1. Superior flocculation and sedimentation capabilities, fundamentally solving the solid-liquid separation problem.

PAM is a high-molecular polymer with numerous active functional groups (anionic, cationic, and nonionic) on its molecular chains, enabling it to rapidly adsorb suspended particles (such as sludge, colloids, and suspended solids) in wastewater:

Through adsorption bridging, it connects tiny dispersed particles into large flocs, significantly increasing particle settling velocity;

Through charge neutralization, it neutralizes the surface negative charge of colloidal particles in wastewater, breaking down the stability of the colloids and allowing them to quickly aggregate and settle.

Compared to traditional flocculants (such as alum and polyaluminum chloride PAC), PAM forms larger and denser flocs, with settling velocities several times higher, enabling rapid solid-liquid separation in wastewater and significantly improving the treatment efficiency of sedimentation tanks and filter presses.

2. Diverse Types, Adaptable to All Wastewater Treatment Scenarios and Water Qualities

PAM (Polymer Alcoholic Acid) is categorized by ionic type into anionic, cationic, nonionic, and amphoteric types. Different types are suitable for different wastewater qualities and treatment stages, covering almost all wastewater treatment scenarios:

Anionic PAM: Suitable for wastewater primarily composed of inorganic suspended particles (such as industrial wastewater, primary sedimentation tanks in municipal sewage, and coal washing/mineral processing wastewater). It has good salt tolerance and excellent flocculation and sedimentation effects.

Cationic PAM: Suitable for wastewater primarily composed of organic sludge (such as secondary sedimentation tanks in municipal sewage, and food/printing/papermaking wastewater). It also plays a role in sludge dewatering, allowing the sludge to form a filter cake and reducing its moisture content.

Nonionic PAM: Suitable for neutral/weakly acidic wastewater (such as chemical wastewater and electroplating wastewater). It has superior flocculation effects in water with low ion concentrations.

Amphoteric PAM: Suitable for complex water qualities (such as industrial wastewater with high salinity and large pH fluctuations). It combines anionic and cationic characteristics, making it more adaptable.

Furthermore, by adjusting the molecular weight (8 million - 25 million) and degree of hydrolysis, it can precisely match the treatment needs of different wastewaters, offering extremely high flexibility.

3. Extremely low dosage, high cost-effectiveness, and significantly reduced treatment costs.

PAM is a high-molecular-weight agent with a high content of active ingredients. The actual dosage is only 0.1-10 ppm (i.e., 0.1-10 grams per ton of wastewater), far lower than traditional flocculants (such as PAC, which typically have a dosage of 50-200 ppm).

Even though the unit price is higher than traditional flocculants, the extremely low dosage significantly reduces the reagent cost per unit of wastewater. Simultaneously, due to its high flocculation efficiency, it can reduce the footprint of sedimentation tanks and shorten treatment time, indirectly reducing equipment and operating costs. Overall, its cost-effectiveness is far superior to other flocculants.

4. Can be used in combination with other agents to enhance overall treatment effectiveness.

PAM is often used in combination with **inorganic flocculants (PAC, polyferric sulfate PFS, aluminum sulfate)** to form a classic combination of "inorganic flocculant + organic polymeric flocculant," achieving a synergistic effect: The inorganic flocculant first initially coagulates particles in the wastewater, forming micro-flocs;

PAM then bridges and flocculates these micro-flocs, forming large flocs. This reduces the dosage of PAM and makes the flocculation and sedimentation effect more stable, making it particularly suitable for treating wastewater with high turbidity and complex compositions.

This combination method is a mainstream wastewater treatment process, simple to operate, and requires no major equipment modifications.

5. Multifunctional, Covering All Stages of Wastewater Treatment

PAM is not only used for "flocculation and sedimentation," but also plays a role in multiple core stages of wastewater treatment, including sedimentation, filtration, sludge dewatering, and advanced treatment, providing a one-stop solution to multiple treatment pain points:
Primary/Secondary Sedimentation Tanks: Accelerates the settling of suspended particles, improves effluent clarity, and reduces effluent SS (suspended solids) levels;
Sludge Dewatering: Cationic PAM is the core agent for sludge dewatering, enabling rapid separation of sludge from water, reducing sludge moisture content from 98%-99% to 70%-80%, facilitating sludge transportation, landfill, or incineration;
Filtration: Enhances the interception capacity of filters, reduces filter media clogging, and extends filter backwashing cycles;
Advanced Treatment: Assists in removing pollutants such as phosphorus and COD from wastewater, helping effluent meet discharge standards (e.g., upgrading municipal wastewater to Class A standards).

6. Easy to operate, compatible with existing wastewater treatment equipment, requiring no major modifications

PAM is simple to use; it only needs to be prepared into a 0.1%-0.5% aqueous solution and quantitatively added to the wastewater via a dosing pump. No major modifications to existing wastewater treatment equipment (sedimentation tanks, filter presses, biological treatment tanks) are required.

Furthermore, PAM aqueous solutions exhibit good stability and a rapid reaction rate after addition (flocculation occurs within minutes). It also has a wide adaptability to the temperature and pH range of the treatment process (operating normally at pH 5-10), making it suitable for continuous and large-scale operation in industrial and municipal wastewater treatment plants.
