Yenza iyunithi yakho ye-RO isebenze ngakumbi

• Iziseko zoNyango lwaManzi Indlela yokukhetha i-membrane ye-RO efanelekileyo

Ukukhethwa kunye nokuhambelana okufanelekileyo kwee-membrane ze-RO kugqiba amandla angundoqo wezixhobo ze-RO, kwaye kukho iintlobo ezininzi ze-RO membranes kwimarike, kwaye amaxabiso ahluke kakhulu. Ngaphandle kwenani elincinane kakhulu lezahlulo zeembrane ezikhethekileyo ezinexabiso elithile elongezelelweyo lobugcisa (ixabiso lokuphuphuma kwexabiso), amaxabiso eefilimu ze-RO zezinto eziqhelekileyo, iimodeli kunye neemeko zokusetyenziswa kwabaninzi abavelisi ziye zacaca kwaye zizinzile. Ngokuqhelekileyo, ixabiso le-membrane ye-RO ethunyelwa ngaphandle ibiza kakhulu kune-membrane ye-RO yasekhaya, kodwa ineenzuzo ezincinci malunga nokuzinza, ubomi benkonzo, izibonakaliso eziphambili (izinga le-desalination, isivuno samanzi, izinga lokubuyisela) njalo njalo.

• Idatha esisiseko ye-reverse osmosis inwebu

Izinga lokwaliwa kwetyuwa: Izinga lokukhutshwa kwetyuwa kwi-RO inwebu yesiqalelo sele limiselwe ngexesha lokwenziwa kwayo, kwaye izinga lokukhutshwa kwetyuwa kuxhomekeke kubuninzi bomaleko wokukhupha ityuwa ogqithiseleyo kumphezulu wento ye-RO inwebu, i-denser umaleko wokukhupha ityuwa, kokukhona uphezulu umlinganiselo wokukhupha ityuwa, kunye nokusezantsi kwemveliso yamanzi. Izinga lokukhupha ityuwa kwinwebu ye-RO kwizinto ezahlukeneyo limiselwa ikakhulu bubume kunye nobunzima bemolekyuli yento, isantya sokukhupha ityuwa kwiiyoni ezine-valent ephezulu kunye ne-monovalent ion ezintsonkothileyo zinokugqitha kuma-99%, kwaye isantya sokukhupha ityuwa yee-ion ze-sodium, i-ion ye-potassium, kunye ne-ion ye-chloride isezantsi kancinci, kodwa inokuphinda igqithe, amaxesha okucoca angaphezulu kwe-98% yeekhemikhali. izinga lokususa ityuwa kwi-membrane ye-RO) Izinga lokususwa kwezinto eziphilayo ezinobunzima bemolekyuli obukhulu kune-100 bunokuba ngaphezu kwe-98%, kodwa izinga lokususa izinto eziphilayo ezinobunzima be-molecular obungaphantsi kwe-100 buphantsi.

Indlela yokubala izinga lokwaliwa kwetyuwa kunye nokungena kwetyuwa kwi-RO membrane:

Ukunyanzeliswa kwetyuwa kwi-membrane ye-RO = I-membrane ye-RO ingena kwi-concentration / impembelelo yoxinzelelo lwamanzi × 100%

Isantya sokuchithwa kwetyuwa kwi-membrane ye-RO = (umxholo wetyuwa wamanzi atyhutyhayo / umxholo wetyuwa wamanzi anempembelelo ye-1-RO membrane) × 100%

Imveliso yaManzi: GPD = Iigaloni (US)/Ngosuku, GFD = Iigaloni (US)/ngesikwere sonyawo/ngosuku

Imveliso yamanzi ye-RO membrane - ibhekisela kumandla okuvelisa amanzi enkqubo ye-RO, oko kukuthi, ubungakanani bamanzi adlula kwi-membrane ye-RO kwiyunithi yexesha, ngokuqhelekileyo ibonakaliswe ngeetoni ngeyure okanye iigaloni ngosuku. I-gallon eyi-1 (i-US) = i-3.785 ilitha, i-1 cubic meter = i-264.2 iilitha (i-US).

I-permeability ye-membrane ye-RO nayo isalathisi esibalulekileyo semveliso yamanzi ye-RO membrane element. Ibhekiselele kwisantya sokuhamba kwe-permeate kwiyunithi yendawo ye-membrane, ngokuqhelekileyo ibonakaliswe ngeegaloni ngonyawo lwesikwere ngosuku (GFD). Isantya sokuhamba kwe-osmotic esigqithisileyo siya kukhokelela kwisantya esikhawulezayo sokuhamba kwamanzi kwi-perpendicular kumphezulu we-RO membrane, eya kwandisa ukungcola kwe-membrane.

Uxinzelelo (uxinzelelo oluphezulu lokusebenza): 1 kg uxinzelelo = 1 ibha ≈ 14.5 psi = intloko 10m (ipompo)

I-PSI (Iiponti nge-intshi nganye yesikwere) yiyunithi yomlinganiselo. U-P ubhekisa kwiponti, u-S ubhekisa kwisikwere, ndibhekisa kwi-intshi, kwaye iUnited States isetyenziselwa ukusebenzisa i-psi njengeyunithi, okuthetha ukuba amandla eponti nge-intshi nganye yesikwere.

Uxinzelelo olusebenzayo lwe-RO membranes luhlala luphakathi kwe-2-20MPa, kuxhomekeke kwizinto ezifana nohlobo, ubungakanani, izinto eziphathekayo, kunye nomgangatho wamanzi wento ye-membrane. Ngokubanzi, okukhona uphezulu uxinzelelo lokusebenza kwi-membrane ye-RO, kokukhona iphezulu ukusebenza kakuhle kwe-desalination, kodwa ikwanyusa umngcipheko wokunxitywa kwezinto kunye nokonakala kwenwebu. Ngoko ke, uxinzelelo olusebenzayo lwe-membrane ye-RO lufuna ukulawulwa ngaphakathi kwinqanaba elifanelekileyo ukuqinisekisa ukuzinza kunye nobomi

Kwizicelo ezisebenzayo, uxinzelelo lokusebenza lwee-membrane ze-RO kufuneka luhlengahlengiswe ngokwemigangatho yamanzi kunye neemfuno zonyango. Umzekelo, ekukhutshweni kwetyuwa emanzini olwandle, uxinzelelo olusebenzayo lwee-membrane ze-RO luhlala luphakathi kwe-5-10MPa ukufezekisa ukusebenza kakuhle kokukhupha ityuwa kunye nobomi obude. Kunyango lwamanzi amdaka kwimizi-mveliso, iimbrane ze-RO zinokusebenza kuxinzelelo oluphezulu ukumelana nomgangatho onzima wamanzi kunye noxinzelelo oluphezulu lwetyuwa.

Izinga loBuyiselo: I-RO yokubuyisela inwebu - ibhekisa kwipesenti yamanzi esondlo kwi-RO membrane system eguqulwa ibe yi-permeate okanye i-permeate. Kumiselwa ngokomgangatho wamanzi anempembelelo esele ifakwe ngaphambili kunye neemfuno zamanzi zenkqubo ye-RO. Izinga lokubuyisela inkqubo ye-membrane ye-RO inqunywe ngexesha loyilo.
Izinga lokubuyisela i-RO membrane = (izinga lokuhamba kwe-RO membrane / ukuhamba okunamandla) × 100%
