Ungawagcina kanjani ama-reverse osmosis membrane element

1. Izakhi zolwelwesi olusha

• Izakhi ze-membrane ziye zahlolelwa ukudlula kwamanzi ngaphambi kokuphuma embonini, futhi zigcinwa ngesisombululo se-sodium sulfite esingu-1%, bese kufakwe i-vacuum-packed nezikhwama zokuhlukanisa umoya-mpilo;
• Ingxenye ye-membrane kufanele igcinwe imanzi ngaso sonke isikhathi. Ngisho noma kudingekile ukuyivula okwesikhashana ukuze kuqinisekiswe ubuningi bephakheji elifanayo, kufanele lenziwe esimweni esingalimazi isikhwama sepulasitiki, futhi lesi simo kufanele sigcinwe kuze kufike isikhathi sokusetshenziswa;
• Isici se-membrane sigcinwa kangcono ekushiseni okuphansi kwe-5 ~ 10 ° Uma ugcina endaweni enezinga lokushisa elingaphezu kuka-10 °C, khetha indawo enomoya omuhle, futhi ugweme ilanga eliqondile, futhi izinga lokushisa lokugcina akufanele lidlule ku-35 °C;
• Uma i-membrane element iqhwa, izolimala ngokomzimba, ngakho-ke thatha izinyathelo zokuhlukanisa futhi ungayifaki iqhwa;
• Uma upakisha izakhi ze-membrane, ungapakishi izingqimba ezingaphezu kwezingu-5 zamabhokisi, futhi uqiniseke ukuthi ibhokisi ligcinwa lomile.

2. Izakhi ze-membrane ezisetshenzisiwe

• Isici se-membrane kufanele sigcinwe endaweni emnyama ngaso sonke isikhathi, izinga lokushisa lokugcina akufanele lidlule i-35 ° C, futhi kufanele ligwenywe elangeni eliqondile;
• Kunengozi yokubanda lapho izinga lokushisa lingaphansi kuka-0°C, ngakho-ke izinyathelo zokunqanda ukuqandisa kufanele zithathwe;
• Ukuze uvimbele ukukhula kwama-microorganisms ngesikhathi sokugcina isikhathi esifushane, ezokuthutha kanye nokulinda kwesistimu, kuyadingeka ukulungisa isisombululo sokuzivikela se-sodium sulfite (ibanga lokudla) nge-concentration ye-500 ~ 1,000ppm ne-pH3 ~ 6 ukucwilisa i-elementi ngamanzi ahlanzekile noma i-osmosis ehlehlisiwe ekhiqizwa amanzi. Ngokuvamile, i-Na2S2O5 isetshenziswa, ehlangana namanzi ukwenza i-bisulfite: Na2S2O5 + H2O—
• Ngemva kokucwilisa isici se-membrane esixazululweni sokulondoloza cishe ihora elingu-1, susa isici se-membrane esixazululweni bese usipakisha esikhwameni sokuhlukanisa umoya-mpilo, vala isikhwama bese usibhala ngedethi yokupakisha.
• Ngemva kokuba i-elementi ye-membrane ezogcinwa isipakishwe kabusha, izimo zokulondoloza ziyefana nalezo zesici esisha se-membrane.
• Ukugxila kanye ne-pH yesisombululo sokulondoloza kufanele kugcinwe ebangeni elingenhla, futhi kufanele ihlolwe njalo, futhi uma ingase iphambuke ohlwini olungenhla, isisombululo sokulondoloza kufanele silungiswe futhi;
• Kungakhathaliseki ukuthi yiziphi izimo lapho i-membrane igcinwe khona, i-membrane akufanele ishiywe yomile.
• Ukwengeza, ukugxila (iphesenti lokuhlushwa okukhulu) kwesisombululo se-formaldehyde esingu-0.2 ~ 0.3% nakho kungasetshenziswa njengesixazululo sokulondoloza. I-Formaldehyde ingumbulali wamagciwane anamandla kune-sodium bisulfite futhi ayinawo umoya-mpilo.
