Sei iyo itsva RO Membrane Isiri Kushanda?Ngatitaure nezve zvikonzero uye mhinduro pazasi:
1. Tembiricha yemvura inopinza yakadzikira:
Iyo yakajairwa tembiricha yekushanda yereverse osmosis membrane ndeye 25 ℃, uye kugadzirwa kwemvura kunodzikira ne3% pese painodonha tembiricha nedhigirii rimwe.Kana tembiricha yakadzikira kupfuura 0°C, mvura yakasvibira inogwamba uye haigoni kuburitsa mvura sezvaingoitawo.
2. Mvura inopinza yakaderera zvikuru:
Nheyo yekushanda ye reverse osmosis membrane ndeye kusefa nekumanikidza.Kana iyo booster pombi ikashandiswa kwenguva yakareba, iyo inlet pressure inodonha, uye mvura yakasvibira haigone kuzadzisa zvinodiwa, zvichiita kuti pasave nemvura inobuda mureverse osmosis system.Kazhinji, kumanikidza kwekushanda kweiyo reverse osmosis membrane inoda kusvika 4.14MPA.
3. Kufurira pH
Yakasiyana RO membrane modules ine inotenderwa pH renji, uye iyo pH yemvura ine simba inenge isina mhedzisiro pakugadzirwa kwetater.Asi kunyange mukati memuganhu unobvumirwa, ine simba guru pakuramba munyu.Kune rimwe divi, iyo pH kukosha zvakare ine imwe mhedzisiro pane conductivity yemvura yechigadzirwa.Izvi zvinodaro nekuti reverse osmosis membrane pachayo kazhinji ine mamwe mapoka anoshanda, uye iyo pH kukosha inogona kukanganisa membrane.Munda wemagetsi pamusoro pepamusoro unokanganisa kutama kweion.Iyo pH kukosha ine yakananga mhedzisiro pachimiro chetsvina mune inofurira.Semuenzaniso, kune dissociable organics, chiyero chekuramba chinodzikira nekudzikira kwepH.Kune rimwe divi, nekuti iyo yakanyungudika CO2 mumvura inobatwa zvakanyanya neiyo pH kukosha, kana iyo pH kukosha yakaderera, iripo muchimiro chegasi CO2 uye inopinda nyore nyore reverse osmosis membrane.Naizvozvo, mwero wekuramba munyu wakaderera kana pH kukosha yakaderera.Sezvo pH inowedzera, gaseous CO2 inoshandurwa Kune HCO-3 uye CO2-3 ions, munyu wekuramba munyu unowedzera zvishoma nezvishoma, uye munyu wekuramba munyu unosvika pakakwirira pakati pe pH 7.5 uye 8.5.
4. Kupesvedzera munyu
Osmotic pressure ibasa rekusangana kwemunyu kana organic matter mumvura.Iyo yakakwirira yemunyu, iyo osmotic pressure inowedzera.Kana iyo inlet pressure ikaramba yakafanana, iyo net pressure inodzikira uye kugadzirwa kwemvura kunoderera.Kupinda munyu kunoenzanirana nemusiyano wemunyu uripakati pemberi nekuseri kwe membrane.Iyo yakakwira munyu weiyo inofurira, iyo yakakura mutsauko wekuisa, uye kuwedzera kwemunyu kunowedzera, izvo zvinotungamira kuderera kwehuwandu hwekuramba munyu.Kune imwecheteyo sisitimu, iyo yekudyisa mvura yemunyu yemukati yakasiyana, iyo yekushanda kumanikidza uye chigadzirwa chemvura conductivity zvakare zvakasiyana.Pakuwedzera kwega kwega kwemvura yekudyisa munyu wemukati ne100 ppm, iyo inopinza mvura yekumanikidza inoda kuwedzera neinosvika 0.007 MPa.Panguva imwecheteyo, nekuda kwekuwedzera kwekugadzirisa, chigadzirwa chemvura conductivity Uyezve yakawedzera maererano.
