Polyaluminum chloride waxay leedahay nuugid, qoyaan, roobab iyo sifooyin kale, xasilloonideedu waa mid liidata, daxal leh, sida si kama' ah loogu daadiyo maqaarka si degdeg ah loo dhaqo. Shaqaalaha wax soo saarka waa inay xirtaan guud ahaan, maaskaro, galoofisyo, xirtaan kabo caag ah. Polyaluminum chloride waxay leedahay faa'iidooyinka xasilloonida qalajinta buufinta wanaagsan, aagga biyaha ballaaran, xawaaraha hydrolysis-ka degdegga ah, awoodda nuugista xooggan, sameynta ubaxa alum ee ballaaran, roobab degdeg ah, wasakhda biyaha oo yar iyo waxqabadka fuuq-baxa wanaagsan. Badeecadaha qalajinta buufinta waxay hubin karaan badbaadada, waxay yareyn karaan shilalka biyaha, biyaha la cabbo ee dadka deegaanka waa kuwo aad u ammaan ah oo la isku halleyn karo. Sidaa darteed, polyaluminum chloride, oo sidoo kale loo yaqaan polyaluminum chloride oo waxtar sare leh, PAC oo waxtar sare leh ama qalajinta buufinta waxtarka sare leh ee polyaluminum chloride. Polyaluminum chloride waxay ku habboon tahay biyaha cayriin oo leh wasakh kala duwan, oo leh codsiyo pH oo kala duwan, laakiin saameynteeda fadhiisinta ayaa aad uga yar tan polyacrylamide.
Aasaaska polyaluminum chloride waa tusmo muhiim ah oo ku jirta polyaluminum, gaar ahaan alaabta polyaluminum ee heerka biyaha la cabbo. Saldhigga milixda oo hooseeya, qiimaha ayaa sarreeya, iibsade kasta wuxuu u shaqeyn karaa iyadoo loo eegayo xaaladda dhabta ah ee soo saaraha. Intaa waxaa dheer, walxaha ceeriin ee kala duwan, hababka kala duwan ee wax soo saarka ee alaabada polyaluminum chloride way kala duwan yihiin saldhigga milixda, taas oo u baahan soo saaraha inuu hagaajiyo. Faa'iidooyinka dhaqaale ee wax soo saarka iyo isticmaalka waxaa si weyn loo kordhin karaa iyadoo la kordhinayo heerka saldhigga milixda ee alaabada polyaluminum chloride. Aasaaska waxaa laga kordhiyay 65% ilaa 92%, qiimaha alaabta ceeriin waxaa lagu dhimi karaa 20%, kharashka isticmaalkana waxaa lagu dhimi karaa 40%.
Midabka polyaluminum chloride guud ahaan wuxuu leeyahay midabyo cad, jaalle, midab madow, midabyo kala duwan oo polyaluminum chloride ah oo ku jira codsiga iyo tiknoolajiyada wax soo saarka sidoo kale aad ayuu uga duwan yahay. Polyaluminum chloride oo leh maaddada trialoxide ee heerka qaranka oo u dhexeeya 27% ilaa 30% waa inta badan budo adag oo kha-jaalle ah ilaa jaalle iyo jaalle khafiif ah. Noocyadan polyaluminum chloride waxay leeyihiin milmi biyo oo wanaagsan. Inta lagu jiro habka kala dirida, iyadoo la raacayo isbeddellada jireed iyo kuwa kiimikada sida electrochemistry, xinjirowga, nuugista iyo roobka, flocs-ku waxay sameeyaan si dhakhso ah oo qaro weyn, waxay leeyihiin firfircooni sare, si dhakhso ah ayay u soo daadanayaan, waxayna leeyihiin saameyn nadiifin cad oo ku saabsan biyaha wasakhda sare. Polyaluminum chloride cad sababtoo ah waxaa loo yaqaanaa daahirnimo sare oo aan bir ahayn oo ah polyaluminum chloride cad, ama polyaluminum chloride cad oo heer cunto ah, marka la barbar dhigo polyaluminum chloride-kiisa waa badeecadaha tayada ugu sarreeya, walxaha cayriin ee ugu weyn waa budada aluminium hydroxide tayo sare leh, hydrochloric acid, habka wax soo saarka waa habka ugu horumarsan ee lagu qalajiyo buufinta tiknoolajiyada gudaha. Polyaluminium chloride cad waxaa loo isticmaalaa wakiilka cabbirka waraaqaha, kala saarista midabka iyo caddeynta sonkorta, maqaarka maqaarka, daawada, qurxinta iyo tuurista saxda ah iyo daaweynta biyaha.
Maaddada cayriin ee polyaluminium chloride ee jaalaha ah waa budada calcium aluminate, hydrochloric acid, bauxite, oo inta badan loo isticmaalo daaweynta wasakhda iyo daaweynta biyaha la cabbo, walaxda cayriin ee loo isticmaalo daaweynta biyaha la cabbo waa budada aluminium hydroxide, hydrochloric acid, waxaa jira budada calcium aluminate yar, habka la qaato waa habka shaandhada qaabka saxanka ama habka qalajinta buufinta. Daaweynta biyaha la cabbo, waddanku wuxuu leeyahay shuruudo adag oo ku saabsan biraha culus, sidaa darteed labadaba walxaha ceeriin iyo habka wax soo saarka ayaa ka wanaagsan tan polyaluminum chloride. Polyaluminium chloride huruud ah waxaa guud ahaan lagu soo saaraa qalajinta durbaanka ama qalajinta munaaradda buufinta. Walxaha cayriin ee polyaluminum chloride bunni ah waa budada calcium aluminate, hydrochloric acid, bauxite iyo budada birta. Habka wax soo saarka waa in la qaato habka qalajinta durbaanka, guud ahaan inta badan loo isticmaalo daaweynta wasakhda, sababtoo ah budada birta ayaa lagu daraa gudaha si midabku u noqdo bunni, budada birta badan ayaa lagu daraa, midabkuna waa madow, budada birta haddii in ka badan xaddi go'an muddo ka dib waxaa sidoo kale loo yaqaan polyaluminum-iron chloride, daaweynta wasakhda waxay leedahay saameyn aad u fiican.
