Fluoride muaj qee yam cuam tshuam rau kev noj qab haus huv. Thaum haus cov dej uas muaj cov tshuaj fluoride ntau dhau lawm, kev noj cov tshuaj fluoride ntau dhau tuaj yeem ua rau mob fluorosis, hniav fluorosis, skeletal fluorosis, thiab lwm yam. Kev haus dej yog txoj hauv kev tseem ceeb kom nqus tau cov tshuaj fluoride. Yog li, cov qauv kev huv huv rau cov dej haus tau teev tseg tias cov ntsiab lus fluoride hauv cov dej haus yuav tsum tsis pub tshaj 1.0 mg/L.
Ua kom muaj aluminasiv rau kev tshem tawm cov tshuaj fluoride yog lub pob dawb adsorbent nrog thaj chaw loj. Activated alumina muaj cov tshuaj fluoride tshem tawm zoo thiab ua haujlwm zoo. 1 gram ntawm activated alumina tuaj yeem nqus tau 2.5-3mg ntawm fluoride. Feem ntau siv yog 2-3mm, 3-5mm, thiab 4-6mm.
Cov nyhuv adsorption muaj feem xyuam rau cov fluorine concentration ntawm cov dej nyoos, pH nqi, particle loj, ntau, sijhawm thiab lwm yam.
