Anionic polyelectrolyte (APAM) manufacturer in India
Anionic polyelectrolyte is a high molecular weight anionic polyacrylamide flocculant, and we make it at our factory in Bharatpur, Rajasthan. We supply it as powder or granules in 25 kg HDPE bags, with a 250 kg minimum order. Sealed bags kept dry last up to 24 months. We sell it in India and export it too.
What is anionic polyelectrolyte?
It is a long-chain copolymer of acrylamide and sodium acrylate, sold abroad as anionic polyacrylamide (APAM) or anionic flocculant. The chains carry a negative charge and are long enough to bridge between particles, so the small flocs a coagulant such as ferric alum or PAC makes grow into large ones that settle fast. It works best on inorganic solids: clay, silt, mineral fines and the slurry from sand washing and mining. Organic sludge from sewage and biological treatment usually responds better to a cationic polymer, which we also make, so run a jar test before you switch. The powder is dissolved into a dilute stock solution and left to age before dosing. Added too fast, it forms lumps that do not fully dissolve.
Why Choose Rise Chemical India?
We make anionic polyelectrolyte in our own factory. It is packed in 25 kg HDPE bags. The 250 kg minimum lets a plant trial ten bags before setting a monthly schedule, and lets a plant add it to a ferric alum order. Sealed stock keeps for up to 24 months, so a larger lot does not go stale on the shelf. We are ISO 9001:2015 certified. Tell us what you are treating and which coagulant you use, and we will suggest a grade and quote.

Where anionic polyelectrolyte is used
Frequently Asked Questions
It is a flocculant that turns fine suspended solids into large flocs that settle or dewater quickly. Effluent plants dose it after a coagulant such as ferric alum or PAC. Mines and sand washing plants use it to recover water from slurries.
Anionic polyelectrolyte carries a negative charge and suits inorganic, mineral solids, while cationic carries a positive charge and suits organic sludge from sewage and biological treatment. The right one depends on the charge of the particles you need to remove. A jar test on your own sample decides it.
Yes, the anionic polyelectrolyte sold for water treatment is anionic polyacrylamide, a copolymer of acrylamide and sodium acrylate. Indian buyers call it polyelectrolyte, while importers in the Gulf and Africa usually search for APAM, PAM, anionic flocculant or anionic polymer.
The HS code is 3906.90 and the CAS number is 25085-02-3, the number for the acrylamide and sodium acrylate copolymer. CAS 9003-05-8, often quoted online, is non-ionic polyacrylamide. The product is not dangerous goods for shipping, and your customs broker should confirm the full tariff line for your country.
Yes, we export it. Send us the destination port, the quantity and your application, and we will reply with a quote; the price and terms depend on the quantity and the destination. We make it in our own factory, and it is packed in 25 kg HDPE bags. Contact us on WhatsApp at +91 95829 99838 or through the enquiry form.
Sprinkle the powder slowly into the vortex of stirred water to make a dilute stock, then let it age before dosing. Dumping it in at once forms lumps that do not dissolve and wastes product. Ask us for the stock strength and ageing time for your application.
Sealed bags stored dry keep for up to 24 months. The powder takes up moisture and cakes once a bag is open, so reseal it after each use and keep bags off damp floors.
