Momwe mungasungire zinthu zam'mbuyo za osmosis

1. Zinthu zatsopano za membrane

• Zinthu za nembanemba zayesedwa kuti zidutse madzi asanachoke ku fakitale, ndipo zimasungidwa ndi 1% sodium sulfite solution, ndiyeno vacuum yodzaza ndi matumba odzipatula a oxygen;
• The membrane element iyenera kukhala yonyowa nthawi zonse. Ngakhale kuli kofunikira kuti mutsegule kwakanthawi kuti mutsimikizire kuchuluka kwa phukusi lomwelo, liyenera kuchitidwa m'boma lomwe silingawononge thumba la pulasitiki, ndipo dziko lino liyenera kusungidwa mpaka nthawi yogwiritsira ntchito;
• The nembanemba chinthu bwino kusungidwa pa kutentha otsika 5 ~ 10 ° Pamene kusunga mu chilengedwe ndi kutentha kuposa 10 °C, sankhani malo mpweya wabwino, ndi kupewa kuwala kwa dzuwa, ndi kusunga kutentha si upambana 35 °C;
• Ngati nembanemba imaundana, imawonongeka, choncho tsatirani njira zotchinjiriza ndipo musawumitse;
• Mukasanjikiza zinthu za nembanemba, musanyamule mabokosi opitilira 5, ndipo onetsetsani kuti makatoniwo akuwuma.

2. Ntchito za membrane

• Chinthu cha membrane chiyenera kusungidwa m'malo amdima nthawi zonse, kutentha kosungirako sikuyenera kupitirira 35 ° C, ndipo kuyenera kupewedwa ndi dzuwa;
• Pali chiopsezo cha kuzizira pamene kutentha kuli pansi pa 0 ° C, choncho njira zoletsa kuzizira ziyenera kuchitidwa;
• Pofuna kupewa kukula kwa tizilombo mu nthawi yochepa yosungirako, mayendedwe ndi dongosolo standby, m`pofunika kukonzekera sodium sulfite (chakudya kalasi) zoteteza njira ndi ndende ya 500 ~ 1,000ppm ndi pH3 ~ 6 zilowerere zinthu ndi madzi oyera kapena n'zosiyana osmosis opangidwa madzi. Nthawi zambiri, Na2S2O5 imagwiritsidwa ntchito, yomwe imachita ndi madzi kupanga bisulfite: Na2S2O5 + H2O—
• Mutatha kuviika nembanemba mu njira yosungiramo kwa ola limodzi, chotsani chinthu cha nembanemba mumtsuko ndikuchiyika mu thumba lodzipatula la okosijeni, sindikizani chikwamacho ndikulembapo tsiku loyikapo.
• Chigawo cha nembanemba chomwe chiyenera kusungidwa chikapakidwanso, zosungirako zimakhala zofanana ndi zomwe zili ndi nembanemba yatsopano.
• Kukhazikika ndi pH ya njira yosungiramo kuyenera kusungidwa pamwamba pazimenezi, ndipo ziyenera kufufuzidwa nthawi zonse, ndipo ngati zingapatuke pazigawo zomwe zili pamwambazi, njira yotetezera iyenera kukonzedwanso;
• Mosasamala kanthu za momwe membrane imasungidwira, nembanembayo siyenera kusiyidwa youma.
• Kuphatikiza apo, ndende (kuchuluka kwa kuchuluka) kwa 0.2 ~ 0.3% formaldehyde solution ingagwiritsidwenso ntchito ngati njira yosungira. Formaldehyde ndi wakupha tizilombo wamphamvu kwambiri kuposa sodium bisulfite ndipo ilibe mpweya.
