1. Ukwenzakala kwamanzi aqinileyo kwindawo yokuhlamba impahla
Ubunzima bamanzi bubhekisela kumxholo weetyuwa ezichithwe emanzini, oko kukuthi, umxholo weetyuwa ze-calcium kunye neetyuwa ze-magnesium.Okuphezulu umxholo, ukuphakama kobunzima, ngokuphambene.I-GPG yiyunithi yobunzima bamanzi, i-1GPG ithetha ukuba umxholo we-ion yobunzima (i-calcium kunye ne-magnesium ions) kwi-1 galoni yamanzi yi-1 ingqolowa.
Umgangatho wamanzi aqinileyo:
Ngokomgangatho we-American WQA (uMbutho woMgangatho waManzi), ubunzima bamanzi buhlukaniswe ngamanqanaba angama-6.I-0 - 0.5GPG ngamanzi athambileyo, i-0.5 - 3.5GPG inzima kancinci, i-3.5 - 7.0GPG inzima kakhulu, i-7.0 - 10.5GPG ngamanzi anzima, i-10.5 - 14.0GPG inzima kakhulu, kwaye ngaphezu kwe-14.0GPG inzima kakhulu.
Amanzi aqinileyo okuhlamba impahla anokuba nemiphumo engathandekiyo.I-calcium kunye ne-magnesium ion emanzini anzima afakwe kwilaphu, ebangela ukuba amalaphu amhlophe abe ngwevu.Kuya kuchaphazela ubumhlophe kunye nokuziva, kwaye wenze umbala welaphu uphele kwaye ulahlekelwe bubuhle bayo.Ngaphezu koko, i-calcium kunye ne-magnesium ion zifakwe kwilaphu, kwaye ukunamathela kwifiber yomelele kakhulu.Kunzima kakhulu ukuhlamba i-calcium kunye ne-magnesium ion enamathela kwilaphu kwaye wenze ilaphu elingwevu libe mhlophe.Eyona ndlela ilungileyo yokuhlamba amalaphu amhlophe kumanzi aqinileyo angabikho okanye abe ngwevu kukuthatha amanyathelo okhuseleko kuqala.
Intsimbi ayikho emanzini njengesinyithi, kodwa njenge-ion okanye i-ionic compound.Ukuba olu hlobo lwamanzi lufudunyezwa ukuhlamba amalaphu, umhlwa (i-iron hydroxide) iya kwenziwa kwaye ifakwe kwilaphu njengamabala athile amdaka.Kuya kwenza amalaphu amhlophe ajike amthubi ngokupheleleyo kwaye enze amalaphu anemibala aphele.Ukususa ezi zikali zentsimbi, unyango olukhethekileyo nge-asidi lufunekayo.Enye ingozi yentsimbi emanzini kukuba inefuthe elithile elibangela ukubola kwe-hypochlorite kunye ne-hydrogen peroxide.Kwinqanaba le-bleaching, ukuba i-ion ye-iron ikhona kwindawo ethile yelaphu, iya kubangela ukubola okunamandla kwe-hypochlorite okanye i-hydrogen peroxide, eya kwenza impendulo ye-oxidation yendawo ibe nobundlobongela kwaye ikhokelele kumonakalo welaphu.
2. Iimfuno zamanzi okuhlamba
Amanzi oselaimigangatho yomgangatho, ezinye izikhombisi zeekhemikhali zimi ngolu hlobo lulandelayo:
Ixabiso le-PH: 6.5 - 8.5
Ubunzima bubonke: ≤446ppm
Intsimbi: ≤0.3mg/L
IManganese: ≤0.1mg/L.
Amanzi okuhlambaiimfuno:
PH ixabiso: 6.5~7
Ubunzima bubonke: ≤25ppm (ngokukhethekileyo 0)
Intsimbi: ≤0.1mg/L
IManganese: ≤0.05mg/L
Amanzi etephu asetyenziswa ngokubanzi kwisebe lokuhlamba impahla kwiihotele zasezidolophini.Amanzi etephu aveliswa ngokomgangatho wokusetyenziswa kwamanzi ezindlini, kwaye akukho ngxaki xa abantu bewasela.Kodwa njengamanzi okuhlamba, ngokucacileyo ayifanelekanga.Ngoko ke, ukuze kufezekiswe iimfuno zokuhlamba ezisemgangathweni, amanzi okuhlamba kufuneka aphathwe kwinqanaba elithile.
