1. Prinsip Teknik

Mekanism flocculation:

PAM's active groups (CONH) ₂) Adsorbe onto coal slurry particles, neutralizing surface charges and forming "bridges" to aggregate fine particles into larger flocks for rapid settlement.

Anionic PAM (APAM): A cɔl alkaline wastewater (ye kɔc cɔl coal washing) ye kɔc cɔl negative charged particles.

Non-ionic PAM (NPAM): A luɔ̈ɔ̈i në pi ye cɔl neutral wala acidic ye cɔl wastewater.

Cationic PAM (CPAM): A ye tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u ka tɔ̈u.
