Xa uthengaPolyaluminium kloride(PAC), i-coagulant esetyenziswa ngokubanzi kwiinkqubo zokunyanga kwamanzi, izikhombisi ezininzi eziphambili kufuneka zihlolwe ukuqinisekisa ukuba imveliso ihlangabezana nemigangatho efunekayo kwaye ifanelekile kwisicelo sayo. Ngezantsi zizalathisi eziphambili zokugxila kuzo:
1. Umxholo weAluminiyam
Elona candelo lisebenzayo kwiPAC yialuminiyam. Ukusebenza kwePAC njengecoagulant ubukhulu becala kuxhomekeke kuxinzelelo lwealuminiyam. Ngokuqhelekileyo, umxholo we-aluminium kwi-PAC uboniswa njengepesenti ye-Al2O3. Umgangatho ophezulu wePAC jikelele uqulathe phakathi kwe-28% ukuya kwi-30% Al2O3. Umxholo we-aluminium kufuneka ube nokwaneleyo ukuqinisekisa ukudibanisa okusebenzayo ngaphandle kokusetyenziswa ngokugqithiseleyo, oku kunokukhokelela ekungaphumeleli kwezoqoqosho kunye nemiphumo emibi enokubakho kumgangatho wamanzi.
2. Isiseko
Okusisiseko ngumlinganiselo weqondo le-hydrolysis yohlobo lwe-aluminiyam kwi-PAC kwaye ichazwa njengepesenti. Ibonisa umlinganiselo we-hydroxide kwi-aluminium ion kwisisombululo. I-PAC enoluhlu olusisiseko lwe-40% ukuya kwi-90% idla ngokukhethwa kwizicelo zokucoca amanzi. Isiseko esiphezulu sisoloko sithetha ukujiya okusebenzayo ngakumbi kodwa kufuneka silungelelaniswe ngokuchasene neemfuno ezithile zenkqubo yokucoca amanzi ukuphepha ukunyangwa ngokugqithisileyo okanye ngaphantsi.
4. Amanqanaba okungcola
Ubukho bobumdaka obufana neentsimbi ezinzima (umzekelo, ilothe, i-cadmium) kufuneka bube buncinci. Oku kungcola kunokubangela imingcipheko yempilo kwaye kuchaphazele ukusebenza kwePAC. I-PAC yococeko oluphezulu iya kuba namanqanaba asezantsi kakhulu ongcoliseko olunjalo. Amaxwebhu enkcazo abonelelwe ngabavelisi kufuneka abandakanye ulwazi ngobuninzi obuvumelekileyo bobu kungcola.
6. Ifom (Eqinile okanye eManzi)
PACifumaneka kuzo zombini eziqinileyo (umgubo okanye iigranules) kunye neefom ezingamanzi. Ukhetho phakathi kweefom eziqinileyo kunye nolwelo kuxhomekeke kwiimfuno ezithile zesityalo sonyango, kubandakanywa neendawo zokugcina, izixhobo zokudosa, kunye nokulula ukuphatha. Ulwelo lwePAC lusoloko lukhethwa ngokulula kwayo ukusetyenziswa kunye nokupheliswa ngokukhawuleza, ngelixa iPAC eqinileyo isenokukhethwa kugcino lwexesha elide kunye noncedo kwezothutho. Nangona kunjalo, ubomi beshelufu yolwelo bufutshane, ngoko akukhuthazwa ukuba uthenge ulwelo ngokuthe ngqo ukugcinwa. Kunconywa ukuba uthenge okuqinileyo kwaye uzenzele ngokwawo ngokomlinganiselo.
7. Ubomi beShelf kunye nokuzinza
Uzinzo lwePAC ekuhambeni kwexesha luchaphazela ukusebenza kwayo. Umgangatho ophezulu wePAC kufuneka ube neshelufu ezinzileyo, igcine iipropathi zayo nokusebenza kwayo ixesha elide. Iimeko zokugcina, ezifana nobushushu kunye nokuvezwa emoyeni, kunokuchaphazela uzinzo, ngoko ke iPAC kufuneka igcinwe kwindawo epholileyo, eyomileyo kwizikhongozeli ezivaliweyo ukugcina umgangatho wayo.
8. Iindleko-Ngempumelelo
Ukongeza kumgangatho wemveliso, kukwafuneka ukuba kuqwalaselwe iindleko zokuthengwa kwempahla. Thelekisa amaxabiso, ukupakishwa, uthutho, kunye nezinye izinto zababoneleli abahlukeneyo ukuze ufumane iimveliso ezinexabiso elifanelekileyo.
Isishwankathelo, xa kuthengwa i-polyaluminium chloride, kubalulekile ukuqwalasela umxholo we-aluminium, isiseko, ixabiso le-pH, amanqanaba okungcola, i-solubility, ifom, i-shelf life, i-cost-effectiveness, kunye nokuthotyelwa kokulawula. Ezi zalathi zidibene zimisela ukufaneleka nokusebenza kakuhle kwePAC kwizicelo ezahlukeneyo zokucocwa kwamanzi.
