Unyango lwamanzi amdaka emigodini yenye yezona zinto zinzima kakhulu kulawulo lwamanzi kwimizi-mveliso.I-Polyacrylamide(PAM), njengesixhobo sokufunxa amanzi esisebenza kakuhle kakhulu, sidlala indima ebalulekileyo ekunyangweni kwamanzi amdaka. Nangona kunjalo, ayizizo zonke iimveliso zePAM ezifanelekileyo ekunyangweni kwamanzi amdaka. Ukukhetha uhlobo olufanelekileyo, ubunzima beemolekyuli, ubuninzi betshaja, kunye nendlela yokusebenzisa kuchaphazela ngokuthe ngqo ukusebenza kakuhle konyango, ukusebenza kakuhle kweendleko, kunye nokuthobela imigangatho yokukhupha amanzi amdaka.
Eli nqaku liza kuchaza indlela yokukhetha imveliso ye-PAM efanelekileyo kwiimfuno zonyango lwamanzi amdaka emigodini, lijolise ekuncedeni iinjineli, amaqela okuthenga, kunye nabaqhubi bezityalo ekwenzeni izigqibo ezinolwazi.
Ukuqonda Iimpawu Zamanzi Amdaka Emigodini
Amanzi amdaka okumba adla ngokuba noxinzelelo olukhulu lwezinto eziqinileyo ezixhonyiweyo, iintsimbi ezinzima, amasuntswana amancinci, kunye neentsalela zeekhemikhali. Ukuqonda iimpawu zamanzi amdaka okumba kubalulekile ngaphambi kokukhetha i-PAM. Imisebenzi eyahlukeneyo yokumba ivelisa iintlobo ezahlukeneyo zamanzi amdaka:
Imithombo Eqhelekileyo Yokwembiwa Kwamanzi Amdaka
- ▶ Ukwembiwa kwamalahle kunye nokuhlamba impahla
