Yintoni umahluko phakathi kwe-ACH kunye ne-PAC?

I-aluminium chlorohydrate (ACH) kunye ne-polyaluminum chloride (PAC) zibonakala ngathi ziikhemikhali ezimbini ezahlukeneyo ezisetyenziswa njengeii-flocculants kunyango lwamanziEnyanisweni, i-ACH imele njengeyona nto ixineneyo kusapho lwe-PAC, inika umxholo ophezulu we-alumina kunye nobuncinci obunokufezekiswa kwiifom eziqinileyo okanye kwiifom zesisombululo esizinzileyo. Ezi zimbini zinemisebenzi ethile eyahlukileyo kancinci, kodwa iindawo zazo zokusetyenziswa zahlukile kakhulu. Eli nqaku liza kukunika ukuqonda okunzulu kwe-ACH kunye ne-PAC ukuze ukwazi ukukhetha imveliso efanelekileyo.

I-Polyaluminum chloride

I-Polyaluminum chloride (PAC) yi-polymer ephezulu yeemolekyuli enefomula yekhemikhali eqhelekileyo [Al2(OH)nCl6-n]m. Ngenxa yeempawu zayo ezikhethekileyo zeekhemikhali, ineendlela ezahlukeneyo zokusetyenziswa kwiindawo ezahlukeneyo. I-Polyaluminum chloride (PAC) idlala indima ebalulekileyo ekunyangweni kwamanzi, isusa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo, izinto ze-colloidal, kunye nezinto eziphilayo ezinganyibilikiyo ngeenkqubo zokuxinana. Ngokuthomalalisa amasuntswana, i-PAC ikhuthaza ukuhlanganiswa, iququzelele ukususwa kwawo emanzini. I-PAC, esetyenziswa rhoqo kunye nezinye iikhemikhali ezifana ne-PAM, iphucula umgangatho wamanzi, inciphisa ukudumba, kwaye ihlangabezana nemigangatho yoshishino.

Kwicandelo lokwenza amaphepha, i-PAC isebenza njengesixhobo sokucoca amanzi amdaka esingabizi kakhulu nesithintela ukungcola, iphucula unyango lwelindle kunye nobukhulu obungenalo i-rosin. Iphucula imiphumo yobukhulu, ithintela ungcoliseko lwelaphu kunye nenkqubo.

Izicelo zePAC zifikelela nakwishishini lezemigodi, zinceda ekuhlanjweni kwesinyithi kunye nokwahlulwahlulwa kwezimbiwa. Ziyahlula amanzi kwi-gangue, zinceda ekusetyenzisweni kwakhona, kwaye zikhupha amanzi kwidaka.

Ekukhupheni nasekucoceni i-petroleum, i-PAC isusa ukungcola, izinto eziphilayo ezinganyibilikiyo, kunye neentsimbi emanzini amdaka. Isusa kwaye isuse amaconsi eoli, izinzise imingxunya yamanzi kwaye ithintele umonakalo wokwakheka ngexesha lokugrumba ioyile.

Ukuprinta kunye nokudaya ilaphu kuyanceda kwikhono le-PAC lokunyanga amanzi amdaka ngobuninzi kunye nomxholo ophezulu wongcoliseko lwezinto eziphilayo. I-PAC ikhuthaza ukuhla okuqinileyo nokukhawulezileyo kweentyatyambo ze-alum, nto leyo efezekisa iziphumo ezintle zonyango.

I-Aluminiyam Chlorohydrate

I-ACH, i-Aluminium Chlorohydrate, enefomula yemolekyuli i-Al2(OH)5Cl·2H2O, yi-polymer compound engabonakaliyo ebonisa i-alkaliization degree ephezulu xa ithelekiswa ne-polyaluminum chloride kwaye ilandela i-aluminium hydroxide kuphela. Idlula kwi-bridge polymerization ngokusebenzisa amaqela e-hydroxyl, nto leyo ebangela ukuba i-molecule ibe nenani eliphezulu lamaqela e-hydroxyl.

Ifumaneka kwiiklasi zokunyanga amanzi kunye neekhemikhali zemihla ngemihla (udidi lwezithambiso), i-ACH iza ngohlobo lwepowder (eqinileyo) kunye nolwelo (isisombululo), apho i-solid ingumgubo omhlophe kwaye isisombululo silulwelo olungenambala nolucacileyo.

Ubungakanani bezinto ezinganyibilikiyo kunye ne-Fe buphantsi, ngoko ke bungasetyenziswa kwiikhemikhali zemihla ngemihla.

I-ACH ifumana izicelo ezahlukeneyo. Isebenza njengezinto ezisetyenziswa kakhulu kwiimveliso zamayeza kunye nezobuhle ezikhethekileyo, ngakumbi njengesithako esiphambili sokuthintela ukubila esaziwa ngokusebenza kwayo kakuhle, ukurhawuzelelwa okuncinci, kunye nokhuseleko. Ukongeza, i-ACH ibiza kakhulu kwaye ngenxa yoko ayisetyenziswa rhoqo njenge-flocculant emanzini okusela kunye nonyango lwamanzi amdaka kwimizi-mveliso. I-ACH ikwabonisa ukufuma okusebenzayo kwi-pH spectrum ebanzi kuneetyuwa zesinyithi eziqhelekileyo kunye nee-polyaluminum chloride ezisezantsi.
