Polyacrylamide (PAM) is a highly versatile polymer with a broad range of applications, most notably in water treatment and various industrial processes. At NINGBO INNO PHARMCHEM CO.,LTD., we aim to demystify this essential chemical, providing clarity on its polyacrylamide chemical properties, types, and how to select the best product for your specific requirements.

PAM is a linear water-soluble polymer formed from acrylamide monomers. Its key characteristics include excellent flocculation, thickening, and adhesion properties. Depending on its ionic charge, PAM can be broadly classified into three main types:

1. Anionic Polyacrylamide (APAM): APAM has a negative charge and is highly effective in flocculating positively charged particles. It is widely used in the treatment of neutral to alkaline wastewater containing suspended solids, such as those found in industrial effluents from steel, electroplating, and metallurgical industries. Its performance is often enhanced when dealing with high concentrations of cations.

2. Cationic Polyacrylamide (CPAM): CPAM possesses a positive charge, making it ideal for flocculating negatively charged organic matter. This type is particularly renowned for its effectiveness in sludge dewatering, where it significantly reduces sludge volume and improves water release. It is a preferred choice for treating municipal sewage, industrial sludge, and in applications within the paper and textile industries.

3. Non-ionic Polyacrylamide (NPAM): NPAM has a neutral charge and primarily functions through bridging mechanisms. It is effective in accelerating clarification and filtration, especially in acidic conditions. NPAM is also utilized in the petroleum industry for its thickening and drag reduction properties, and in the paper industry as a dispersant.

The selection of the appropriate PAM type depends on several factors: the nature of the wastewater (pH, presence of charged particles), the specific application (flocculation, dewatering, thickening), and the desired outcome. For instance, when treating acidic wastewater or seeking improved filtration, NPAM might be the optimal choice. For general industrial wastewater with suspended inorganic solids, APAM often proves most effective. For organic-rich sludge, CPAM is usually the superior option.
