Pam ngokwelashwa kwamanzi
Ukuqalisa
I-Pam (PolyAcrylamide) uhlobo lwe-polymer olusetshenziswa kwizicelo ezahlukahlukene, kufaka phakathi ukwelashwa kwamanzi. I-PolyAcrylamide imvamisa isetshenziswa njenge-flocculant ezinqubweni zokwelashwa kwamanzi ukwenza ngcono ukulungisa izinhlayiya ezimisiwe, okwenza kube lula ukuhlukanisa ama-solids emanzini.
I-PolyAcrylamide (Pam) iyingxenye ye-polymer esetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi. Iza ngezinhlobo eziningi ezahlukene, kufaka phakathi i-nonion, i-catioc, ne-anionic.

Izinja
I-Floculant:I-PolyAcrylamide imvamisa isetshenziswa njenge-flocculant ekwelashweni kwamanzi ukususa ama-solids amisiwe, udaba lwama-corloids nama-colloids bese uwasusa kuma-flocs amakhulu ukwenza lula ukufundwa okulandelayo noma ukufombula. Lokhu kufakelwa kusiza ukuthuthukisa ukucaciswa kwamanzi nokubonakala.
I-Endusnitant Enhancer:I-PolyAcrylamide ingakha izakhiwo ngensimbi yama-ion ukuthuthukisa umphumela we-precipitant. Lapho ukwelapha amanzi angcolile aqukethe i-metal ion, ukusetshenziswa kwePoliyacrylamide kungathuthukisa umphumela wezulu futhi kunciphise okuqukethwe ama-ion wensimbi kumanzi angcolile.
I-antiscalarant:Enqubweni yokwelashwa kwamanzi, i-polylacrylamide nayo ingasetshenziswa njenge-inhibitor yesikali ukuvimbela ukukala ngaphezulu kwamapayipi nemishini. Kuthuthukisa ukulingana kwamanzi, kuvimbela ukubekwa kwezinto ezincibilikisiwe emanzini, futhi kunciphisa ukwakheka kwesilinganiso.
Ukuthuthukiswa Kwekhwalithi Yamanzi:I-PolyAcrylamide nayo ingasetshenziswa ukwenza ngcono ikhwalithi yamanzi kwezinye izimo, njengokukhulisa izinga lokudonsela phansi ama-solids emanzini, kunciphisa ukwakheka kwe-sludge, njll.
Ukuqina kwenhlabathi:Ekuqinisweni kwenhlabathi kanye nokwenza ngcono, i-polylamide ingasetshenziswa ukuthuthukisa ukuqina nokuphikiswa kokugqwala kwenhlabathi, ngaleyo ndlela kuthuthukise izakhiwo ezibonakalayo zenhlabathi.
Kumele kwaziwe ukuthi umthamo we-polyracrylamide kufanele alawulwe ngokucophelela ngesikhathi sokusebenzisa ukugwema imiphumela emibi emvelweni. Ngaphezu kwalokho, uhlelo lokusebenza oluthile luncike kwizidingo ezithile zokwelashwa kwamanzi nezimpawu zekhwalithi yamanzi.
