Reverse osmosis (RO) inoreva tekinoroji inonatsa mvura nekuisundidzira kuburikidza nechikamu chinopindika-permeable membrane pasi pekumanikidzwa kwakanyanya.Iyo RO membrane idenda rakatetepa rekusefa izvo zvinoparadzanisa zvinosvibisa uye yakanyungudika munyu kubva mumvura yekunwa.Iyo ine zvidimbu zvitatu, zvinoti polyester inotsigira webhu, micro-porous polysulfone interlayer uye yekupedzisira-yakaonda polyamide barrier layer.Aya ma membrane anogona kushandiswa mune ese maindasitiri maitiro uye nekuwana mvura inonwiwa.Mazuva ano, vari kuramba vachishandiswa pasi rose pakuchenesa mvura, sezvo maitiro eRO achipa nharaunda-inoshamwaridzika uye inodhura imwe nzira kune yakajairika nzira dzinoshandiswa senge distillation.Asi vanhu havasati vajaira zvizere mazwi anoshandiswa uye vanonyatsonzwisisa mutsauko uripo pakati pemhando dzero membranes.
Muchinyorwa chanhasi, tichazogovera muchidimbu mamwe emazwi anonyanya kushandiswa uye mutsauko pakati peRO membranes.Iyo HID membranes yakakamurwa nemhando ye membrane, kushandiswa kwe membrane, saizi, uye kuita.Pawebhusaiti yedu, membrane inonyanya kuiswa muzvikamu zvitatu uchishandisa membrane (GPD).Isu tinoisa yedu ro membranes zvichienderana nesaizi system yekushandisa uye GDP yavo.Kune ekugara ro membranes paHID, iyo GPD mutsara we50 - 200 uye inogona kubata kudzvanywa kwe65psi kusvika pa200psi.Isu tine mamodheru akakura kana aya mamembrane uye iwe unogona kutarisa yedu unit kubva kune yedu webhusaiti.Aya ma membrane akakodzera uye anokurudzirwa kushandisa mune madiki ro edzimba masisitimu.nekuda kweiyo yakaderera-kudzvanywa huwandu uye gpd mazinga.
Forcommercial ro membranes paHID, iyo GPD yakawanda ye200 - 1000 uye inogona kubata kumanikidzwa kwehuwandu hwe65psi kusvika kuhuwandu hwe200psi.Isu tine zvakare yakakura modhi yeaya membranes.Aya ma membranes akakodzera kushandiswa munzvimbo dzeveruzhinji kana zvivakwa zvehofisi, zvipatara, zvikoro, mafekitori, marabhoritari nekuti GPD yemamembrane aya inzvimbo yepamusoro kupfuura yekugara.Ivo vanowanzo shandiswa pakubvisa salination yemvura yepamusoro, pasi pemvura, pombi mvura, brackish ine salinity pasi pe2000ppm.Boka rechitatu ndiyo maindasitiri membranes, aya akakura muhukuru, GPD, uye akagadzirirwa mahombe masisitimu.Kubva pa780 - 11000 magaloni pazuva, aya anogona kushandiswa kubvisa munyu wemvura yegungwa uye nepamusoro-soro yemvura ine brackish uye anogona kubata kumanikidzwa kwe150psi kusvika pa600psi.Tichagovera ruzivo rwakadzama rwechikamu chimwe nechimwe muchinyorwa chedu chinotevera.
Mazwi akakosha anoshandiswa mune reverse osmosis
Kudzoreredza - iyo muzana ye membrane system yekudyisa mvura inobuda muhurongwa semvura yechigadzirwa kana "permeate".
Kurambwa - iyo muzana ye solute concentration yakabviswa kubva kune system feed mvura ne membrane.
Passage - iyo inopesana ne "kurambwa", ndima yacho iperesenti yezvakanyungudutswa (zvinosvibisa) mumvura yekudyisa inobvumidzwa kupfuura nemukati me membrane.
Kuyerera - Kuyerera kwekudya chiyero chemvura yekudyisa yakaunzwa kune membrane element kana membrane system, inowanzoyerwa mumagaloni paminiti (gpm).
Concentrate flow - ndiwo mwero wekuyerera kwemvura isiri-permeated feed inobuda mu membrane element kana membrane system.
Flux - mwero wepermeate inotakurwa pachikamu chemembrane area, inowanzoyerwa mumagaloni paskweya tsoka pazuva (gfd) kana marita paskweya mita neawa (L/m2h).
Permeate - iyo yakanatswa chigadzirwa mvura inogadzirwa ne membrane system.
Total Dissolved Solids (TDS) - inowanzoratidzwa semg/lor ppm (zvikamu pamiriyoni).
