Indlela Yokukhetha I-Polyaluminum Chloride Ekwelashweni Kwamanzi

Iyini i-polyaluminum chloride?

I-Polyaluminum Chloride (i-Poly aluminium chloride) ayinayo i-PAC. Iwuhlobo lwekhemikhali yokwelapha amanzi emanzini okuphuza, amanzi ezimboni, amanzi angcolile, ukuhlanzwa kwamanzi angaphansi komhlaba ukuze kususwe umbala, kususwe i-COD, njll. ngokusabela. Ingabhekwa njengohlobo lwe-flocculate agent, i-decolor agent noma i-coagulant.

I-PAC iyi-polymers engaphili encibilika emanzini phakathi kwe-ALCL3 ne-AL(OH) 3, ifomula yamakhemikhali ingu-[AL2(OH)NCL6-NLm], 'm' ibhekisela ezingeni le-polymerization, 'n' imele izinga elingathathi hlangothi lemikhiqizo ye-PAC.lt inezinzuzo zokusetshenziswa okungabizi kakhulu, kanye nomphumela omuhle kakhulu wokuhlanza.

Zingaki izinhlobo ze-PAC?

Kunezindlela ezimbili zokukhiqiza: enye iwukomisa izigubhu, enye iwukomisa ngokufutha. Ngenxa yomugqa wokukhiqiza ohlukile, kunomehluko omncane kokubili ekubukekeni nasekuqukeni.

I-PAC yokomisa izigubhu ingama-granule aphuzi noma aphuzi amnyama, anokuqukethwe kwe-Al203 kusuka ku-27% kuya ku-30%. Izinto ezingancibiliki emanzini azidluli ku-1%.

Nakuba i-Spray Drying PAC iphuzi, inombala ophuzi okhanyayo noma omhlophe, okuqukethwe yi-AI203 kusuka ku-28% kuya ku-32%. Izinto ezingancibiliki emanzini azidluli ku-0.5%.

Ungayikhetha kanjani i-PAC efanele yokwelashwa kwamanzi okuhlukile?

Akukho ncazelo yokusetshenziswa kwe-PAC ekwelashweni ngamanzi. Kuyindinganiso ye-PAC kuphela edinga ukulungiswa kwamanzi ngaphandle kokukhetha. Inombolo Ejwayelekile yokwelashwa kwamanzi okuphuza yi-GB 15892-2009. Ngokuvamile, i-27-28% PAC isetshenziswa ekwelashweni kwamanzi angaphuzwayo, kanti i-29-32% PAC isetshenziswa ekwelashweni kwamanzi okuphuza.
