Polyacrylamide (PAM)

High-molecular flocculant & thickener · cationic / anionic / nonionic

Description

A linear water-soluble polymer that flocculates through charge neutralization and bridging — the highest-volume flocculant in water treatment, paper, oil and mining.

Key Properties

High flocculation efficiency — low dosage, fast settling
Adjustable molecular weight to suit different solid-liquid separations
Selectable charge type: cationic, anionic, nonionic or amphoteric
Fast dissolution, easy to prepare solutions
Strong synergy with inorganic coagulants such as PAC and PFS

Applications

Sludge dewatering in municipal and industrial wastewater treatment
Flocculation and clarification in potable and circulating water
Strength aid, retention and drainage aid in papermaking
Drilling fluid viscosifier and enhanced oil recovery agent
Tailings settling and coal washing water treatment in mining

Packaging & Storage

Packaging: 25 kg PE-lined woven or paper-plastic laminated bag; jumbo bags on request.

Storage: Store sealed in a cool, dry place; protect from moisture and caking. Two years shelf life. Dissolve in ambient water, sprinkling slowly under agitation.

Handling & Safety

Dust is irritating. Avoid dust generation and wear a dust mask. Avoid prolonged high-shear agitation of solutions, which degrades the polymer.
