Ko reverse osmosis membranes inogona kushandiswazve mushure mekutsiviwa?

Kazhinji kutaura, reverse osmosis membranes inogona kucheneswa.

Caustic soda uye hydrochloric acid inowanzo shandiswa muindasitiri, uye yakasarudzika yekuchenesa dhizaini inoshandiswa pane imwe tembiricha. Maitiro acho anosanganisira kugeza necaustic soda kutanga, ipapo necaustic soda, uye kunyura kwenguva yakareba. Kuoma kwemaitiro acho kunodarika hunyanzvi hwevanhuwo zvavo.

Saka hazvikurudzirwe kuchenesa imba reverse osmosis membrane, sezvo yakanyanya kunetsa uye isiri nyore kuchenesa.

Kuchenesa nzira

1. Enzyme detergent inoshandiswa kurapa membrane, iyo inonyanya kushanda pakurwisa kusvibiswa kwehupenyu, kunyanya mapuroteni, mafuta uye zvimwe zvinosvibisa. Iyo yekuchenesa maitiro iri nani pa50-60 ℃. Kazhinji, mushure mekushanda kwemazuva gumi kana hafu yemwedzi, 1% enzyme detergent inoshandiswa kuchenesa membrane pasi pekumanikidzwa kwakaderera. Nekuda kwekushomeka kweiyo enzyme detergent inoshandiswa, nguva yakareba yekunyudza inodiwa.
2. Citric acid solution inoshandiswa kuenderera mberi kana cyclically sukurudza membrane ne 1% -2% citric acid aqueous solution pasi pepamusoro kana pasi pekumanikidzwa, iyo ine yakanaka yekuchenesa mhedzisiro paFe (OH) 3 kusvibiswa.
3. Concentrated saline solution inoshanda pakuchenesa mamembrane nekusvibiswa kwemakumbo kwakanyanya. Izvi zvinodaro nekuti yakakwira concentration saline solution inogona kunetesa kudyidzana pakati pemacolloid uye kukurudzira kuumbwa kwemacolloidal aggregates.
4. Hydrogen peroxide solution, semuenzaniso, diluting 0.5L ye30% H2O2 ne12L yemvura yakasvibiswa uyezve kuchenesa membrane pamusoro, inonyanya kushanda pakurwisa kusvibiswa kweorganic.
5. Mvura yakasvibiswa emulsion inoshanda zvikuru pakuchenesa membrane yakasvibiswa nemafuta uye iron oxide, kazhinji kuchenesa kwemaminitsi makumi matatu-60.
6. Iyo yakapfava yekuchenesa yemuviri nzira ndeye kushandisa yakaderera-kudzvanywa uye yakakwirira kuyerera nekukurumidza membrane permeation mvura inoyerera kwemaminetsi makumi matatu, iyo inogona kudzoreredza permeability ye membrane kusvika pamwero wakati. Nekudaro, nekufamba kwenguva, iyo permeability ichiri kuderera. Neimwe nzira, musanganiswa wemvura nemhepo unogona kushandiswa kutsvaira membrane pamusoro pasi pekumanikidzwa kwakaderera kwemaminetsi gumi nemashanu. Iyi nzira inoshanda pakuchenesa mamembrane ayo akatanga asvibiswa neorganic matter.

Pane here chiyero chaicho chekutsiva reverse osmosis membranes?

Kazhinji kutaura, mushure menguva yekushandiswa, kugadzirwa kwemvura kwe membrane kuchaderera, kumanikidza kwekugadzira mvura kuchawedzera, uye conductivity ye membrane ichakanganiswawo. Kana matambudziko aya aitika, membrane yako inogona kucheneswa kana kutsiviwa.

Kana kudzvinyirirwa uye kugadzirwa kwemvura kweiyo reverse osmosis membrane mushure mekuchenesa inosangana nezvinodiwa, zvakakwana, asi conductivity kazhinji haina kuderera kunze kwekunge membrane yakasvibiswa zvakanyanya ne organic matter, nekuti saizi yepore inowedzera nekugezwa, uye zvisinei kuti ndeipi mhinduro inoshandiswa, kugadzirwa kwemvura uye kudzvanywa mushure mekuchenesa hakugone kufanana ne membrane nyowani.

Sukurudza membrane itsva

1. Mushure mekuisa iyo membrane zvikamu, iyo nyowani system inoda kunyatsogezwa kuti ibvise zvachose chero tsvina yasara, zvinonyungudutsa, uye zvinwiwa zvinodzivirira kubva kuhurongwa.
2. Paunenge uchishandisa mvura inogadzirwa pakunwa, inoda kugezwa kweanenge maawa makumi maviri nemana.
3. Usati watanga hurongwa, vheji yemvura yakanyanyisa inofanira kuchengetwa yakazaruka zvakakwana. Mushure mekunge hurongwa hwatangwa, vheji yemvura yakadzika inogona kuvharwa zvishoma nezvishoma uye zvishoma nezvishoma kuti iwane chiyero chekudzorera. Izvo zvinorambidzwa zvachose kutanga midziyo kana iyo yakanyanyisa mvura valve yakavharwa.
4. Munguva yekushanda kwehurongwa, mavharuvhu ari papombi yekugadzira mvura haafanire kuvharwa chero nguva (kusanganisira pre-kutanga, muitiro wekushanda, kuchenesa, uye kuchenesa makemikari ehurongwa).
5. Usati waita kuvhiyiwa kwepamusoro-soro, ita yakaderera-kudzvanya kuburikidza neyakapfava yekutanga meshini kana inosiyana frequency yekumhanyisa regulation kuburitsa mweya.
