Did you know? Moisture can compromise the efficacy of
polyacrylamide. As a commonly used water purification agent, the effectiveness of polyacrylamide products is readily observable, even though they come into contact with water during use. Nevertheless, during storage, it is essential to keep them away from water sources and implement moisture-proof measures to prevent dampness. This prevents adverse effects on wastewater treatment outcomes and avoids wastage of polyacrylamide.
Generally, moisture-affected polyacrylamide presents in two forms. The first involves dampness that can be dispersed back to normal granules. This occurs because, despite being packaged in film bags, polyacrylamide is not vacuum-sealed. Contact with air causes clumping, though this is not genuine dampness but a normal phenomenon that does not impair performance. The other type involves genuine moisture absorption. When handled, it feels sticky and cannot be dispersed. This directly compromises the performance of the polyacrylamide. For clumped polyacrylamide, opening the packaging and kneading it can restore the original granules. However, if moisture-induced clumping makes dispersion difficult, the product may still be usable, albeit with reduced efficacy.
Polyacrylamide is a high-molecular-weight white granular substance. It is a high-quality water treatment product used in sewage treatment processes, exhibiting flocculation, sedimentation, and adsorption properties. It delivers excellent water treatment outcomes. However, improper storage may cause the product to clump or become sticky. Therefore, it must be stored in a dry, well-ventilated location to prevent moisture ingress. Prolonged storage can also diminish its efficacy. Consequently, purchasing quantities should be carefully planned according to anticipated usage requirements.
Polyacrylamide possesses positively charged particles on its ionic surface. With a high molecular content and significant molecular extension in water, it exhibits excellent flocculation properties. It effectively facilitates the sedimentation and separation of mineral suspended solids. Applications include wastewater treatment in industries such as iron smelting blast furnaces, aluminium processing, and papermaking. It is also utilised in municipal sewage treatment processes. The widespread industrial application of polyacrylamide stems primarily from its flocculation function, which efficiently extracts impurities from industrial wastewater. This effectively addresses contamination issues and significantly enhances wastewater treatment efficacy.
