Kodi chimachitika ndi chiyani aluminiyamu sulfate ikakumana ndi madzi?

Aluminiyamu sulfate, yomwe imayimiridwa ndi mankhwala monga Al2(SO4)3, ndi chinthu choyera cha kristalo chomwe chimagwiritsidwa ntchito kwambiri pochiza madzi. Pamene aluminiyamu sulfate imachitapo kanthu ndi madzi, imadutsa mu hydrolysis, njira ya mankhwala yomwe mamolekyu amadzi amagawaniza chinthucho kukhala ma ayoni ake. Njirayi imagwira ntchito yofunika kwambiri pa ntchito zosiyanasiyana, makamaka pakuyeretsa madzi.

Chinthu chachikulu chomwe chimabwera chifukwa cha zimenezi ndi aluminiyamu hydroxyl complex. Chomerachi n'chofunika kwambiri pokonza madzi, chifukwa chimathandiza kuchotsa zinyalala m'madzi. Chomerachi chimakhala ndi mphamvu zambiri, ndipo chikapangidwa, chimakoka ndi kutseka tinthu tomwe timapachikidwa, monga dongo, matope, ndi zinthu zachilengedwe. Zotsatira zake, zinyalala zazing'onozi zimakhala zazikulu komanso zolemera, zomwe zimapangitsa kuti zikhale zosavuta kutuluka m'madzi.

Sulfuric acid yomwe imapangidwa mu reaction imakhalabe mu yankho ndipo imathandizira kuti asidi yonse ya dongosolo ikhalepo. Acidity imatha kusinthidwa momwe ikufunira, kutengera zofunikira za njira yochizira madzi. Kulamulira pH ndikofunikira kuti pakhale bwino njira zolumikizirana ndi flocculation. Kumachepetsanso alkalinity ya madzi. Ngati alkalinity ya madzi a dziwe lokha ndi yochepa, ndiye kuti NaHCO3 iyenera kuwonjezeredwa kuti iwonjezere alkalinity ya madzi.

Kuchitapo kanthu pakati pa aluminiyamu sulfate ndi madzi nthawi zambiri kumagwiritsidwa ntchito pomanga ndi kusuntha kwa madzi m'malo oyeretsera madzi. Kumanga kumaphatikizapo kusokoneza tinthu tomwe timapachikidwa, pomwe kusuntha kumalimbikitsa kusonkhanitsa tinthuti kukhala tinthu tating'onoting'ono tomwe timakhala tosavuta kukhazikika. Njira zonsezi ndizofunikira kwambiri pochotsa zonyansa komanso kuyeretsa madzi.

Ndikofunika kudziwa kuti kugwiritsa ntchito aluminiyamu sulfate poyeretsa madzi kwadzetsa nkhawa zachilengedwe chifukwa cha kuchuluka kwa aluminiyamu m'madzi am'madzi. Kuti tichepetse nkhawazi, kuyeza ndi kuyang'anira bwino ndikofunikira kuti zitsimikizire kuti kuchuluka kwa aluminiyamu m'madzi oyeretsedwa kukutsatira miyezo yoyenera.

Pomaliza, aluminiyamu sulfate ikakumana ndi madzi, imadutsa mu hydrolysis, ndikupanga aluminiyamu hydroxide ndi sulfuric acid. Mankhwalawa ndi ofunikira kwambiri pa njira zochizira madzi, pomwe aluminiyamu hydroxide imagwira ntchito ngati coagulant yochotsa zinyalala zomwe zatsala m'madzi. Kuwongolera ndi kuyang'anira koyenera ndikofunikira kuti madzi ayeretsedwe bwino komanso kuchepetsa kuwonongeka kwa chilengedwe.
