((1) Ionic Type Selection

PAM kationik (CPAM)

Lɔ̈ɔ̈m: Lɔ̈ɔ̈m dɔ̈ɔ̈r (cït mɛn, pɛ̈i cï lɔ̈ɔ̈m dɔ̈ɔ̈r looi).

Luɔi: Aciɛ̈ɛ̈r colloids ye cɔl negatively charged neutralizes, aciɛ̈ɛ̈r ye cɔl sludge settling, ku aciɛ̈ɛ̈r ye cɔl moisture content (to ≤80%).

A leŋ bɛ̈ɛ̈i: Kɔc ye kɔc cɔl 'medium-high charge density' (6080%), kɔc ye kɔc cɔl 'molecular weight' (MW) 812 million.

A sɔɔl: MW dït (1015 million), 1030% hydrolysis.

PAM ye cïn ion (NPAM)

Lɔ̈ɔ̈i: pH cï rot waar wala cï rot waar, ka të cenë metal ions tɔ̈u thïn.

Luɔi: Luɔi në hydrogen bonding; ye luui në coagulants (cït mɛn, PAC).

((2) Molekul Weight (MW) Selection
