Emkhakheni wokuhlanza amanzi, ukufuna amanzi okuphuza ahlanzekile naphephile kubalulekile. Phakathi kwamathuluzi amaningi atholakalayo kulo msebenzi,i-polyacrylamide(PAM), eyaziwa nangokuthi i-coagulant, igqama njenge-ejenti eguquguqukayo nesebenzayo. Ukusetshenziswa kwayo enkambisweni yokwelashwa kuqinisekisa ukususwa kokungcola nokungcola, ngaleyo ndlela kuthuthukise izinga lamanzi okuphuza. Lesi sihloko sicubungula ukusetshenziswa okuhlukahlukene kwe-polyacrylamide ekwelashweni kwamanzi okuphuza, sicacisa indima yayo njengengxenye ebalulekile enqubweni yokuhlanza.
1. I-coagulationkanye ne-Flocculation
Esinye sezicelo eziyinhloko ze-polyacrylamide ekwelapheni amanzi okuphuza sisenqubweni ye-coagulation kanye ne-flocculation. I-coagulation ihilela ukuchithwa kwezinhlayiya ze-colloidal ngokufaka amakhemikhali, okwenza kube lula ukuhlanganisa kwawo. izinsiza ze-polyacrylamide kule nqubo ngokunciphisa ukukhokhiswa okungekuhle ezinhlayiyeni ezimisiwe, zithuthukise ukuhlanganisa kwazo zibe iziqhumane ezinkulu, ezilungisekayo. Kamuva, i-flocculation iqinisekisa ukwakheka kwama-flocs amakhulu futhi aminyene, angasuswa kalula ngezinqubo ze-sedimentation noma zokuhlunga.
2. Ukususwa Okuthuthukisiwe Kokungcola
i-polyacrylamide ithuthukisa ukusebenza kahle kokususa ukungcola okuhlukahlukene okukhona emanzini okuphuza. Ngokwenza kube lula ukwakheka kwama-flocs amakhulu, kuthuthukisa izinqubo ze-sedimentation kanye ne-filtration, okuholela ekususweni kahle kwezinto eziqinile ezimisiwe, izinto eziphilayo, kanye nama-microorganisms. Ukwengeza, i-PAM isiza ekukhipheni izinsimbi ezisindayo, njengomthofu ne-arsenic, ngokwenza ama-complexes ngala ma-ion, ngaleyo ndlela kuvinjwe ukusakazeka kwawo kabusha emanzini ahlanzekile.
3. Ukuncishiswa Kwezikhukhula
I-turbidity, ebangelwa izinhlayiya ezimisiwe emanzini, ayithinti nje kuphela ikhwalithi yobuhle yamanzi okuphuza kodwa futhi isebenza njengenkomba engaba khona yekhwalithi yamanzi. i-polyacrylamide inciphisa ngempumelelo i-turbidity ngokukhuthaza ukuhlanganisa izinhlayiya ezinhle zibe yizinhlayiya ezinkulu, ezihlala ngokushesha. Lokhu kubangela amanzi okuphuza acacile futhi akhangayo, ahlangabezane nezindinganiso zokulawula kanye nokulindelwe ngabathengi.
Sengiphetha, i-polyacrylamide (PAM) idlala indima ebalulekile ekwelapheni amanzi okuphuza, ihlinzeka ngezinzuzo eziningi ngokwemibandelaI-coagulation, ukususwa kokungcola, ukuncishiswa kwe-turbidity, ukususwa kolwelwe, nokulungiswa kwe-pH. Imvelo yayo eguquguqukayo nokusebenza kwayo kuyenza ibe ithuluzi elibalulekile ezikhungweni zokuhlanza amanzi ezilwela ukunikeza amanzi okuphuza ahlanzekile, aphephile, futhi ajabulisa ngobuhle kubathengi. Njengoba intuthuko kubuchwepheshe bokuhlanza amanzi iqhubeka nokuvela, i-polyacrylamide ikulungele ukuhlala iyisisekelo emzamweni wokuphathwa kwamanzi okusimeme nokuvikelwa kwezempilo yomphakathi.
