Kev kho dej feem ntau yog qhov muaj qhov txawv txav; qhov sib txawv siab; tshuaj lom neeg txoj kev, membrane filtration yog kev siv cov tshuaj molecular dialysis lub hauv paus ntawm lub lim; sib cais; concentration; huv huv. Lub cev tsis muaj zog, tsis muaj kev hloov pauv, tsis muaj cov theem nrab residue thiab reactant tsim. Feem ntau yog siv lim membrane, raws li qhov tseeb ntawm: microfiltration; ultrafiltration; nanofiltration; rov qab osmosis.
Ua ntej, cov dej kho nruab nrab thiab txoj kev:
Quartz xuab zeb: tshem cov khoob khoob loj tshem tawm
PP paj rwb (polypropylene): lim xeb. Impurities. Tshem tawm me me.
Cov pa roj carbon dioxide (cov plhaub npog plhuav): adsorption ntawm cov xim hauv cov xim txawv, xws li chlorine thiab nws cov khoom.
Softening ion (sodium ion): calcium thiab magnesium thiab lwm yam kev xiam oob qhab ion txauv, cov dej hardness ntawm ion pauv, ua si lub luag dej ntawm cov dej uas muag muag.
Ultrafiltration (UF): Tshem tawm cov colloid hauv dej. Cov kab mob. Microorganisms, lub turbidity ntawm dej thiab sterilization.
Nanofiltration (NF): tshem cov calcium thiab magnesium ions, qhov degradation ntawm dej hardness.
Rov qab osmosis (RO): degradation ntsev hauv dej.
Mixed txaj (cation thiab cation pauv): tshem tawm cov yaj cov ntsev.
Electrodialysis (Yin thiab yang zaj duab xis + ionization): cov dej concentrated, tshem yin thiab yaj.
EDI (electrodialysis + ion txauv): tshem tawm cov ntsev, kom tau high-precision dej ntshiab.
Flocculation (ntxiv rau tshuaj): muaj peev xwm tshem tawm cov xim, cov khoom ntawm colloidal tshuaj, tsim ntawm cov nag lossis daus.
Dej nag (ntxiv tshuaj): degrade turbidity thiab clarify water.
Cov pa tawg: qhov tso tawm ntau ntawm cov dej ua kom tsis muaj zog hauv av los tiv thaiv nws kev koom tes hauv kev sib txuam, cuam tshuam txog dej zoo.
Biochemical txoj kev: kab lis kev cai ntawm cov kab mob ntawm cov kab mob.
Qhov ob, txheej txheem dej kho
Cov txheej txheem dej kho tiav muaj peb ntu: kev ua tiav, kev ua haujlwm ua tiav thiab kev xa tom qab.
Ua Ntej Ua Ntej: Tshem tawm cov khib nyiab thiab cov khoom loj loj, txo cov turbidity thiab xim ntawm cov dej haus. Xws li cov ntxaij lim dej (quartz xuab zeb), adsorption cov ntxaij lim dej (tshuab ua kom muaj roj) thiab cov xim lim dej (PP paj rwb).
Core treatment: Tshem tawm cov microbes. Cov kab mob. Tus kab mob. Colloids. Macromolecular tshuaj, xws li ultrafiltration system (UF)
Kev kho tom qab: dej kom zoo thiab cov kab me me, ua kom muaj dej purity dej dua, xws li rov qab osmosis (RO), ion exchange.
Hangzhou Shuidun Technology yog tshwj xeeb ntawm kev tsim thiab kev txhim kho cov dej tsis huv kho cov khoom uas muaj qhov zoo thiab resonsable nqi, nws yog qhov khoom ntawm kev kho dua reverse osmosis dej ua haujlwm. Txais tos rau ib qho kev nug.
