Abstract
Izinto ze-Spiral-wound reverse osmosis membrane ziye zasetyenziswa ngokubanzi kucoceko lwamanzi asekhaya adla ngokufuna izinga eliphezulu lokubuyiswa kwamanzi.Ukulinganiswa kweMembrane kuhlala kungumqobo ongathintekiyo onokuthi wonakalise ukusebenza kwezinto zemembrane.Kolu phononongo, siphuhlise itshaneli yesondlo yenoveli enendlela yokuqukuqela kwediagonal, apho umboniso waphononongwa ngovavanyo lokuhluza kwizinto zokwenyani zemembrane kunye neempembelelo zokusetyenzwa kwejelo zahlalutywa ngokudityaniswa kwe-computational fluid dynamics ukulinganisa kunye nendlela yokuphendula umphezulu.Iziphumo zabonisa ukuba i-membrane element enenoveli i-diagonal-flow feed channels ibonise ukushukuma kwamanzi okuphezulu kunye nesantya esisezantsi sokwehla kunye nokwaliwa kwetyuwa ephezulu kunesiqhelo esinendlela yokuhamba kwe-axial.Ukuguqulwa kwendlela yokuhamba kwamanzi kunokunyusa kakhulu i-avareji ye-avareji yesantya sokuqukuqela kumjelo, ngaloo ndlela kuphuculwe ukugqithiselwa kobuninzi kunye nokunciphisa i-polarization yoxinaniso.Ukufumana amanzi ekujoliswe kuwo nge-75% kunye nokuhamba kwamanzi ~ 45 L/(m2·h), ulungelelwaniso olufanelekileyo malunga nomlinganiselo wobubanzi bobubanzi kunye nemingxuma emxinwa kwi-inlet/outout ye-diagonal-flow flow channels iyacetyiswa ngaphakathi uluhlu lwe-20-43% kunye ne-5-10%, ngokulandelanayo.Umjelo we-diagonal-flow feed channel unethuba elithembisayo lesicelo sokulawula ukulinganisa kwe-membrane.
Iimbalasane
• Ijelo elitsha le-diagonal-flow feed liphuhliselwe i-RO membrane element.
• Ukusebenza kwe-membrane element kuye kwaphuculwa ngokuguquguquka okuphezulu kunye nokulahlwa kwetyuwa.
• Umjelo we-diagonal-flow feed unokukhuthaza ukuhanjiswa kobuninzi kunye nokunciphisa ukulinganiswa kwe-membrane.
• Umjelo we-diagonal-flow feed uyathembisa xa ukuqukuqela kwamanzi kunye nezinga lokuchacha liphezulu.
Ukupapashwa kweziphumo zophando malunga neteknoloji ye-membrane ehlala ixesha elide kwiijenali eziphezulu zamazwe ngamazwe ibonisa impumelelo kubuchwepheshe bendabuko kunye nokuphononongwa kwemimandla emitsha, ngaloo ndlela kwakhiwa inzuzo engundoqo yokhuphiswano lwe-Angel.Kwixesha elizayo, i-Angel Group Central Research Institute iya kuqhubeka nokubonelela ngenkqubo yexesha elide kunye nokuveliswa kwezinto ezintsha zobuchwepheshe, ilandele ngamandla iteknoloji entsha ukuze ibambe, kwaye ithathe indawo ephakamileyo yemarike yokuveliswa kwezinto ezintsha kunye nobuchwepheshe bokuqala.
