I-Polyaluminum chloride sisicoci samanzi esisebenza kakuhle, esinokucoca iintsholongwane, sisuse ivumba elibi, sisuse umbala, njl. Ngenxa yeempawu zaso ezibalaseleyo kunye neenzuzo kunye noluhlu olubanzi lokusetyenziswa, idosi ingancitshiswa ngaphezulu kwe-30% xa kuthelekiswa nezicoci zamanzi zemveli, kwaye iindleko zingagcinwa ngaphezulu kwe-40%. Ibe sisicoci samanzi esibalaseleyo esaziwayo ekhaya nakwamanye amazwe. Ukongeza, i-polyaluminum chloride ingasetyenziselwa ukucoca umgangatho wamanzi okhethekileyo njengokuhambisa amanzi okusela kunye nokubonelela ngamanzi empompini, njengokususa isinyithi, ukususa i-cadmium, ukususa i-fluorine, ukususa ungcoliseko olune-radioactive, kunye nokususa i-oyile etyibilikayo.
Iimpawu ze-PAC (i-Poly Aluminium Chloride):
I-Polyaluminum chloride iphakathi kwe-ALCL3 kunye ne-ALNCL6-NLm] apho u-m emele inqanaba le-polymerization kwaye u-n emele inqanaba lokungathathi cala kwemveliso ye-PAC. I-Polyaluminum chloride efinyeziweyo njenge-PAC idla ngokubizwa ngokuba yi-polyaluminum chloride okanye i-coagulant, njl. Umbala utyheli okanye utyheli okhanyayo, umdaka omnyama, i-resinous solid emnyama. Imveliso ineempawu eziqinileyo zokufunxa, kwaye ngexesha lenkqubo ye-hydrolysis, iinkqubo zomzimba nezekhemikhali ezifana nokufunxa, ukufunxa kunye nokuna kwemvula ziyenzeka.
Ukusetyenziswa kwe-PAC (i-Poly Aluminium Chloride):
I-Polyaluminum chloride isetyenziswa kakhulu ekunikezelweni kwamanzi ezidolophini nasekucocweni kwemijelo yamanzi: amanzi omlambo, amanzi edama, amanzi angaphantsi komhlaba; ukucocwa kwamanzi emizi-mveliso, unyango lwelindle lasezidolophini, ukubuyiswa kwezinto eziluncedo emanzini amdaka emizi-mveliso kunye nenkunkuma, ukukhuthaza ukugalelwa kwamalahle acoliweyo emanzini amdaka okuhlamba amalahle, ukwenziwa kwesitatshi Ukuphinda kusetyenziswe istatshi; i-polyaluminium chloride inokucoca amanzi amdaka emizi-mveliso eyahlukeneyo, anje: ukuprinta nokudaya amanzi amdaka, amanzi amdaka esikhumba, amanzi amdaka aqulethe i-fluorine, amanzi amdaka esinyithi esinzima, amanzi amdaka aqulethe ioyile, ukwenza iphepha, amanzi amdaka okuhlamba amalahle, ukumba amanzi amdaka, ukwenziwa kwamanzi amdaka, amanzi amdaka okwenziwa ngesinyithi, ukucubungula inyama, njl.njl.; I-Polyaluminum chloride yonyango lwelindle: ubungakanani bephepha, ukucocwa kweswekile, ukubumba i-casting, ukuthintela imibimbi, isithwali se-catalyst, ukuseta ngokukhawuleza kwesamente yokucocwa kwamayeza, izinto zokuhlobisa.
Isalathisi somgangatho we-PAC (i-polyaluminum chloride)
Zeziphi ezona zibonakaliso zintathu zibalulekileyo zomgangatho we-PAC (i-polyaluminum chloride)? Ubungakanani betyuwa, ixabiso le-PH, kunye nomxholo we-alumina ogqiba umgangatho we-polyaluminum chloride zezona zibonakaliso zintathu zibalulekileyo zomgangatho we-polyaluminum chloride.
1. Ubutyuwa.
Iqondo le-hydroxylation okanye i-alkaliization yefomu ethile kwi-PAC (i-polyaluminum chloride) libizwa ngokuba liqondo le-basicity okanye i-alkalinity. Ngokuqhelekileyo libonakaliswa yi-molar ratio ye-aluminium hydroxide B=[OH]/[Al] percentage. I-salinity yenye yezona zibonakaliso zibalulekileyo ze-polyaluminum chloride, enxulumene kakhulu ne-flocculation effect. Okukhona uxinzelelo lwamanzi aluhlaza luphezulu kwaye i-salinity iphezulu, kokukhona i-flocculation effect ingcono. Ngamafutshane, kuluhlu lwe-turbidity yamanzi aluhlaza ye-86 ~ 10000mg/L, i-salinity efanelekileyo ye-polyaluminum chloride yi-409 ~ 853, kwaye ezinye iimpawu ezininzi ze-polyaluminum chloride zinxulumene ne-salinity.
2. Ixabiso le-pH.
I-pH yesisombululo se-PAC (polyaluminum chloride) nayo ikwasisalathisi esibalulekileyo. Imele ubungakanani be-OH- kwimeko ekhululekileyo kwisisombululo. Ixabiso le-pH le-polyaluminum chloride liyanda ngokunyuka kwe-basicity, kodwa kwizinto ezimanzi ezineenxalenye ezahlukeneyo, akukho budlelwane obuhambelanayo phakathi kwexabiso le-pH kunye ne-basicity. Izinto ezimanzi ezine-salinity concentration efanayo zine-pH values ezahlukeneyo xa i-concentration yahlukile.
3. Umxholo we-alumina.
Umxholo we-alumina kwi-PAC (i-polyaluminum chloride) ngumlinganiselo wezinto ezisebenzayo zemveliso, enobudlelwane obuthile noxinano lwesisombululo. Ngokubanzi, xa uxinano lukhula, konyuka umxholo we-alumina. Uxinano lwe-polyalumina chloride lunxulumene nomxholo we-alumina, kwaye uxinano luyanda ngokunyuka komxholo we-alumina. Phantsi kweemeko ezifanayo kunye noxinano olufanayo lwe-alumina, uxinano lwe-polyalumina chloride luphantsi kunolwe-aluminium sulfate, olulungele ukuthuthwa nokusetyenziswa.
