Ezweni elibhekene nokwanda kokungcoliswa kwamanzi kanye nokuntuleka kwawo, izixazululo ezintsha zibalulekile ukuqinisekisa amanzi ahlanzekile naphephile kubo bonke. Esinye sezixazululo ezinjalo esiye sathola ukunakwa okukhulu yilesiI-Poly Aluminium Chloride(PAC), ikhemikhali eguquguqukayo eguqula isimo sokwelashwa kwamanzi.
Amanzi, umthombo onqunyelwe, ahlala esongelwa ngenxa yokungcola okuhlukahlukene kanye nokungcola. Izimboni, intuthuko yasemadolobheni, kanye nemisebenzi yezolimo kuholele ekukhishweni kwezinto eziyingozi emanzini, okubeka ingozi enkulu kokubili emvelweni kanye nempilo yabantu. Izindlela zokwelapha amanzi ezivamile ziyazabalaza ukubhekana nobunzima obandayo balezi zinto ezingcolisayo. Yilapho i-PAC ingena khona, inikeza indlela ephumelela kakhudlwana futhi eqhubekayo yokuhlanza amanzi.
Kuyini i-Poly Aluminium Chloride?
I-Poly Aluminium Chloride, evame ukufushaniswa ngokuthi i-PAC, iyi-coagulant yamakhemikhali evame ukusetshenziswa ezinqubweni zokwelashwa kwamanzi. Itholakala ku-aluminium chloride ngokusabela ne-hydroxide, i-sulfate, noma amanye ama-salts. I-PAC yaziwa ngekhono layo lokususa izinto eziqinile ezilengayo, izinto eziphilayo, nokunye ukungcola emanzini, okwenza kube ukukhetha okuhle kwezicelo ezahlukene zokuhlanza.
Isebenza Kanjani i-PAC?
I-PAC isebenza njenge-coagulant kanye ne-flocculant ekuhlanzweni kwamanzi. Uma ifakwe emanzini, yakha amaketanga e-polymer ashajelwe kahle aqeda izinhlayiya ezishajelwe kabi njengokungcola, ukungcola, kanye nama-microorganism. Lezi zinhlayiya ezingasebenzi bese zihlangana zibe izinhlayiya ezinkulu ezibizwa ngokuthi ama-floc. Lezi zinhlayiya zihlala phansi, zivumela amanzi acwebile ukuthi ahlukaniswe ne-sediment. Le nqubo iphumelela kakhulu ekususeni uhla olubanzi lwezinto ezingcolisayo, okuhlanganisa izinsimbi ezisindayo, amabhaktheriya, kanye nama-organic compounds.
Izinzuzo Zokusebenzisa i-PAC:
Ukusebenza kahle: I-PAC inikeza ukujiya okusheshayo kanye nokugoba, okuholela ekuhlanzweni okusheshayo uma kuqhathaniswa nezindlela zendabuko.
Ukuguquguquka: Ingasetshenziswa emithonjeni ehlukahlukene yamanzi, okuhlanganisa ukwelashwa kwamanzi okuphuza, ukwelashwa kwamanzi angcolile, izinqubo zezimboni, nokuningi.
Ukukhiqizwa Kodaka Okuncishisiwe: I-PAC ikhiqiza udaka oluncane uma kuqhathaniswa nezinye izinto ezihlanganisa ukungcola, okunciphisa izindleko zokulahla kanye nomthelela emvelweni.
Ukubekezelela i-pH: Kusebenza kahle kulo lonke uhla lwe-pH olubanzi, kuhlinzeka ngemiphumela efanayo ezimweni ezahlukene zamanzi.
Ukusebenza Kahle Kwezindleko: Ukusebenza kahle kwe-PAC, kuhlanganiswe nezidingo zayo zomthamo ophansi, kungaholela ekongeni izindleko ezinqubweni zokwelapha.
Ukusimama kanye nomthelela kwezemvelo:
Enye yezinzuzo ezibalulekile ze-PAC ukuthi inomthelela ophansi kakhulu kwezemvelo uma kuqhathaniswa nezinye izinto ezihlanganisa ukungcola. Ukususwa kwayo okusebenzayo kokungcola kunciphisa isidingo sokusetshenziswa kakhulu kwamakhemikhali. Ngaphezu kwalokho, ukukhiqizwa kwayo kodaka okuncishisiwe kunegalelo ekunciphiseni ukukhiqizwa kwemfucuza.
Njengoba umhlaba ufuna izixazululo eziqhubekayo zokwelashwa kwamanzi, i-PAC ikulungele ukudlala indima ebalulekile. Ukuzivumelanisa nezimo kwayo, ukusebenza kahle kwayo, kanye nezinzuzo zemvelo kuyenza ibe yilungu elithembisayo lokubhekana nezinselele zekhwalithi yamanzi ezibhekene nemiphakathi namuhla.
Ekuphetheni, i-Poly Aluminium Chloride (PAC) iyavela njengoshintsho olukhulu emkhakheni wokwelashwa kwamanzi. Njengoba ikwazi ukususa ukungcola ngempumelelo, ukunciphisa ukukhiqizwa kodaka, nokusebenza emazingeni ahlukahlukene e-pH, i-PAC inikeza ikhambi eliqinile neliqhubekayo ezinkingeni ezikhulayo zokungcoliswa kwamanzi. Njengoba imiphakathi kanye nezimboni ziqhubeka nokubeka phambili amanzi ahlanzekile, indima ye-PAC ekuqinisekiseni ikusasa elihlanzekile izokhula, okuwuphawu lwesinyathelo esibalulekile ekuphepheni kwamanzi emhlabeni jikelele.
Ukuze uthole imibuzo kanye nolwazi olwengeziwe, sicela uxhumane nathi:
