Zeziphi izalathisi eziphambili ekufuneka ugxile kuzo xa uthenga iPolyaluminum Chloride？

Xa uthengaI-Polyaluminum Chloride(PAC), i-coagulant esetyenziswa kakhulu kwiinkqubo zokunyanga amanzi, kufuneka kuhlolwe imiqondiso emininzi ebalulekileyo ukuqinisekisa ukuba imveliso iyahlangabezana nemigangatho efunekayo kwaye ifanelekile ukusetyenziswa kwayo. Ngezantsi kukho imiqondiso ephambili ekufuneka ijongwe kuyo:

1. Umxholo weAluminiyam

Eyona nto iphambili esebenzayo kwi-PAC yi-aluminium. Ukusebenza kwe-PAC njenge-coagulant kuxhomekeke kakhulu kuxinzelelo lwe-aluminium. Ngokwesiqhelo, umxholo we-aluminium kwi-PAC uchazwa njengepesenti ye-Al2O3. I-PAC esemgangathweni ophezulu ngokubanzi iqulethe phakathi kwe-28% ukuya kwi-30% ye-Al2O3. Umxholo we-aluminium kufuneka wanele ukuqinisekisa ukujiya okusebenzayo ngaphandle kokusetyenziswa kakhulu, okunokukhokelela ekungasebenzi kakuhle kwezoqoqosho kunye nemiphumo emibi enokubakho kumgangatho wamanzi.

2. Isiseko

I-Basicity yindlela yokulinganisa i-hydrolysis yeentlobo ze-aluminium kwi-PAC kwaye ichazwa njengepesenti. Ibonisa umlinganiselo wee-ion ze-hydroxide kwi-aluminium kwisisombululo. I-PAC enoluhlu lwe-basicity oluyi-40% ukuya kwi-90% idla ngokukhethwa kwizicelo zonyango lwamanzi. I-basicity ephezulu idla ngokuthetha ukuba i-coagulation isebenza kakuhle kodwa kufuneka ilinganiswe neemfuno ezithile zenkqubo yonyango lwamanzi ukuze kuthintelwe ukunyangwa kakhulu okanye okunganyangwa kakuhle.

4. Amanqanaba okungcola

Ubukho bezinto ezingcolisayo ezifana neentsimbi ezinzima (umz., i-lead, i-cadmium) kufuneka bube mncinci. Ezi zinto zingcolisayo zinokubangela iingozi kwimpilo kwaye zichaphazele ukusebenza kwe-PAC. I-PAC ecocekileyo kakhulu iya kuba namanqanaba aphantsi kakhulu ezo zinto zingcolisayo. Amaphepha eenkcukacha anikezelwa ngabavelisi kufuneka aquke ulwazi malunga nobuninzi obuvumelekileyo bezi zinto zingcolisayo.

6. Uhlobo (oluqinileyo okanye oluyilwelo)

I-PACifumaneka zombini kwimilo eqinileyo (umgubo okanye iigranule) kunye neyolwelo. Ukukhetha phakathi kwemilo eqinileyo neyolwelo kuxhomekeke kwiimfuno ezithile zesityalo sonyango, kubandakanya iindawo zokugcina, izixhobo zokulinganisa, kunye nokulula kokuphatha. I-Liquid PAC idla ngokuthandwa ngenxa yokuba kulula ukuyisebenzisa kunye nokunyibilika ngokukhawuleza, ngelixa i-solid PAC inokukhethwa ngenxa yokugcina ixesha elide kunye neenzuzo zokuthutha. Nangona kunjalo, ubomi beshelufu bolwelo bufutshane, ngoko akucetyiswa ukuba uthenge ulwelo ngqo ukuze ulugcine. Kucetyiswa ukuba uthenge ulwelo oluqinileyo uze ulwenze ngokwakho ngokwesilinganiso.

7. Ubomi beShelufu kunye noZinzo

Ukuzinza kwe-PAC ngokuhamba kwexesha kuchaphazela ukusebenza kwayo. I-PAC esemgangathweni ophezulu kufuneka ibe nexesha elizinzileyo lokuhlala eshelufini, igcine iipropati zayo kunye nokusebenza kwayo ixesha elide. Iimeko zokugcina, ezifana nobushushu kunye nokuvezwa emoyeni, zinokuchaphazela ukuzinza, ngoko ke i-PAC kufuneka igcinwe kwindawo epholileyo, neyomileyo kwizikhongozeli ezivaliweyo ukuze igcine umgangatho wayo.

8. Ukonga iindleko

Ukongeza kumgangatho wemveliso, kubalulekile ukuqwalasela ukusebenza kakuhle kweendleko zokuthenga. Thelekisa amaxabiso, ukupakisha, ukuthuthwa, kunye nezinye izinto zabathengisi abahlukeneyo ukuze ufumane iimveliso ezinokusetyenziswa kakuhle kweendleko.

Ngamafutshane, xa uthenga i-polyaluminum chloride, kubalulekile ukuqwalasela umxholo we-aluminiyam, ubuncinci, ixabiso le-pH, amanqanaba okungcola, ukunyibilika, uhlobo, ixesha lokuphelelwa, ukusebenza kakuhle kweendleko, kunye nokuthobela imithetho. Ezi zibonakaliso zizonke zimisela ukufaneleka nokusebenza kakuhle kwe-PAC kwiindlela ezahlukeneyo zokunyanga amanzi.
