Isebenza kanjani iPoly Aluminium Chloride?

Emhlabeni wokwelashwa kwamanzi,I-Poly Aluminium Chloride(i-PAC) ivele njenge-coagulant eguquguqukayo futhi ephumelelayo.Ngokusetshenziswa kwayo kabanzi ekuhlanzeni amanzi okuphuza nezindawo zokuhlanza amanzi angcolile, i-PAC yenza amagagasi ngekhono layo elimangalisayo lokucacisa amanzi nokususa ukungcola.Kulesi sihloko, sihlolisisa ukusebenza kwe-PAC kanye nokubaluleka kwayo emkhakheni wokuhlanza amanzi.

I-Chemistry Behind PAC:

I-Poly Aluminium Chloride iyikhemikhali eyakhiwe nge-aluminium ne-chlorine, enefomula ethi AlnCl(3n-m)(OH)m.Imvelo yayo eguquguqukayo isukela eqinisweni lokuthi ingaba khona ngezindlela ezihlukahlukene kuye ngesilinganiso se-aluminium-to-chloride kanye nezinga le-polymerization.Lokhu kuhlukahluka kuvumela i-PAC ukuthi ikwazi ukuzivumelanisa nezinselele eziningi zokwelashwa kwamanzi.

I-Coagulation kanye ne-Flocculation:

Umsebenzi oyinhloko we-PAC ekwelashweni kwamanzi ukuhlangana nokugeleza kwamanzi.Uma i-PAC yengezwa emanzini aluhlaza, ingena ngaphansi kwe-hydrolysis.Phakathi nale nqubo, yenza i-aluminium hydroxide flocs, ephumelela kakhulu ekubambeni ukungcola okulengiswe emanzini.I-aluminium hydroxide flocs isebenza njengozibuthe abancane, iheha futhi ibophe ndawonye izinhlayiya ezinjengokungcola, amagciwane, nezinto eziphilayo.

Ukususwa Kokungcola:

Indlela ye-PAC ye-coagulation-flocculation isiza ekukhipheni ukungcola okuhlukahlukene emanzini, okuhlanganisa okuqinile okumisiwe, ama-colloid, kanye nezinye izinto ezincibilikisiwe.Njengoba ama-flocs ekhula futhi esindayo, ahlala phansi ethangini lokwelapha ngokusebenzisa i-sedimentation noma abanjwe kalula izihlungi.Lokhu kubangela ukukhiqizwa kwamanzi ahlanzekile nahlanzekile.

Ukungathathi hlangothi kwe-pH:

Enye yezinzuzo eziphawulekayo ze-PAC ukungathathi hlangothi kwayo kwe-pH.Ngokungafani nama-coagulant endabuko afana ne-aluminium sulfate noma i-ferric chloride, engashintsha kakhulu i-pH yamanzi, i-PAC igcina amazinga e-pH azinzile ngokuqhathaniswa.Lokhu kunciphisa isidingo samakhemikhali engeziwe ukulungisa i-pH, ukwenza inqubo yokwelapha ibe lula kanye nokunciphisa izindleko.

Izinzuzo zokusebenzisa i-PAC:

Ukusebenza kahle: I-PAC isebenza ngempumelelo kuwo wonke ama-spectrum abanzi wezimfanelo zamanzi nama-turbidities.

I-Versatility: Ingasetshenziselwa kokubili ukwelashwa kwamanzi okuyisisekelo kanye nasezingeni eliphezulu.

Izinsalela Eziphansi: I-PAC ikhiqiza imikhiqizo embalwa ye-sludge, yehlisa izindleko zokulahla.

Ingabizi kakhulu: Ukusebenza kahle kwayo kanye nokungathathi hlangothi kwe-pH kuyenza ibe ukukhetha okungabizi kakhulu ezitshalweni zokuhlanza amanzi.

Ukuphepha: I-PAC ngokuvamile ibhekwa njengephephile ukuphatha kunamanye ama-coagulant.

Izicelo ze-PAC:

I-PAC ithola ukusetshenziswa okubanzi ezimbonini ezahlukene, okuhlanganisa ukuhlanzwa kwamanzi kamasipala, ukuhlanzwa kwamanzi angcolile ezimbonini, ngisho nasezimbonini zamaphepha nezindwangu.Ikhono layo lokususa ukungcola okuhlukahlukene kuyenza ibe ithuluzi elibalulekile lokuqinisekisa ukutholakala kwamanzi ahlanzekile naphephile.

Sengiphetha, i-Poly Aluminium Chloride (PAC) iyisixazululo esimangalisayo sokwelapha amanzi esisebenza ngokuhlangana nokugeleza.Ukusebenza kwayo, ukuguquguquka, kanye nokungathathi hlangothi kwe-pH kubeke njengento ekhethwayo yezindawo zokuhlanza amanzi emhlabeni jikelele.Njengoba isidingo samanzi ahlanzekile siqhubeka sikhula, i-PAC isalokhu ibambe iqhaza elibalulekile ekuqinisekiseni ukutholakala kwamanzi aphephile naphuzwayo emiphakathini yomhlaba wonke.
