Izinkinga zegwebu ekwelashweni kwamanzi!

Ukwelashwa kwamanzi kuyisici esibalulekile ekukhiqizweni kwezimboni zesimanje. Kodwa-ke, inkinga yegwebu ngokuvamile iba yisici esibalulekile ekuvimbeleni ukusebenza kahle kanye nekhwalithi yokwelashwa kwamanzi. Lapho umnyango wokuvikela imvelo uthola igwebu eliningi futhi ungahlangabezani nezinga lokukhishwa, ukukhishwa okuqondile akugcini nje ukubambezela inqubo, kodwa futhi kungase kubangele ukulimala okungenzeka emvelweni. Ukuze uxazulule le nkinga, ukusetshenziswa kwe-defoamer kubaluleke kakhulu.

Izingozi Zegwebu

Igwebu elichichimayo elichichima ebusweni besikhungo sokwelapha alithinti nje kuphela ukusebenza okuvamile kwesikhungo, kodwa futhi lingabangela ukungcoliswa kwendawo ezungezile. Ngokusebenzisa ama-defoamers, igwebu lingalawulwa ngokuphumelelayo ukuze kuvikelwe ukuhlanzeka nokuphepha kwemvelo.

Ukunqwabelana kwegwebu ngesikhathi sokufakwa komoya noma umoya-mpilo ekwelapheni kwamanzi ebhayoloji kungaphazamisa ukuqhubeka kokwelashwa futhi kuholele nasekulahlekeni kodaka olucushiwe namagciwane. Ukusetshenziswa kwama-defoamers kunganciphisa ukukhiqizwa kwegwebu futhi kuqinisekise inqubekelaphambili eshelelayo yenqubo yokwelashwa kwamanzi ebhayoloji.

Igwebu eliningi emanzini ajikelezayo alithinti nje kuphela ukusetshenziswa kwamanzi okwesibili, kodwa lingase libe nomthelela oqondile ekuqhubekeleni phambili kokukhiqiza kanye nekhwalithi yomkhiqizo. Ukusetshenziswa kwama-defoamers kunganciphisa igwebu emanzini ajikelezayo, kuqinisekise izinga lamanzi nokusebenza kahle kokukhiqiza.

Indlela yokukhetha i-defoamer

Umgomo wesenzo se-defoamers ngokuyinhloko ngokusebenzisana kwamakhemikhali ne-surfactant ku-foam, okubuye kunciphise umsebenzi we-surfactant, ukuze kuthuthukiswe ukuphuka kwegwebu. Eqinisweni, amanye ama-defoamers angase aguqule isakhiwo se-foam noma anciphise ukuzinza kwegwebu ukuze kuzuzwe umphumela wokukhipha amagwebu. I-Defoamers ngokungangabazeki iyisixazululo esihle lapho ibhekene nenani elikhulu lezinkinga zegwebu.

Lapho ukhetha i-ejenti ye-antifoam, udinga futhi ukunaka umphumela wayo. Amanye ama-defoamers angase abe nezinkinga ze-foam ezingaphelele noma zesibili zegwebu, ezingakwazi nje ukuxazulula inkinga yegwebu, kodwa futhi zingase zethule izinkinga ezintsha. Kufanele kuqashelwe ukuthi amanye ama-defoamers angase abe yingozi kubhaktheriya webhayoloji, athinte uhlelo lwe-MBR, futhi acekele phansi ulwelwesi lwe-percolation futhi avimbe ulwelwesi lwe-ultrafiltration. Ngemuva kokwengeza i-defoamer, udinga futhi ukunaka umphumela wayo ezinkomba zekhwalithi yamanzi, njengenani le-pH, ingqikithi ye-organic carbon, njll. Uma lezi zinkomba zidlula izinga, zingase ziqalise ukungcoliswa kwesibili futhi zithinte umphumela wokwelashwa kwamanzi. .Uma ukhetha i-agent ye-antifoam, udinga ukuqinisekisa ukuthi ngeke ibangele umonakalo ohlelweni lokuhlanza amanzi. Ngakho-ke, izindleko nokulula kokusebenza nakho kuyizici okufanele zicatshangelwe lapho kukhethwa ama-defoamers.

Uma usenokungabaza ngokukhethwa kwe-defoamer. Noma ufuna ukuthenga ama-defoams namanye amakhemikhali okuhlanza amanzi. Ngicela ungithinte.
