Ulwelwesi lwe-Nanofiltration luvame ulwelwesi olushajwayo, olunamashaji angemahle ngaphezulu, olunganqamula ama-cations anama-valence angaphezu kwamabili emanzini futhi lugcine ama-ion amonovalent (njengama-ion e-sodium nama-ion potassium).Ngakho-ke, ulwelwesi lwe-nanofiltration lugcina amanye amaminerali emanzini.Isici esibalulekile.
Phakathi kwezinto ezingcolisa insimbi ezisindayo ezivamile, i-arsenic itholakala ikakhulukazi emanzini njengama-ion a-arsenic angama-trivalent nama-pentavalent arsenic ion;I-chromium itholakala ikakhulukazi ngesimo sama-ion angama-trivalent nama-hexavalent emvelweni.Ngakho ulwelwesi lwe-nanofiltration lungaphinda luhlunge izinsimbi eziningi ezisindayo.Ingaphinde isuse ingxenye ye-calcium ne-magnesium, ngakho-ke inomphumela othile ekuthambisa amanzi aqinile.
Ngesikhathi esifanayo, ulwelwesi lwe-nanofiltration lunganciphisa izinto eziphilayo emanzini kanye nama-carcinogens afana ne-trihalomethanes akhiqizwa ngesikhathi se-chlorination kanye nokubulala amagciwane emanzini okuphuza.
Igciwane elincane elaziwayo linobubanzi obungu-18nm-22nm (idatha evela ku-Wikipedia).Uma kuqhathaniswa nosayizi we-pore we-nanofiltration membranes ye-1-2nm, amabhaktheriya namagciwane akhulu kakhulu, ngakho ulwelwesi lwe-nanofiltration lungasebenza Ukususwa kwamagciwane namagciwane akubonakali kunzima ukukucabanga.
Isimiso sokusebenza solwelwesi lwe-nanofiltration lucishe lufane nalolo lwe- reverse osmosis membrane.Ingcindezi enayo iphansi kunaleyo yolwelwesi lwe-osmosis ehlehlayo, ngakho ikhiqiza amanzi angcolile amancane kunolwelwesi lwe-osmosis oluhlehlayo.
Ukuba ngomunye wabakhiqizi bokuqala be-membrane ye-RO e-China, HIDTMiklelisa amabhrendi amahle kakhulu phakathi kwemboni ye-membrane yaseShayina ye-RO.I-Nanofiltration membranes ingakwazi ukuhlunga i-ion yensimbi ngaphezu kwama-valence amabili emanzini (ngokuvamile, okuqukethwe kwe-ion monovalent emanzini kuncane kakhulu, futhi wonke angamaminerali anenzuzo emzimbeni womuntu), kuyilapho ukucindezela kokusebenza kwe-nanofiltration membranes kuphansi kakhulu i-osmosis ehlehlisa ulwelwesi, kanye nokuphuma kwamanzi Iphakeme kakhulu kune-osmosis ehlehlayo futhi ingasusa ngokuphelele ama-ion e-calcium ne-magnesium okulula ukuwakala emanzini.Ukusetshenziswa kwe-nanofiltration membranes kwanele ukuhlangabezana nezidingo zamanzi okuphuza.
- Kungumkhiqizo okhetheka kakhulu we-nanofiltration membrane owenzelwe ngokukhethekile ukukhishwa kwe-zero kanye nokusetshenziswa kwezinsiza.
- Izinga lokulahlwa kwe-ion ye-multivalent liphezulu, izinga lokwenqatshwa kwama-ion e-monovalent liphansi, futhi ukusika kwesisindo se-molecular kunembile.
- Ibuye ilungele izidakamizwa ezincane zokuhlaziya Isolation and Purification.
- Idizayini yegridi ekhethekile iyamukelwa kumzila wokugeleza we-inlet ukuze umkhiqizo ube nezinzuzo ezibaluleke kakhulu ekumelaneni nokungcola nokuhlanza kalula.
