Zinthu zosiyanasiyana za membrane zimagwiritsidwa ntchito popangira madzi, ndipo zodziwika bwino ndi ma ultrafiltration membranes ndi reverse osmosis nembanemba.Ma nembanemba a ultrafiltration ndi nembanemba ya reverse osmosis ndizomwe zimagwiritsidwa ntchito pazida zochizira madzi.Kukula kwa pore kwa nembanemba ya reverse osmosis ndi 1/100 yokha ya nembanemba ya ultrafiltration, kotero reverse osmosis Zida zochizira madzi zimatha kuchotsa zitsulo zolemera, mankhwala ophera tizilombo, chloroform, ndi zoipitsa zina zamadzi mumtundu wamadzi.Ultrafiltration oyeretsa madzi alibe mphamvu.The ultrafiltration water purifier imatha kuchotsa tinthu tating'ono toyambitsa matenda komanso mabakiteriya, omwe amatha kuchotsedwa ndi reverse osmosis.
1. Kusiyana kwa zinthu pakati pa ultrafiltration nembanemba ndi reverse osmosis nembanemba:
Reverse osmosis nembanemba ndi nembanemba yopangira semi-permeable yokhala ndi mawonekedwe ena omwe amapangidwa potengera nembanemba ya biological semi-permeable.Nthawi zambiri zopangidwa ndi polima.Kutalika kwa ma pores a nembanemba nthawi zambiri kumakhala pakati pa 0.5 ndi 10 nm, ndipo kuthekera kwake kumagwirizana ndi kapangidwe kake ka nembanemba komwe.
Ultrafiltration nembanemba ndi mtundu wa microporous kusefera nembanemba yemweyo wa pore makulidwe ndi ovotera pore kukula osiyanasiyana ma microns 0.001-0.02.Kugwiritsa ntchito kukakamiza koyenera kumbali imodzi ya nembanemba kumatha kutulutsa mamolekyu ang'onoang'ono kuposa kukula kwa pore kuti asiyanitse tinthu tating'onoting'ono tomwe timalemera kuposa ma Daltons 500 (mayunitsi a atomiki) ndi kukula kwa tinthu kopitilira ma nanometer 10.Nembanemba ya ultrafiltration ndi imodzi mwazinthu zoyambira zolekanitsa za polima zomwe zidapangidwa, ndipo chida chopangira ultrafiltration chidapangidwa m'ma 1960s.
2. Ubwino ndi kuipa kwa ultrafiltration nembanemba ndi reverse osmosis nembanemba:
Ubwino wa ultrafiltration: nthawi zambiri palibe mapampu, osagwiritsa ntchito mphamvu, palibe zovuta zachitetezo chamagetsi;zolumikizira zochepa, kuthamanga kwamadzi pang'ono, kulephera kwamphamvu pang'ono, komanso kutha kwa madzi kutuluka;kapangidwe kosavuta ndi mtengo wotsika;
kuipa: osauka zotsatira kuchotsa mankhwala oipitsa m'madzi;zotsatira zoyipa pazochitika zapadera za kaperekedwe ka madzi;kusakoma pang'ono kwa madzi;osatha kuchepetsa kuuma kwa madzi, monga kuuma kwakukulu kwa madzi apampopi, chidebe chamadzi otentha chikhoza kuipitsidwa.
Ultrafiltration nembanemba akhoza kuchotsa macromolecules, colloids, mapuloteni, particles, etc. mu njira, ndipo ali ndi makhalidwe a low pressure, lalikulu madzi kupanga, ndi ntchito yosavuta.Ndi kuyesa zotsatira za mankhwala a dzenje CHIKWANGWANI ultrafiltration nembanemba chipangizo kwa kuyeretsedwa kwambiri madzi, izo zatsimikiziridwa kuti ultrafiltration nembanemba madzi kuyeretsedwa chipangizo angathe kuthetsa kuipitsidwa yachiwiri madzi mu maukonde chitoliro ndi kupititsa patsogolo khalidwe la madzi.
Ubwino wa zida zochizira madzi osmosis: madzi otetezeka, amatha kuchotsa zonyansa zamtundu uliwonse mumadzi;zotsatira zabwino pa zochitika zapadera za kuperekedwa kwa madzi;kukoma kwabwino kwa madzi;amatha kuchepetsa kuuma kwa madzi abwino, ndipo chidebe chamadzi otentha sichiri chophweka;
Zoipa: mapampu, kugwiritsa ntchito mphamvu, nkhani zotetezera magetsi;mafupa ambiri, kuthamanga kwa madzi, kulephera kwakukulu, komanso kutha kwa madzi;kapangidwe kovuta, ndi mtengo wokwera mtengo.
3. Ntchito zosiyanasiyana za ultrafiltration nembanemba ndi reverse osmosis nembanemba:
Kugwiritsa ntchito kwa nembanemba ya reverse osmosis
Magetsi, petrochemical, chitsulo ndi zitsulo, zamagetsi, mankhwala, chakudya ndi chakumwa, ulamuliro tauni ndi kuteteza zachilengedwe ndi madera ena, mu desalination madzi a m'nyanja ndi brackish madzi, boiler chakudya madzi, mafakitale madzi oyera ndi kalasi yamagetsi kopitilira muyeso-woyera madzi kukonzekera, kumwa madzi oyera kupanga, kuthira madzi onyansa komanso Njira yolekanitsa yapadera imakhala ndi gawo lofunikira.
Kugwiritsa ntchito kwa nembanemba ya ultrafiltration
Madzi oyera ndi madzi a ultrapure amagwiritsidwa ntchito ngati reverse osmosis pretreatment ndi ultrapure water terminal treatment pokonzekera;madzi mafakitale ntchito kulekanitsa mabakiteriya, magwero kutentha, colloids, inaimitsidwa zonyansa, ndi macromolecular organics;madzi akumwa, kuyeretsa madzi amchere;nayonso mphamvu, enzyme kukonzekera makampani ndi ndende makampani mankhwala, kuyeretsedwa, ndi kumveka;ndende ya madzi ndi kupatukana;soya, mkaka, makampani shuga, vinyo, tiyi madzi, viniga, etc. kulekana, ndende ndi kumveka;madzi otayira m'mafakitale ndi kuyeretsa zimbudzi zapakhomo ndi kuchira;Kubwezeretsa utoto wa electrophoretic.
Mwakonzeka kudziwa zambiri?Lumikizanani nafe lero kuti mupeze mtengo waulere!
