narrow acidic pH range, PAC is effective over a broader pH spectrum (typically 5.0 to 9.0), reducing the need for extensive pH adjustment and associated chemical costs.
• Lower Dosage Requirement: Due to its higher charge density and polymeric nature, PAC typically requires significantly lower dosages than traditional coagulants to achieve the same or better treatment outcomes, leading to cost savings and reduced chemical storage.
• Reduced Sludge Volume: Lower dosage translates directly into less sludge generation. This is a critical advantage for industries facing high sludge disposal costs and environmental regulations. Estimates suggest PAC can reduce sludge volume by 20-50% compared to alum.
• Less Alkalinity Consumption: PAC hydrolyzes less readily than conventional coagulants, consuming less of the water's natural alkalinity. This minimizes the need for alkalinity supplementation, further reducing operational costs.
• Improved Cold Water Performance: PAC maintains its excellent coagulation performance even in low-temperature water, a common challenge for traditional coagulants during winter months.
• Reduced Residual Aluminum: Properly applied PAC results in lower residual aluminum concentrations in treated water, which is important for health and environmental considerations.

These advantages collectively contribute to a more efficient, cost-effective, and environmentally friendly water treatment process, reinforcing the value proposition from expert aluminium chloride suppliers.
