Kwete. Ultrafiltration (UF) uye reverse osmosis (RO) masisitimu ekurapa mvura ane simba uye anoshanda, asi UF yakasiyana neRO nenzira dzinoverengeka dzakakosha:
Inosefa zvinhu zvakasimba/zvidimbu zvidiki kusvika 0.02 microns, kusanganisira mabhakitiriya. Haikwanise kubvisa zvicherwa zvakanyungudutswa, TDS nezvinhu zvakanyungudutswa mumvura.
Gadzira mvura kana uchida - hapana matangi ekuchengetera anodiwa
Hapana mvura inoraswa inogadzirwa (inochengetedza mvura)
Inoshanda zvakanaka pamagetsi akaderera - hapana magetsi anodiwa
Ndeupi musiyano uripo pakati pe ultrafiltration ne reverse osmosis?
Rudzi rwetekinoroji yeMembrane
Kusvina kwemvura zvakanyanya (ultrafiltration) kunobvisa zvidimbu nezvinhu zvakasimba chete, asi kunoita izvi nepadiki diki; saizi yeganda remvura iri 0.02 microns. Kana tichitarisa kuravira, kusvina kwemvura zvakanyanya (ultrafiltration) kunochengetedza zvicherwa, izvo zvinokanganisa kuravira kwemvura.
Reverse osmosis inobvisa zvese zviri mumvura, kusanganisira zvicherwa zvakawanda zvakanyungudutswa nezvinhu zvakasimba zvakanyungudutswa. RO membranes imembranes dzinopinda mumvura dzine saizi yepore inosvika 0.0001 microns. Saka, mvura yeRO inenge "isina hwema" nekuti haina zvicherwa, makemikari, nezvimwe zvinhu zveorganic ne inorganic.
Vamwe vanhu vanoda mvura yavo kuti ive nemaminerari (nerubatsiro rweUF), vamwe vanoda kuti mvura yavo ive yakachena chose uye isina hwema (nerubatsiro rweRO).
Kusvina kwemagetsi zvakanyanya (ultrafiltration) kune membrane yefiber isina chinhu, saka ifirita yemagetsi ine mwero wepamusoro-soro inovhara zvidimbu nezvinhu zvakasimba.
Reverse osmosis inzira inoparadzanisa mamorekuru. Inoshandisa semi-permeable membrane kuparadzanisa inorganics ne inorganics dzakanyungudutswa kubva kumamorekuru emvura.
MUNAmvura yegungwa/Ramba
Kusefa kwemvura zvakanyanya (Ultrafiltration) hakuburitse mvura yakasviba (tsvina) panguva yekusefa*
Mu reverse osmosis, pane kupfapfaidzwa kwemvura kuburikidza ne membrane. Izvi zvinoreva kuti rwizi rwemvura (mvura inoyerera/yakagadzirwa) runopinda mutangi rekuchengetera uye rwizi rwemvura ine tsvina yese ne inorganics yakanyungudutswa (tsvina) runopinda mu drain. Kazhinji, pa galoni rimwe nerimwe re reverse osmosis rinogadzirwa, magaroni matatu anotumirwa ku drain.
Isa
Kuisa sisitimu ye reverse osmosis kunoda nzira dzinoverengeka dzekubatanidza: mitsetse yemvura, mitsetse yekuburitsa mvura yakasviba, matangi ekuchengetera, uye mapombi emhepo.
Kuisa sisitimu yekusefa mvura zvakanyanya ine ma membrane anokweshwa (tekinoroji yemazuva ano yekusefa mvura zvakanyanya*) inoda nzira dzinoverengeka dzekubatanidza: tambo yekudyisa, tambo yekudhonza mvura kuti isuke ma membrane, uye pombi yemvura yekunwa yakatsaurirwa (nzira dzekushandisa mvura yekunwa) kana tambo yekubuditsa mvura (nzira dzekushandisa mumba mese kana dzekutengesa).
Kuti uise sisitimu ye ultrafiltration isina ma membrane anogwamba kusukurudzwa, ingobatanidza sisitimu kune tambo yekugovera chikafu uye pombi yakatsaurirwa (mvura inonwiwa) kana tambo yekuburitsa mvura (nzvimbo dzese dzekugara kana dzekutengeserana).
Ndeipi iri nani, RO kana UF?
Reverse osmosis uye ultrafiltration ndiwo masisitimu anoshanda uye ane simba aripo. Pakupedzisira, ndeipi iri nani isarudzo yako pachako zvichienderana nemamiriro emvura yako, zvaunofarira, nzvimbo, chishuwo chekuchengetedza mvura, kumanikidzwa kwemvura, nezvimwewo.
Ndiyo RO yekuchenesa mvura uye Muchina wekuchenesa mvura weUF nekuda kwesarudzo yako.
