Ukufaka amanzi angcolile ukuze aphinde asetshenziswe noma alahlwe - ikakhulukazi lawo angcoliswe amakhemikhali, uwoyela, amagrisi, noma izinto ezifakwe emulsified - kungaba nzima kakhulu mayelana nokusebenza kahle kanye nezindleko. Ngokujabulisayo, ama-membrane amasha okuhlunga okuthuthukile abhekana nalezi zinselele. Nakhu ukuthi ochwepheshe bezimboni zokwelashwa kwamanzi bazuza kanjani kubuchwepheshe obusha be-Anti-Fouling ekukhiqizeni ulwelwesi lwe-RO.
Imvelo yalezi zingqimba ezilwa nokungcolisa ezinelungelo lobunikazi ngomunye wemehluko wazo obalulekile. Ulwelwesi oluyinhlanganisela lwesisekelo luhlanganisa i-porosity engu-75%, i-hydrophobic polymer matrix exosha amanzi, kanye ne-hydrophilic inorganic filler edonsa amanzi ngolwelwesi, ehlinzeka ngamandla e-capillary ahlinzeka ngokuguquguquka okukhulu kunolwelwesi oluvamile lwe-hydrophobic. Lawa ma-membrane ayisisekelo acutshungulwa kamuva ukuze akhe ama-membrane angama-super hydrophilic, akhulisa ukumelana nokungcola ngamafutha nezinye izinto ze-viscous nakakhulu.
Lawa ma-membrane angase abuyele emuva ngaphandle kokukhathazeka ngokuqhekeka njengoba into eyinhlanganisela iwungqimba olulodwa kunokuba ibe ungqimba oluncane olusansimbi phezu kokusekelwa kwesakhiwo kosayizi omkhulu wembotshana. Ukugeza ingemuva kunikeza ezinye izinqubo zokuhlanza, ezinganciphisa ukungcoliswa futhi andise impilo yolwelwesi. Ama-anti-fouling kanye nenhlanganisela yezimpawu ze-hydrophobic/hydrophilic ahlinzeka ngokusebenza okuphezulu ngenkathi andisa impilo yokuhlanza i-backflush. Le nhlanganisela yezici ifanele izinhlelo zokusebenza zokuhlunga ezenziwe inkimbinkimbi ngamakhemikhali, uwoyela, amagrisi, nezinto ezihlukile ze-emulsified.
Izinzuzo zobuchwepheshe bolwelwesi olunqanda ukungcoliswa zifaka ukuthuthukiswa kokusebenza okusobala kanye nomnotho okhuphukile, okuwenza afanelekele izinhlelo eziningi ezahlukene. Lokhu kufaka phakathi ukuhlukaniswa kwamafutha/amafutha/amanzi, kanye nezinhlelo zokusebenza zokwelashwa kwangaphambili kwe-reverse-osmosis (RO). Cabangela lezi zinzuzo ezilandelayo
Amanani aphezulu we-Flux.
Uma kuqhathaniswa nangaphambili, imiklamo ye-membrane evamile, lawa ma-membrane anoveli anoveli ahlinzeka ngokuhlukana okusebenzayo kanye namazinga aphezulu okuguquguquka (Umfanekiso 3) ngezingcindezi ezifanayo noma eziphansi zokusebenzisa kabusha amanzi noma ukukhishwa kwamanzi ahlanzekile. Angase futhi athole amafutha aphinde asetshenziswa futhi amafutha kunezindlela ezivamile zokuhlunga.
Ukungcoliswa Okuncishisiwe
Kunoma yiluphi uhlelo lokusebenza, ikhono lokusebenzisa ulwelwesi ekucindezelweni okuphansi kwe-transmembrane lisiza ekwehliseni ukonakala. Ama-anti-fouling membranes adalwe ukuze abhekane namanzi okunzima ukuwaphatha lapho amanye ama-membrane avamile ayengcolisa ngokushesha, agcine ulwelwesi luhlanzekile futhi lwelule ukuphila kwalo.
Ikhwalithi Ye-Permeate Eyingqayizivele
Ukusatshalaliswa kosayizi wembotshana ophelele kwalolu lwelwesi olulwa nokungcoliswa kwenza kube lula ukususwa okuphelele kwezinhlayiya ezimisiwe, uwoyela wamahhala, nezinto ezenziwe nge-emulsified kuze kube ngaphansi kwamazinga ayi-10 ppm. I-porosity engaguquki ibamba ukungcola okwengeziwe futhi inikeze ikhwalithi yamanzi ephezulu ku-permeate, ikakhulukazi ekusetshenzisweni kabusha kwamanzi ampunga okudayiswa okuvinjwe insipho, ama-surfactants, nenye imfucumfucu.
Ukusebenza Kwezomnotho Okuthuthukisiwe

Kwa-HID sikhiqiza ulwelwesi lwezimboni lwe-AF lwamamodeli angu-4040 no-8040. I-BW-4040-AF futhi I-BW-8040-AF
