Ukuqonda Ukuchithwa Kwamanzi Olwandle——I-Sea Water Reverse Osmosis Membrane

Njengamanje, ukukhishwa kukasawoti emanzini olwandle ikakhulukazi kusetshenziswa izindlela ezimbili zobuchwepheshe, okungukuthi, inqubo yokukhipha usawoti emanzini kulwelwesi olusekelwe reverse osmosis (RO) kanye nenqubo ye-thermal desalination esekelwe I-Multistage Flashing System (MSF) futhi I-Multiple Effect Distillation (MED):

1. Reverse osmosis (RO): Ukusetshenziswa kwe-reverse osmosis membrane, ngaphansi kwesenzo sokucindezela okukhulu, ngomphumela wokuhlola we-membrane aperture, usawoti kanye nokungcola emanzini olwandle kuyahlukaniswa ukuze kutholakale amanzi ahlanzekile.

2. Ukuhwamuka kwe-flash yezigaba eziningi: amanzi olwandle akhanya ngaphansi kwengcindezi ehlukene, futhi umhwamuko wamanzi namanzi awuketshezi ahlukaniswa ngokulawula ukuguqulwa kokucindezela ukuze kufezwe injongo yokukhipha usawoti.

3. Ukuhwamuka kwemiphumela eminingi: Ukusetshenziswa kwe-multi-stage evaporator, amanzi olwandle ashisa kancane kancane ukuhwamuka, isigaba ngasinye se-evaporator sisebenzisa isitimu esigabeni sangaphambilini se-evaporator ukuze sishise, ngaleyo ndlela konga amandla.

Ubuchwepheshe be-Reverse Osmosis (RO) busetshenziswa kakhulu ezitshalweni zokukhipha usawoti emanzini. I-Reverse Osmosis membrane iwubuchwepheshe obukhethekile bokuhlunga ulwelwesi, ngokusebenzisa ukucindezela okukhulu emanzini olwandle ngokuphoqa ulwelwesi, ukuze kuhlukanise usawoti, ama-microorganisms, izinto eziphilayo nokunye ukungcola, ukuthola amanzi ahlanzekile.

Izizathu zokuthi kungani ubuchwepheshe be-reverse osmosis busetshenziswa kabanzi ezitshalweni zokususa usawoti emanzini zifaka:

1. Ukusebenza kahle: I-Reverse Osmosis membrane inosawoti omningi kanye nokugeleza okuphezulu, okungasusa ngempumelelo usawoti kanye nokungcola emanzini olwandle futhi ithole amanzi ahlanzekile ekhwalithi ephezulu.

2. Ukonga amandla: Uma kuqhathaniswa nezindlela zendabuko zokukhipha usawoti emanzini ezifana ne-pyrolysis distillation, ubuchwepheshe be-osmosis obuhlanekezela budinga ukusetshenziswa kwamandla okuphansi. Enkambweni yokuhlukaniswa kwe-membrane, ingcindezi ethile kuphela ingasetshenziswa ukuze kuzuzwe ukuhlukaniswa kukasawoti, ngaphandle kwesidingo sokushisa okuphezulu nezimo ezicindezelayo, ngaleyo ndlela kugcinwe amandla.

3. Ukusimama: Ubuchwepheshe be-Reverse osmosis bufanele amaphrojekthi okukhipha usawoti emanzini abo bonke osayizi, kusukela ezitshalweni ezincane zokukhipha usawoti emanzini kuya ezitshalweni ezinkulu zokukhipha usawoti emanzini, ukuze kuzuzwe ukutholakala kwamanzi okusimeme. Ngesikhathi esifanayo, ulwelwesi lwe-osmosis oluhlehlayo lungahlanganiswa futhi lulungiswe ukuze luvumelane nekhwalithi yamanzi ehlukene kanye nezidingo zokwelashwa.

4. Umnotho: Nakuba ukutshalwa kwezimali kokuqala kobuchwepheshe be- reverse osmosis buphezulu, izindleko zakhona zehliswa kancane kancane ngokuthuthukiswa kobuchwepheshe kanye nokuthuthukiswa komphumela wesikali. Ngesikhathi esifanayo, ngenxa yokusebenza kahle okuphezulu kanye nezici zokusetshenziswa kwamandla okuphansi kobuchwepheshe be-osmosis ehlehlayo, izindleko zokusebenza nezokulungisa zingancishiswa futhi izinzuzo zezomnotho zingathuthukiswa.

Ubuchwepheshe bokukhipha usawoti emanzini olwandle bubaluleke kakhulu ekuxazululeni inkinga yokushoda kwamanzi kanye nokuhlangabezana nesidingo samanzi somuntu, futhi busetshenziswa kakhulu ezitshalweni zokukhipha usawoti emanzini, emikhunjini ehamba olwandle, ucwaningo lwesayensi yasolwandle kanye neminye imikhakha. Kodwa-ke, ubuchwepheshe bokukhipha usawoti emanzini buphinde bubhekane nezinselele ezifana nokusetshenziswa kwamandla, ukungcoliswa kwe-membrane kanye nokwelashwa kwamanzi angcolile, okudinga ukusungulwa okusha nokuthuthukiswa kwezobuchwepheshe okuqhubekayo.

Ulwelwesi lwe-seawater desalination luwuhlobo lwezinto ezisetshenziswa kulwelwesi olusetshenziswa kubuchwepheshe bokuhlukanisa ulwelwesi lwenqubo yokukhipha usawoti emanzini olwandle. Ama-membrane okukhipha usawoti emanzini asetshenziswa kakhulu ezinhlelweni zolwelwesi lwe-reverse osmosis (RO).

