Uma ukhetha indawo efanele yangaphandleithreyi yekhebula, kunezinto ezimbili ezivamile ezivame ukucatshangelwa: ithreyi yekhebula eligoqekile elishisayo kanye nethreyi yekhebula lensimbi engagqwali. Into ngayinye inezakhiwo zayo ezihlukile, izinzuzo kanye nokungalungi, futhi ifanelekela izindawo ezahlukene kanye nezinhlelo zokusebenza.
Amathreyi ekhebula acwebezelayo ashisayozenziwe ngensimbi embozwe kusetshenziswa inqubo yokugaya i-hot dip. Lokhu kugqoka kunikeza ukumelana okuhle kakhulu nokugqwala, okwenza kube kuhle kakhulu ukusetshenziswa ngaphandle lapho kudingeka khona ukusingatha umswakama kanye nezimo zezulu ezimbi. Ingqimba ye-zinc isebenza njenge-anode yokuzidela, ivikela insimbi engaphansi ekugqwaleni nasekuwohlokeni. Ngaphezu kwalokho, amathreyi ekhebula eligoqiwe le-hot dip avame ukuba ngcono kakhulu kunethreyi lekhebula lensimbi engagqwali, okwenza kube ukukhetha okuthandwayo kumaphrojekthi amakhulu.
Ngakolunye uhlangothi, amathreyi ekhebula lensimbi engagqwali anikeza ukuqina okuphezulu kanye nokumelana nokugqwala, ikakhulukazi ezindaweni lapho ukuchayeka kumakhemikhali noma usawoti kungenzeka khona. Insimbi engagqwali ngokwemvelo imelana nokugqwala futhi ingamelana namazinga okushisa aphezulu, okwenza kube ukukhetha okuhle kakhulu kwezimboni ezifana nezasolwandle, ukucubungula amakhemikhali, kanye nokukhiqizwa kokudla. Ngenkathi amathreyi ekhebula lensimbi engagqwali evame ukubiza kakhulu kunamathreyi ekhebula ashisiwe, impilo yawo ende kanye nokugcinwa kwayo okuphansi kuyenza ifanele ukutshalwa kwezimali kusengaphambili.
Ngamafuphi, ukukhetha phakathi kokucwilisa okushisayo kanyeamathreyi ekhebula lensimbi engagqwalikuncike kakhulu ezimweni ezithile zemvelo kanye nemikhawulo yesabelomali yephrojekthi. Ngezicelo ezijwayelekile zangaphandle lapho izindleko ziyisici esibalulekile, amathreyi ekhebula afakwe ngogesi ashisayo angaba yisinqumo esingcono kakhulu. Kodwa-ke, ezindaweni ezidinga ukumelana nokugqwala okuphezulu nokuqina, amathreyi ekhebula lensimbi engagqwali ayisinqumo esingcono kakhulu. Ekugcineni, ukuqonda izakhiwo ezihlukile zezinto ngayinye kuzosiza ekwenzeni isinqumo esinolwazi ukuqinisekisa ukuhlala isikhathi eside nokuthembeka kohlelo lokuphatha ikhebula.
