Qhov sib txawv tseem ceeb ntawm fluoridation thiab defluoridation yog fluoridation yog cov txheej txheem ntawm fluoride cov ntsiab lus, whereas defluoridation yog cov txheej txheem ntawm txo cov fluoride cov ntsiab lus nyob rau hauv cov dej haus.
Ob leeg fluoridation thiab defluoridation yog cov txheej txheem tseem ceeb heev txog kev tswj xyuas dej hauv nroog peb siv ua dej haus. Defluoridation yog cov txheej txheem sib txawv ntawm fluoridation, thiab ob qho tib si cov txheej txheem no tuaj yeem pab tau ntau lub sijhawm. Yog li, nws yog ib qho tseem ceeb kom paub qhov txawv qhov txawv ntawm fluoridation thiab defluoridation.
Fluoridation yog dab tsi?
Fluoridation yog txheej txheem ntawm kev nce qib fluoride hauv cov dej haus. Nws yog kev tswj hwm kev hloov kho ntawm cov tshuaj fluoride kom tswj cov qib fluoride tsim nyog hauv dej. Qhov no tseem ceeb heev los tiv thaiv cov hniav lwj. Cov tshuaj fluoride hauv dej tuaj yeem tiv thaiv kev tsim cov kab noj hniav. Hauv cov txheej txheem no, cov tshuaj fluoride ions ntxiv rau cov dej haus. Txawm li cas los xij, fluoridation tsis hloov xim, tsw ntxhiab lossis saj ntawm dej

Yav dhau los, tib neeg siv sodium fluoride rau lub hom phiaj no. Txawm li cas los xij, nws yog ib qho khoom siv tshuaj kim heev. Niaj hnub no, lub teb chaws USA siv rau cov txheej txheem no yog fluorosilicic acid, uas yog pheej yig. Lwm qhov sib xyaw uas peb tuaj yeem siv rau fluoridation yog sodium fluorosilicate.
Defluoridation yog dab tsi?
Defluoridation yog tus txheej txheem ntawm kev txo cov tshuaj fluoride hauv cov dej haus. Hauv dej hauv av, fluoride ion muaj ntau heev. Tsis tas li ntawd, cov ion no muaj nyob hauv cov dej hauv av ntau dua piv rau cov dej saum npoo av. Nws yog vim lub leaching ntawm minerals. Txij li cov ntsiab lus fluoride ion ntau dhau hauv cov dej haus tuaj yeem ua rau muaj teeb meem kev noj qab haus huv sib txawv, defluoridation yog txheej txheem tseem ceeb. Cov teeb meem kev noj qab haus huv uas tshwm sim vim muaj cov tshuaj fluoride siab no suav nrog kev kho hniav fluorosis thiab skeletal fluorosis.

Txawm hais tias muaj ntau cov txheej txheem rau defluoridation, muaj qee qhov kev txwv ib yam. Qhov teeb meem loj yog tus nqi siab. Qee zaum, cov txheej txheem no tuaj yeem tso tawm cov kab mob mus rau dej. Tsis tas li ntawd, cov txheej txheem tseem ceeb uas peb tuaj yeem siv rau defluoridation muaj xws li adsorption, nag lossis daus, ion txauv, txheej txheej membrane, thiab lwm yam. Tag nrho cov txheej txheem no tau zoo heev hauv kev tshem tawm cov fluoride ion, tab sis pov tseg cov fluoride-muaj cov sludge yog teeb meem.
Qhov txawv ntawm Fluoridation thiab Defluoridation yog dab tsi?
Defluoridation yog cov txheej txheem rov qab ntawm fluoridation. Qhov sib txawv tseem ceeb ntawm fluoridation thiab defluoridation yog tias fluoridation yog tus txheej txheem ntawm kev nce cov fluoride cov ntsiab lus, whereas defluoridation yog cov txheej txheem ntawm txo cov fluoride cov ntsiab lus hauv dej haus. Thaum txiav txim siab txog cov txheej txheem ntawm cov txheej txheem no, fluoridation tuaj yeem ua tiav los ntawm kev sib ntxiv ntawm cov tshuaj sib xyaw xws li sodium fluoride, fluorosilicic acid thiab sodium fluorosilicate thiab defluoridation tuaj yeem ua tiav ntawm adsorption, nag lossis daus, ion pauv, txheej txheej membrane, thiab lwm yam.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm fluoridation thiab defluoridation.
Summary – Fluoridation vs Defluoridation
Ob qho tib si fluoridation thiab defluoridation yog cov txheej txheem kho dej tseem ceeb heev. Defluoridation yog cov txheej txheem rov qab ntawm fluoridation. Qhov sib txawv tseem ceeb ntawm fluoridation thiab defluoridation yog tias fluoridation yog tus txheej txheem ntawm kev nce cov fluoride cov ntsiab lus, whereas defluoridation yog tus txheej txheem ntawm txo cov fluoride cov ntsiab lus nyob rau hauv cov dej haus.
