Uma usebenzisabuyisela ulwelwesi lwe-osmosisukwelapha amanzi aluhlaza, izinga lokubuyisela uhlelo lwe-membrane luyinkomba yokusebenza ebalulekile, ngokuvamile ethola ukunakwa okukhulu. Izinga eliphezulu lokubuyisela libonisa umthamo oqinile wokuphuma kwamanzi. Lithini izinga lokubuyiselwa kwesistimu ye-osmosis membrane? Okulandelayo incazelo enemininingwane nguHID RO MEMBRANE:
1. Lithini izinga lokutakula lolwelwesi lwe-osmosis reverse?
Izinga lokubuyisela libhekisela ephesentini lamanzi anamandla ohlelweni lwe-membrane aguqulwa abe amanzi omkhiqizo noma angenele, okunqunywa ikhwalithi yamanzi kanye nezidingo zamanzi ezinethonya ekusetshenzisweni kwangaphambili.
2. I-algorithm yesilinganiso sokutakula yesistimu yolwelwesi lwe-osmosis ehlehlayo
Izinga lokutholwa kwezinto ezivamile zolwelwesi lwe-osmosis elisemuva legatsha elilodwa lincike kwikhwalithi yamanzi anamandla, futhi izinga lokubuyisela lihluka kakhulu phakathi kuka-12% -50%. Izinga lokuthola kabusha lezinhlelo ezivamile zolwelwesi lwe-osmosis elibuyela emuva liyahlukahluka ukusuka ku-30% ukuya ku-90% kuye ngesikali sohlelo kanye nekhwalithi yamanzi aluhlaza.
Ifomula yokubala yezinga lokutakula imi kanje:
R%=Fp/Ff×100%
Kufomula:
Ff ---- buyisela ulwelwesi lwe-osmosis (uhlelo) izinga lokugeleza kwamanzi okungena ngaphakathi (m³/h)
Fp ---- Izinga lokugeleza kwamanzi le-reverse osmosis membrane (uhlelo) (m³/h)
R ---- Izinga lokutholwa kwe-reverse osmosis membrane (uhlelo)
Ngokunqunywa kwezinga lokuthola kabusha kwesistimu yolwelwesi lwe-osmosis ehlehlayo, ukuphindaphindwa kokugxiliswa kosawoti wamanzi aluhlaza kusistimu ye-osmosis ehlehlayo ingabalwa cishe. Ukuphindaphinda okugxilile kubhekisela ekuhlanganiseni kwento egxiliswe emanzini agxilile ohlelweni lwe-osmosis reverse kanye nokuqukethwe kwento efanayo emanzini okuphakelayo. Isilinganiso sibizwa nangokuthi i-concentration factor ye-reverse osmosis system. Ukwandisa i-concentration factor kungakhuphula izinga lokusebenzisa amanzi, kodwa kuzokhuphula ubulukhuni bamanzi futhi kubangele ukukala kalula. Ngakho-ke, ukuqonda i-concentration factor yesistimu kuyasiza kakhulu ukuthi siqonde ukungcoliswa nokungcoliswa kwe-waterside egxilile.
Ifomula yokubala ye-concentration factor yesistimu imi kanje:
CF=1/(1-R)
Kuphi: CF ---- i-concentration factor
R ---- Izinga lokubuyisela lesistimu ye-osmosis
Kungabonakala ukuthi i-concentration factor yamanzi aluhlaza iyanda njengoba izinga lokubuyisela likhuphuka, futhi lapho izinga lokubuyisela lingaphezu kwama-75%, ukuthambekela okwandayo kwesici sokuhlushwa kuba ngokushesha futhi kubonakale nakakhulu.
3. Ingabe izinga lokutholwa kwesistimu yolwelwesi lwe-osmosis ehlehlayo liphezulu ngangokunokwenzeka?
Uma izinga lokubuyisela esimweni liphezulu, amanzi ayancipha kancane kancane, kodwa izinga eliphezulu lokubuyisela kabusha lizobangela ukuwohloka kwekhwalithi yamanzi. Ukwandisa izinga lokubuyisela uhlelo kuzokwandisa umehluko wokugxila ezinhlangothini zombili ze-reverse osmosis membrane, okuholela ekwandeni kokuqukethwe kukasawoti emanzini omkhiqizo; ukwenyuka kwezinga lokuthola kabusha kuzophinde kwenze ukuthi umfutho oshayelayo wesistimu wehle, futhi ekugcineni kuholele ekwehleni kokukhiqizwa kwamanzi ohlelweni. Ukukhiqizwa kwamanzi kufanele kukhuphule ingcindezi yokusebenza kohlelo, okuholela ekwenyukeni kwezindleko zokusebenza kwesistimu. Ngakho-ke, izinga lokubuyisela kufanele libekwe ngokuvumelana nezimo zesistimu ye-osmosis ehlehlayo, hhayi ukuthi iphezulu kakhulu.
4. umkhawulo ophezulu wezinga lokutakula lesistimu yolwelwesi lwe-osmosis ehlehlayo
Izinga lokuthola kabusha akulona uhlobo lwe-osmosis ebuyela emuva, kodwa umphumela webhalansi yomklami wezidingo zekhwalithi yamanzi nosayizi wokugeleza kwamanzi okugxilile. Umkhawulo ophezulu wezinga lokutakula unqunywa izici ezimbili: ukuthambekela kokukalwa kwamanzi aluhlaza kanye nokuthambekela kwe-polarization yokuhlushwa ebusweni be-membrane. Ngakho-ke, ngaphambi kokusetha izinga lokubuyisela uhlelo, kuyadingeka ukuqinisekisa ukuthi usawoti ongancibiliki (ofana ne-CaCO3, CaSO4, BaSO4, SrSO4, SiO2, njll.) uzokwela phezu kolwelwesi oluphambene ne-osmosis. Uma umkhiqizo we-ion wosawoti ongancibiliki esixazululweni umkhulu kunomkhiqizo wawo wokuncibilika, imvula ingase ihle isuka esixazululweni, futhi izinga lokuthola kabusha elihambisana nokugcwala okukhulu kwamanzi agxilile aqinisekisa ukuthi akukho mvula umkhawulo ophezulu wezinga lokutholwa kwesistimu.
