I-Polyacrylamide (PAM) yenye yezona flocculants zisetyenziswa kakhulu ekucoceni amanzi kwimizi-mveliso. I-PAM idlala indima ebalulekileyo ekuhlukaniseni ulwelo oluqinileyo, ukususa amanzi odaka, kunye nokucocwa kwamanzi.
Nangona kunjalo, ukukhetha uhlobo olufanelekileyo lwe-PAM akulula njengokukhetha imveliso eqhelekileyo. Ukukhetha okungalunganga kunokukhokelela ekusebenzeni kakubi, ukunyuka kweendleko, kunye nokungasebenzi kakuhle kokusebenza. Kubasasazi, abathumeli, kunye nabathengi bemizi-mveliso, ukuqonda indlela yokukhetha i-PAM efanelekileyo kubalulekile ukuze kufezekiswe iziphumo ezilungileyo.
Kule khokelo, siza kuchazaiingcebiso ezi-5 ezisebenzayo eziphambiliukukunceda ukhethe iPolyacrylamide efanelekileyo kwiimfuno zakho zonyango lwamanzi kwimizi-mveliso — ngelixa uqinisekisa ukusebenza kakuhle, ukusebenza kakuhle kweendleko, kunye nokuthobela imigangatho yanamhlanje yokusingqongileyo.
I-Polyacrylamide (PAM): Isishwankathelo esifutshane
Ngaphambi kokuba ungene kwiingcebiso zokukhetha, kubalulekile ukuqonda ukuba yintoni i-PAM kunye nendlela esebenza ngayo.
I-Polyacrylamide yi-polymer eyenziweyo eyenziwe ngee-acrylamide monomers. Isetyenziswa kakhulu njenge-flocculant okanye i-coagulant aid, inceda amasuntswana amancinci axhonyiweyo ukuba ahlangane abe zii-floc ezinkulu ezinokususwa ngokulula.
Iintlobo eziphambili ze-PAM:
- I-Anionic Polyacrylamide(APAM) – itshajwe kakubi
- I-Cationic Polyacrylamide(CPAM) – itshajwe kakuhle
- I-Nonionic Polyacrylamide (NPAM) – itshaja engathathi cala
Uhlobo ngalunye luyilelwe iimeko ezahlukeneyo zekhemistri yamanzi kunye neenjongo zonyango.
Icebiso 1: Tshatisa uhlobo lwe-PAM kunye neKhemistri yamanzi
Eyona nto ibalulekileyo xa ukhetha i-PAM bubunjani bamanzi amdaka okanye amanzi asetyenziswayo.

Izikhokelo Zokukhetha Ngokubanzi:
| Uhlobo Lwamanzi | I-PAM ecetyiswayo |
| Amanzi amdaka angaphiliyo (isanti, udongwe) | I-Anionic PAM |
| Udaka oluvela kwindalo (umasipala, ukucubungula ukutya) | I-Cationic PAM |
| Iinkqubo ezingathathi cala okanye ezintsonkothileyo | I-PAM engeyiyo i-ionic |
Ukuba itshaja ye-PAM ayihambelani netshaja yamasuntswana, ukusebenza kakuhle kwe-flocculation kuya kwehla kakhulu. Umzekelo:
- Ukusebenzisa i-APAM kwinkunkuma yendalo kunokubangela ukwakheka kwefloc ebuthathaka
- Ukusebenzisa i-CPAM emanzini amdaka eeminerali kunokubangela idosi egqithisileyo kunye nenkcitho yeendleko
