Njengesitsha sokuphuza esivamile, izinkomishi zamanzi zensimbi engagqwali zithandwa kakhulu ngenxa yokuqina kwazo, ukuhlanzeka kalula, kanye nezindawo zokulwa namagciwane. Nokho, ngezinye izikhathi sithola amachashaza okugqwala phezu kwezinkomishi zamanzi zensimbi engagqwali, okuphakamisa umbuzo: Kungani izinkomishi zamanzi zensimbi engagqwali zigqwala kalula? Lo mbuzo uhilela izici zensimbi engagqwali nezici zokusetshenziswa nokugcinwa. Lesi sihloko sizochaza izizathu zalesi simo kusuka ezicini eziningana.
Okokuqala, insimbi engagqwali ayiyona into engagqwali ngokuphelele. Ukumelana nokugqwala kwensimbi engagqwali ngokuyinhloko kuvela entweni ye-chromium ekuyo, esabela nomoya-mpilo ukuze yakhe ifilimu eminyene ye-chromium oxide, ngaleyo ndlela ivimbele ukuqhubekela phambili kwe-oxidation yensimbi. Kodwa-ke, le filimu ye-chromium oxide ayiphelele futhi ingase yonakaliswe izici zangaphandle, okubangele ukuthi indawo yensimbi ivezwe emoyeni. Lapho ifilimu ye-chromium oxide ebusweni benkomishi yamanzi ilimele, insimbi izoqala ukusabela nge-oxidation futhi yakhe izindawo zokugqwala.
Okwesibili, ukugqwala kwezinkomishi zamanzi zensimbi engagqwali kungase kuhlotshaniswe nokusetshenziswa nokugcinwa ngendlela engafanele. Ngesikhathi sokusetshenziswa, uma ibhodlela lamanzi lensimbi engagqwali lidliwe yizixazululo ezine-acidic noma i-alkaline, noma livezwa emanzini anosawoti isikhathi eside, ifilimu ye-chromium oxide endaweni yensimbi izolimala. Ngaphezu kwalokho, uma usebenzisa amathuluzi okuhlanza amabi ukukhuhla inkomishi yamanzi, kungase futhi kulimaze ifilimu ye-chromium oxide, kubangele ukuthi inkomishi yamanzi igqwale. Ngakho-ke, ukusebenzisa ngendlela efanele kanye nezindlela zokunakekela kubalulekile ekwandiseni impilo yesevisi yamabhodlela amanzi ensimbi engagqwali.
Okwesithathu, ukugqwala kwenkomishi yamanzi kungase futhi kuhlobane nekhwalithi yamanzi. Amanzi kampompi kwezinye izindawo angase abe namazinga aphezulu e-iron noma amanye ama-ion ensimbi. Lawa ma-ion ensimbi angase asabele ngamakhemikhali nensimbi lapho ethintana nendawo engaphezulu yenkomishi yamanzi yensimbi engagqwali isikhathi eside, okwenza inkomishi yamanzi igxume. Uma izinga lamanzi endaweni yangakini lingelihle, cabanga ukusebenzisa isisefo noma ukuthenga amanzi okuphuza ahlanzwe ukuze kwehliswe ukugqwala ezingilazini zokuphuza zensimbi engagqwali.
Okokugcina, ukuthenga ibhodlela lamanzi lensimbi engagqwali elisezingeni elihle kunganciphisa amathuba okugqwala. Kunamabhodlela amanzi ensimbi engagqwali ahlukahlukene emakethe, anekhwalithi ehlukahlukene. Amabhodlela amanzi ensimbi engenasici esezingeni eliphezulu ngokuvamile enziwa ngensimbi engagqwali yekhwalithi ephezulu futhi athola ukwelashwa okukhethekile ukuze enze ifilimu ye-chromium oxide ibe namandla futhi iqine, ngaleyo ndlela kuncishiswe ubungozi bokugqwala.
Ukufingqa, nakuba amabhodlela amanzi ensimbi engagqwali ekwazi ukumelana nokugqwala, awavikelekile ekugqwaleni. Izinto ezinjengokusetshenziswa nokugcinwa ngendlela engafanele, izinkinga zekhwalithi yamanzi, nekhwalithi yezinto ezibonakalayo kungase kubangele ukugqwala kwezinkomishi zamanzi zensimbi engagqwali. Ngakho-ke, ukusetshenziswa okulungile, ukuhlanza nokugcinwa njalo, nokukhetha amabhodlela amanzi ensimbi engagqwali asezingeni eliphezulu konke kuyizihluthulelo zokunciphisa ingozi yokugqwala. Ngokusetshenziswa nokugcinwa okufanele kuphela singajabulela ukunethezeka nempilo elethwa amabhodlela amanzi ensimbi engagqwali.
