Reverse Osmosis membrane (RO) filter element
Ka tlhaho, tsela eo metsi a phallang ka eona e tloha sebakeng se tlaase sa mahloriso ho ea sebakeng se phahameng sa mahloriso, 'me lesela le ka morao la osmosis le fana ka khatello e lekaneng lehlakoreng le phahameng la mahloriso ho etsa hore metsi a khutlele ka lehlakoreng le leng la lera.Lera le ka morao la osmosis le ka boloka lintho tse kholo ho feta 0.0001μm (ke hore 0.1nm) (ho kenyeletsoa libaktheria le livaerase le lintho tse phelang tse nang le boima ba molek'hule bo fetang 100) 'me hajoale ke sehlahisoa sa karohano ea lera e hloekisitsoeng ka ho fetesisa' marakeng.Ha ho bapisoa le lintho tse ling tsa filthara, metsi a phallang ka mokokotlong oa osmosis a hloekile haholoanyane.Ho feta moo, li-membrane tsa reverse osmosis li boetse li hlahisa metsi a litšila.Lera le sa hlahiseng metsi a litšila ha ea lokela ho ba lera la reverse osmosis.
Nanofiltration membrane (NF) filter element
Li-membrane tsa nanofiltration hangata li na le li-membrane tse qosoang, tse nang le litefello tse mpe ka holim'a metsi, tse ka thibelang li-cations tse nang le li-valence tse fetang tse peli metsing le ho boloka li-ion tse mononovalent (joalo ka li-ion tsa sodium le li-ion tsa potassium).Ka hona, li-membrane tsa nanofiltration li boloka liminerale tse ling ka metsing.Ntho ea bohlokoa.
Har'a tse tloaelehileng tse silafatsang heavy metal, arsenic haholo-holo e teng ka metsing e le trivalent arsenic ion le pentavalent arsenic ion;chromium e fumaneha haholo ka sebopeho sa li-ion tse trivalent le tse hexavalent ka tlhaho.Kahoo lera la nanofiltration le lona le ka sefa boholo ba litšepe tse boima.E ka boela ea tlosa karolo ea calcium le magnesium, kahoo e na le phello e itseng ho nolofatsa metsi a thata.
Ka nako e ts'oanang, li-membrane tsa nanofiltration li ka fokotsa lintho tse phelang metsing le li-carcinogens tse kang trihalomethanes tse hlahisoang nakong ea chlorination le disinfection ea metsi a nooang.
Kokoana e nyenyane ka ho fetisisa e tsejoang e na le bophara ba 18nm-22nm (data e tsoang Wikipedia).Ha ho bapisoa le boholo ba pore ea li-membrane tsa nanofiltration tsa 1-2nm, libaktheria le likokoana-hloko li batla li le khōlō, kahoo li-membrane tsa nanofiltration li ka atleha Ho tlosoa ha libaktheria le likokoana-hloko ha ho bonahale ho le thata ho nahana.
Molao-motheo o sebetsang oa lera la nanofiltration o batla o tšoana le oa lera la reverse osmosis.Khatello eo e nang le eona e tlase ho feta ea lera la reverse osmosis, kahoo e hlahisa metsi a litšila a fokolang ho feta lera la reverse osmosis.
Sesefa sa lera la Ultrafiltration (UF).
Boholo ba pore ea lera la ultrafiltration ke 0.01μm (10nm).Lihloekisi tse ngata tsa metsi li tla hatisa hore lihloekisi tsa metsi tse sebelisang li-membrane tsa ultrafiltration li boloka liminerale ka metsing 'me ha li hlahise metsi a litšila.Be, ho lokile.Empa li-membrane tsa ultrafiltration ha li khone ho sefa litšepe tse boima.E ka sefa libaktheria ka katleho (libaktheria tse nyenyane ka ho fetisisa tse tsejoang li bolelele ba 0.2μm (200nm)) le likokoana-hloko tse ling tse kholoanyane.
Libakeng tse ling, metsi ke metsi a thata, ke hore, metsi a nang le calcium e ngata le magnesium.Metsi a mofuta ona a latsoeha hampe.Haeba u batla ho e fetola metsi a bonolo, se hloekisang metsi se sebelisang lera lena feela se ke ke sa finyella tlhokahalo.
Sefahla sa ceramic
Sefahla sa ceramic se ka sefa litšila, maloanlahla le libaktheria ka boholo bo bonyenyane ba pore ea thepa ea ceramic.Ke mofuta oa microfiltration membrane (MF).Li-ion tsa silevera tse khomaretsoeng ka ceramic li na le phello ea sterilizing.Mabapi le ho nepahala ha filthara ea "ceramic filter element", "dual-control membrane ceramic" element e nang le ts'ebetso e nepahetseng ka ho fetesisa lefatšeng ka bophara e na le pore ea boholo ba 0.1μm.Ho ea ka tekanyetso ena, leha sefahla sa ceramic se ka sefa baktheria efe kapa efe, ha se khone ho sefa livaerase tse ngata.
Ceramic ka boeona ha e khone ho tlosa litšila tse silafatsang tsa lik'hemik'hale, empa ntho ea ceramic filter e kopantsoeng le carbon activated e sebetsang hantle haholo e ka fokotsa litšila tsa tlhaho le litšila tsa tšepe, 'me e na le mosebetsi oa ho tlosa chlorine e setseng le ho tlosa mebala.Leha ho le joalo, mofuta ona oa motsoako o entsoeng ka ceramic filter o tlameha ho nkeloa sebaka khafetsa, hobane le hoja bokaholimo ba ceramic bo le bonolo ho bo hloekisa, k'habone e kentsoeng ka har'a ceramic e tla koaloa kamora nako ea ts'ebeliso.Haeba u nahana ka eona, u tla tseba hore phello ea adsorption e nyane kapa ha e na Holimo.
Sefahla sa resin
Li-filter tsa resin filter li sebelisoa hangata ho nolofatsa metsi a thata.Ha e khone ho sefa lirafshoa tse boima.
