Kwenzeka ntoni xa i-aluminiyam sulphate idibana namanzi?

I-aluminium sulfate, ikhemikhali emelwe njenge-Al2 (SO4) 3, i-crystalline solidified eqinile esetyenziswa ngokuqhelekileyo kwiinkqubo zokunyanga amanzi.Xa i-aluminiyam sulfate idibana namanzi, ingena kwi-hydrolysis, intshukumo yekhemikhali apho iimolekyuli zamanzi zahlulahlula ikhompawundi ibe yi-ion yayo.Oku kusabela kudlala indima ebalulekileyo kwizicelo ezahlukeneyo, ngakumbi ekucoceni amanzi.

Imveliso yokuqala yale mpendulo yi-aluminiyam hydroxyl complex.Le nto inzima ibalulekile kunyango lwamanzi, njengoko inceda ekukhupheni ukungcola emanzini.I-aluminiyam hydroxyl complex inoxinano lwentlawulo ephezulu, kwaye xa yenziwe, ithande ukurhintyela kwaye ijike amasuntswana amisiweyo, afana nodongwe, intlenga, kunye nezinto eziphilayo.Ngenxa yoko, obu kungcola buncinci buba ngamasuntswana amakhulu kwaye bunzima, nto leyo eyenza kube lula ukuba bazinze ngaphandle kwamanzi.

I-asidi ye-sulfuric eveliswa kwi-reaction ihlala kwisisombululo kwaye igalelo kwi-asidi iyonke yenkqubo.I-asidi inokulungelelaniswa njengoko kufuneka, kuxhomekeke kwiimfuno ezithile zenkqubo yokucoca amanzi.Ukulawula i-pH kubalulekile ekuphuculeni ukusebenza kakuhle kwe-coagulation kunye neenkqubo ze-flocculation.Kwakhona kunciphisa i-alkalinity yamanzi.Ukuba i-alkalinity yamanzi echibini ngokwayo iphantsi, ngoko ke i-NaHCO3 idinga ukongeza ukunyusa i-alkalinity yamanzi.

Ukusabela phakathi kwe-aluminiyam sulfate kunye namanzi idla ngokusetyenziswa kwi-coagulation kunye ne-flocculation amanyathelo okucoca amanzi.I-Coagulation ibandakanya ukuchithwa kweengqungquthela ezimisiweyo, ngelixa i-flocculation ikhuthaza ukuhlanganiswa kwezi ngqungquthela zibe zinkulu, ezizinzile ngokulula.Zombini ezi nkqubo zibalulekile ekususeni ukungcola kunye nokucaciswa kwamanzi.

Kubalulekile ukuqaphela ukuba ukusetyenziswa kwe-aluminium sulfate kunyango lwamanzi kuye kwaphakamisa inkxalabo yokusingqongileyo ngenxa yokuqokelela okunokwenzeka kwe-aluminiyam kwi-ecosystems yasemanzini.Ukunciphisa ezi nkxalabo, ukudosa okuchanekileyo kunye nokubeka iliso kubalulekile ukuqinisekisa ukuba ugxininiso lwe-aluminiyam kumanzi acociweyo luyahlangabezana nemigangatho yolawulo.

Ekugqibeleni, xa i-aluminium sulfate iphendula ngamanzi, idlula i-hydrolysis, ivelise i-aluminium hydroxide kunye ne-sulfuric acid.Le mpendulo yeekhemikhali ibalulekile kwiinkqubo zokunyanga amanzi, apho i-aluminium hydroxide isebenza njenge-coagulant ukususa ukungcola okumisiwe emanzini.Ulawulo olululo kunye nokubeka iliso kuyimfuneko ukuze kuqinisekiswe ukucocwa kwamanzi okusebenzayo ngelixa kuncitshiswa impembelelo yokusingqongileyo.
