Anionic Polyacrylamide (APAM) – Flocculant for Water Treatment
Anionic Polyacrylamide is an anionic flocculant featuring a linear chain structure, formed through the free-radical polymerization of acrylamide monomers. Typically appearing as white granules, it is a water-soluble polymeric solid powder. It possesses a wide range of functionalities, including flocculation, thickening, drag reduction, adhesion, colloidal stabilization, film formation, and scale inhibition.
The methods for preparing Anionic Polyacrylamide (APAM) are diverse, primarily encompassing solution polymerization, inverse emulsion polymerization, suspension polymerization, and solid-phase polymerization. An ideal product should exhibit a controllable molecular weight, excellent water solubility, and an extremely low residual monomer content.
APAM is suitable for applications involving high concentrations of positively charged inorganic suspended solids, as well as for neutral or alkaline environments containing relatively coarse suspended particles (ranging from 0.01 to 1 mm).
Preparation of Solution
Dissolve APAM in clean water to make a 0.1%–0.3% solution
Stir gently (avoid high-speed mixing to prevent polymer degradation)
Dosage
Typical dosage: 1–10 ppm (depending on water quality)
Optimal dosage should be determined through jar testing
Application
Add the solution evenly into the wastewater system
Ensure proper mixing for best flocculation results
Selection depends on:
- Water source and composition
- pH value
- Suspended solids concentration
- Treatment process
Jar testing is highly recommended.
