Nantong, China - As global demand for clean water increases, the use of chemical flocculants has become essential in treating wastewater. Among these, polyacrylamide (PAM) is a versatile and highly effective polymer. But did you know that not all PAM is the same? The key to successful water treatment often lies in choosing the right type of PAM for a specific application. Let’s break down the science behind anionic and cationic polyacrylamide.

At its core, polyacrylamide works by promoting a process called flocculation. Wastewater contains tiny particles (suspended solids, colloids) that are difficult to remove. These particles often have a negative charge, causing them to repel each other and remain suspended. PAM, a long-chain polymer, acts like a magnet, neutralizing these charges and causing the particles to stick together to form larger, heavier clumps called "flocs." These flocs can then be easily removed through sedimentation or filtration.

The difference between anionic and cationic PAM lies in their molecular charge.

• Anionic Polyacrylamide: This type has a negative charge. It’s most effective in treating wastewater that contains positively charged suspended solids, such as those found in mining, mineral processing, and industrial wastewater from steel mills. Anionic PAM is excellent for clarifying water, promoting particle settling, and is highly cost-effective for large-volume applications.

• Cationic Polyacrylamide: This type has a positive charge. It's the go-to choice for applications with negatively charged particles, especially in sludge dewatering. Industries like municipal wastewater treatment plants, paper mills, and dyeing factories rely on cationic PAM to efficiently separate water from solids, significantly reducing the volume of sludge for disposal and lowering costs.

At Jiangsu Hengfeng Fine Chemical Co., Ltd., we specialize in manufacturing a full range of polyacrylamide products, providing the right solution for your specific water treatment challenge.
