I-Reverse Osmosis (RO) ibhekisela kubuchwepheshe obuhlanza amanzi ngokuwaphusha kulwelwesi olungapenyeleka ngaphansi kwengcindezi ephezulu. Ulwelwesi lwe-RO luwungqimba oluncane lwezinto zokuhlunga ezihlukanisa ama-ejenti angcolisayo nosawoti oncibilikisiwe emanzini okuphuza. Iqukethe izendlalelo ezintathu, okuyiwebhu esekela i-polyester, i-micro-porous polysulfone interlayer kanye ne-ultra-thin polyamide barrier layer. Lezi zingqimba zingasetshenziswa kuzo zombili izinqubo zezimboni nasekutholeni amanzi aphuzwayo. Kulezi zinsuku, aya ngokuya esetshenziswa emhlabeni wonke ukuhlanzwa kwamanzi, njengoba inqubo ye-RO inikeza enye indlela evumelana nemvelo futhi engabizi kakhulu kumasu asetshenziswa ngokuvamile afana nokuhluza. Kodwa abantu abakawajwayeli ngokugcwele amagama asetshenziswayo futhi bawuqonde ngokugcwele umehluko phakathi kwezinhlobo zama-membrane e-ro.
Esihlokweni sanamuhla, sizokwabelana kafushane ngamanye amagama asetshenziswa kakhulu nokuthi umehluko phakathi kwe-RO membranes. Ama-membrane e-HID ahlukaniswa ngohlobo lolwelwesi, ukusetshenziswa kolwelwesi, usayizi, nokusebenza. Kuwebhusayithi yethu, ulwelwesi luhlukaniswa ikakhulukazi izigaba ezintathu kusetshenziswa i-membrane (GPD). Sihlukanisa ulwelwesi lwethu lwe-ro ngokuya ngosayizi wesistimu yohlelo lokusebenza kanye nebanga le-GDP yabo. Ngolwelwesi lwe-ro lwezindawo zokuhlala e-HID, i-GPD ibanga elingu-50 - 200 futhi ingakwazi ukuphatha ingcindezi ibanga elingu-65psi ukuya ku-200psi. Sinamamodeli abanzi noma lezi zindwangu futhi ungabheka iyunithi yethu kuwebhusayithi yethu. Lawa ma-membrane afanelekile futhi anconywa ukuthi asetshenziswe ezinhlelweni ezincane zasendlini. ngenxa yobubanzi bengcindezi ephansi kanye namazinga e-gpd.
Ngoba commercial ro membranes at HID, ububanzi be-GPD obungu-200 - 1000 futhi bungakwazi ukuphatha ububanzi bengcindezi obungu-65psi ukuya kubukhulu obungu-200psi. Siphinde sibe nemodeli ebanzi yalezi zimbotshana. Lezi zingqimba zilungele ukusetshenziswa ezindaweni zomphakathi noma ezakhiweni zamahhovisi, izibhedlela, izikole, amafekthri, amalabhorethri ngoba iGPD yalezi zimbotshana inamandla amakhulu kunezindawo zokuhlala. Avame ukusetshenziselwa ukukhipha usawoti emanzini angaphezulu, amanzi angaphansi komhlaba, amanzi ampompi, abrackish anosawoti ngaphansi kuka-2000ppm. Iqembu lesithathu yizimboni zezimboni, lezi zikhulu ngosayizi, i-GPD, futhi zenzelwe amasistimu amakhulu. Kusuka ku-780 - 11000 amalitha ngosuku, lawa angasetshenziselwa ukukhipha usawoti emanzini olwandle kanye namanzi anebrackish agxilile futhi angakwazi ukumelana nengcindezi engu-150psi ukuya ku-600psi ephezulu. Sizokwabelana ngolwazi oluthe xaxa ngesigaba ngasinye esihlokweni sethu esilandelayo.
Amagama ayisihluthulelo asetshenziswe ku-osmosis ephambene
Ukubuyisela kabusha - iphesenti lamanzi okuphakela kwesistimu ye-membrane avela ohlelweni njengamanzi omkhiqizo noma "i-permeate".
Ukwenqatshwa - iphesenti lokuhlushwa kwe-solute elikhishwe emanzini okuphakelayo kwesistimu ngolwelwesi.
Iphaseji - okuphambene nokuthi "ukwenqatshwa", isiqephu singamaphesenti ezinto ezincibilikisiwe (ukungcola) emanzini okuphakelayo avunyelwe ukudlula kulwelwesi.
Ukugeleza - Ukugeleza kokuphakelayo izinga lamanzi okuphakelayo elethulwa engxenyeni yolwelwesi noma ohlelweni lolwelwesi, ngokuvamile olukalwa ngamalitha ngomzuzu (gpm).
Ukugeleza kwe-concentrate - izinga lokugeleza kwamanzi okuphakelayo okungagcwalisiwe aphuma engxenyeni yolwelwesi noma ohlelweni lolwelwesi.
I-Flux - isilinganiso se-permeate ethuthwa ngeyunithi ngayinye yendawo yolwelwesi, ngokuvamile ikalwa ngamalitha ngonyawo lwesikwele ngosuku (gfd) noma amalitha ngemitha yesikwele nehora (L/m2h).
I-Permeate - amanzi omkhiqizo ahlanziwe akhiqizwa uhlelo lwe-membrane.
I-Total Dissolved Solids (TDS) - ngokuvamile ichazwa ngokuthi mg/lor ppm (izingxenye ngesigidi).
