I-Reverse Osmosis membranes (i-RO membranes) idlala indima ebalulekileimishini yokwelapha amanzi, esebenza njengengxenye eyinhloko yobuchwepheshe besimanje bokuhlanza amanzi. Lezi zinto ezikhethekile ze-membrane zisusa ngempumelelo usawoti oncibilikisiwe, ama-colloid, ama-microorganisms, izinto eziphilayo, nokunye ukungcola emanzini, ngaleyo ndlela kufinyelele ukuhlanzwa kwamanzi.
Ulwelwesi lwe-osmosis oluhlehlayo luwulwelwesi lokwenziwa lwe-semi-permeable olugqugquzelwe ulwelwesi lwebhayoloji olukwazi ukungena kancane. Zibonisa ukuvuthwa okukhethiwe, okuvumela kuphela ama-molecule amanzi kanye nezingxenye ezithile ukuthi zidlule ngaphansi kwengcindezi ephakeme kunokucindezela kwe-osmotic yesisombululo, kuyilapho kugcinwe ezinye izinto endaweni yolwelwesi. Ngobukhulu obuncane bembotshana (imvamisa engu-0.5-10nm), izimbotshana ze-RO zisusa kahle ukungcola emanzini.
Indima ye-reverse osmosis (RO) ulwelwesi ezinhlelweni zokwelashwa kwamanzi ibonakala ngokuyinhloko kulezi zici ezilandelayo:
1.Ukuhlanzwa kwamanzi
Ulwelwesi lwe-RO lususa kahle usawoti omningi oncibilikisiwe, ama-colloid, ama-microorganisms, nezinto eziphilayo emanzini, ukuqinisekisa ukuthi amanzi ahlanzekile ahlangabezana nezindinganiso zekhwalithi ephezulu. Leli khono lokuhlanza lisungula ulwelwesi lwe-RO njengobuchwepheshe obubalulekile ekukhiqizweni kwamanzi ahlanzekile, ukuhlanzwa kwamanzi okuphuza, kanye nokwelashwa kwamanzi angcolile ezimbonini.
2.Ukusebenza Kwamandla kanye nokusebenza Okuphezulu
Uma kuqhathaniswa nezindlela zendabuko zokuhlanza amanzi, amasistimu e-RO asebenza ngengcindezi ephansi, enciphisa kakhulu ukusetshenziswa kwamandla. Ukwengeza, ukusebenza kahle kwawo kokuhlunga okukhethekile kuvumela ukucutshungulwa ngokushesha kwamavolumu amakhulu amanzi, okuwenza alungele ukusetshenziswa kwenani elikhulu.
3.Ukusebenza Okulungele Umsebenzisi
Amasistimu okwelapha amanzi e-ROyakhelwe ukwenza kube lula ekusebenzeni, ekunakekeleni nasekuhlanzeni. Abasebenzisi bangalungisa kalula amapharamitha okusebenza (isb, ingcindezi, izinga lokugeleza) ukuze kuhlangatshezwane nezidingo ezihlukene zekhwalithi yamanzi.
4.Ukusebenziseka Okubanzi
Ama-membrane e-RO aguquguquka futhi avumelana nezimo ezihlukahlukene zokwelashwa kwamanzi, okuhlanganisa ukukhishwa kwamanzi olwandle usawoti, ukukhipha usawoti emanzini anosawoti, ukuhlanzwa kwamanzi okuphuza, nokugaywa kabusha kwamanzi angcolile ezimbonini. Lokhu kuguquguquka kuqinisekisa ukusetshenziswa kwabo okubanzi emikhakheni eminingi.
Ngokuhlanganisa lezi zinzuzo, ulwelwesi lwe-RO seluyinto ebaluleke kakhulu ekwelashweni kwamanzi kwesimanje, kubhekwana nezinselele zombili zokusebenza kahle nokusimama.
Kodwa-ke, ukusetshenziswa kolwelwesi lwe-reverse osmosis (RO) ezinhlelweni zokwelashwa kwamanzi kubhekana nezinselelo ezimbalwa. Isibonelo, izinhlelo ze-RO zidinga amazinga athile okucindezela kwamanzi—ukucindezela okunganele kunganciphisa kakhulu ukusebenza kahle kokwelashwa. Ukwengeza, ubude besikhathi sokuphila nokusebenza kolwelwesi lwe-RO kuthonywa izici ezifana nekhwalithi yamanzi, izimo zokusebenza (isb., i-pH, izinga lokushisa), kanye nokungcoliswa kokungcola.
Ukuze kubhekwane nalezi zinselelo, abacwaningi bazinikele ekwakheni izinto ezintsha namamojula we-membrane ye-RO ukuthuthukisa ukuqina kwe-membrane, ukusebenza kahle kokuhlunga, kanye nokumelana nokungcoliswa. Ngasikhathi sinye, kwenziwa imizamo yokuthuthukisa imingcele yokusebenza (isb, ingcindezi, izinga lokugeleza) kanye nomklamo wesistimu, okuhloswe ngayo ukunciphisa ukusetshenziswa kwamandla nokwelula impilo yesevisi yezisetshenziswa.
Uma sibheka phambili, intuthuko kwezobuchwepheshe kanye nokuqwashisa okukhulayo kwezemvelo kuzoqhuba ukusetshenziswa okubanzi kwe-RO membranes ekwelashweni kwamanzi. Izinto ezisetshenziswayo ezintsha kanye nemiklamo ye-modular izoqhubeka nokuvela, inikeze izixazululo ezisebenza kahle nezivumelana nemvelo embonini. Ngaphezu kwalokho, ukuhlanganiswa kobuchwepheshe obukhaliphile obufana ne-inthanethi Yezinto (IoT) kanye nedatha enkulu kuzonika amandla ukuphatha okuhlakaniphile, okuzenzakalelayo kwezinhlelo ze-RO, ukuthuthukisa ukusebenza kahle kokwelashwa kwamanzi, ikhwalithi, namazinga okuthola kabusha izinsiza.
Ekugcineni, ama-membrane e-osmosis ahlala ebaluleke kakhuluimishini yokwelapha amanzi, esebenza njengobuchwepheshe besisekelo sokuthola amanzi ahlanzekile. Ngokuthuthuka okuqhubekayo kokusetshenziswa kwe-membrane kanye nokwenza kahle kwesistimu, ubuchwepheshe be-RO bulungele ukudlala indima enkulu nakakhulu esikhathini esizayo, bunikele ekuhlanzeni, imithombo yamanzi ephephile emiphakathini yomhlaba wonke.
