Kodi chimachitika ndi chiyani pamene aluminium sulphate imachita ndi madzi?

Aluminium sulphate, mankhwala akuimiridwa monga Al2 (SO4) 3, ndi woyera crystalline olimba kuti ambiri ntchito njira mankhwala madzi.Aluminiyamu sulphate ikakumana ndi madzi, imalowa mu hydrolysis, momwe mamolekyu amadzi amagawanitsa gawolo kukhala ayoni ake.Zimenezi zimathandiza kwambiri pa ntchito zosiyanasiyana, makamaka poyeretsa madzi.

Chofunikira chachikulu cha izi ndi aluminium hydroxyl complex.Vutoli ndi lofunika kwambiri poyeretsa madzi, chifukwa limathandizira kuchotsa zonyansa m'madzi.Aluminium hydroxyl complex ili ndi kachulukidwe kwambiri, ndipo ikapangidwa, imatchera msampha ndikumangirira tinthu ting'onoting'ono, monga dongo, silt, ndi zinthu zachilengedwe.Zotsatira zake, zonyansa zazing'onozi zimakhala zazikulu komanso zolemera kwambiri, zomwe zimapangitsa kuti zikhale zosavuta kuti zikhazikike m'madzi.

The sulfuric acid opangidwa mmenemo amakhalabe yankho ndi kumathandiza kuti asidi wonse wa dongosolo.Acidity ikhoza kusinthidwa ngati ikufunika, malingana ndi zofunikira zenizeni za njira yopangira madzi.Kuwongolera pH ndikofunikira pakuwongolera bwino kwa ma coagulation ndi ma flocculation.Zimachepetsanso mchere wamadzi.Ngati alkalinity ya madzi a dziwe palokha ndi yochepa, ndiye kuti NaHCO3 iyenera kuwonjezeredwa kuti iwonjezere mchere wa madzi.

Zomwe zimachitika pakati pa aluminiyamu sulphate ndi madzi zimagwiritsidwa ntchito popanga ma coagulation ndi ma flocculation a malo opangira madzi.Coagulation kumafuna destabilization ya inaimitsidwa particles, pamene flocculation amalimbikitsa aggregation awa particles mu zikuluzikulu, mosavuta settleable flocs.Njira zonsezi ndi zofunika kwambiri pakuchotsa zonyansa komanso kumveketsa bwino madzi.

Ndikofunikira kudziwa kuti kugwiritsa ntchito aluminium sulphate poyeretsa madzi kwadzetsa nkhawa zachilengedwe chifukwa cha kuchuluka kwa aluminiyumu m'zamoyo zam'madzi.Kuti muchepetse nkhawazi, kuwunika moyenera ndi kuyang'anira ndikofunikira kuwonetsetsa kuti kuchuluka kwa aluminiyamu m'madzi oyeretsedwa kumakwaniritsa zofunikira.

Pomaliza, pamene aluminiyamu sulphate amakumana ndi madzi, imalowa hydrolysis, kupanga aluminium hydroxide ndi sulfuric acid.Mankhwalawa amaphatikizidwa ndi njira zochizira madzi, pomwe aluminium hydroxide imakhala ngati coagulant kuchotsa zonyansa zomwe zayimitsidwa m'madzi.Kuwongolera ndi kuyang'anira koyenera ndikofunikira kuti madzi ayeretsedwe bwino ndikuchepetsa kuwononga chilengedwe.
