IMembrane entsha ye-RO ayisebenzi?

Kutheni i-RO Membrane entsha Ingasebenzi?Makhe sithethe ngezizathu kunye nezisombululo ezingezantsi:

1. Ubushushu bamanzi angaphakathi buphantsi kakhulu:
Ubushushu obuqhelekileyo bokusebenza kwe-reverse osmosis inwebu yi-25℃, kwaye imveliso yamanzi iya kuhla nge-3% ngalo lonke ixesha ubushushu behla ngedigri enye.Ukuba amaqondo obushushu angaphantsi kwe-0°C, amanzi akrwada ayaba ngumkhenkce kwaye ngokwendalo awakwazi ukuvelisa amanzi ngokuqhelekileyo.

2. Uxinzelelo lwamanzi okungena luphantsi kakhulu:
Umgaqo wokusebenza we-reverse osmosis inwebu kukucoca ngoxinzelelo.Ukuba impompo ye-booster isetyenziswe ixesha elide, uxinzelelo lwe-inlet luyehla, kwaye amanzi akrwada akakwazi ukuhlangabezana neemfuno, okubangela ukuba kungabikho manzi ngaphandle kwenkqubo ye-osmosis ebuyela umva.Ngokuqhelekileyo, uxinzelelo olusebenzayo lwe-membrane ye-osmosis eguqukayo kufuneka ifikelele kwi-4.14MPA.

3. I-pH enempembelelo
Iimodyuli ezahlukeneyo ze-membrane ze-RO zinoluhlu oluvumelekileyo lwe-pH, kwaye i-pH yamanzi anefuthe phantse ayinampembelelo kwimveliso ye-tater.Kodwa nangaphakathi koluhlu oluvumelekileyo, lunempembelelo enkulu kwizinga lokwaliwa kwetyuwa.Ngakolunye uhlangothi, ixabiso le-pH libuye libe nefuthe elithile kwi-conductivity yamanzi emveliso.Oku kungenxa yokuba i-membrane ye-osmosis eguqukayo ngokwayo iqulethe amaqela athile asebenzayo, kwaye ixabiso le-pH linokuchaphazela inwebu.Intsimi yombane phezu komhlaba ichaphazela ukufuduka kweeyoni.Ixabiso le-pH linempembelelo ngqo kwifom yokungcola kwimpembelelo.Ngokomzekelo, kwi-organic dissociable, izinga lokwala liyancipha ngokuhla kwe-pH.Ngakolunye uhlangothi, ngenxa yokuba i-CO2 echithwe emanzini ichaphazeleka kakhulu ngexabiso le-pH, xa ixabiso le-pH liphantsi, likhona ngendlela ye-CO2 enegesi kwaye ingena lula kwi-membrane ye-osmosis ebuyela emuva.Ngoko ke, izinga lokugatya ityuwa liphantsi xa ixabiso le-pH liphantsi.Njengoko i-pH inyuka, i-CO2 ye-gaseous iguqulwa kwi-HCO-3 kunye ne-CO2-3 ion, izinga lokugatya ityuwa likhula ngokuthe ngcembe, kwaye izinga lokugatya ityuwa lifikelela phezulu phakathi kwe-pH 7.5 kunye ne-8.5.

4. Ugxininiso lwetyuwa olunempembelelo
Uxinzelelo lwe-Osmotic ngumsebenzi woxinzelelo lwetyuwa okanye i-organic matter emanzini.Ukuphakama kwetyuwa, uxinzelelo lwe-osmotic luyanda.Xa uxinzelelo lwe-inlet luhlala lufana, uxinzelelo lomnatha luya kuncipha kwaye ukuveliswa kwamanzi kuya kuncipha.Ukungena kwetyuwa kumlinganiselo wokuxinana kwetyuwa phakathi komphambili nasemva kwenwebu.Ukuphakama kwetyuwa kwimpembelelo, ukuhlukana okukhulu koxinzelelo, kunye nokunyuka kwetyuwa kunyuka, okukhokelela ekunciphiseni izinga lokulahlwa kwetyuwa.Kwinkqubo efanayo, umxholo wetyuwa wamanzi wesondlo uhlukile, uxinzelelo lokusebenza kunye nemveliso ye-conductivity yamanzi nayo yahlukile.Ngalo lonke unyuso lwetyuwa yamanzi esondlo nge-100 ppm, uxinzelelo lwamanzi angenayo kufuneka lunyuke malunga ne-0.007 MPa.Ngelo xesha, ngenxa yokunyuka kokuxininisa, imveliso yamanzi conductivity Kwakhona kwanda ngokufanelekileyo.

5. Ukuvaleka konyango lwangaphambili:
Iimbrane ze-osmosis ezibuyela umva zineemfuno eziphezulu zokuthathwa kwamanzi, kwaye izixhobo ezifanelekileyo zonyango lwangaphambili, njengezihluzi zesanti ye-quartz, izihluzi zokhuseleko, njl.njl., zihlala zongezwa phambi kwezinto ze-membrane.Ukuba isetyenziswe ixesha elide, isixhobo sonyango lwangaphambili sinokuvaleka ngenxa yokungcola okugqithisileyo.Emva kokuvalwa, kuya kubakho ukuhla okuthile kwimveliso yamanzi.Xa ukungcola kwangaphambili kuvaliwe ngokupheleleyo, amanzi akrwada awakwazi ukungena kwi-membrane ye-osmosis ebuyela emva kwi-pretreatment, emva koko i-osmosis engasemva I-membrane iya kubonakala kuthiwa akukho manzi.

6. Ivalve yokukhangela ivaliwe:
Ngethuba lokusetyenziswa, i-valve yokutshekisha inokuthi ivalwe ngokungcola.Unokuthatha i-valve yokukhangela ukuba ukhangele ukuba ukuveliswa kwamanzi kwenkqubo kuye kwanda kakhulu.Ngokuqhelekileyo, ithuba lokuvala ivalve yokukhangela lincinci.

7. I-membrane ye-osmosis engasemva ivalwe bubumdaka:
Ukongeza kunyango lwangaphambili kunokuvaleka, iimbrane ze-osmosis ezingasemva zinokuvaleka.Amanzi akrwada aqulethe ukungcola okuninzi.Ngesiqhelo isixhobo sonyango lwangaphambili sinokuhluza uninzi lokungcola ukwenza amanzi anempembelelo ahlangabezane neemfuno ezisemgangathweni ze-osmosis ebuyela umva.Nangona kunjalo, ezinye iinkqubo zonyango lwangaphambili ziyilwe ngokungekho ngqiqweni, ezikhokelela kukungcola okufana ne-organic, i-chlorine yasimahla, kunye nezinto eziqinileyo ezinqunyanyisiweyo.Ukungena ngaphakathi kwi-membrane element, kubangela ukuvaleka kwento ye-membrane.Xa ukungcola kuthintela ngokupheleleyo ubungakanani be-membrane pore, akuyi kubakho mveliso yamanzi.

8. Inkqubo yesihluzi sasemva ivaliwe:
Kwinkqubo yokusetyenziswa, amanyathelo okukhusela afanelekileyo ahlala eyongezwa emva kwe-membrane ye-osmosis ejikelezayo ukukhusela amanzi emveliso ukuba angachatshazelwa zezinye izinto, ezifana ne-activated carbon filtration, i-filtration echanekileyo, njl. ikwachaphazela i-osmosis engasemva yokuveliswa kwamanzi kwenkqubo.
