In the field of wastewater treatment,
PAM (polyacrylamide) is hailed as the gold standard among
flocculants. This seemingly ordinary white powder delivers remarkable results in purifying sewage. Today, let us explore this pivotal agent that transforms murky wastewater into clarity. What is
polyacrylamide?
Polyacrylamide (PAM) is a linear, water-soluble polymer. Its molecular chain contains numerous amide groups, which confer upon it a unique adsorption capacity. This enables it to ‘link together’ minute suspended particles in water, forming large flocs that readily settle.
PAM Family: Characteristics and Application Scenarios of Three Types Anionic
polyacrylamide 
Charge characteristics: The molecular chain carries a negative charge Applicable to: positively charged inorganic suspended solids Typical applications: metallurgical wastewater, mineral processing wastewater, sand washing wastewater Key advantages: Molecular weight up to 18 million, rapid floc formation Cationic
polyacrylamide Charge characteristics: The molecular chain carries a positive charge Applicable to: negatively charged organic suspended solids Typical applications: Municipal sewage, sludge dewatering, food processing wastewater Advantages and characteristics: Combines both charge neutralisation and adsorption bridging functions Non-ionic
polyacrylamide Charge characteristics: electrically neutral Applicable to: Complex water quality systems Typical applications: acidic wastewater, alkaline wastewater, high-salinity wastewater Advantages and characteristics: Wide pH applicability range (2–10), strong resistance to interference The Four Fundamental Principles of
PAM The adsorption bridging effect of PAM’s long molecular chains resembles a ‘multi-armed Kannon,’ capable of simultaneously adsorbing multiple suspended particles and constructing a three-dimensional network structure between them. Charge neutralisation eliminates repulsive forces between particles through electrostatic interaction, thereby promoting particle aggregation. The flocs formed by the sedimentation effect in the net effectively capture passing minute particles during their descent. Surface chemical active groups undergo specific adsorption with the particle surface, enhancing the bonding strength.
