Product Overview

Cationic PAM for Sludge Dewatering

Cationic polyacrylamide (CPAM) carries positive charge groups that neutralize the negative surface charge of organic sludge particles — the key to efficient belt filter, centrifuge and screw press dewatering, and the standard choice for MBR (membrane bioreactor) sludge conditioning in municipal and industrial plants.

Choosing the right ionicity is critical: too low gives weak flocs and cloudy filtrate; too high wastes money and can re-stabilize particles. We supply 10, 20, 30, 40, 50, 60 and 80% charge grades, and our technical team helps you match grade to sludge with free samples and jar testing before you commit to volume.

FAQ

Cationic PAM — Common Questions

Which ionicity grade should I use for my sludge?
As a rule of thumb: digested sludge from municipal plants typically works at 20-40%; activated sludge at 30-50%; high-organic industrial sludge may need 50-60% or above. The reliable way is jar testing with your actual sludge — we provide free samples and will help you compare grades side by side.
Can I mix cationic PAM with PAC in the same process?
Yes — PAC (coagulant) and cationic PAM (flocculant) are commonly dosed in sequence: PAC first for charge neutralization, then cationic PAM for floc building. We supply both from one warehouse, so you can mix them in one container and simplify your sourcing.
What documents come with the shipment?
Every shipment includes COA (Certificate of Analysis) for the actual batch, MSDS, Commercial Invoice, Packing List, Bill of Lading, and Form E certificate of origin for ASEAN-China FTA preferential tariff — prepared for Vietnam and Indonesia import requirements.
What is the reference price of cationic PAM?
Reference FOB price is US $1,300–2,500 per metric ton (ionicity 10-80%, MW 6-12 million) — final quote depends on ionicity degree, order quantity and market. MOQ is 1 ton. We send a firm quote with COA, packing and freight options to your port within 48 hours.
