Abstract
Izakhi zolwelwesi lwe-Spiral-wound reverse osmosis zisetshenziswe kabanzi ekuhlanzeni amanzi asendlini okuvamise ukudinga izinga eliphezulu lokubuyisela amanzi.Ukukalwa kwe-Membrane kuseyisithiyo esinganqamuki esingase sonakalise ukusebenza kwezakhi zolwelwesi.Kulolu cwaningo, senze isiteshi sokuphakelayo senoveli esinesiqondiso sokugeleza kwe-diagonal, lapho ukusebenza kwahlolwa khona ngokuhlolwa kokuhlunga ku-elementi ye-membrane yangempela kanye nomthelela wokucushwa kwesiteshi kwahlaziywa ngokuhlanganisa ukulingisa kwamandla oketshezi okubaliwe nendlela yokusabela kwendawo.Imiphumela yabonisa ukuthi i-elementi ye-membrane eneziteshi ze-diagonal-flow feed yenoveli ibonise ukugeleza kwamanzi okuphezulu kanye nezinga eliphansi lokuncipha kanye nokwenqatshwa kukasawoti okuphezulu kunaleyo evamile ene-axial flow direction.Ukuguqulwa kwendlela okugeleza ngayo amanzi kungase kwenyuse kakhulu isivinini sokugeleza okumaphakathi esiteshini, ngaleyo ndlela kuthuthukise ukudluliswa kobuningi futhi kunciphise ukuhlukaniswa okugxilile.Ukuze uthole ukubuyiselwa kwamanzi okuhlosiwe okungama-75% kanye nokugeleza kwamanzi okungu-~45 L/(m2·h), ukulungiselelwa okuphelele mayelana nezilinganiso zobubanzi bobubanzi nezimbobo ezincane endaweni yokungena/okuphumayo yamashaneli okuphakela kwe-diagonal-flow kuyaphakanyiswa ngaphakathi ububanzi be-20-43% no-5-10%, ngokulandelana.Isiteshi sokuphakelayo sokugeleza kwe-diagonal sinethuba elithembisayo lohlelo lokusebenza lokulawula ukukala kwe-membrane.
Amaphuzu avelele
• Ishaneli yokuphakelayo ye-diagonal-flow inoveli yathuthukiswa ukuze kutholwe ama-elementi e-RO membrane.
• Ukusebenza kwe-elementi ye-membrane kwathuthukiswa ngokuguquguquka okuphezulu nokwenqatshwa kukasawoti.
• Ishaneli yokuphakelayo kwe-diagonal-flow ingakhuthaza ukudluliswa kobuningi futhi inciphise ukukala kwe-membrane.
• Ishaneli ye-diagonal-flow feed iyathembisa uma ukugeleza kwamanzi kanye nezinga lokuthola kabusha liphezulu.
Ukushicilelwa kwemiphumela yocwaningo mayelana nobuchwepheshe be-membrane obuhlala isikhathi eside kumajenali aphezulu wamazwe ngamazwe kumelela impumelelo kubuchwepheshe bendabuko kanye nokuhlolwa kwemikhakha emisha, ngaleyo ndlela kwakha inzuzo eyinhloko yokuncintisana ye-Angel.Ngokuzayo, i-Angel Group Central Research Institute izoqhubeka nokuhlinzeka ngomfutho wesikhathi eside ngokusungula izinto zobuchwepheshe, iphishekele ngamandla ukuqanjwa kabusha kwezobuchwepheshe ukuze ifinyelele phezulu, futhi ithathe indawo ephakeme yemakethe yokusungula umkhiqizo ngobuchwepheshe bangempela.
