What Is Anionic Polyacrylamide (APAM) Flocculant?

Anionic Polyacrylamide (APAM) is a high-molecular-weight water-soluble polymer synthesized through the co-polymerization of acrylamide and anionic monomers. With a molecular weight typically ranging from 8 to 20 million Daltons and a hydrolysis degree of 10%–60%, APAM carries a net negative charge that enables it to interact powerfully with positively charged suspended particles, colloids, and fine solids present in water systems.

As one of the most widely adopted flocculants globally, APAM works through a combination of charge neutralization, bridging, and adsorption mechanisms to aggregate dispersed particles into large, rapidly settling flocs — dramatically reducing turbidity, TSS (Total Suspended Solids), and colloidal contamination across a broad range of industrial and municipal applications.

💡 APAM flocculants can achieve TSS removal efficiencies exceeding 95% in optimized water treatment systems, making them the benchmark solution for suspended solids control.

Available in powder, granule, and emulsion forms, APAM flocculants offer flexible dosing options suited to both large-scale municipal plants and compact industrial installations. Smedic Technology's APAM products are formulated with precise charge density and molecular weight control to deliver consistent, high-performance flocculation under variable water quality conditions.

Mechanism of Action

How APAM Removes Suspended Solids

Understanding the four-stage flocculation process helps engineers optimize APAM dosing for maximum suspended solids removal efficiency.

1

Dissolution & Activation

APAM powder is dissolved in clean water (0.1%–0.3% solution) under agitation, allowing polymer chains to fully uncoil and activate their functional anionic groups for maximum reactivity.

2

Charge Neutralization

Anionic polymer chains adsorb onto positively charged suspended particle surfaces, neutralizing repulsive electrostatic forces that normally keep fine particles dispersed in water.

3

Bridging & Aggregation

Long polymer chains simultaneously bind multiple particles, forming a molecular "bridge" that draws fine suspended solids together into large, dense floc structures with rapid settling velocity.

4

Sedimentation & Separation

Enlarged flocs settle rapidly under gravity or are separated by filtration, DAF, or centrifuge, yielding clarified effluent with dramatically reduced TSS, turbidity, and COD values.
