Izikhokelo zokusetyenziswa ngokufanelekileyo kwee-RO Reverse Osmosis Membrane

1. Isilumkiso! Le misebenzi ingafanelekanga inokonakalisa ngokuthe ngqo i-RO reverse osmosis membrane

Ukusebenza kwee-RO reverse osmosis membranes kubonakala kuzinzile, kodwa ukungahoywa okuncinci kokusebenza kunokukhokelela ekusileleni kwangethuba, ikakhulu kugxilwe kwiindidi ezintathu zemiba.

Igesi eseleyo engakhutshwa ngokupheleleyo phantsi koxinzelelo oluphezulu inokubangela ukuba "isando somoya" sonakalise i-membrane

Xa igesi eseleyo ngaphakathi kwesixhobo isebenza phantsi kweemeko zoxinzelelo oluphezulu, inokudala "isiphumo sehamile yamanzi," esichaphazela ngokuthe ngqo izinto ze-membrane kwaye sibangele umonakalo womzimba. Le meko idla ngokuvela kwiimeko ezimbini:

Xa izixhobo ziqala kwakhona, igesi ayikasuswa ngokupheleleyo: Emva kokucoca izixhobo, qalisa kwakhona ukusebenza. Ukuba umoya awukhutshwanga ngokupheleleyo kwaye uxinzelelo lunyuswa ngokukhawuleza, igesi eseleyo iya kuchaphazela ngamandla i-membrane. Inkqubo echanekileyo kukusebenza ngoxinzelelo oluphantsi lwe-2 ~ 4 bar kuqala, kwaye wonyuse uxinzelelo kancinci kancinci xa kungekho maqamza abonakalayo kwimitha yokuhamba (okubonisa ukususwa komoya ngokupheleleyo).

Ukuvaleka kakuhle kwemibhobho kuvumela ukungena komoya: Ukuba unxibelelwano phakathi kwezixhobo zangaphambi konyango (umz., i-microfilter) kunye nepompo yoxinzelelo oluphezulu luyavuza okanye aluvalwanga kakuhle, ukungonelanga kwamanzi angaphambi konyango (umz., ukuhamba okunciphileyo ngenxa yokuvaleka kwe-microfilter) kudala i-vacuum kwipayipi, nto leyo ekhokelela ekufunxeni umoya. Izisombululo ziquka ukucoca okanye ukutshintsha i-microfilter evalekileyo ngokukhawuleza, ukuhlola nokulungisa imibhobho evuzayo, kunye nokuqinisekisa ukuba akukho moya ungena ngexesha lokusebenza.

2. Indlela engalunganga yokuvala ikhokelela ekukhuleni kwefilimu kunye nongcoliseko

Abantu abaninzi bakholelwa ukuba "ukucima = ukucima ngoko nangoko," kodwa oku kunokushiya iingozi ezifihlakeleyo kwiimembrane ze-RO, ikakhulu kubandakanya imiba emibini:

Ukunciphisa uxinzelelo ngaphandle kokuhlamba kunokukhokelela ekunyukeni kwe-concentrate kwicala: Ngexesha lokusebenza kwe-RO membrane, uxinzelelo lwetyuwa engaphiliyo kwicala le-concentrate luphezulu kakhulu kunolo lukwi-feed water. Ukuba uxinzelelo luyancipha ngokukhawuleza xa luvaliwe ngaphandle kokuhlamba kakuhle, iityuwa ezingaphiliyo kwi-concentrate ziya kunamathela kumphezulu we-membrane, ekugqibeleni zenze ii-scale deposits ezivala ii-membrane pores kwaye zinciphise ukusebenza kakuhle kokucoca ngokuhamba kwexesha.

Hlamba ngamanzi aneekhemikhali: Abanye abasebenzisi bahlamba izinto ze-membrane ngamanzi aneekhemikhali ngaphambi kokucoca, into engacetyiswayo. Ngexesha lokungasebenzi kwezixhobo, iikhemikhali ezineekhemikhali zinokusabela kwi-membrane okanye zishiye amasalela angcolisa i-membrane, nto leyo echaphazela umgangatho wokungcola okulandelayo.

3. Ukungasebenzisi iintsholongwane ngokwaneleyo kunye nokugcinwa kwazo kungakhokelela ekubeni iintsholongwane "zihlale" kwi-membrane

Izinto ze-polyamide ezidityanisiweyo ziyindlela eqhelekileyo yokukhetha ii-membrane ze-RO, kodwa zineengxaki: ukumelana okuncinci ne-chlorine eseleyo. Ukuba izibulali-ntsholongwane ezifana ne-chlorine azifakwanga idosi efanelekileyo ngexesha lokusebenza, kunye nokungakhathalelwa ngokwaneleyo kongcoliseko lweentsholongwane, iintsholongwane kunye neentsholongwane emanzini ziya kwanda kumphezulu we-membrane, zenze ii-biofilms. Oku akugcini nje ngokuvalela ii-pores ze-membrane kodwa kukwakhokelela kungcoliseko lweentsholongwane emanzini aphumayo (isizathu esiyintloko samanqanaba eentsholongwane zamanzi acocekileyo angaphantsi komgangatho wabenzi abaninzi silapha).
