Izinto ezahlukeneyo ze-membrane zisetyenziswa kushishino lonyango lwamanzi, kwaye ezona zixhaphakileyo ziinwebu ze-ultrafiltration kunye ne-reverse osmosis membranes.Zombini ii-membrane ze-ultrafiltration kunye ne-reverse osmosis membranes ziyinto esetyenziswayo kwisixhobo sokunyanga amanzi.Ubungakanani bepore ye-reverse osmosis inwebu yi-1/100 kuphela yaleyo ye-ultrafiltration inwebu, ngoko ke i-osmosis yokubuyisela i-osmosis Isixhobo sonyango lwamanzi sinokususa ngokufanelekileyo isinyithi esinzima, izibulali-zinambuzane, i-chloroform, kunye nezinye izinto ezingcolisa iikhemikhali kumgangatho wamanzi.Izicoci zamanzi zeUltrafitration azinamandla.Isicoci samanzi se-ultrafiltration sinokususa izinto ezingcolisa iintsholongwane kunye neebhaktheriya, ezinokususwa nge-osmosis ebuyela umva.
1. Umahluko kwiipropati phakathi kwe-membrane ye-ultrafiltration kunye ne-reverse osmosis membrane:
I-reverse osmosis inwebu yinwebu eyenziweyo eye-semi-permeable eneempawu ezithile ezenziwe ngokulinganisa inwebu ye-biological semi-permeable.Ngokuqhelekileyo zenziwe ngezinto zepolymer.Ububanzi be-membrane pores ngokubanzi phakathi kwe-0.5 kunye ne-10 nm, kwaye ukunyanzeliswa kuhambelana nesakhiwo sekhemikhali senwebu ngokwayo.
I-membrane ye-Ultrafiltration luhlobo lwe-membrane ye-microporous filtration ene-pore yokulinganisa ubungakanani obufanayo kunye nobukhulu obulinganisiweyo be-pore ububanzi be-0.001-0.02 microns.Ukusebenzisa uxinzelelo olufanelekileyo kwelinye icala le-membrane kunokukhusela iimolekyuli ze-solute ezincinci kunobukhulu be-pore ukuze zihlukanise iinqununu ezinobunzima be-molecular obukhulu kune-500 Daltons (iiyunithi ze-atomic mass) kunye nobukhulu be-particle enkulu kune-nanometers ezili-10.I-membrane ye-ultrafiltration yenye ye-membrane yokuqala yokwahlula i-polymer eyaphuhliswayo, kunye nesixhobo sokucoca i-ultrafiltration senziwe kwimizi-mveliso kwi-1960s.
2. Izinto eziluncedo kunye nokungalunganga kwe-ultrafiltration membrane kunye ne-reverse osmosis membrane:
Iinzuzo ze-ultrafiltration: ngokuqhelekileyo akukho iimpompo, akukho kusetyenziswa kwamandla, akukho ngxaki yokhuseleko lombane;amalungu ambalwa, uxinzelelo lwamanzi aphantsi, izinga lokusilela okuphantsi ngokwentelekiso, kunye namathuba okuvuza kwamanzi;isakhiwo esilula kunye nexabiso eliphantsi;
Ukungalungi: isiphumo esibi sokususa ukungcola kweekhemikhali emanzini;isiphumo esibi kwiziganeko ezikhethekileyo zonikezelo lwamanzi;incasa embi kancinane yamanzi;ayikwazi ukunciphisa ubulukhuni bamanzi, obufana nobunzima obuphezulu bamanzi epompo, isikhongozeli samanzi abilayo sinokungcoliswa.
I-membrane ye-Ultrafiltration inokususa i-macromolecules, i-colloids, iiprotheni, iinqununu, njl njl kwisisombululo, kwaye ineempawu zoxinzelelo oluphantsi, ukuveliswa kwamanzi amakhulu, kunye nokusebenza lula.Ngokuvavanya isiphumo sonyango lwesixhobo sombhobho we-fiber ultrafiltration inwebu yokuhlanjululwa nzulu kwamanzi, kubonakaliswe ukuba isixhobo sokucoca amanzi se-ultrafiltration sinokuphelisa ngokufanelekileyo ungcoliseko lwesibini lwamanzi kuthungelwano lombhobho kunye nokuphucula ngakumbi umgangatho wamanzi.
Iingenelo ze-reverse osmosis izixhobo zokunyanga amanzi: umgangatho wamanzi akhuselekileyo, unokususa ngokufanelekileyo zonke iintlobo zokungcola okuyingozi kumgangatho wamanzi;isiphumo esingcono kwiziganeko ezikhethekileyo zonikezelo lwamanzi;incasa engcono yamanzi;inokunciphisa ngokufanelekileyo ubunzima bomgangatho wamanzi, kwaye isitya samanzi abilayo akulula ukusikala;
Ukungalungi: iimpompo, ukusetyenziswa kwamandla, imiba yokhuseleko lombane;amalungu amaninzi, uxinzelelo lwamanzi oluphezulu, izinga eliphezulu lokungaphumeleli, kunye nokuba nokwenzeka kokuvuza kwamanzi;isakhiwo esinzima, kunye nexabiso elibiza kakhulu.
3. Uluhlu lwesicelo se-membrane ye-ultrafiltration kunye ne-reverse osmosis membrane:
Uluhlu lwesicelo se-reverse osmosis inwebu
Umbane, i-petrochemical, intsimbi kunye nentsimbi, i-electronics, amayeza, ukutya kunye nesiselo, ulawulo lukamasipala kunye nokukhuselwa kokusingqongileyo kunye namanye amasimi, kwi-desalination yamanzi olwandle kunye namanzi amtyuba, amanzi e-boiler feed, amanzi acocekileyo amashishini kunye nebakala lombane lokulungiswa kwamanzi ahlambulukileyo, ukusela imveliso yamanzi acocekileyo, unyango lwamanzi amdaka kunye nenkqubo yokwahlula ekhethekileyo idlala indima ebalulekileyo.
Uluhlu lwesicelo se-membrane ye-ultrafiltration
Amanzi acocekileyo kunye namanzi e-ultrapure asetyenziswa njenge-reverse osmosis pretreatment kunye ne-ultrapure water terminal treatment kwinkqubo yokulungiselela;Amanzi amashishini asetyenziselwa ukwahlula iibhaktheriya, imithombo yobushushu, i-colloids, ukungcola okumisiweyo, kunye ne-macromolecular organics;amanzi okusela, ukucocwa kwamanzi amaminerali;ukuvubela, ishishini lokulungiselela i-Enzyme kunye noxinaniso lweshishini lamayeza, ukucocwa, kunye nokucaciswa;ukugxininiswa kwejusi kunye nokwahlula;iimbotyi zesoya, imveliso yobisi, ishishini leswekile, iwayini, ijusi yeti, iviniga, njl njl, ukwahlula, ukugxila kunye nokucaciswa;Amanzi amdaka akwimizi-mveliso kunye nokucocwa nokuhlanjululwa kwelindle lasekhaya;Ukubuyiswa kwepeyinti ye-electrophoretic.
