Improved process efficiency: In wastewater treatment plants, polyacrylamide helps increase the efficiency of sedimentation and filtration processes. Its ability to bind particles quickly and effectively ensures that water can be processed more efficiently, saving time and reducing operational costs.
Reduced chemical usage: Traditional water treatment methods often require large quantities of harsh chemicals to remove impurities. Polyacrylamide offers a more environmentally friendly alternative by reducing the need for additional chemicals and improving the overall efficiency of water treatment processes.
Soil stabilization: Polyacrylamide is also used in agriculture and construction for soil stabilization. It helps prevent erosion by binding soil particles together, particularly in areas that experience heavy rainfall or strong winds. It’s often applied to roads, dams, and construction sites to improve the integrity of the soil.
Enhanced oil recovery: In the oil and gas industry, polyacrylamide is used to increase the yield of oil recovery. When injected into oil wells, it improves the flow of oil by reducing water content, helping extract more oil from reservoirs.
Wastewater treatment: In industrial settings, polyacrylamide is used to treat wastewater, helping companies reduce pollutants before discharging water back into natural water bodies. This ensures compliance with environmental regulations and reduces the company’s environmental footprint.

Charge neutralization: The organic colloidal particles in the sludge usually carry a negative charge, while the Cationic Polyacrylamide molecular chains are equipped with positive charge groups such as quaternary ammonium salts. When Cationic Polyacrylamide is added to the sludge, the positive charge groups are attracted by electrostatic forces to the negative charges on the surface of the sludge particles, significantly reducing the electrostatic repulsion between the particles and causing the negatively charged suspended particles to lose their dispersion stability
Bridging adsorption: The long molecular chains of Cationic Polyacrylamide (with a molecular weight of 8 million - 15 million) further enhance the flocculation effect through adsorption bridging. A single Cationic Polyacrylamide molecule can simultaneously adsorb multiple sludge particles, forming a three-dimensional network structure, which causes the suspended particles to aggregate into larger particles and accelerate their sedimentation
Reaction precipitation: React with negatively charged dissolved substances to form insoluble precipitates.
Application of Polyacrylamide
Sludge dewatering: Cationic polyacrylamide used for mechanical dewatering of municipal sludge and industrial sludge , such as belt press filters, centrifuges, etc., which can reduce the viscosity of the sludge cake and improve the dewatering efficiency.
Organic wastewater treatment: Treating high-concentration organic wastewater from alcohol plants, meat processing plants, by neutralizing charges to remove suspended solids and chemical oxygen demand (cod).
Oil-containing wastewater treatment: In the treatment of oil extraction wastewater and oilfield reinjection water, it can reduce the oil content and prevent formation blockage.
Paper dry strength agent: Cationic polyacrylamide can form hydrogen bonds with fibers, increasing the connection force between fibers, significantly improving the dry strength of paper, enabling the paper to maintain shape stability during production and reducing damage.
Retention agent: Cationic polyacrylamide can promote the sedimentation of fibers and the separation of impurities through adsorption and bridging, improving the retention rate of pulp fibers and fillers, and reducing raw material loss and wastewater discharge.Promotes water separation, increases the drying speed of paper, and saves energy.
Textile printing and dyeing industry: Treating dye wastewater to reduce color and suspended solids content, and can also be used as softening agent and static prevention agent in the textile printing and dyeing process.
Mining and coal separation industry: Cationic polyacrylamide can be used as a clarifying agent for mine wastewater and coal washing wastewater, making the wastewater purified and achieving water resource recycling.
Water treatment plants: Cationic polyacrylamide used as a flocculant for water treatment in water plants using river water sources, with low dosage, good effect, and low cost. Especially when used in combination with inorganic flocculants, the effect is even better.
Production Process of Polyacrylamide
Acrylamide monomer preparation:
Acrylamide (c₃h₅no) is typically produced from acrylonitrile via a hydration reaction, using a catalyst (such as copper-based catalysts or microbial enzymes). This reaction converts acrylonitrile into acrylamide, which serves as the raw material for polymerization.
Polymerization process:
Conducted in an aqueous medium with initiators such as ammonium persulfate (aps) or redox systems. Acrylamide is polymerized in a water-in-oil emulsion, often used to produce high molecular weight pam. Acrylamide is dispersed in a non-solvent medium with stabilizers to control particle size.
Post-processing:
The gel is dried and ground into fine particles. The polymer remains in an oil-based emulsion for easy dispersion. The polymer is dissolved in water and sold as a liquid formulation.
Modification:
Produced by copolymerizing acrylamide with cationic monomers like dimethyl diallyl ammonium chloride (dadmac) or methacryloxyethyl trimethyl ammonium chloride (metac). Formed by copolymerizing with acrylic acid, sodium acrylate, or through post-hydrolysis.
