Ngaba iimembrane ze-osmosis zinokuphinda zisetyenziswe emva kokutshintshwa?

Ngokuqhelekileyo, ii-membrane ze-osmosis zingacocwa.

I-Caustic soda kunye ne-hydrochloric acid zisetyenziswa ngokuqhelekileyo kwishishini, kunye nesixhobo esikhethekileyo sokucoca ngaphandle kwe-intanethi sisetyenziswa kwiqondo lokushisa elithile. Inkqubo ibandakanya ukuhlamba nge-caustic soda kuqala, emva koko nge-caustic soda, kunye nokucwina ixesha elide. Ubunzima benkqubo bungaphaya kobuchule babantu abaqhelekileyo.

Ngoko ke akukhuthazwa ukuba uhlambulule i-membrane ye-osmosis ye-reverse yendlu, njengoko inzima kakhulu kwaye akukho lula ukuyicoca.

Indlela yokucoca

1. Isicoci se-enzyme sisetyenziselwa ukunyanga inwebu, esebenza ngakumbi ngokuchasene nongcoliseko lwendalo, ngakumbi iprotheyini, i-oyile kunye nezinye izinto ezingcolisa umzimba. Isiphumo sokucoca singcono kwi-50-60 ℃. Ngokuqhelekileyo, emva kokusebenza iintsuku ezili-10 okanye isiqingatha senyanga, i-1% yokucoca i-enzyme isetyenziselwa ukucoca i-membrane phantsi koxinzelelo oluphantsi. Ngenxa yoxinaniso oluphantsi lwesicoci se-enzyme esisetyenzisiweyo, ixesha elide lokuntywiliselwa liyafuneka.
2. Isisombululo se-citric acid sisetyenziselwa ukuhlambulula ngokuqhubekayo okanye nge-cyclically i-membrane kunye ne-1% -2% ye-citric acid isisombululo samanzi phantsi koxinzelelo oluphezulu okanye oluphantsi, olunempembelelo yokucoca kakuhle kwi-Fe (OH) ye-3 yokungcola.
3. Isisombululo se-saline esigxininisiweyo sisebenza kakuhle ukucoca i-membrane kunye nokungcola okukhulu kwamalungu. Oku kungenxa yokuba isisombululo esiphezulu se-saline sinokunciphisa intsebenziswano phakathi kwe-colloids kunye nokukhuthaza ukubunjwa kwee-colloidal aggregates.
4. Isisombululo se-hydrogen peroxide, umzekelo, ukuxutywa kwe-0.5L ye-30% ye-H2O2 kunye ne-12L yamanzi adibeneyo kwaye emva koko ukucoca umphezulu we-membrane, kusebenza ngokukodwa ngokuchasene nongcoliseko lwendalo.
5. I-emulsion yamanzi e-soluble iyasebenza kakhulu ekucoceni iimbumba ezingcolileyo ngeoli kunye ne-iron oxide, ngokuqhelekileyo ukucoca i-30-60 imizuzu.
6. Eyona ndlela ilula yokucoca ngokomzimba kukusebenzisa uxinzelelo oluphantsi kunye nokuhamba okuphezulu ngokukhawuleza kwe-membrane ukutyhutyha kwamanzi kwimizuzu engama-30, enokubuyisela ukunyanzeliswa kwenwebu ukuya kwinqanaba elithile. Nangona kunjalo, ngokuhamba kwexesha, ukunyanzeliswa kuyancipha. Ngaphandle koko, umxube wamanzi kunye nomoya ungasetyenziselwa ukucoca umphezulu we-membrane phantsi koxinzelelo oluphantsi lwemizuzu eyi-15. Le ndlela isebenzayo ekucoceni i-membrane eziye zangcoliswa okokuqala ngezinto eziphilayo.

Ngaba ukho umgangatho othile wokutshintsha iimbrane ze-osmosis ezingasemva?

Ngokuqhelekileyo, emva kwexesha lokusetyenziswa, ukuveliswa kwamanzi kwi-membrane kuya kuncipha, uxinzelelo lwemveliso yamanzi luya kwanda, kwaye ukuqhutyelwa kwe-membrane kuya kuchaphazeleka. Xa ezi ngxaki zisenzeka, inwebu yakho inokucocwa okanye itshintshwe.

Ukuba uxinzelelo kunye nokuveliswa kwamanzi kwi-membrane ye-osmosis e-reverse emva kokucoca ihlangabezana neemfuno, kwanele, kodwa i-conductivity ngokubanzi ayinciphisi ngaphandle kokuba i-membrane ingcoliswe kakhulu yi-organic matter, kuba ubukhulu be-pore buyanda ngokuhlamba, kwaye kungakhathaliseki ukuba luhlobo luni lwesisombululo esisetyenzisiweyo, ukuveliswa kwamanzi kunye noxinzelelo emva kokucoca akukwazi ukufana ne-membrane entsha.

Sula inwebu entsha

1. Emva kokufaka amacandelo e-membrane, inkqubo entsha kufuneka ihlanjululwe ngokucokisekileyo ukuze isuse ngokucokisekileyo nakuphi na ukungcola okushiyekileyo, i-solvents, kunye nolwelo olukhuselayo kwinkqubo.
2. Xa usebenzisa amanzi avelisiweyo ukusela, kufuneka ihlanjwe ubuncinane iiyure ezingama-24.
3. Ngaphambi kokuqala inkqubo, ivalve yamanzi egxininisiweyo kufuneka igcinwe ivulekile ngokupheleleyo. Emva kokuba inkqubo iqalisiwe, ivalve yamanzi egxininisiweyo ingavalwa ngokuthe ngcembe kwaye ivalwe ngokukhawuleza ukufezekisa izinga lokubuyisela. Akuvumelekanga ngokungqongqo ukuqala izixhobo xa i-valve yamanzi egxininisiweyo ivaliwe.
4. Ngexesha lokusebenza kwesixokelelwano, iivalvu kumbhobho wokuvelisa amanzi akufunekanga zivalwe nangaliphi na ixesha (kuquka ukuqala kwangaphambili, ukusebenza kwesiqhelo, ukugungxulwa, kunye nokucocwa kweekhemikhali zesixokelelwano).
5. Ngaphambi kokusebenza koxinzelelo oluphezulu, yenza uxinzelelo oluphantsi lokugungxula ngesixhobo sokuqala esithambileyo okanye ummiselo wesantya esiguqukayo sokukhupha umoya.
