Maitiro ekushandisa iyo itsva RO reverse osmosis membrane nenzira kwayo?

• Mapoinzi ehunyanzvi ekushandisa iyo itsva RO reverse osmosis membrane:
  Chekutanga, sukurudza jecha requartz uye coconut shell activated carbon, uye sukurudza ichangobva kuiswa quartz jecha nekokonati shell yakagadziriswa kabhoni kwenguva yakareba.
  2. Tarisa uone kana paine chlorine yasara, kana paine chlorine yasara inodarika mwero, gadzirisa dambudziko reklorini rasara uye woenderera mberi kudanho rinotevera reRO reverse osmosis membrane.
  3. Mushure mokunge firimu itsva yaiswa, idiridza uye inyura firimu kwemaawa 1 ~ 2, nokuti iyo firimu yakaoma, iyo yakanyoroveswa firimu inenge yakanyorova kuitira kuti firimu isakuvadzwe nekudzvinyirira kwakanyanya.
  4. Zvadaro tanga pombi yepamusoro-soro, kudzvinyirira kunofanira kuwedzera zvishoma nezvishoma, kubva pa 2 kg kusvika ku8 ~ 10 kg, desalination rate ye membrane itsva iri nani.
  5. Iyo yakasara chlorine inodzorwa pasi pe0.003.
  6. Vhura vheji yemvura yakanyanyisa usati watanga pombi yepamusoro-soro, uye zvishoma nezvishoma gadzirisa vheji yemvura yakanyanyisa mushure mokunge pombi yepamusoro yakazarurwa kuti idzore chiyero chekudzorera che membrane imwe chete inenge 15%.
  7. Mvura inogadzirwa muhafu yekutanga yeawa inofanira kuderedzwa, nokuti pane mvura inodzivirira mu membrane kuti irege kukanganisa kuravira kwemvura.
  8. Tsvaga kukosha kwePH yemvura ine simba, pamusoro pe6.5.

• Nzira yekutonga sei kuti reverse osmosis membrane inoda kucheneswa?

Reverse osmosis membrane zvinhu zvinogona kushandiswa kwenguva ingangoita 2 ~ 3 makore. Kana iwe uchida kuwedzera hupenyu hwesevhisi, iwe unogona kuchenesa reverse osmosis membrane zvinhu, izvo zvinowanzo kupatsanurwa kuita nzira mbiri: kuputika kwemuviri uye kuputika kwemakemikari.

Kuchenesa kwe reverse osmosis membranes

Sekutonga kwechigunwe, kana reverse osmosis unit yakacheneswa mwedzi mitatu kana kupfuura. Kana yakacheneswa kamwe chete pamwedzi 1-3, zvakakosha kuvandudza mamiriro ekushanda uye kuvandudza maitiro ekugadzirisa.

Tongai mamiriro ekuchenesa:

(1) Kugadzirwa kwemvura yakachena kwakamisikidzwa kwakadzikira neinopfuura 10%.

(2) Iyo yakajairwa munyu permeability mwero wakawedzera neinopfuura 10%.

(3) Kuti uchengetedze mwero wakajairika wekuyerera kwemvura yakachena, mutsauko wekumanikidza pakati pemvura yekudyisa nemvura yakadzika inowedzerwa neinopfuura 10% mushure mekugadzirisa tembiricha.

(4) Chishandiso chemukati chine zvakakomba zvinosvibisa uye chiyero.

(5) Pamberi peRO mudziyo wakadzimwa kwenguva yakareba.

(6) Kugadziriswa kwemaitiro eRO midziyo.

Contaminant

Izvo zvakajairika zvinosvibisa mune reverse osmosis membrane zvinhu zvakanyanya CaCO3, CaSO4, BaSO4, SrSO4, simbi oxides, silicon deposits, organic zvinhu uye biological slime. Kana iyo scale inhibitor dosing system kana asidi yekuwedzera system ikatadza, CaCO3 inogona kuiswa mu membrane zvinhu, uye kuchenesa kemikari kunofanirwa kushandiswa kuchenesa cyclic kana kunyura kwehusiku.

Kugadzira

Zvakasiyana zvinosvibisa zvinokonzeresa madhigirii akasiyana ekukuvadza kune membrane, uye zvinosvibisa zvakasiyana zvinoshandisa nzira dzakasiyana dzekuchenesa.

