Mabda'a iyo codsiga polyaluminium chloride (PAC) sida wax ku oolnimada sare ee wakiilka ka saarida fluoride
Polyaluminum chloride (PAC) waa isku-darka polymer-ka aan organic, ka saariddeeda fluoride inta badan waxaa lagu xaqiiqsadaa labada hab ee soo socda:
Chemisorption: PAC waxay ku milmeen biyaha la sii daayay aluminium aluminium (Al³), oo lagu daray fluoride ion (F) si ay u sameeyaan hydrofluoric acid (HF) dhexdhexaad ah, ka dibna waxay sii samaysmeen roobab aluminium fluoride ah (AlF ₃).
Saamaynta roobabka wada-jirka ah: kolloid-ka aluminium hydroxide ee ay dhaliso PAC hydrolysis waxay dahaadhaa ion-ka fluorine ee bilaashka ah iyada oo loo marayo xayeysiinta dusha sare iyo qabashada mesh, oo ugu dambeyntii ka saarta kala soocida dareeraha adag.
Sababaha kordhinta qiyaasta PAC
Sababaha kordhinta qiyaasta polyaluminium chloride (PAC) waxaa lagu falanqeyn karaa xaaladaha deegaanka, isbeddelada tayada biyaha, sifooyinka wakiilka iyo habka hawlgalka. Macluumaadka goobidda waxaa loo habeeyey sida soo socota:
Tignoolajiyada midabaynta ee polymer iron sulfate (PFS) ee daabacaadda iyo midabaynta biyaha wasakhda ah
Faa'iidooyinka ugu muhiimsan ee tignoolajiyada midabaynta birta sulfate ee polymeric
Tilmaamaha isticmaalka badbaadada leh ee aluminium chloride (PAC)
Polyaluminum chloride (PAC, sida wakiilka daaweynta biyaha ee waxtarka sare leh) ayaa si weyn loogu isticmaalaa nadiifinta biyaha la cabbo, daaweynta biyaha wasakhda ah ee warshadaha iyo meelaha kale. Si kastaba ha ahaatee, badeecada kiimikaad ahaan, waa daxalaysa waxaana laga yaabaa inay keento khataro caafimaad. Warqadani waxay isku daraysaa xeerarka warshadaha iyo tallaabooyinka degdegga ah, waxay si nidaamsan u soo koobaysaa qodobbada hawlgalka badbaadada ee tixraaca xirfadlayaasha.
Polyaluminium Chloride (PAC) Tilmaamaha Dhameystiran ee Waxtarka-sare ee Daaweynta Biyaha Xalka tayada Biyaha ee la hagaajiyay
Polyaluminium Chloride (PAC), oo leh qaacidada kiimikada Al2 (OH) nCl6-nAl2 (OH)n?Cl6-nₘ, waa xinjiraha polymer-ka aan organic ahayn oo aad waxtar u leh. Waxaa lagu soo saaray hydrolysis iyo polymerization of aluminium milix, PAC waxay ku faantaa awoodo adsorption xoog leh, qulquli degdeg ah, iyo laqabsiga dhamaan pH ballaaran. Waxaa si weyn loogu isticmaalaa gudahanadiifinta biyaha la cabbo, daaweynta biyaha wasakhda ah ee warshadaha, maaraynta bulaacadaha magaalada, iyo qaar kaloo badan.

Waa maxay sababta polyaluminium chloride loogu isticmaali karaa defluoridation
Awooda saarista fluoride ee polyaluminum chloride (PAC) waxay ka timid sifooyinkeeda kiimikaad ee gaarka ah iyo habka ficilka, inta badan ku lug leh mabaadi'da soo socota:
Sidee dhirta daawaynta bulaacadaha u gaadhi karaan dheecaanka caadiga ah iyada oo loo marayo hagaajinta PAC ee hoos timaada xeerarka cusub ee deegaanka
Marka la eego xeerarka adag ee deegaanka, dhirta lagu daweeyo bulaacaduhu waxay u baahan yihiin inay gaaraan dheecaan caadi ah iyada oo loo marayo hagaajinta tignoolajiyada iyo hagaajinta maamulka. Sida wakiilka daaweynta biyaha ee asaasiga ah, xulashada macquulka ah iyo hagaajinta codsiga ee chloride polyaluminum (PAC) waa fure. Kuwa soo socdaa waa xalal ku salaysan siyaasadihii ugu dambeeyay iyo dhaqamada warshadaha
Daraasad ku saabsan la qabsiga polymeric ferric sulfate ee daaweynta heerkulka hooseeya iyo biyaha wasakhda ah ee hooseeya
Heerkulka hooseeya iyo daawaynta biyaha wasakhda ah ee hooseeya waa mid ka mid ah dhibaatooyinka farsamada ee goobta daaweynta biyaha.
