Ukwelashwa kwamanzi kuyisici esibalulekile ekukhiqizweni kwezimboni zanamuhla. Kodwa-ke, inkinga ye-foam ivame ukuba yisici esibalulekile ekuvimbeleni ukusebenza kahle kanye nekhwalithi yokwelashwa kwamanzi. Lapho umnyango wokuvikela imvelo uthola i-foam eningi futhi ingahlangabezani nezindinganiso zokukhishwa, ukukhishwa okuqondile akugcini nje ngokubambezela inqubo, kodwa futhi kungabangela umonakalo ongaba khona emvelweni. Ukuze kuxazululwe le nkinga, ukusetshenziswa kwe-defoamer kubaluleke kakhulu.
Izingozi Ze-Foam
Ukugcwala kwegwebu ngokweqile kusuka ebusweni besikhungo sokwelapha akuthinti nje kuphela ukusebenza okuvamile kwesikhungo, kodwa futhi kungabangela ukungcola endaweni ezungezile. Ngokusebenzisa ama-defoamer, igwebu lingalawulwa ngempumelelo ukuze kuvikelwe ukuhlanzeka nokuphepha kwendawo ezungezile.
Ukuqongelela kwegwebu ngesikhathi sokungenisa umoya noma i-oxygen ekuphathweni kwamanzi ngezinto eziphilayo kungaphazamisa inqubekela phambili yokwelashwa futhi kuholele nasekulahlekelweni kodaka olusebenzayo kanye namagciwane. Ukusetshenziswa kwama-defoamer kunganciphisa ukukhiqizwa kwegwebu futhi kuqinisekise inqubekela phambili ebushelelezi yenqubo yokwelashwa kwamanzi ngezinto eziphilayo.
Igwebu eliningi emanzini ajikelezayo alithinti nje kuphela ukusetshenziswa kwesibili kwamanzi, kodwa futhi lingaba nomthelela oqondile enqubweni yokukhiqiza kanye nekhwalithi yomkhiqizo. Ukusetshenziswa kwama-defoamer kunganciphisa igwebu emanzini ajikelezayo, kuqinisekiswe ikhwalithi yamanzi kanye nokusebenza kahle kokukhiqiza.
Indlela yokukhetha i-defoamer
Isimiso sokusebenza kwama-defoamers sisebenza kakhulu ngokusebenzisana kwamakhemikhali ne-surfactant efomini, okunciphisa umsebenzi we-surfactant, ukuze kukhuthazwe ukuqhekeka kwefomini. Eqinisweni, amanye ama-defoamers angashintsha nesakhiwo sobuso befomini noma anciphise ukuzinza kwefomini ukuze kufezwe umphumela wokususa ifomini. Ama-defoamers ngokungangabazeki ayisisombululo esihle lapho ebhekene nezinkinga eziningi zefomini.
Uma ukhetha i-antifoam agent, udinga futhi ukunaka umphumela wayo. Amanye ama-defoam angaba nezinkinga zokungapheleli kokuhlanza noma ze-foam yesibili, ezingakwazi nje ukuxazulula inkinga ye-foam, kodwa futhi ezingaletha izinkinga ezintsha. Kufanele kuqashelwe ukuthi amanye ama-defoam agent angaba yingozi kumabhaktheriya ebhayoloji, athinte uhlelo lwe-MBR, futhi abhubhise ngisho ne-percolation membrane futhi avimbele i-ultrafiltration membrane. Ngemva kokufaka i-defoam agent, udinga futhi ukunaka umphumela wayo ezinkombeni zekhwalithi yamanzi, njengenani le-pH, i-carbon e-organic iyonke, njll. Uma lezi zinkomba zidlula izinga, zingabangela ukungcola kwesibili futhi zithinte umphumela wokwelashwa kwamanzi. .Uma ukhetha i-antifoam agent, udinga ukuqinisekisa ukuthi ngeke ibangele umonakalo ohlelweni lokwelapha amanzi. Ngakho-ke, izindleko kanye nokulula kokusebenza nakho kuyizinto okufanele zicatshangelwe lapho ukhetha ama-defoam agent.
Uma usenokungabaza ngokukhethwa kwe-defoamer. Noma ufuna ukuthenga ama-defoamer namanye amakhemikhali okwelapha amanzi. Ngicela ungithinte.
