Ukungaqondani okuqhelekileyo xa ukhetha i-pam

I-polyacybuslam. Nangona kunjalo, uninzi lwabasebenzisi luye lwangena ngokungaqondani ngexesha lokhetho kunye nokusebenzisa inkqubo. Eli nqaku lijolise ekuvezeni ezi ntsikisweni kwaye zinike ukuqonda okuchanekileyo kunye neengcebiso.

Ukungaqondi 1: Ukukhulula ubunzima bemolekyuli, ukuphakama kokufanelekileyo.

Xa ukhetha iPolycactrylamide, abantu abaninzi bacinga ukuba imodeli enobunzima obukhulu kwimolekyuli kufuneka ibenayo impumelelo. Kodwa enyanisweni, kukho amakhulu eemodeli zePolyacrylamide, ezilungele iimeko ezahlukeneyo zomgangatho wamanzi. Uhlobo lwamanzi amdaka aveliswa ziifektri kumashishini ahlukeneyo yahlukile. Ixabiso le-pH kunye nokungcola okukhethekileyo kweempawu ezahlukeneyo zamanzi ahlukile kakhulu. Basenokuba bacidi, i-alkaline, abangathathi hlangothi, okanye iqula leoyile, into ephilayo, umbala, i-sediment, njl njl ke kunzima ukuba ihlangane zonke iimfuno zonyango lwamanzi amdaka. Inkqubo echanekileyo kukhetho lokuqala ukukhetha imodeli ngovavanyo, kwaye emva koko wenze uvavanyo lomatshini ukufumanisa i-dosage efanelekileyo yokufezekisa eyona mpembelelo ineendleko.

Ukungaqondi 2: Ukuphakamisa uxinzelelo loqwalaselo, olungcono

Xa belungiselela izisombululo, abasebenzisi abaninzi bakholelwa ukuba ngaphezulu koxinzelelo, engcono iipropathi zokubhalwa. Nangona kunjalo, olu luvo aluchanekanga. Ngapha koko, ukugxininiswa koqwalaselo lwe-PAM kufuneka kumiselwa ngokwemigaqo ethile yokuntywila kunye ne-sludge. Ngokubanzi, izisombululo ze-PAM ngokuxinezeleka kwi-0.1% -0.3% zilungele ukubhalwa kunye nokuhamba kwexesha, ngelixa uxinzelelo lwe-Sludge Dewaters ngu-0 kunye ne-Sludge Medicanting yi-0.2% -0.5%. Xa zininzi kakhulu ukungcola kwi-loure, ukugxininiswa kwe-pam kunokufuneka kukwanda ngokufanelekileyo. Ke ngoko, ugxininiso loqwalaselo olusengqiqweni kufuneka lugqitywe ngovavanyo ngaphambi kokusebenzisa ukuqinisekisa ukuba lolona mpembelelo lusetyenziswayo.

Ukungaqondi 3: Ixesha elide ukunyibilika kunye nexesha elifanelekileyo, elingcono

I-Polyacrylamyel yi-therstalline emhlophe ye-crystalline ekufuneka ichithwe ngokupheleleyo ekufezekiseni okona kulungileyo. Abasebenzisi abaninzi bacinga ukuba ixesha elide lokunyibilikisa kunye nexesha lokuchitha, kodwa eneneni akunjalo. Ukuba ixesha elitshatileyo lide kakhulu, liya kubangela ukophuka kwinxalenye ye-PAM Molecular kwaye ichaphazele ukusebenza kwenkqubo. Ngokubanzi, ixesha lokuthintela kunye nesokolayo akufuneki libe ngaphantsi kwemizuzu engama-30 kwaye kufuneka lundiswe ngokufanelekileyo xa iqondo lobushushu liphantsi ebusika. Ukuba ixesha lokupheliswa kunye nexesha elitshatileyo lifutshane kakhulu, i-PAM ayizukuphoswa ngokupheleleyo, eya kukhokelela ekungakwazi ukwenza isitya esikhawulezayo. Ke ngoko, abasebenzisi kufuneka baqinisekise ukuchithwa okwaneleyo kunye nexesha eliqinisekileyo xa beyisebenzisa ukuqinisekisa ukuba isiphumo se-pam.

Ukungaqondi kwi-4: I-IONICIRY / I-IONIC yesiqhelo sisiseko sokhetho

Njengomnye wezalathiso ezibalulekileyo zePolyacrysamide, i-Ingocys ibhekisa kwi-ntlawulo ye-Ionic engalunganga nefanelekileyo ye-ionic kunye noxinaniso lwayo. Abantu abaninzi banikela ingqalelo kakhulu kwi-ionity xa bethenga, becinga ukuba abaphezulu kakhulu. Kodwa enyanisweni, inqanaba le-ioesity lihambelana nobungakanani bobunzima bemolekyuli. Ukuphakama kwe-ionisty, incinci ubunzima bemolekyuli, kwaye ngaphezulu kwexabiso. Kwinkqubo yokhetho, ukongeza kwi-ionicty, ezinye izinto kufuneka zithathelwe ingqalelo, njengemigangatho ethile esemgangathweni, iimfuno zefuthe lokuzibhalwa, njl njl. Uvavanyo oluqhubekayo luyafuneka ukumisela imodeli efunekayo.

Njengeiflocculant, i-polyactrylam idlala indima ebalulekileyo kwishishini lonyango lwamanzi. Xa ufuna ukukhetha imigaqo elungele wena, nceda uqhagamshelane nam.