5. Pretreatment blockage:
Reverse osmosis membranes ine zvakati wandei zvinodikanwa pakudya kwemvura, uye akakodzera pretreatment zvishandiso, senge quartz jecha mafirita, mafirita ekuchengetedza, nezvimwewo, anowanzowedzerwa pamberi pemembrane element.Kana ikashandiswa kwenguva yakareba, iyo pretreatment mudziyo inogona kuvharika nekuda kwekunyanya kusvibiswa.Mushure mekuvhara, pachava nekumwe kudonha kwekugadzirwa kwemvura.Kana iyo pretreatment tsvina yakavharwa zvachose, iyo mbishi mvura haigone kupinda reverse osmosis membrane kuburikidza ne pretreatment, ipapo reverse osmosis Iyo membrane ichaonekwa inodaidzwa kuti hapana mvura.
6. Cheki vharuvhu yakavharwa:
Panguva yekushandiswa, cheki valve inogonawo kuvharwa nekusachena.Iwe unogona kutora cheki valve kunze kuti uone kana kugadzirwa kwemvura kwehurongwa kwakawedzera zvakanyanya.Kazhinji, mukana wekutarisa kuvhara kwevhavha ishoma.
7. Reverse osmosis membrane yakavharwa netsvina:
Mukuwedzera kune pretreatment inogona kuvharwa, reverse osmosis membranes inogonawo kuvharwa.Mvura yakasvibira ine tsvina yakawanda.Kazhinji mudziyo wepretreatment unogona kusefa yakawanda yetsvina kuita kuti mvura ine simba isangane nezvinodiwa zvereverse osmosis.Zvakadaro, mamwe masisitimu ekurapa akagadzirwa zvisina musoro, zvichikonzera kusvibiswa senge organic matter, yemahara chlorine, uye yakaturikwa yakaoma.Mukati memembrane element, zvichikonzera kuvharika kwe membrane element.Kana tsvina ichivharira zvachose membrane pore size, hapazove nekugadzirwa kwemvura.
8. Iyo post-sefa system yakavharwa:
Mukushandiswa kwekushandiswa, matanho ekudzivirira akakodzera anowanzowedzerwa kuseri kwereverse osmosis membrane kudzivirira mvura yechigadzirwa kubva pakukanganiswa nezvimwe zvinhu, senge activated carbon filtration, precision filtration, etc. Zvishandiso izvi zvinogona kuvharwa nesefa zvinhu uye inokanganisa zvakare reverse osmosis yekugadzirwa kwemvura kweiyo system.
Solution:
1. Chigadziro chekugadzirira chine nhamba yakawanda yezvigadzirwa zvemasefa, zvinoda kuchinjwa uye kucheneswa nguva dzose, izvo zvinogona kunyatsodzivirira chigadziro chekugadzirira kubva pakuvharwa.
2. Mushure mokunge reverse osmosis membrane yakavharwa, inowanzokurudzirwa kushandisa kemikari yekuchenesa kubvisa tsvina mukati me membrane element, iyo inogona kunyatso kudzorera filtration performance ye membrane element.Uye optimize pretreatment system.
3. Kuderera kwakadzika kwemvura yakasvibirira kunowanzokonzerwa nekukwegura kwepombi yebooster, ingotsiva pombi inosimudzira.
4. Mushure mokunge cheki chekivha yakavharwa, inoda kucheneswa nemvura yakachena uye kucheneswa isati yashandiswa.Kana isingakwanisi kucheneswa, cheki valve inoda kuchinjwa.
5. Matanho akakodzera ekudzivirira anofanira kutorwa paunenge uchishandisa reverse osmosis membranes munguva yechando.
6. Kana iyo post-filter system yakaiswa mukati mesefa zvinhu, imwe nzvimbo inofanira kuchengetwa kudzivirira yakawandisa sefa zvinhu kubva pakuvhara system.
