Kwenzeka ntoni xa i-aluminium sulfate idibana namanzi?

I-aluminium sulfate, emele ngokwekhemikhali njenge-Al2(SO4)3, yikristale emhlophe eqinileyo esetyenziswa kakhulu kwiinkqubo zokunyanga amanzi. Xa i-aluminium sulfate isabela namanzi, idlula kwi-hydrolysis, i-chemical reaction apho iimolekyuli zamanzi zahlula i-compound zibe yi-ions zayo. Le reaction idlala indima ebalulekileyo kwiindlela ezahlukeneyo zokusebenza, ngakumbi ekucoceni amanzi.

Imveliso ephambili yale reaction yi-aluminium hydroxyl complex. Le complex ibalulekile ekunyangweni kwamanzi, njengoko inceda ekususeni ukungcola emanzini. I-aluminium hydroxyl complex inobunzima obukhulu bokutshaja, kwaye xa yenziwe, ithambekele ekubambeni nasekujijeni amasuntswana axhonyiweyo, njengodongwe, i-silt, kunye nezinto eziphilayo. Ngenxa yoko, la masuntswana mancinci aba makhulu kwaye abe nzima, okwenza kube lula ukuba ahlale emanzini.

I-asidi yesulfuric eveliswa kwi-reaction ihlala kwisisombululo kwaye inegalelo kwi-asidi iyonke yenkqubo. I-asidi ingalungiswa njengoko kufuneka, kuxhomekeke kwiimfuno ezithile zenkqubo yokunyanga amanzi. Ukulawula i-pH kubalulekile ukuze kuphuculwe ukusebenza kakuhle kweenkqubo zokujiya kunye ne-flocculation. Ikwanciphisa i-alkalinity yamanzi. Ukuba i-alkalinity yamanzi echibini ngokwayo iphantsi, kufuneka kongezwe i-NaHCO3 ukuze kwandiswe i-alkalinity yamanzi.

Indlela esebenza ngayo i-aluminium sulfate namanzi idla ngokusetyenziswa kumanyathelo okuxinana nokuqunjelwa kwezityalo zokunyanga amanzi. Ukuxinana kwamanzi kubandakanya ukungazinzi kwee-particles ezixhonyiweyo, ngelixa ukuqunjelwa kwamanzi kukhuthaza ukuhlanganiswa kwezi -particles zibe zii-flocs ezinkulu nezilula ukuzinza. Zombini ezi nkqubo zibalulekile ekususweni kokungcola kunye nokucaciswa kwamanzi.

Kubalulekile ukuqaphela ukuba ukusetyenziswa kwe-aluminium sulfate ekunyangweni kwamanzi kuphakamise iinkxalabo zokusingqongileyo ngenxa yokuqokelelwa kwe-aluminium kwiindawo eziphilayo zasemanzini. Ukunciphisa ezi nkxalabo, ukulinganisa ngokuchanekileyo kunye nokubeka esweni kubalulekile ukuqinisekisa ukuba ubuninzi be-aluminium emanzini anyangiweyo buhlangabezana nemigangatho emiselweyo.

Ukuqukumbela, xa i-aluminium sulfate idibana namanzi, ingena kwi-hydrolysis, ivelise i-aluminium hydroxide kunye ne-sulfuric acid. Le khemikhali ibalulekile kwiinkqubo zonyango lwamanzi, apho i-aluminium hydroxide isebenza njenge-coagulant ukususa ukungcola okuxhonyiweyo emanzini. Ulawulo olufanelekileyo kunye nokubeka iliso kuyimfuneko ukuqinisekisa ukucocwa kwamanzi ngempumelelo ngelixa kunciphisa impembelelo yokusingqongileyo.