Qaphela:
1. Amapharamitha wokusebenza akalwa ngemuva kokuthi isistimu isebenze ngokuzinzile imizuzu engama-30.2. Uhla lokuchezuka kokukhiqizwa kwamanzi ±15%.
2.1.5 Ulwazi olubalulekile
Ukuqala okulungile kubalulekile ekusebenzeni okuzinzile kwesistimu ye-nanofiltration.Ngaphambi kokuthi uhlelo lwe-nanofiltration lususwe iphutha noma luqalwe kabusha ngaphansi kwe-
isimo sokuvala isikhathi, amathuluzi ahlukahlukene, amamitha, kanye nekhwalithi yamanzi kufanele kuhlolwe futhi kulungiswe ukuze kuqinisekiswe ukuthi zonke izimo ziyahlangabezana nezilungiselelo noma ukusetha amanani.
ngemva kokuthunyelwa.Sicela ubheke imanuwali yomkhiqizo ngezinyathelo ezithile zokusebenza nezinyathelo zokuphepha.
Ukuze uvimbele ulwelwesi ukuthi lungaklwejwa yizinhlayiya eziqinile, isihlungi esithembekile sokuphepha esingu-5μm ngaphandle kokuwashwa ngemuva kufanele sisetshenziswe emanzini.
indawo yokungena.Uma ukugxiliswa kwe-silicon kuphezulu kakhulu, isihlungi sokuvikela esingu-1μm singasetshenziswa.Ukucindezela ohlangothini lokukhiqiza amanzi lwemodyuli ye-membrane kumele
ingabi ngaphezu kokucindezela ohlangothini lwamanzi okuphakelayo nganoma yisiphi isikhathi, futhi ingcindezi engemuva emile kufanele ibe ngaphansi kuka-5 psi.
Ifemu yethu igcizelela ngaso sonke isikhathi inqubomgomo yekhwalithi “yekhwalithi ephezulu yomkhiqizo iyisisekelo sokusinda kwenhlangano;ukugcwaliseka komthengi kungaba isiqalo nesiphetho senkampani;ukuthuthukiswa okuqhubekayo ukuphishekela abasebenzi kwaphakade” kanye nenjongo engaguquki “yesithunzi sokuqala, umthengi kuqala” we-Nanofiltration Membrane, ulwelwesi lwe-NF, Umgomo Webhizinisi: Ukwaneliseka kwamakhasimende kuwumgomo wethu, futhi sithemba ngobuqotho ukusungula ubudlelwano obuzinzile bokusebenzisana besikhathi eside. namakhasimende ukuthuthukisa ngokuhlanganyela imakethe.Ukwakha okuhle kusasa ndawonye!Inkampani yethu ibheka “izintengo ezifanele, isikhathi sokukhiqiza esisebenza kahle kanye nenkonzo enhle yangemva kokuthengisa” njengemfundiso yethu.Sithemba ukubambisana namakhasimende amaningi ukuze sithuthukiselane futhi sizuze.Samukela abathengi abangahle baxhumane nathi.E-mail: info@ro-hid.com
I-HID™ NF Membranes isetshenziswa kabanzi ku:
1. Imithi elwa namagciwane igxiliswa emazingeni okushisa aphansi ukususa umlotha.
2. Ukukhipha usawoti emanzini, ukugxilisa ingqondo, ukubuyisela usawoti ngaphandle, imvula ye-asidi.
3. Ukugxila koketshezi olushukela omncane, ukuhlanzwa kwama-oligosaccharides.
4. Ukukhishwa kanye nokugxila kwezithako ezisebenzayo eziphilayo.
5. Ukuhlanza nokugaywa kabusha kwamanzi.
6. Ukugxila nokuhlanzwa kwamaprotheni ahlukahlukene, ama-amino acid, amavithamini, ubisi, utshwala, isoso soy, ama-condiments, njll.
