Polyaluminum chloride waa nadiifiye biyo nadiifin oo tayo sare leh, kaas oo nadiifin kara, ka saari kara ur xun, ka saari kara midabbada, iwm. Iyada oo ay ugu wacan tahay sifooyinka iyo faa'iidooyinka muuqda iyo baaxadda codsiga ballaaran, qiyaasta waxaa lagu dhimi karaa in ka badan 30% marka la barbar dhigo nadiifiyeyaasha biyaha dhaqameed, kharashkana waxaa lagu badbaadin karaa in ka badan 40%. Waxay noqotay nadiifiye biyo oo aad u fiican oo laga aqoonsan yahay gudaha iyo dibadda. Intaa waxaa dheer, polyaluminum chloride sidoo kale waxaa loo isticmaali karaa in lagu nadiifiyo tayada biyaha gaarka ah sida biyaha la cabbo iyo sahayda biyaha tuubada, sida ka saarista birta, ka saarista cadmium, ka saarista fluorine, ka saarista wasakhda shucaaca, iyo ka saarista saliidda.
Astaamaha PAC (Poly Aluminium Chloride):
Polyaluminum chloride waxay u dhaxaysaa ALCL3 iyo ALNCL6-NLm] halkaas oo m ay u taagan tahay heerka polymerization-ka halka n ay u taagan tahay heerka dhexdhexaadnimada badeecada PAC. Polyaluminum chloride oo loo soo gaabiyo PAC waxaa badanaa sidoo kale loo yaqaan polyaluminum chloride ama coagulant, iwm. Midabku waa jaalle ama huruud khafiif ah, bunni madow, adag oo resinous ah oo cawl madow ah. Badeecadu waxay leedahay sifooyin nuugis oo adag oo adag, inta lagu jiro habka hydrolysis-ka, hababka jireed iyo kiimikada sida xinjirowga, nuugista iyo roobabku way dhacaan.
Codsiga PAC (Poly Aluminium Chloride)
Polyaluminum chloride waxaa inta badan loo isticmaalaa saadka biyaha magaalooyinka iyo nadiifinta biyo-mareenka: biyaha webiga, biyaha kaydka, biyaha dhulka hoostiisa; nadiifinta sahayda biyaha warshadaha, daaweynta wasakhda magaalooyinka, soo kabashada walxaha waxtarka leh ee ku jira biyaha wasakhda warshadaha iyo haraaga qashinka, kor u qaadista dhoobo dhuxusha la shiiday ee biyaha wasakhda ah ee lagu dhaqo dhuxusha, wax soo saarka istaarijka Dib-u-warshadaynta istaarijka; polyaluminum chloride waxay nadiifin kartaa biyaha wasakhda ah ee warshadaha kala duwan, sida: daabacaadda iyo rinjiyeynta biyaha wasakhda ah, biyaha wasakhda ah ee maqaarka, biyaha wasakhda ah ee ka kooban fluorine, biyaha wasakhda ah ee birta culus, biyaha wasakhda ah ee ka kooban saliid, biyaha wasakhda ah ee lagu sameeyo warqadaha, biyaha wasakhda ah ee lagu dhaqo dhuxusha, macdanta biyaha wasakhda ah, biyaha wasakhda ah ee la kariyo, biyaha wasakhda ah ee birta, Ka shaqaynta biyaha wasakhda ah ee hilibka, iwm.; Polyaluminum chloride ee daaweynta wasakhda: cabbirka waraaqaha, sifeynta sonkorta, qaabaynta tuurista, ka hortagga laalaabyada maro, side kiciyaha, sibidhka si dhakhso leh u dejinta, walxaha ceeriin ee qurxinta.
Tusmada tayada ee PAC (polyaluminum chloride)
Saddexda tilmaame ee tayada ugu muhiimsan ee PAC (polyaluminum chloride) waa maxay? Cusbada, qiimaha PH, iyo alumina ee go'aamiya tayada polyaluminum chloride waa saddexda tilmaame ee tayada ugu muhiimsan ee polyaluminum chloride.
1. Cusbo.
Heerka hydroxylation ama alkalization ee qaab gaar ah oo ku jira PAC (polyaluminum chloride) waxaa loo yaqaan heerka aasaasiga ah ama alkalinity. Guud ahaan waxaa lagu muujiyaa saamiga molar ee boqolkiiba aluminium hydroxide B=[OH]/[Al]. Milixda milixda waa mid ka mid ah tilmaamayaasha ugu muhiimsan ee polyaluminum chloride, kaas oo si dhow ula xiriira saamaynta flocculation. Inta badan ee fiirsashada biyaha ceeriin ah iyo inta milixda milixda sare leh, ayaa ka sii wanaagsan saamaynta flocculation. Marka la soo koobo, inta u dhaxaysa biyaha ceeriin ah ee 86~10000mg/L, milixda ugu fiican ee polyaluminum chloride waa 409~853, iyo astaamo kale oo badan oo polyaluminum chloride ah ayaa la xiriira milixda.
2. qiimaha pH.
pH-ga xalka PAC (polyaluminum chloride) sidoo kale waa tilmaame muhiim ah. Waxay u taagan tahay xaddiga OH- ee xaaladda xorta ah ee xalka. Qiimaha pH-ga ee polyaluminum chloride guud ahaan wuu kordhaa marka uu kordho aasaaska, laakiin dareereyaasha leh isku-darka kala duwan, ma jiro xiriir u dhigma oo u dhexeeya qiimaha pH iyo aasaaska. Dareeraha leh isku-darka milixda leh waxay leeyihiin qiimayaal pH oo kala duwan marka diiraddu ay kala duwan tahay.
3. Waxyaabaha Alumina ka kooban.
Waxyaabaha alumina ku jira ee ku jira PAC (polyaluminum chloride) waa cabbir lagu cabbiro qaybaha wax ku oolka ah ee badeecada, kuwaas oo xiriir gaar ah la leh cufnaanta qaraabada ah ee xalka. Guud ahaan, marka la eego cufnaanta qaraabada ah, ayaa sii kordheysa waxa ku jira alumina. Dheefsashada polyaluminum chloride waxay la xiriirtaa waxa ku jira alumina, dhefashadana way sii kordheysaa marka ay korodho waxa ku jira alumina. Xaaladaha isku midka ah iyo isku-darka alumina, dhefashada polyaluminum chloride way ka hooseysaa tan aluminium sulfate, taas oo aad ugu habboon gaadiidka iyo isticmaalka.
