• Idatha eyisisekelo ye-reverse osmosis membrane

Izinga lokwenqatshwa kukasawoti: Izinga lokukhipha usawoti emanzini le-RO membrane liye lanqunywa ngesikhathi sokukhiqizwa kwalo, futhi izinga lokukhishwa kukasawoti emanzini lincike ekuminyeneni kongqimba oluncane lokukhipha usawoti emanzini olwelwesi olungaphezulu kwesici se-RO membrane, ungqimba oluminyene lokukhipha usawoti emanzini, izinga lokukhishwa kukasawoti emanzini liphakeme, kanye nokwehla kokukhiqizwa kwamanzi. Izinga lokukhipha usawoti ku-RO membrane yezinto ezihlukene linqunywa ikakhulukazi ukwakheka nesisindo samangqamuzana wento, izinga lokukhipha usawoti kuma-ion ane-valent ephezulu nama-ion ayinkimbinkimbi e-monovalent lingadlula ama-99%, kanye nezinga lokukhipha usawoti emanzini anosawoti afana ne-sodium ion, i-potassium ion, ne-chloride ions liphansi kancane, kodwa futhi lingadlula, izikhathi zokuhlanza zamakhemikhali ezingaphansi kuka-98%. izinga lokukhipha usawoti emanzini olwelwesi lwe-RO) Izinga lokususwa kwezinto eziphilayo ezinesisindo se-molecule enkulu kuno-100 lingase libe ngaphezu kwama-98%, kodwa izinga lokususwa kwezinto eziphilayo ezinesisindo se-molecular esingaphansi kwe-100 liphansi.

Indlela yokubala yezinga lokwenqatshwa kukasawoti kanye nokungena kukasawoti ku-membrane ye-RO:

Ukungena kukasawoti ku-membrane ye-RO = Ulwelwesi lwe-RO lugcwala ukugxila / ukugcwala kwamanzi okunomthelela × 100%

Izinga lokukhipha usawoti ku-membrane ye-RO = (okuqukethwe kukasawoti emanzini agcwele / okuqukethwe kukasawoti wamanzi anamandla we-1-RO membrane) × 100%

Ukukhiqizwa Kwamanzi: GPD = Amagalani (US)/Ngosuku, GFD = Amagalani (US)/unyawo lwesikwele ngasinye/ngosuku

Isivuno samanzi se-RO membrane - sibhekisela kumthamo wokukhiqiza amanzi wesistimu ye-RO, okungukuthi, inani lamanzi adlula kulwelwesi lwe-RO ngeyunithi yesikhathi, ngokuvamile evezwa ngamathani ngehora noma amagalani ngosuku. 1 ilitha (US) = 3.785 amalitha, 1 cubic meter = 264.2 amalitha (US).

I-permeability ye-membrane ye-RO nayo iyinkomba ebalulekile yesivuno samanzi se-RO membrane element. Isho isilinganiso sokugeleza kwe-permeate endaweni ngayinye yeyunithi yolwelwesi, ngokuvamile evezwa ngamalitha ngonyawo lwesikwele ngosuku (GFD). Izinga lokugeleza kwe-osmotic eleqile lizoholela ekusheshisweni kwezinga lokugeleza kwamanzi elibheke phezulu kulwelwesi lwe-RO, okuzokwandisa ukonakala kolwelwesi.

Ingcindezi (ingcindezi yokusebenza ephezulu): 1 kg ingcindezi = ibha engu-1 ≈ 14.5 psi = ikhanda 10m (ipompo)

I-PSI (Amaphawundi ngeyintshi yesikwele) iyiyunithi yokulinganisa. U-P ubhekisela kuphawundi, u-S ubhekisela kusikwele, ngibhekisela kumayintshi, futhi i-United States isetshenziselwa ukusebenzisa i-psi njengeyunithi, okusho ukuthi amandla ephawundi ngeyintshi yesikwele.

Ingcindezi yokusebenza yamalwelwesi e-RO ivamise ukuba phakathi kuka-2-20MPa, kuya ngezici ezifana nohlobo, usayizi, impahla, kanye nekhwalithi yamanzi yento yolwelwesi. Ngokuvamile, ukuphakama kwengcindezi yokusebenza kwe-membrane ye-RO, kuyanda ukusebenza kahle kokukhipha usawoti emanzini, kodwa futhi kwandisa ingozi yokugqokwa kwezakhi kanye nokonakala kolwelwesi. Ngakho-ke, ingcindezi yokusebenza ye-membrane ye-RO idinga ukulawulwa ngaphakathi kwebanga elifanele ukuze kuqinisekiswe ukuzinza nokuphila kwayo

Ekusetshenzisweni okungokoqobo, ingcindezi yokusebenza ye-membrane ye-RO idinga ukulungiswa ngokuya ngekhwalithi yamanzi kanye nezidingo zokwelashwa. Isibonelo, ekukhishweni kukasawoti emanzini olwandle, ukucindezela kokusebenza kolwelwesi lwe-RO kuvamise ukuba phakathi kuka-5-10MPa ukuze kuzuzwe ukusebenza kahle okuphezulu kokukhipha usawoti kanye nempilo ende. Ekulapheni kwamanzi angcolile ezimbonini, ulwelwesi lwe-RO lungasebenza ngaphansi kwezingcindezi eziphakeme ukuze lubhekane nekhwalithi yamanzi eyinkimbinkimbi kanye nokugxila okuphezulu kukasawoti.

Izinga Lokubuyisela: Ukubuyiselwa kolwelwesi lwe-RO - kubhekisela kumaphesenti amanzi okuphakelayo ohlelweni lwe-RO membrane aguqulwa abe yi-permeate noma i-permeate. Kunqunywa ngokwekhwalithi yamanzi anethonya afakwe ngaphambili kanye nezidingo zamanzi zohlelo lwe-RO. Izinga lokubuyisela uhlelo lwe-membrane ye-RO linqunywa ngesikhathi sokuklama.
Izinga lokubuyisela le-RO membrane = (izinga lokugeleza kwe-RO membrane / ukugeleza okunamandla) × 100%
