NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present its High Molecular Weight Cationic Polyacrylamide, a leading solution for enhancing solid-liquid separation in various industrial and municipal applications. This product, a water-soluble polymeric electrolyte, is specifically designed to address complex challenges in water treatment and sludge management.

Characterized as a white granular powder, High Molecular Weight Cationic Polyacrylamide possesses active groups with a significant positive charge. This inherent characteristic enables it to function as a highly effective flocculating agent. It readily dissolves in water, facilitating ease of application, yet remains insoluble in common organic solvents like ethanol and acetone. Its formulation is innocuous, colorless, and flavorless, although it does exhibit a tendency to absorb moisture.

The principal utility of this cationic polyacrylamide lies in its ability to improve separation processes. It is widely applied in the dewatering of municipal and industrial wastewater sludges, including wood pulp suspensions, utilizing equipment such as belt presses, screw presses, filter presses, and centrifuges. Furthermore, it is invaluable in the thickening and clarification of wastewater sludges, food wastes, and paper fines through gravity settling, air flotation, and centrifugation methods.

Using High Molecular Weight Cationic Polyacrylamide offers several significant advantages. It is remarkably economical due to its effectiveness at very low dosage levels, leading to reduced handling and storage costs. In gravity settling operations, it promotes faster settling of sludge solids and significantly improves the clarity of the supernatant liquid. For belt presses, it increases filtration rates and yields drier sludge cakes. Centrifuges benefit from drier sludge cakes, greater throughput, increased solids recovery, and clearer centrates. Air flotation systems achieve clearer underflows, higher throughput, and increased float-cake solids. Even sand drying beds see improvements with greater bed loadings and faster drying rates. Importantly, the product is non-corrosive, contributing to equipment longevity and safety.

Proper preparation is key to optimizing performance. The polymer should be dissolved in water under low agitation to achieve a solution concentration between 0.01% and 0.05%. Full dissolution is typically achieved within 60 minutes, with warmer water potentially accelerating the process, though temperatures exceeding 50°C should be avoided. For optimal results, further dilution with clean water is recommended before introducing the solution into the process stream. It is crucial to avoid turbulent mixing conditions in the process stream after the cationic flocculant has been added to preserve floc integrity.

Typical treatment levels vary depending on the specific application. For dewatering processes involving municipal or industrial wastewater sludge using belt presses, screw presses, filter presses, or centrifuges, dosage rates typically range from 0.1% to 1% based on the dry solid content. In air flotation of activated sludge or paper mill fines, treatment levels are usually between 0.1 ppm and 5 ppm. Similarly, for thickening, clarification, or treatment of elutriated, digested primary, and waste activated sludge, dosage falls within the 0.1 ppm to 5 ppm range.

Handling the material requires care due to its hygroscopic nature; exposure to air should be minimized. Spilled polymer is very slippery and should be carefully scooped or wiped before attempting to flush with water to prevent slips and falls.
