Reverse osmosis inwebu (RO) filter element
Ngokwemvelo, isikhokelo sokuhamba kwamanzi sisuka kwicala eliphantsi lokugxininiswa ukuya kwicala eliphezulu lokugxininiswa, kwaye i-osmosis ye-reverse membrane yenza uxinzelelo olwaneleyo kwicala loxinzelelo oluphezulu ukwenza amanzi abuyele kwelinye icala le-membrane. I-reverse osmosis inwebu inokugcina izinto ezinkulu kune-0.0001μm (okt 0.1nm) (kubandakanywa iibhaktheriya kunye neentsholongwane kunye nezinto eziphilayo ezinobunzima be-molecular ngaphezu kwe-100) kwaye ngoku yeyona mveliso yokwahlula inwebu esulungekisiweyo kwimarike. Xa kuthelekiswa nezinye izinto zokucoca, amanzi aqukuqela kwi-reverse osmosis membrane asulungekile. Ukongeza, iimbrane ze-osmosis ezibuyela umva zivelisa amanzi amdaka. Inwebu engavelisi amanzi amdaka kufuneka ingabi yi- reverse osmosis inwebu.
Nanofiltration inwebu (NF) isihluzi element
I-Nanofiltration membranes idla ngokuhlawuliswa ii-membrane, ezinemirhumo engalunganga kumphezulu, enokuthi ithintele i-cations ngee-valences ezingaphezu kwesibini emanzini kwaye igcine i-ion ze-monovalent (ezifana ne-sodium ion kunye ne-potassium ion). Ngoko ke, i-nanofiltration membranes igcina ezinye iiminerali emanzini. Izinto eziphathekayo.
Phakathi kwezinto ezingcolisa isinyithi esinzima eziqhelekileyo, i-arsenic ifumaneka ikakhulu emanzini njenge-trivalent ion arsenic kunye ne-pentavalent arsenic ion; Ichromium ikhona ikakhulu ngohlobo lweeyoni ezithathu kunye nehexavalent kwindalo. Ke i-nanofiltration membrane inokucoca ngaphandle uninzi lwesinyithi esinzima. Iyakwazi ukususa inxalenye ye-calcium kunye ne-magnesium, ngoko inefuthe elithile ekuthobeni kwamanzi anzima.
Ngelo xesha, i-nanofiltration membranes inokunciphisa into ephilayo emanzini kunye ne-carcinogens efana ne-trihalomethanes eveliswa ngexesha le-chlorination kunye ne-disinfection yamanzi okusela.
Intsholongwane encinci eyaziwayo inobubanzi be-18nm-22nm (idatha esuka kwi-Wikipedia). Xa kuthelekiswa nobukhulu bepore ye-nanofiltration membranes ye-1-2nm, iibhaktheriya kunye neentsholongwane zinkulu kakhulu, ngoko i-nanofiltration membranes inokusebenza Ukususwa kweebhaktheriya kunye neentsholongwane akubonakali kunzima ukucinga.
Umgaqo wokusebenza we-nanofiltration inwebu ngokuyinxenye uyafana naleyo ye-reverse osmosis membrane. Uxinzelelo oluthweleyo lungaphantsi kunolo lwe- reverse osmosis inwebu, ngoko ke luvelisa amanzi amdaka amancinci kune- reverse osmosis inwebu.
Ultrafiltration inwebu (UF) isihluzi element
Ubungakanani bepore ye-ultrafiltration membrane yi-0.01μm (10nm). Abaninzi abacoci bamanzi baya kugxininisa ukuba abacoci bamanzi abasebenzisa kuphela i-membrane ye-ultrafiltration bagcina amaminerali emanzini kwaye abavelisi amanzi amdaka. Ewe, kunjalo. Kodwa ii-membrane ze-ultrafiltration azikwazi ukuhluza iintsimbi ezinzima. Iyakwazi ukuhluza iibhaktheriya ngokufanelekileyo (ibhaktheriya encinci eyaziwayo yi-0.2μm (200nm) ubude) kunye nezinye iintsholongwane ezinkulu.
Kwezinye iindawo, amanzi angamanzi anzima, oko kukuthi, amanzi ane-calcium eninzi kunye ne-magnesium. Olu hlobo lwamanzi lunencasa embi. Ukuba ufuna ukuyiguqula ibe ngamanzi athambileyo, isicoci samanzi esebenzisa le membrane kuphela asikwazi ukuhlangabezana nemfuno.
Isihluzo seCeramic
Isihluzo se-ceramic sinokuhluza intlenga, inkunkuma, kunye neebhaktheriya ngobungakanani bepore encinci yemathiriyeli yeceramic. Luhlobo lwe-microfiltration membrane (MF). Iiyoni zesilivere ezifakwe kwi-ceramic zinefuthe le-sterilizing. Ngokumalunga nokuchaneka kohluzo lwe-ceramic filter element, i-double-control inwebu yesihluzo se-ceramic element enelona cwecwe liphezulu lokuchaneka kwihlabathi linobungakanani bepore obuyi-0.1μm. Ngokwalo mgangatho, nangona i-ceramic filter element inokucoca nayiphi na ibhaktheriya, ayinakuhluza iintsholongwane ezininzi.
I-Ceramic ngokwayo ayikwazi ukususa ungcoliseko lweekhemikhali, kodwa into yokucoca i-ceramic edityaniswe nekhabhoni esebenzayo ephezulu inokunciphisa ungcoliseko lwendalo kunye nongcoliseko lwesinyithi, kwaye inomsebenzi wokususa intsalela yeklorini kunye nokunciphisa umbala. Nangona kunjalo, olu hlobo lwezinto ezidibeneyo zokucoca i-ceramic kufuneka zitshintshwe rhoqo, kuba nangona i-ceramic surface kulula ukuyicoca, i-carbon esebenzayo ezaliswe kwi-ceramic iya kuvinjelwa emva kwexesha lokusetyenziswa. Ukuba ucinga ngayo, uya kwazi ukuba isiphumo se-adsorption sincinci okanye akukho Phezulu.
Isihluzo se-resin
Izinto zokucoca iresin zidla ngokusetyenziswa ukuthambisa amanzi aqinileyo. Ayikwazi ukuhluza iintsimbi ezinzima.
