Kungani I-Polyaluminium Chloride Ingasusa I-Fluoride?

I-Fluoride iyiminerali enobuthi. Ivame ukutholakala emanzini okuphuza. Izinga lamanje lamanzi okuphuza lamazwe ngamazwe le-fluoride elibekwe yi-World Health Organization (WHO) lingu-1.5 ppm. Amazinga aphezulu e-fluoride angabangela i-fluorosis yamazinyo ne-skeletal, ngakho-ke i-fluoride eyengeziwe kufanele ikhishwe emanzini okuphuza. Phakathi kwezinhlobonhloboamakhemikhali okwelapha amanzietholakalayo, i-polyaluminium chloride (PAC) iyinketho yokuqala yokukhishwa kwe-fluoride. Ikhono le-PAC lokususa i-fluoride lisukela kumakhemikhali ayo ahlukile kanye nendlela yokusebenza. Ake sihlole indlela yayo, izinzuzo kanye nezicelo.

Indlela yokusebenza ye-polyaluminium chloride:

I-Polyaluminium chlorideiyi-coagulant ye-inorganic ekhiqizwa ukusabela kwe-aluminium hydroxide ne-hydrochloric acid. Ivame ukusetshenziswa njenge-flocculant ezinqubweni zokuhlanza amanzi kamasipala nezimboni.

I-Polyaluminium chloride i-electrostatic adsorb futhi ihlanganiswe nama-ion e-fluoride ukuze yakhe izinhlobonhlobo zezimo ezinzile. Lokhu kube sekuphinde kwakha futhi kudonse i-aluminium fluoride engancibiliki.

Ama-ion e-aluminium nama-fluoride ions nawo angakha izinhlobonhlobo zezimo ezinzile (ezifana nokunciphisa ukugcwala kwe-fluoride yamahhala emanzini.

Izinzuzo ze-PAC njenge-defluoridant

Ukusebenza kahle okuphezulu: I-PAC ingafinyelela amazinga abalulekile okususwa kwe-fluoride, ngokuvamile edlula ama-90% ngaphansi kwezimo ezifanele. Uma kuqhathaniswa nosawoti we-aluminium wendabuko, i-PAC inomthamo wokushaja ophakeme kanye nezinga le-flocculation elisheshayo. Ukusebenza kahle kwe-defluoridation kukhuphuka ngo-30% kumthamo ofanayo.

Ezomnotho: Izindleko zokwelashwa zehliswa ngaphezu kuka-40% uma kuqhathaniswa nobuchwepheshe obufana ne-reverse osmosis, futhi akukho mishini eyinkimbinkimbi edingekayo.

Futhi ububanzi bokusebenzisa i-pH bubanzi (5.0-9.0). Futhi imfucumfucu yamanzi ingancishiswa kanyekanye.

Ukukhiqizwa kodaka oluphansi: Udaka oluncane luyakhiwa, okulula ukuluphatha.

Amanothi nge-PAC njenge-defluoridant:

I-PAC isebenza kahle kakhulu kumanani e-pH ane-acidic kancane ukuya kokungathathi hlangothi (cishe u-6.5 kuya ku-7.5). Ukugcina inani le-pH elifanele kuqinisekisa ukukhishwa okuphezulu kwe-fluoride.

Ukususwa kwe-fluoride kuncike ekugxilweni kwe-fluoride kokuqala kanye nomthamo we-coagulant.

Ukusetshenziswa kwe-PAC ku-Fluoride Ukususwa

Ukwelashwa kwamanzi kamasipala: Qinisekisa ukuphepha kwamanzi okuphuza ngokunciphisa i-fluoride ibe emazingeni amukelekayo.

Ukwelashwa kwamanzi angcolile ezimbonini: Khipha i-fluoride emanzini angcolile akhiqizwa izimboni ezifana nokukhiqiza ingilazi, ukukhiqizwa kwe-semiconductor kanye nezitshalo zikamanyolo.

Ukubuyiselwa kwemvelo: Phatha amanzi angaphansi komhlaba kanye nomhlabathi ongcoliswe i-fluoride yemvelo ukuze uvikele indawo ezungezile.

Ukubuyiselwa kwezolimo nemvelo: Khipha ama-ion e-Fluoride emanzini okunisela ukuze ugweme ukucwiliswa kukasawoti enhlabathini kanye nokulimala kwezitshalo.

I-Polyaluminium chloride iyisixazululo esifakazelwe nesisebenzayo sokususwa kwe-fluoride ekusetshenzisweni kokwelashwa kwamanzi. Ikhono layo lokujiya kanye ne-adsorb fluoride ions liyenza ibe yinketho yokuqala ezindaweni zikamasipala nezimboni. Kubaluleke kakhulu ukukhetha umphakeli wamakhemikhali onokwethenjelwa phakathi kwabaningiUmphakeli we-PACs. Udinga ukuqinisekisa iziqu zabo kanye nekhwalithi yomkhiqizo. Uma udinga noma yiluphi usizo ekuthengeni i-PAC, ngicela ungazise. Singahlinzeka ngamasampula mahhala kanye nezinsizakalo zokukhetha. Ngibheke ngabomvu ukukubona!
