I-PAM Flocculant: imveliso enamandla yeekhemikhali yonyango lwamanzi kwimizi-mveliso

I-Polyacrylamide(PAM) yipolymer eyenziweyo ehlala emanzini esetyenziswa kakhulu kwiinkqubo zonyango lwamanzi. Isetyenziswa kakhulu njenge-flocculant kunye ne-coagulant, i-arhente yekhemikhali ebangela ukuba amasuntswana axhonyiweyo emanzini ahlangane abe zii-floc ezinkulu, ngaloo ndlela inceda ekususweni kwawo ngokucaciswa okanye ukuhluzwa. Ngokuxhomekeke kumgangatho wamanzi amdaka, sebenzisa i-cationic, i-anionic, okanye i-non-ionic PAM. I-Polyacrylamide inikezela ngeenzuzo ezininzi kunyango lwamanzi, kubandakanya ukusebenza kwayo kuluhlu olubanzi lwe-pH, ubushushu, kunye nobubanzi be-turbidity. Isiphumo se-coagulation sinokuvavanywa kusetyenziswa uvavanyo lweJar okanye umlinganiselo we-turbidity.

I-Polyacrylamide ingasetyenziswa kakhulu kunyango lwamanzi kwimizi-mveliso, unyango lwelindle, unyango lwamanzi amdaka, njl. Kwizityalo zonyango lwamanzi, i-polyacrylamide isetyenziswa kwiinkqubo ezahlukeneyo, kubandakanya ukucaciswa kokuqala nokwesibini, ukuhluzwa, kunye nokubulala iintsholongwane. Ngexesha lenkqubo yokucaciswa kokuqala, yongezwa emanzini aluhlaza ukukhuthaza ukuhlaliswa kwezinto eziqinileyo ezixhonyiweyo, ezithi emva koko zisuswe ngokutyibilika okanye ngokudada. Kwindlela yokucaciswa yesibini, i-polyacrylamide isetyenziselwa ukucacisa ngakumbi amanzi acociweyo ngokususa izinto eziqinileyo ezisele zixhonyiwe kunye nezinto eziphilayo ezifunxwe yi-adsorbed.

Umgaqo wokusebenza wei-polyacrylamide flocculantyi: emva kokongeza isisombululo se-PAM, i-PAM iyawafunxa amasuntswana, yenze iibhulorho phakathi kwawo. Kwichibi lokuqala, inamathela ukuze yenze amasuntswana amakhulu, kwaye umzimba wamanzi uba mdaka ngeli xesha. Emva kokuba inani elikhulu lamasuntswana likhule kwaye lityebile, liya kuhamba lize litshone kancinci ngokuhamba kwexesha, kwaye umaleko ongaphezulu wamanzi aluhlaza uya kucaca. Le nkqubo yokuhlanganisana iphucula iimpawu zokuzinza kwamasuntswana, okwenza kube lula ukuwasusa ngexesha lokucacisa okanye ukuhluza. I-Polyacrylamide idla ngokusetyenziswa kunye nezinye ii-coagulants kunye nee-flocculants ukufezekisa ukucaca okufanelekileyo kunye nokusebenza kokuhluza.

I-Polyacrylamide ikwadlala indima ebalulekileyo ekuhluzeni amanzi. Idla ngokusetyenziswa njengesihluzo sangaphambi kokucoca kwiifilitha okanye kwezinye iindlela zokucoca ngokwasemzimbeni ukususa izinto eziqinileyo ezixhonyiweyo kunye nokudumba. Ngokuphucula ukususwa kwezi suntswana, i-polyacrylamide inceda ukuqinisekisa ukuba ifilitha icacile kwaye icocekile.

I-Polyacrylamide yi-polymer ezinzileyo nengenabungozi eqhekeka ngeenkqubo zendalo okanye ngeendlela zonyango lwebhayoloji. Kufuneka kuqatshelwe ukuba isisombululo esichithekileyo siya kubangela ukuba umgangatho utyibilike kakhulu, nto leyo enokubangela ukuba uwe.

Nangona kunjalo, ubungakanani be-PAM esetyenzisiweyo buxhomekeke kuhlobo lwamanzi amdaka kunye nomxholo wee-particles eziqinileyo ezixhonyiweyo, kunye nokuba khona kwezinye iikhemikhali, ii-asidi, kunye nezinto ezingcolisayo emanzini. Ezi zinto zinokuchaphazela isiphumo sokujiya kwe-PAM, ngoko ke kufuneka kwenziwe uhlengahlengiso olufanelekileyo ngexesha lokusetyenziswa. Iimveliso ze-PAM ezinobunzima obahlukeneyo beemolekyuli, ii-degrees ze-ionic, kunye needosi kufuneka zikhethwe ngononophelo kwiintlobo ezahlukeneyo zamanzi amdaka.
