I-PAM yokwelashwa kwamanzi
Isingeniso
I-PAM (i-Polyacrylamide) iwuhlobo lwe-polymer esetshenziselwa izinhlelo zokusebenza ezihlukahlukene, kuhlanganise nokwelashwa kwamanzi.I-Polyacrylamide ivame ukusetshenziswa njenge-flocculant ezinqubweni zokwelashwa kwamanzi ukuze kuthuthukiswe ukulungiswa kwezinhlayiya ezimisiwe, okwenza kube lula ukuhlukanisa okuqinile emanzini.
I-Polyacrylamide (PAM) iyinhlanganisela ye-polymer esetshenziswa kabanzi emkhakheni wokwelashwa kwamanzi.Iza ngezinhlobo eziningi ezahlukene, kufaka phakathi i-nonionic, i-cationic, ne-anionic.

Izinhlelo zokusebenza
I-Floculant:I-Polyacrylamide ivame ukusetshenziswa njenge-flocculant ekwelapheni kwamanzi ukuze isuse izinto eziqinile ezimisiwe, izinhlayiya zezinhlayiya nama-colloid futhi iwahlanganise abe ama-flocs amakhulu ukuze kube lula ukuvela kwenhlabathi noma ukuhlunga.Le flocculation isiza ukuthuthukisa ukucaca kwamanzi nokungafihli.
Isithuthukisi se-Precipitant:I-Polyacrylamide ingenza ama-complexes ane-ion yensimbi ukuthuthukisa umphumela we-precipitant.Lapho ukwelapha amanzi angcolile aqukethe ama-ion ensimbi, ukusetshenziswa kwe-polyacrylamide kungathuthukisa umphumela wemvula futhi kunciphise okuqukethwe kwe-ion yensimbi emanzini angcolile.
I-Antiscaant:Enqubweni yokwelashwa kwamanzi, i-polyacrylamide ingasetshenziswa futhi njenge-inhibitor yesikali ukuvimbela ukukala ebusweni bamapayipi nemishini.Ithuthukisa ibhalansi ye-ion yamanzi, ivimbele ukufakwa kwezinto ezincibilikisiwe emanzini, futhi inciphise ukwakheka kwesikali.
Ukuthuthukiswa kwekhwalithi yamanzi:I-Polyacrylamide ingase isetshenziselwe ukuthuthukisa ikhwalithi yamanzi kwezinye izimo, njengokwandisa izinga le-sedimentation yezinto eziqinile ezimisiwe emanzini, ukunciphisa ukwakheka kodaka, njll.
Ukuqiniswa komhlabathi:Ekuqinisweni nasekuthuthukisweni kwenhlabathi, i-polyacrylamide ingasetshenziswa ukuthuthukisa ukuzinza nokumelana nokugqwala kwenhlabathi, ngaleyo ndlela kuthuthukiswe izakhiwo ezibonakalayo zomhlabathi.
Kumele kuqashelwe ukuthi umthamo we-polyacrylamide kufanele ulawulwe ngokucophelela ngesikhathi sokusetshenziswa ukugwema imiphumela emibi emvelweni.Ngaphezu kwalokho, isicelo esithile sincike ezidingweni ezithile zokwelashwa kwamanzi kanye nezici zekhwalithi yamanzi.
