Yiziphi izinkomba eziyinhloko okufanele ugxile kuzo lapho uthenga i-Polyaluminium Chloride?

Lapho uthengaI-Polyaluminium chloride(PAC), i-coagulant esetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi, izinkomba ezimbalwa ezibalulekile kufanele zihlolwe ukuze kuqinisekiswe ukuthi umkhiqizo uhlangabezana nezindinganiso ezidingekayo futhi ulungele ukusetshenziswa okuhlosiwe. Ngezansi izinkomba eziphambili okufanele ugxile kuzo:

1. Okuqukethwe kwe-Aluminium

Ingxenye eyinhloko esebenzayo ku-PAC i-aluminium. Ukusebenza kwe-PAC njenge-coagulant kuncike kakhulu ekugxilweni kwe-aluminium. Ngokuvamile, okuqukethwe kwe-aluminium ku-PAC kuvezwa njengephesenti le-Al2O3. I-PAC yekhwalithi ephezulu ngokuvamile iqukethe phakathi kuka-28% kuya ku-30% Al2O3. Okuqukethwe kwe-aluminium kufanele kube ngokwanele ukuqinisekisa ukuhlangana okuphumelelayo ngaphandle kokusetshenziswa ngokweqile, okungaholela ekungasebenzi kahle kwezomnotho kanye nemiphumela emibi engaba khona kukhwalithi yamanzi.

2. Isisekelo

Isisekelo isilinganiso sezinga le-hydrolysis yohlobo lwe-aluminium ku-PAC futhi sivezwa njengephesenti. Ibonisa isilinganiso se-hydroxide ne-aluminium ions esixazululweni. I-PAC enobubanzi obuyisisekelo obungu-40% ukuya ku-90% ivamise ukuncanyelwa ukufakwa kokuhlanza amanzi. Isisekelo esiphezulu ngokuvamile sisho ukuhlangana okuphumelelayo kodwa kufanele kulinganiswe nezimfuneko ezithile zenqubo yokuhlanza amanzi ukuze kugwenywe ukuphuza ngokweqile noma kancane.

4. Amazinga Okungcola

Ukuba khona kokungcola okufana nezinsimbi ezisindayo (isb, umthofu, i-cadmium) kufanele kube kuncane. Lokhu kungcola kungadala ubungozi bezempilo futhi kuthinte ukusebenza kwe-PAC. I-PAC ehlanzekile izoba namazinga aphansi kakhulu okungcola okunjalo. Amashidi ezicaciso anikezwe abakhiqizi kufanele afake ulwazi mayelana nokugxilisa okuphezulu okuvumelekile kwalokhu kungcola.

6. Ifomu (Okuqinile noma Okuwuketshezi)

I-PACitholakala kuzo zombili izinhlobo eziqinile (impuphu noma ama-granules) kanye namafomu oketshezi. Ukukhetha phakathi kwamafomu aqinile nawuketshezi kuncike ezidingweni ezithile zesikhungo sokwelapha, okuhlanganisa izindawo zokugcina, okokusebenza kokudosa, kanye nokubamba kalula. I-Liquid PAC ivamise ukuncanyelwa ngenxa yokusebenziseka kwayo kalula nokuhlakazeka ngokushesha, kuyilapho i-PAC eqinile ingase ikhethelwe izinzuzo zesikhathi eside zokulondoloza nezokuthutha. Kodwa-ke, impilo yeshalofu ye-liquid ifushane, ngakho-ke akunconywa ukuthenga uketshezi ngokuqondile ukuze ugcinwe. Kunconywa ukuthenga okuqinile futhi uzenzele ngokwesilinganiso.

7. Ukuphila Kweshelufu Nokuzinza

Ukuzinza kwe-PAC ngokuhamba kwesikhathi kuthinta ukusebenza kwayo. I-PAC yekhwalithi ephezulu kufanele ibe neshelufu elizinzile, igcine izakhiwo zayo nokusebenza kwayo isikhathi eside. Izimo zesitoreji, njengezinga lokushisa nokuchayeka emoyeni, zingaba nomthelela ekuzinzeni, ngakho i-PAC kufanele igcinwe endaweni epholile, eyomile ezitsheni ezivaliwe ukuze kugcinwe ikhwalithi yayo.

8. Ukusebenza Kwezindleko

Ngaphezu kwekhwalithi yomkhiqizo, kuyadingeka futhi ukucabangela ukuphumelela kwezindleko zokuthenga. Qhathanisa izintengo, ukupakishwa, ezokuthutha, nezinye izici zabahlinzeki abahlukahlukene ukuze uthole imikhiqizo enezindleko ezifanelekile.

Kafushane, lapho uthenga i-polyaluminium chloride, kubalulekile ukucabangela okuqukethwe kwe-aluminium, okuyisisekelo, inani le-pH, amazinga okungcola, ukuncibilika, ifomu, impilo yeshalofu, ukuphumelela kwezindleko, nokuhambisana nomthetho. Lezi zinkomba ngokuhlangene zinquma ukufaneleka nokusebenza kahle kwe-PAC ekufakweni okuhlukahlukene kokuhlanza amanzi.
