Product Introduction

Polyacrylamide, abbreviated as PAM, is a water-soluble linear polymer obtained by polymerizing acrylamide monomers. It appears as white granules or powder, odorless, easily soluble in water, and insoluble in most organic solvents. It is the most widely used flocculant, sedimentation, dewatering, and auxiliary filtration polymer in the water treatment field. By means of charge adsorption and bridging agglomeration, it condenses fine suspended particles and colloidal impurities in water into large flocs, rapidly precipitating and separating them, significantly reducing the SS, COD, and color of wastewater, and is widely applicable in the full range of municipal wastewater, industrial wastewater, and sludge treatment.

2. Product Material

High polymer organic polymer raw materials are divided into four core material types based on ionic properties: anionic, cationic, non-ionic, and amphoteric ionic. They feature high purity, fast dissolution speed, low dosage, strong flocculation effect, belong to environmentally friendly and non-toxic general goods, have no hazardous chemical properties, and are safe for storage and transportation.

Molecular Weight: 4 million – 10 million; low hydrolysis, weak electronegativity, suitable for acidic water quality and refined chemical wastewater.

(4) Amphoteric polyacrylamide

Yin-yang dual charge structure, adaptable to complex and variable water quality, and difficult industrial mixed wastewater.

General Packaging: 25kg/bag, available in powder/granule form.

4. Product Advantages and Features

• Extremely high flocculation efficiency and minimal dosage: The polymer chain bridging has strong adsorption capacity, requiring only trace amounts to quickly clump and settle, reducing the traditional dosage by over 50%.

• Fast sedimentation speed, thorough mud-water separation: The formed flocs are large, dense, and not easily broken, sedimentation is fast, the supernatant is clear, significantly improving the wastewater treatment efficiency.

•Broad water quality compatibility and strong specificity: The Yin and Yang models are precisely matched to different kinds of wastewater, capable of dealing with acidic, neutral, alkaline, high turbidity, high organic, and high sludge conditions.

•Combines dehydration, assist filtration, and thickening functions: Not only flocculates and purifies water, but also achieves sludge pressing and dehydration, papermaking retention aid, water body thickening, and drag reduction water purification.

• Excellent solubility, no residue pollution: Soluble in cold water, dissolves evenly without lumps, compliant addition without secondary pollution, does not affect subsequent water quality indicators.

• Outstanding cost-performance: Strong purification effect, low dosage, and low labor cost, suitable for continuous large-scale industrial wastewater treatment.

5. Core Functions

• FlocculationSettlement clarification: Adsorbs suspended particles, colloids, silt, and floating matter in water, agglomerates for sedimentation, reduces turbidity, SS, and COD.

Sludge Dewatering and Drying: Breaks the colloidal structure of sludge, expels moisture, and allows loose sludge to form dense sludge cakes, significantly reducing the moisture content of sludge.

• Decolorization and purification: Adsorbs water body pigments and organic impurities, removes dyeing and chemical wastewater color, enhances water clarity.

• Aid Filtration Solid-Liquid Separation: Used in the papermaking and mineral processing industries to enhance filtration speed and reduce material loss.

• Drag reduction, thickening, water stabilization: Reduces the frictional resistance of water flow, used in oilfield, industrial water circulation stabilization, and thickening for stability.
