I-Seawater Desalination Membrane

I-Seawater Desalination Membrane

Incazelo:

Ukushoda kwamanzi wudaba lomhlaba wonke oludinga izixazululo ezintsha. Ukukhishwa kukasawoti emanzini olwandle kuye kwavela njengobuchwepheshe obuvelele ukuhlangabezana nesidingo esikhulayo semithombo yamanzi ahlanzekile. Ukuphumelela kokukhipha usawoti emanzini olwandle kuncike kakhulu ekusebenzeni kahle kanye nokusebenza kolwelwesi olusetshenziswa kule nqubo. Ubuchwepheshe obubili obuyinhloko be-membrane osebuthole ukuduma ulwelwesi lokukhipha usawoti emanzini olwandle kanye nolwelwesi lwe-osmosis oluhlehlayo.

Ulwelwesi lokukhipha usawoti emanzini olwandle kanye nolwelwesi lwe-osmosis oluhlehlayo zombili zisetshenziswa ezitshalweni zokukhipha usawoti emanzini ukuze kuhlukaniswe usawoti nokunye ukungcola emanzini olwandle. Nokho, ziyehluka ngesakhiwo, ukwakheka, nokusebenza. Ukuqonda lo mehluko kubalulekile ekukhetheni ubuchwepheshe be-membrane obufanele bezinhlelo zokusebenza ezithile.

I-Seawater Desalination Membrane:

Ulwelwesi lokukhipha usawoti emanzini olwandle luklanyelwe ngqo izimo ezinzima kanye namazinga aphezulu kasawoti atholakala ezitshalweni zokukhipha usawoti emanzini. Lezi zindwangu zenziwe ngezinto ezihlukahlukene, kuhlanganise ne-cellulose acetate, i-polyamide, ne-polysulfone. Zinongqimba oluqinile olusebenzayo uma kuqhathaniswa nolwelwesi lwe-osmosis oluhlehlayo, oluzivumela ukuthi zimelane nezingcindezi ezinzima ezidingekayo ekukhishweni kukasawoti emanzini.

Enye yezinzuzo ezibalulekile zolwelwesi lokususa usawoti emanzini olwandle ikhono lazo lokumelana nokungcoliswa. Ukungcola kwenzeka lapho i-particle iqoqa phezu kolwelwesi, kunciphisa ukusebenza kahle kwayo. Ukwakheka okuyingqayizivele kolwelwesi lokukhipha usawoti emanzini olwandle kuvimbela ukungcoliswa, kuqinisekisa ukusebenza okungaguquguquki nokuthembekile esikhathini eside.

I-Reverse Osmosis Membrane:

I-Reverse Osmosis membranes isetshenziswa kabanzi ezinhlelweni ezahlukahlukene, kufaka phakathi ukukhipha usawoti emanzini, ukuhlanza amanzi angcolile, nezinqubo zokuhlanza. Lawa ma-membrane ngokuvamile enziwa ngezinto eziyinhlanganisela yefilimu elincanyana, elihlanganisa ungqimba oluncane lwe-polymer olubekwe ezintweni ezisekelayo. Ungqimba oluncane olusebenzayo lunika amandla amazinga aphezulu okugeleza kwamanzi ngenkathi kugcinwa amandla amahle kakhulu okulahla usawoti.

Uma kuqhathaniswa nolwelwesi lokukhipha usawoti emanzini olwandle, ulwelwesi lwe-osmosis oluhlehlayo lusengozini yokonakala ngenxa yongqimba lwazo olusebenzayo oluzacile nezimbotshana ezincane. Kodwa-ke, inqubekelaphambili kubuchwepheshe be-membrane iholele ekwakhiweni kwezingubo zokulwa nokungcolisa kanye nezinqubo zokuhlanza ezithuthukisiwe, okunciphise izinkinga ezihlobene nokungcoliswa.

Ukuqhathaniswa kokusebenza:

Lapho kucutshungulwa ukuchithwa kwamanzi olwandle usawoti noma ubuchwepheshe bolwelwesi lwe-osmosis, kunezici ezimbalwa ezisebenzayo. Ukukhetha kuncike kakhulu ezidingweni ezithile zohlelo lokusebenza.

Ama-membranes okukhipha usawoti emanzini olwandle ahamba phambili ezindaweni ezinosawoti omningi futhi amelana nokungcoliswa. Banikeza amazinga amahle kakhulu okulahla usawoti, okuqinisekisa ukukhiqizwa kwamanzi ahlanzekile anosawoti omncane. Lokhu kwenza ulwelwesi lokukhipha usawoti emanzini olwandle lube lula ezindaweni ezisogwini ezibhekene nokushoda kwamanzi olwandle, lapho amanzi olwandle engumthombo wamanzi oyinhloko.
