Ukuhlolwa Kwemininingwane Eyinhloko Ye-PolyDADMAC
Okuqukethwe okusebenzayo, okubizwa nangokuthi okuqukethwe okuqinile, kumelela iphesenti le-polymer ye-PolyDADMAC esebenzayo kusisombululo se-coagulant. Emakethe yokwelapha amanzi yomhlaba wonke, ama-coagulant e-PDADMAC avame ukuhlinzekwa ngokuqukethwe okusebenzayo okusukela ku-10% kuya ku-40%, kanti ama-20%, 30%, kanye no-40% ayizinhlobo ezithandwa kakhulu kwezentengiselwano.
Kusukela ekusebenzeni kanye nombono wezindleko, okuqukethwe okusebenzayo kungenye yezindlela zokuqala umthengi okufanele aziqinisekise ngeumhlinzeki we-coagulant.
Kungani Okuqukethwe Okuqinile kwe-PolyDADMAC Kubalulekile?
Okuqukethwe okuphezulu okusebenzayo kusho ukuthi i-coagulant esebenza kahle kakhulu ilethwa ngevolumu ngayinye. Lokhu kuthinta ngqo:
Ukusebenza kahle komthamo:Izinto eziqinile eziphakeme zidinga inani eliphansi lomthamo ukuze kube nomphumela ofanayo wokwelashwa
