Polyacrylamide, commonly known as PAM, is a versatile water-soluble high polymer extensively utilized across various industries, including water treatment, paper-making, mining, oil & gas, and textiles. Among its different forms, the anionic type, Anionic Polyacrylamide Flocculant (A-PAM), stands out for its efficacy in separating solids from liquids, making it a cornerstone in numerous water purification and industrial process applications.

A-PAM functions primarily through two key mechanisms: flocculation and reinforcement. The flocculation mechanism involves the adsorption of suspended particles in water. The long polymer chains of A-PAM entangle and cross-link these particles, forming larger, heavier aggregates called flocs. This bridging process, combined with surface adsorption and electric neutralization of particle charges, leads to rapid sedimentation or easier filtration of the solid matter, significantly improving the clarity of the water.

Beyond simply aggregating particles, A-PAM also employs a reinforcing mechanism. In applications like sludge dewatering, the PAM molecule chains can form bridging bonds, ionic bonds, and covalent bonds with the dispersed solid phase. This enhances the mechanical strength and stability of the flocs or the dewatered sludge cake, improving dewatering efficiency and solids recovery.

The technical specifications of Anionic Polyacrylamide Flocculant are crucial for selecting the appropriate grade for specific applications. Typically, A-PAM presents as a white granule. Key parameters include a high molecular weight, often ranging from 5 to 22 million, which dictates the polymer chain length and its bridging capacity. The solid content is consistently high, generally 90% minimum, indicating a concentrated and potent product. Granule size is typically within the 20 to 100 mesh range, optimized for ease of dissolution. The degree of hydrolysis, which affects the anionic charge density, can vary, with common ranges being 10-20%, 20-30%, or 30-40%. Dissolution time into a working solution should be relatively quick, ideally within two hours at 10°C, to ensure efficient process integration. Impurity levels, such as insoluble matter and residual monomer, are kept very low (typically less than 0.5% insoluble and 0.05% monomer free) to ensure product purity and performance.

Anionic Polyacrylamide Flocculant finds widespread use in municipal and industrial water treatment facilities. It is highly effective in treating wastewater from diverse sources, including chemical plants, paper mills, textile factories, and mining operations. Its applications range from primary sedimentation to improve clarification, to sludge thickening and dewatering processes using belt presses, screw presses, or centrifuges. In the mining industry, it is vital for thickening tailings and clarifying process water, allowing for water recycling and reducing environmental impact. Paper manufacturers use A-PAM as a retention aid and drainage enhancer, improving paper quality and machine speed. It is also employed in potable water treatment to aid in the removal of suspended solids and turbidity, although specific grades and purity standards may apply.

Preparing the A-PAM solution correctly is essential for optimal performance. A working solution is typically prepared at a concentration of 0.1-0.3% solid content. The make-up water temperature should ideally be between 10°C and 40°C to facilitate proper dissolution. After dispersing the granules into agitated water, continuous stirring is recommended for approximately one hour to ensure complete hydration and polymer chain unwinding. Once prepared, the liquid polyacrylamide solution is generally stable for about one week, after which its viscosity and effectiveness may begin to degrade. Proper storage of the solid product is also crucial; it should be stored in a dry and cool warehouse to maintain its quality and ensure a shelf life of typically 24 months.
