In wastewater treatment, sludge dewatering, and water purification processes, the choice of flocculant directly determines effluent quality and operational costs. Jinmai PAM (Polyacrylamide) has become a widely adopted solution for municipal wastewater plants, industrial facilities, and mining operations, thanks to its excellent flocculation performance and consistent product quality. As a high-quality water treatment chemicals manufacturer, Shandong Jinmai New Material Group Co., Ltd. has focused on the research, development, and production of polyacrylamide for many years, delivering efficient and cost-effective flocculants to customers worldwide.
Polyacrylamide (PAM) is a water-soluble polymer synthesized from acrylamide monomers. Jinmai PAM is available in four ionic types: anionic (for inorganic suspensions), cationic (for organic sludge dewatering), non-ionic (for acidic or neutral conditions), and amphoteric (for complex wastewater with difficult-to-treat characteristics). This broad range covers treatment scenarios from acidic to alkaline and from inorganic to organic pollutants.
The molecular chains of Jinmai PAM contain numerous active groups that quickly adsorb suspended particles in water, aggregating them into large, dense flocs through bridging action. Compared to traditional inorganic flocculants, Jinmai PAM produces flocs that settle much faster, with lower supernatant turbidity and smaller sludge volume, significantly shortening the treatment cycle.
Only a very small amount of Jinmai PAM is needed per ton of wastewater to achieve ideal flocculation results. This low dosage not only reduces chemical procurement costs but also decreases sludge production, lowering subsequent transportation and disposal expenses. The overall economic benefits are substantial.
Wastewater characteristics vary greatly across different industries and process stages. Jinmai offers a wide array of PAM grades, covering a broad spectrum of molecular weights and ionic charges. Whether it is high-concentration oily wastewater from steel mills, high-moisture biological sludge from municipal treatment, or acidic tailings water from mines, there is a dedicated grade available. This avoids the inefficiency and waste that come with a "one-size-fits-all" approach.
Jinmai employs fully automated production lines and a strict quality control system. Every batch undergoes comprehensive testing, including molecular weight, degree of hydrolysis, residual monomer content, and dissolution rate. Consistent product specifications mean customers do not need to frequently adjust their dosing processes, ensuring more reliable and stable operations.
Municipal Wastewater Treatment: Jinmai cationic PAM is used for excess sludge dewatering, significantly reducing cake moisture content and transportation costs; anionic PAM serves as a coagulant aid in primary settling tanks to improve SS removal.
Industrial Wastewater Treatment: In textile, papermaking, electroplating, and chemical industry wastewaters, Jinmai PAM works alongside coagulants to effectively remove color, COD, and heavy metal ions.
Mining Operations: Jinmai anionic PAM is applied in tailings thickening and process water clarification, increasing tailings density and recovering clear water for closed-loop water circulation.
Oilfield Applications: Jinmai PAM functions as a displacement agent and fracturing fluid additive, improving crude oil recovery rates and performing well in high-temperature, high-salinity reservoir conditions.
Drinking Water Treatment: Jinmai PAM is used in combination with polyaluminium chloride (PAC) to enhance flocculation, reduce effluent turbidity, and minimize residual aluminum.
Jinmai PAM should be dissolved in clean, neutral water at an appropriate concentration. The dissolution process requires gentle stirring to avoid high shear forces that can degrade the polymer chains. The prepared solution should be used within a reasonable time frame to maintain optimal flocculation activity. The selection of the appropriate ionic type and dosage should be determined through jar testing based on site-specific water quality conditions.
Jinmai PAM contributes to environmentally responsible water management by enabling efficient water recycling, reducing sludge disposal volumes, and lowering overall chemical consumption. Its high biodegradability and low residual monomer content minimize environmental risks, making it a sustainable choice for modern treatment facilities.
