Indlela yokukhetha iPolyaluminum Chloride kunyango lwamanzi

yintoni i-polyaluminum chloride?

I-Polyaluminum Chloride (i-Poly aluminium chloride) ayinayo i-PAC. Luhlobo lwekhemikhali yokucoca amanzi emanzini okusela, amanzi emizi-mveliso, amanzi amdaka, ukucoca amanzi angaphantsi komhlaba ukususa umbala, ukususa i-COD, njl.njl. Ingathathwa njengohlobo lwe-flocculate agent, i-decolor agent okanye i-coagulant.

I-PAC yi-polymers ezingaphiliyo ezinyibilikayo emanzini phakathi kwe-ALCL3 kunye ne-AL(OH) 3, ifomula yekhemikhali yi[AL2(OH)NCL6-NLm], 'm' ibhekisa kubungakanani be-polymerization, 'n' imele inqanaba elingathathi cala leemveliso ze-PAC.lt ineengenelo zexabiso eliphantsi. Ukusetyenziswa okuncinci, kunye nesiphumo esihle sokucoca.

Zingaphi iintlobo ze-PAC?

Kukho iindlela ezimbini zokuvelisa: enye kukomisa iidrama, enye kukomisa ngespray. Ngenxa yeendlela ezahlukeneyo zokuvelisa, kukho umahluko omncinci kwimbonakalo nakwizinto ezikuyo.

I-PAC yokomisa iidrama yi-granules etyheli okanye emthubi omnyama, enomxholo we-Al203 ukusuka kwi-27% ukuya kwi-30%. Izinto ezinganyibilikiyo emanzini azidluli kwi-1%.

Nangona i-Spray Drying PAC inombala otyheli, umbala otyheli okanye omhlophe, kwaye umxholo wayo yi-AI203 ukusuka kwi-28% ukuya kwi-32%. Izinto ezinganyibilikiyo emanzini azidluli kwi-0.5%.

Ungayikhetha njani i-PAC efanelekileyo yonyango lwamanzi olwahlukileyo?

Akukho nkcazelo yokusetyenziswa kwe-PAC kunyango lwamanzi. Yimfuneko yomgangatho we-PAC kuphela yonyango lwamanzi olungenamkhethe. Inombolo Esemgangathweni yonyango lwamanzi okusela yi-GB 15892-2009. Ngokwesiqhelo, i-27-28% ye-PAC isetyenziswa kunyango lwamanzi angaselwayo, kwaye i-29-32% ye-PAC isetyenziswa kunyango lwamanzi okusela.