Kuchenesa michina

Inowanzo kuumbwa pombi yekuchenesa, bhokisi rekugadzirira makemikari, 5-20um chengetedzo sefa, hita, ine hukama mavharuvhu epombi uye zviridzwa zvekudzora.

Nzira dzekuchenesa dzinosanganisira static soaking uye cyclic kuchenesa. Static soaking yakanyudzwa mumvura yekuchenesa, uye nguva yacho ingangoita 1-15h zvichienderana nehuwandu hwekusvibiswa. Matanho akajairwa ekuchenesa cyclic ndeaya:

1. Pomba mvura yakachena kubva mubhokisi rekugadzirira mumudziyo wekumanikidza uye uibudise kwemaminitsi mashomanana.

2. Gadzirira mhinduro yekuchenesa nemvura yakachena mubhokisi rekugadzirira.

3. Kutenderera ngarava yekumanikidza nemvura yekuchenesa kweawa imwe kana kusvika panguva yakatarwa. Kuyerera kwekuchenesa kuyerera kunogona kutsanangurwa maererano netafura iri pasi apa, uye kana kusvibiswa kwakanyanya, kuyerera kwekuchenesa kunogona kuwedzerwa kusvika ku150% ye resin iri patafura. Panguva ino, kudonhedza kwekuchenesa kudonha kwakakura, uye kutonga kwese hakuna kupfuura (0.10-0.14MPa)/root film element kana 0.4MPa/root film assembly. Pakutanga kwekucheneswa kwemushonga, 50% yehuwandu hwekuyerera mumamita inogona kushandiswa kudira iyo inopisa yekuchenesa mhinduro mumudziyo wekumanikidza kudzora kudzvanywa, kuitira kuti ikunde kudonha kwekumanikidza pakati peinopinza uye yekubuda mvura pasina mvura yakachena inoyerera kunze. Kuti udzivise kuderedzwa kwemhinduro yekuchenesa, iyo yakadzika vheji yekuburitsa mvura inogona kuvhurwa kuti ibvise mvura yakaunganidzwa kubva muhurongwa isati yacheneswa. Iyo reverse osmosis system inogona kucheneswa muzvikamu. Iyo nzira yekuchenesa yakafanana neyekumhanya kutungamira, uye reverse kucheneswa hakubvumidzwe, zvikasadaro zvinogona kuita kuti iyo firimu roll iwedzere uye kukuvadza zvinhu zvemufirimu.

4. Mushure mekuchenesa kutenderera kwapera, geza bhokisi rekugadzirira nemvura yakachena.

5. Rinisa mudziyo wekumanikidza nemvura yakachena.

6. Mushure mekutsvaira, mhanyisa reverse osmosis system nevhavha yekuburitsa mvura yakachena yakavhurika kusvika mvura yakachena yachena, isina furo, kana isina mvura yekuchenesa, iyo inowanzotora maminitsi gumi nemashanu-30.

Reverse osmosis membrane kutsiva

Mushure mekushanda kwakajairwa kweiyo reverse osmosis midziyo kwenguva yakati rebei, reverse osmosis membrane zvinhu zvichasvibiswa neyakamiswa solids kana insoluble munyu inogona kunge iripo mumvura yekudyisa, uye zvinotevera zviratidzo zvichaonekwa:

1. Huremu hwe membrane zvinhu zve reverse osmosis midziyo yakawedzera;
2. Iyo RO membrane yekubvisa mwero yakawedzera kana kuderera zvakanyanya;
3. Pasi pekumanikidzwa kwakajairwa, goho remvura reverse osmosis midziyo yakadzikira zvakanyanya.
4. Kuti uwane chiyero chemvura yegoho, kushandiswa kwekushanda kunoda kuvandudzwa;
5. Kudonha kwekumanikidza pakati pemvura ine simba uye yakadzika mvura ye reverse osmosis midziyo inowedzera;
6. Bvisa membrane element kubva mumudziyo wekumanikidza, dururira mvura kudivi rekupinza reiyo yakatwasuka membrane element, kana mvura isingagoni kuyerera nepakati membrane element, inongofashukira kubva kumagumo kumeso, zvichiratidza kuti iyo inlet inoyerera chiteshi yakavharwa.
