I-Polyaluminum chloride ine-adsorption, i-condensation, imvula nezinye izakhiwo, ukuqina kwayo kubi, kuyagqwala, njengokuchitheka ngengozi esikhumbeni ukuze kugezwe ngokushesha. Abasebenzi bokukhiqiza kufanele bagqoke ama-overalls, imaski, amagilavu, bagqoke amabhuzu erabha. I-Polyaluminum chloride inezinzuzo zokuqina okuhle kokomisa ngokufutha, indawo ebanzi yamanzi, isivinini se-hydrolysis esheshayo, amandla aqinile okomisa, ukwakheka kwezimbali ezinkulu ze-alum, imvula esheshayo, ukugcwala kwamanzi okuphansi kanye nokusebenza kahle kokuphelelwa amanzi emzimbeni. Imikhiqizo yokomisa ngokufutha ingaqinisekisa ukuphepha, inciphise izingozi zamanzi, amanzi okuphuza kubantu abahlala khona aphephile kakhulu futhi athembekile. Ngakho-ke, i-polyaluminum chloride, ebizwa nangokuthi i-polyaluminum chloride esebenza kahle kakhulu, i-PAC esebenza kahle kakhulu noma i-polyaluminum chloride yokomisa ngokufutha esebenza kahle kakhulu. I-Polyaluminum chloride ifanelekela amanzi aluhlaza ane-turbidity ehlukahlukene, enezinhlobo eziningi ze-pH, kodwa umphumela wayo wokuthungwa uphansi kakhulu kunowe-polyacrylamide.
Ukubaluleka kwe-polyaluminum chloride kuyinkomba ebaluleke kakhulu ku-polyaluminum, ikakhulukazi emikhiqizweni yamanzi okuphuza ye-polyaluminum. Uma isisekelo sikasawoti siphansi, intengo iyanda, umthengi ngamunye angasebenza ngokwesimo sangempela somkhiqizi. Ngaphezu kwalokho, izinto zokusetshenziswa ezahlukene, izinqubo ezahlukene zokucubungula ukukhiqizwa kwemikhiqizo ye-polyaluminum chloride zihlukile kusisekelo sikasawoti, okudinga umenzi ukuthi alungise. Izinzuzo zomnotho zokukhiqiza nokusetshenziswa zingandiswa kakhulu ngokwandisa izinga lesisekelo sikasawoti semikhiqizo ye-polyaluminum chloride. Ukubaluleka kukhushulwa kusuka ku-65% kuya ku-92%, izindleko zezinto zokusetshenziswa zingancishiswa ngo-20%, kanti izindleko zokusebenzisa zingancishiswa ngo-40%.
Umbala we-polyaluminum chloride ngokuvamile unombala omhlophe, ophuzi, onsundu, imibala ehlukene ye-polyaluminum chloride ekusetshenzisweni nasekukhiqizweni kwayo ihluke kakhulu. I-polyaluminum chloride enokuqukethwe kwe-trialoxide ebangeni lezindinganiso zikazwelonke kusukela ku-27% kuya ku-30% ikakhulukazi iyimpuphu eqinile ye-kha-yellow kuya kwephuzi kanye nephuzi elikhanyayo. Lezi zinhlobo ze-polyaluminum chloride zinokuncibilika okuhle kwamanzi. Enkambisweni yokuncibilika, ngezinguquko zomzimba nezamakhemikhali ezifana ne-electrochemistry, i-coagulation, i-adsorption kanye nemvula, ama-floc akha ngokushesha futhi ajiyile, anomsebenzi ophezulu, asheshe ashe, futhi abe nomphumela ocacile wokuhlanzwa emanzini aphezulu ane-turbidity. I-polyaluminum chloride emhlophe ngoba yaziwa ngokuthi i-polyaluminum chloride emhlophe engeyona insimbi, noma i-polyaluminum chloride emhlophe yezinga lokudla, uma iqhathaniswa ne-polyaluminum chloride yayo iyimikhiqizo esezingeni eliphezulu, izinto ezisetshenziswayo eziyinhloko yi-aluminium hydroxide powder esezingeni eliphezulu, i-hydrochloric acid, inqubo yokukhiqiza iyindlela yokwemisa yokufutha yasekhaya ethuthuke kakhulu. I-polyaluminium chloride emhlophe isetshenziswa ekwenzeni i-papermaking sizeing agent, i-sugar decolorizing and clarifying agent, isikhumba sokushisa, imithi, izimonyo kanye nokucubungula okunembile kanye nokwelashwa kwamanzi.
Izinto zokusetshenziswa ze-polyaluminium chloride ephuzi yi-calcium aluminate powder, i-hydrochloric acid, i-bauxite, esetshenziswa kakhulu ekwelapheni indle kanye nokwelashwa kwamanzi okuphuza, izinto zokusetshenziswa ezisetshenziswa ekwelapheni amanzi okuphuza yi-aluminium hydroxide powder, i-hydrochloric acid, kune-calcium aluminate powder encane, inqubo esetshenziswayo inqubo yokuhlunga uhlaka lwepuleti noma inqubo yokomisa ngesifutho. Ukwelashwa kwamanzi okuphuza, izwe linezidingo eziqinile zezinsimbi ezisindayo, ngakho-ke kokubili izinto zokusetshenziswa kanye nenqubo yokukhiqiza kungcono kune-tan polyaluminum chloride. I-polyaluminium chloride ephuzi ngokuvamile ikhiqizwa ngokumisa ngegubhu noma ngokumisa nge-spray tower. Izinto zokusetshenziswa ze-polyaluminum chloride ensundu yi-calcium aluminate powder, i-hydrochloric acid, i-bauxite kanye ne-iron powder. Inqubo yokukhiqiza iwukusebenzisa indlela yokomisa ngegubhu, ngokuvamile esetshenziswa kakhulu ekwelapheni indle, ngoba i-iron powder ifakwa ngaphakathi ukuze umbala ube nsundu, lapho kufakwa i-iron powder eningi, umbala uba mnyama, i-iron powder uma ingaphezu kwenani elithile ngesikhathi esithile yaziwa nangokuthi i-polyaluminum-iron chloride, ekwelapheni indle inomphumela omuhle kakhulu.
