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

Uma uthengaI-Polyaluminum Chloride(PAC), i-coagulant esetshenziswa kabanzi ezinqubweni zokwelashwa kwamanzi, kufanele kuhlolwe izinkomba eziningana ezibalulekile ukuqinisekisa ukuthi umkhiqizo uhlangabezana nezindinganiso ezidingekayo futhi uyafaneleka ekusetshenzisweni kwawo okuhlosiwe. Nazi izinkomba eziyinhloko okufanele ugxile kuzo:

1. Okuqukethwe kwe-Aluminium

Ingxenye eyinhloko esebenzayo ku-PAC yi-aluminium. Ukusebenza kahle kwe-PAC njenge-coagulant kuncike kakhulu ekugxilweni kwe-aluminium. Ngokuvamile, okuqukethwe kwe-aluminium ku-PAC kuvezwa njengephesenti le-Al2O3. I-PAC esezingeni eliphezulu ngokuvamile iqukethe phakathi kuka-28% kuya ku-30% we-Al2O3. Okuqukethwe kwe-aluminium kufanele kwanele ukuqinisekisa ukujiya okuphumelelayo ngaphandle kokusetshenziswa ngokweqile, okungaholela ekungasebenzi kahle kwezomnotho kanye nemiphumela emibi engaba khona ekhwalithini yamanzi.

2. Isisekelo

I-Basicity iyisilinganiso sezinga le-hydrolysis yezinhlobo ze-aluminium ku-PAC futhi ivezwa njengephesenti. Ibonisa isilinganiso sama-ion e-hydroxide kuma-aluminium esixazululweni. I-PAC enobubanzi be-basicity obungu-40% kuya ku-90% ivame ukuthandwa ekusetshenzisweni kokwelashwa kwamanzi. I-basicity ephezulu ivame ukusho ukuqina okusebenzayo kodwa kumele ilinganiswe nezidingo ezithile zenqubo yokwelashwa kwamanzi ukuze kugwenywe ukwelashwa ngokweqile noma okunganele.

4. Amazinga Okungahlanzeki

Ukuba khona kokungcola okufana nezinsimbi ezisindayo (isb. i-lead, i-cadmium) kufanele kube kuncane kakhulu. Lokhu kungcola kungaba yingozi empilweni futhi kuthinte ukusebenza kwe-PAC. I-PAC ehlanzekile kakhulu izoba namazinga aphansi kakhulu alokhu kungcola. Amashidi okuchaza anikezwa abakhiqizi kufanele afake ulwazi mayelana nokugcwala okuphezulu okuvunyelwe kwalokhu kungcola.

6. Ifomu (Eliqinile noma Eliwuketshezi)

I-PACitholakala kokubili ngesimo esiqinile (impuphu noma ama-granule) kanye nesimo soketshezi. Ukukhetha phakathi kwesimo esiqinile nesimanzi kuncike ezidingweni ezithile zesitshalo sokwelapha, okuhlanganisa izindawo zokugcina, imishini yokulinganisa, kanye nokulula kokuphatha. I-Liquid PAC ivame ukuthandwa ngenxa yokulula kokusetshenziswa kwayo kanye nokuncibilika okusheshayo, kanti i-solid PAC ingase ikhethwe ngenxa yokugcinwa kwayo isikhathi eside kanye nezinzuzo zokuhamba. Kodwa-ke, isikhathi sokuphila koketshezi sifushane, ngakho-ke akukhuthazwa ukuthenga uketshezi ngqo ukuze kugcinwe. Kunconywa ukuthenga okuqinile bese ukuzenzela ngokwakho ngokwesilinganiso.

7. Impilo Yeshelufu Nokuzinza

Ukuqina kwe-PAC ngokuhamba kwesikhathi kuthinta ukusebenza kwayo. I-PAC esezingeni eliphezulu kufanele ibe nesikhathi esizinzile sokuhlala eshalofini, igcine izakhiwo zayo kanye nokusebenza kwayo isikhathi eside. Izimo zokugcina, njengokushisa kanye nokuchayeka emoyeni, zingathinta ukuqina, ngakho-ke i-PAC kufanele igcinwe endaweni epholile, eyomile ezitsheni ezivaliwe ukuze kulondolozwe ikhwalithi yayo.

8. Ukuphumelela Ngezindleko

Ngaphezu kwekhwalithi yomkhiqizo, kubalulekile futhi ukucabangela ukusebenza kahle kwezindleko zokuthenga. Qhathanisa amanani, ukupakisha, ezokuthutha, nezinye izici zabahlinzeki abahlukene ukuze uthole imikhiqizo enokusebenza kahle kwezindleko okufanele.

Ngamafuphi, lapho uthenga i-polyaluminum chloride, kubalulekile ukucabangela okuqukethwe kwe-aluminium, ubunjalo, inani le-pH, amazinga okungcola, ukuncibilika, ifomu, isikhathi sokuphelelwa yisikhathi, ukusebenza kahle kwezindleko, kanye nokuhambisana nemithetho. Lezi zinkomba zinquma ngokuhlanganyela ukufaneleka nokusebenza kahle kwe-PAC ezinhlotsheni ezahlukene zokwelashwa kwamanzi.
