Maitiro ekuchengeta reverse osmosis membrane zvinhu

1. New membrane elements

• Iyo membrane elements yakaedzwa kuti isvike mvura isati yabuda mufekitari, uye inochengetwa ne1% sodium sulfite solution, uyezve vacuum-yakazara nemabhegi ekuzviparadzanisa nevamwe;
• Iyo membrane element inofanirwa kuchengetwa yakanyorova nguva dzese. Kunyange kana zvakakosha kuivhura kwekanguva kuitira kusimbisa huwandu hwepakiti imwechete, inofanira kuitwa mune imwe nyika isingakuvadzi bhegi repurasitiki, uye iyi nyika inofanira kuchengetwa kusvikira nguva yekushandiswa;
• Iyo membrane element inonyanya kuchengetwa pakudzika kwakadzika kwe5 ~ 10 ° Paunenge uchichengeta munzvimbo ine tembiricha inopfuura 10 ° C, sarudza nzvimbo inofefetera zvakanaka, uye udzivise zuva rakananga, uye tembiricha yekuchengetedza haifanire kudarika 35 ° C;
• Kana iyo membrane element ikatonhora, ichakuvadzwa mumuviri, saka tora matanho ekudzivirira uye usaite chando;
• Paunenge uchirongedza zvinhu zve membrane, usarongedze anopfuura mashanu akaturikidzana emabhokisi, uye ita shuwa kuti katoni inochengetwa yakaoma.

2. Yakashandiswa membrane elements

• Iyo membrane element inofanira kuchengetwa munzvimbo ine rima nguva dzose, tembiricha yekuchengetedza haifanirwe kudarika 35 ° C, uye inofanira kudziviswa kubva kune zuva rakananga;
• Pane ngozi yechando kana tembiricha iri pasi pe0 ° C, saka matanho ekudzivirira kutonhora anofanira kutorwa;
• Kuti udzivise kukura kwema microorganisms panguva yenguva pfupi yekuchengetedza, yekufambisa uye system standby, zvinodikanwa kugadzirira sodium sulfite (yekudya giredhi) inodzivirira mhinduro ine 500 ~ 1,000ppm uye pH3 ~ 6 kunyudza chinhu nemvura yakachena kana reverse osmosis inogadzirwa mvura. Kazhinji, Na2S2O5 inoshandiswa, iyo inopindirana nemvura kuita bisulfite: Na2S2O5 + H2O—
• Mushure mekunyudza iyo membrane element mune inochengetedza mhinduro kweinenge awa 1, bvisa iyo membrane element kubva mumhinduro uye uiise mubhegi reokisijeni yekuzviparadzanisa nevamwe, simbisa bhegi uye rinyore nezuva rekurongedza.
• Mushure mekunge iyo membrane element ichachengetwa yakarongedzerwa, mamiriro ekuchengetedza akafanana neaya echinhu chitsva che membrane.
• Iko kusungirirwa uye pH yegadziriro yekuchengetedza inofanira kuchengetwa mumutsara wepamusoro, uye inofanira kuongororwa nguva dzose, uye kana inogona kutsauka kubva pane iri pamusoro apa, sarudzo yekuchengetedza inofanira kugadzirirwa zvakare;
• Pasinei nemamiriro ezvinhu apo membrane inochengetwa, membrane haifaniri kusara yakaoma.
• Mukuwedzera, iyo yekuisa (mass percentage concentration) ye0.2 ~ 0.3% formaldehyde solution inogonawo kushandiswa semhinduro yekuchengetedza. Formaldehyde inouraya utachiona hwakasimba kupfuura sodium bisulfite uye haina oxygen.
