Wholesale Anionic Polyacrylamide (APAM) Suppliers in China | High-Quality Flocculant Factory for Water Treatment Manufacturer, Factory

Anionic Polyacrylamide (APAM) is a highly effective water-soluble polymer characterized by its negatively charged molecular chains (-COO⁻). This polymer is essential for the electrical neutralization + adsorption bridging process, enabling it to interact effectively with positively charged suspended solids and colloidal particles in water, including sediment and iron hydroxide. APAM is crucial in efficiently coagulating and precipitating contaminants in high-turbidity environments, such as municipal sewage treatment, papermaking wastewater, and mining wastewater. As a leading product from China, our APAM is sourced from reputable suppliers and manufactured in our state-of-the-art factory, ensuring the highest quality and performance for all your water treatment needs

Product Description

Core Features

🎯 Precise Molecular Weight Control: The molecular weight of anionic PAM ranges from 12 million to 20 million (adjustable), with long and uniform molecular chains, showing significant flocculation effects on high-turbidity wastewater (turbidity ≤ 5000 NTU), and the turbidity removal rate is ≥ 95%.
⚡ Fast Dissolution, Low Residue: The dissolution time of powder PAM ≤ 60 minutes (at room temperature), after dissolution, the flocs are large and settle quickly (settling speed is 25%–40% faster than conventional products), and it works better when used in combination with PAC. Water insoluble matter ≤ 0.5%.

Application Area

🏙️
Municipal Sewage: Flocculation in the primary sedimentation tank and secondary sedimentation tank of urban domestic sewage treatment plants to reduce SS (suspended solids) to below 10 mg/L.
📄
Paper Mill Wastewater: Delignification of pulping black liquor, white water recovery (fiber collection rate increased by 15%–20%).
⛏️
Mine / Coal Washing Wastewater: Clarification of coal slurry water (collection rate of flotation clean coal increased by 8%–12%), flocculation and sedimentation in tailings pond.
🏗️
Building Materials Wastewater: Production wastewater from cement plants and ceramic factories removes suspended solids (turbidity reduced from 2000 NTU to 50 NTU).

Frequently Asked Questions

Q What is the molecular weight range of anionic PAM, and can it be customized?
Our anionic PAM (APAM) offers a molecular weight range of 12 million to 20 million. The molecular weight is adjustable based on your specific application requirements. Please contact us with your wastewater characteristics for a tailored recommendation.
Q What pH range is anionic PAM suitable for?
Anionic PAM is resistant to both acid and alkali environments, performing stably within a pH range of 5 to 10. It is effective in both high-alkalinity papermaking black liquor and low-pH mine acidic wastewater without corroding pipes or equipment.
Q How long does it take to dissolve powder anionic PAM?
Powder anionic PAM dissolves within ≤ 60 minutes at room temperature. After dissolution, it forms large flocs that settle 25%–40% faster than conventional products. For best results, it is recommended to use it in combination with PAC (Polyaluminum Chloride).
Q What industries can anionic PAM be applied to?
Anionic PAM is widely used in municipal sewage treatment, paper mill wastewater (pulping black liquor, white water recovery), mine and coal washing wastewater clarification, and building materials industry wastewater (cement plants, ceramic factories). It achieves turbidity removal rates of ≥ 95% in high-turbidity wastewater up to 5000 NTU.
Q What packaging options are available for anionic PAM?
We offer 25 kg woven bags lined with plastic inner bags, as well as 1-ton jumbo bags for bulk orders. Custom English labeling and customer logo packaging are also available upon request.
Q What are the storage requirements and shelf life of anionic PAM?
Anionic PAM should be stored in a cool, dry environment with temperatures not exceeding 35°C, away from direct sunlight and moisture. When stored unopened under these conditions, the shelf life of the solid powder product is 2 years.
