Kuhlala kukho ukungcola okuninzi kumanzi endalo, phakathi kwazo ezona ziphambili ezichaphazela ibhoyila zezi: into emisiweyo, icolloidal matter kunye nenyibilikisiwe.
1. Izinto ezimisiweyo kunye nezinto eziqhelekileyo zenziwe ngentlenga, izidumbu zezilwanyana kunye nezityalo, kunye nezinye i-low-molecular aggregates, ezona zinto ziphambili ezenza amanzi aqhube.Xa ezi zinto zingcolileyo zingena kwi-ion exchanger, ziya kungcolisa i-resin yokutshintshiselana kwaye zichaphazele umgangatho wamanzi.Ukuba bangena kwibhoyila ngokuthe ngqo, umgangatho womphunga uya kuwohloka ngokulula, uqokelele eludakeni, uvale imibhobho, kwaye ubangele ukuba isinyithi sitshise kakhulu.
2. Izinto ezinyityilisiweyo zibhekisa ikakhulu kwiityuwa kunye nezinye iigesi ezinyityilisiweyo emanzini.Amanzi endalo, amanzi ompompo ajongeka ecocekile kakhulu aneetyuwa ezahlukeneyo ezinyityilisiweyo, kubandakanya icalcium, imagnesium, kunye netyuwa.Izinto ezinzima zingunobangela oyintloko wokungcoliswa kwebhoyila.Kuba isikali siyingozi kakhulu kwiibhoyila, ukususa ubulukhuni kunye nokuthintela isikali ngumsebenzi ophambili wokucocwa kwamanzi kwibhoyila, onokuthi uphunyezwe ngonyango lwekhemikhali ngaphandle kwebhoyila okanye unyango lwekhemikhali ngaphakathi kwibhoyila.
3. I-oksijeni kunye ne-carbon dioxide ichaphazela kakhulu izixhobo zebhoyili yegesi yegesi kwi-gas enyibilikileyo, ebangela i-oxygen corrosion kunye ne-acid corrosion kwibhoyili.Ioksijini kunye ne-hydrogen ion zisasebenza ngakumbi kwi-depolarizers, ekhawulezisa ukubola kwe-electrochemical.Yenye yezinto ezibalulekileyo ezibangela ukubola kwebhoyila.Ioksijini enyibilikisiweyo inokususwa yi-deaerator okanye yongeza iziyobisi zokunciphisa.Kwimeko ye-carbon dioxide, ukugcina i-pH ethile kunye ne-alkalinity yamanzi embizeni inokuphelisa umphumo wayo.
