Nonionic Polyacrylamide Powder

Our Nonionic Polyacrylamide (NPAM) is a high-efficiency water-soluble polymer flocculant. It is specially developed for acidic wastewater treatment, food processing wastewater, electronic industry wastewater, and chemical fiber production wastewater treatment. With good flocculation under pH-neutral to acidic conditions, low sensitivity to inorganic salts, and excellent performance in physical solid-liquid separation, it can greatly improve suspended solids removal efficiency and reduce overall treatment costs. Widely used in pickling wastewater, fruit juice processing, electronics manufacturing, metallurgical processes, and printing & dyeing auxiliaries.

Performance Comparison

NPAM for Paper Mill Water Purification

Turns turbid paper white water into crystal-clear reusable water. Premium NPAM flocculation rapidly aggregates fibers and fillers, accelerating settlement for superior clarity. Ensures compliant discharge or efficient recycling.

NPAM for food factories water treatment

Utilizes NPAM for powerful flocculation to remove suspended solids, ensuring superior water purification. Ideal for food factory treatment, it produces clear, safe effluent that meets strict discharge and reuse standards.

NPAM for stone processing wastewater treatment

Leverages premium NPAM flocculation to rapidly settle stone powder and fines, dramatically enhancing water purification. Delivers crystal-clear recycled water for stone fabrication plants.

The use method of nonionic polyacrylamide

1.Wear protective equipment

Wear gloves, safety goggles, and a dust mask. Although nonionic PAM has low irritation, you should still avoid prolonged skin contact and prevent dust inhalation when handling the powder.

2.Prepare the dissolving tank and water

Use a clean plastic or stainless steel dissolving tank. Fill it with clean, neutral water (pH 6-8) with low hardness. Nonionic PAM is highly sensitive to water quality, and high-hardness water can severely affect its dissolution and performance.

3.Calculate and weigh the powder

Calculate the required amount based on the target concentration (typically 0.05%–0.3%). Nonionic PAM has a high molecular weight, so the dosage is usually lower than that of anionic PAM. Weigh the powder accurately to avoid waste or insufficient effect.

4.Add water first, then start mixing

Pour the prepared water into the tank, then start the mixer before adding the powder. Use a low-to-moderate stirring speed (150–300 rpm) — high speed can break the polymer chains and reduce the flocculation effect.

5.Sprinkle powder slowly and evenly

Sprinkle the powder slowly and evenly along the edge of the vortex, not directly into the center. Nonionic PAM is prone to forming undissolved clumps ("fish eyes") if added too quickly.

6.Keep mixing until fully dissolved

Continue stirring for 45–60 minutes. Stop stirring only when the solution is completely clear, with no visible particles or gel clumps. Do not stir at too high a speed, as this will degrade the polymer.

7.Let the solution mature

Let the solution stand for 30–60 minutes to ensure full hydration of the polymer chains. The maturing process is critical for nonionic PAM to reach its optimal performance.

8.Determine the dosage by jar tests

Conduct jar tests to find the optimal dosage. Nonionic PAM is often used for low-temperature or highly turbid water, so test different dosages and mixing times to achieve the best flocculation and clarification effect.

9.Add the solution to the treatment system

Add the matured solution to the treatment system, usually before the flocculation tank. Ensure sufficient mixing time to allow the polymer to fully contact and react with the suspended solids.

10.Use the solution promptly and clean the equipment

The prepared nonionic PAM solution is less stable than anionic solutions, so it is best used within 12 hours. After use, rinse the dissolving tank and mixer thoroughly with clean water to prevent residue buildup.

Application

Wastewater Treatment

Enhances flocculation and sedimentation of industrial and municipal wastewater, removing suspended solids and organic matter.

Paper Manufacturing

Improves pulp retention and paper strength, reduces water consumption, and ensures uniform paper quality.

Mining and Mineral Processing

Facilitates solid-liquid separation in mineral slurry, accelerating sedimentation and reducing tailings handling costs.

Oil and Gas Industry

Aids in drilling fluid treatment and oil-water separation, improving production efficiency and reducing water content in oil.

Textile and Dyeing Industry

Removes dyes and suspended solids from wastewater, enhancing effluent clarity and reducing pollution load.

Food and Beverage Processing

Clarifies beverages such as juice and beer by flocculating fine particles and turbidity.

Product Certification

Package and Storage

Dry Storage

Keep in a cool, dry, well-ventilated area. Moisture causes caking and reduces effectiveness.

Secure Packaging

Use sealed plastic or coated paper bags. Prevent spillage and exposure to air humidity.

Limited Shelf Life

Shelf life is typically 12–24 months. Use within this period for optimal flocculation performance.
