Yiziphi izinkomba eziphambili zokugxila lapho uthenga i-polyaluminum chloride?

Lapho uthengaPolyaluminum chloride(I-PAC), i-coagulant esetshenziswa kabanzi ezinhlanganweni zokwelashwa kwamanzi, izikhombisi eziningana ezibalulekile kufanele zihlolwe ukuze umkhiqizo uhlangabezana namazinga adingekayo futhi ulungele uhlelo lwayo oluhlosiwe. Ngezansi kwezinkomba eziphambili ukugxila ku:

1. Okuqukethwe kwe-aluminium

Ingxenye esebenzayo esebenzayo ku-PAC yi-aluminium. Ukusebenza kwe-PAC njenge-coabulayo ikakhulukazi kuncike ekuqoqweni kwe-aluminium. Imvamisa, okuqukethwe kwe-aluminium ku-PAC kuvezwa njengephesenti le-Al2o3. I-PAC esezingeni eliphakeme ngokuvamile iqukethe phakathi kuka-28% kuya ku-30% Al2o3. Okuqukethwe kwe-aluminium kufanele kwanele ukuqinisekisa ukubheja okusebenzayo ngaphandle kokusebenzisa ngokweqile, okungaholela ekusebenzeni ngokweqile, okungaholela ekusebenzeni kahle kwezomnotho kanye nemiphumela emibi emazingeni athile ngekhwalithi yamanzi.

2. Isisekelo

I-BAIRASITITITITITITIty iyisilinganiso sezinga le-hydrolysis yezinhlobo ze-aluminium ku-PAC futhi livezwa njengephesenti. Kubonisa isilinganiso se-hydroxide ku-aluminium ion kwikhambi. I-PAC enebanga eliyisisekelo lama-40% kuya ku-90% kuvame ukuthandwa kwezicelo zokwelashwa kwamanzi. Isisekelo esiphakeme kwesinye isikhathi sibonisa ukubheja okusebenzayo kepha kufanele silinganise ngokumelene nezidingo ezithile zenqubo yokwelashwa kwamanzi ukugwema ngaphezulu noma ngaphansi kokwelashwa.

4. Amazinga okuphelelwa amandla

Ukuba khona kokungcola okufana nezinsimbi ezisindayo (isib. Ukuhola, i-cadmium) kufanele kube mincane. Lokhu kungcola kungabeka izingozi zempilo futhi kuthinte ukusebenza kwe-PAC. I-PASH PRINTITY PAC izoba namazinga aphansi kakhulu engcola. Amashidi acacisiwe ahlinzekwe ngabakhiqizi kufanele afake imininingwane ekugxileni okuvumelekile kwalokhu kungcola.

I-6. Ifomu (eliqinile noma liketshezi)

Isinyatheloiyatholakala zombili eziqinile (i-powder noma ama-granules) kanye namafomu awuketshezi. Ukukhetha phakathi kwamafomu aqinile noketshezi kuncike kwizidingo ezithile zesitshalo sokwelashwa, kufaka phakathi izindawo zokugcina, imishini yokudla, nokuphathwa kalula. I-PAC ye-Liquid ivame ukuthandwa ngokulula ukusetshenziswa kwayo nokuchithwa okusheshayo, kanti kungenzeka ukuthi i-PAC eqinile ingakhethwa ngezinzuzo zokugcina isikhathi eside nezinzuzo zokuhamba. Kodwa-ke, impilo eshalofini ye-liquid imfushane, ngakho-ke ayinconyelwanga ukuthenga uketshezi ngokuqondile kwisitoreji. Kunconywa ukuthenga okuqinile futhi kwenze ngokwakho ngokuya ngesilinganiso.

7. Impilo yeshelufu nokuqina

Ukuqina kwe-PAC ngokuhamba kwesikhathi kuthinta ukusebenza kwayo. I-PAC esezingeni eliphakeme kufanele ibe nempilo eqinile yeshelume, igcina izakhiwo zayo kanye nokusebenza kahle kwezikhathi ezengeziwe. Izimo zokugcina, njengokushisa nokuchayeka komoya, kungathinta ukuqina, ngakho-ke i-PAC kufanele igcinwe endaweni epholile, eyomile ezitsheni ezivalekile ukuze ilondoloze ikhwalithi yayo.

8. Ukusebenza kwezindleko

Ngaphezu kwekhwalithi yomkhiqizo, kuyadingeka futhi ukubheka ukusebenza kwezindleko zokuthengwa kwempahla. Qhathanisa amanani, ukupakisha, ezokuhamba, nezinye izinto zabathengisi abahlukahlukene ukuthola imikhiqizo esebenza kahle izindleko.

Ngamafuphi, lapho uthenga i-polyaluminum chloride, kubalulekile ukucubungula okuqukethwe kwe-aluminium, okuyisisekelo, amazinga e-PH, amazinga okungcola, i-solubity, ifomu, ukuhambisana kwezindleko, kanye nokulandela izindleko, kanye nokulandela izindleko. Lezi zinkomba ngokuhlangene zinquma ukufaneleka kanye nokusebenza kahle kwe-PAC ngezinhlelo ezahlukahlukene zokwelashwa kwamanzi.