I-membrane ye-seawater desalination ngokuvamile yenziwa ngezinto ze-polymer ezifana ne-polyether ester (PE) noma i-polyether ether ketone (PEEK), enezici zokuvimbela usawoti ophezulu, ukugeleza okuphezulu nokumelana nokugqwala. Ukwakheka kolwelwesi kuvame ukuba ulwelwesi oluncane olunezimbotshana, oluhlukanisa usawoti nokungcola ngama-micropores kulwelwesi. Usayizi wembotshana wolwelwesi olukhishwa usawoti usawoti ngokuvamile uphakathi kuka-0.1-0.0001 micron, ongavimbela ngempumelelo ukudlula kukasawoti nezinye izinto ezincibilikayo, ukuze amanzi ahlanzekile akwazi ukudlula futhi afeze injongo yokukhipha usawoti emanzini olwandle.

Ulwelwesi lwe-Desalination ludlala indima ebalulekile kubunjiniyela bokukhipha usawoti emanzini. Inezinzuzo zokusebenza kahle okuphezulu, ukonga amandla kanye nokuvikelwa kwemvelo, okungaxazulula inkinga yokuntuleka kwamanzi futhi kunikeze umthombo othembekile wokuphakelwa kwamanzi. Njengamanje, ubuchwepheshe be-membrane ye-desalination sebungenye yezindlela ezisetshenziswa kakhulu zokukhipha usawoti emanzini emhlabeni.

Ulwelwesi lokukhipha usawoti emanzini lunezinzuzo ezilandelayo kunezinye izindlela zokususa usawoti emanzini:

1. Ukusebenza kahle: I-seawater desalination membrane ine-impedance ephezulu kasawoti, ukugeleza okuphezulu kanye nekhono lokuhlukanisa eliphumelelayo, elingasusa ngempumelelo usawoti kanye nokungcola emanzini olwandle futhi lithole amanzi ahlanzekile ekhwalithi ephezulu.

2. Ukonga amandla: Uma kuqhathaniswa nezindlela zendabuko zokususa usawoti emanzini njenge-pyrolysis distillation, ulwelwesi lokukhipha usawoti emanzini ludinga ukusetshenziswa kwamandla okuphansi. Enkambweni yokuhlukaniswa kwe-membrane, ingcindezi ethile kuphela ingasetshenziswa ukuze kuzuzwe ukuhlukaniswa kukasawoti, ngaphandle kwesidingo sokushisa okuphezulu nezimo ezicindezelayo, ngaleyo ndlela kugcinwe amandla.

3. Ukuvikelwa kwemvelo: Uma kuqhathaniswa nezinye izindlela, ulwelwesi lwe-desalination aludingi ukusebenzisa izinto zamakhemikhali noma izithasiselo ukuze kugwenywe ukungcoliswa kwemvelo. Ngesikhathi esifanayo, akukho manzi angcolile akhiqizwa ngesikhathi senqubo yokuhlukanisa ulwelwesi, okunciphisa ukuchithwa kwemithombo yamanzi.

4. Ukusimama: ubuchwepheshe be-membrane ye-desalination bungashintshwa ukuze buhambisane nezidingo zohlelo lokusebenza ngezindlela ezahlukene zokuhlukanisa ulwelwesi olufana ne-osmosis ehlehlayo kanye ne-nanofiltration. Lokhu kuvumelana nezimo kwenza ubuchwepheshe be-membrane bufanele bonke osayizi bemiklamo yokukhipha usawoti emanzini, kusukela kumayunithi amancane okukhipha usawoti emanzini kuya ezitshalweni ezinkulu zokukhipha usawoti emanzini, okuvumela ukutholakala kwamanzi okuqhubekayo.

5. Umnotho: Nakuba ukutshalwa kwezimali kokuqala kolwelwesi lokukhipha usawoti emanzini olwandle kuphezulu, izindleko zakhona zincishiswa kancane kancane ngokuthuthukiswa kobuchwepheshe kanye nokuthuthukiswa komphumela wesikali. Ngesikhathi esifanayo, ngenxa yokusebenza kahle okuphezulu kanye nezici zokusetshenziswa kwamandla okuphansi kwe-membrane yokukhipha usawoti emanzini olwandle, izindleko zokusebenza nezokugcina zingancishiswa futhi izinzuzo zezomnotho zingathuthukiswa.

Impilo yesevisi ye-membrane ye-desalination incike ezintweni ezihlukahlukene, kufaka phakathi ikhwalithi ye-membrane material, izimo zokusebenzisa ulwelwesi, ukusebenza nokugcinwa. Ngokuvamile, impilo yokuklama yolwelwesi lokukhipha usawoti emanzini ngokuvamile iphakathi kweminyaka emi-5 neyi-10.

Okulandelayo ezinye zezinto ezibalulekile ezithinta impilo yesevisi ye-desalination membranes:

1. Ikhwalithi yezinto ezibonakalayo ze-Membrane: Izinga nokuzinza kwe-membrane impahla kunomthelela obalulekile empilweni yesevisi ye-membrane. Izinto ezisezingeni eliphakeme ze-membrane zinokumelana nosawoti okuphezulu nokumelana nokugqwala, futhi zingagcina ukusebenza kokuhlukana okuzinzile ekusetshenzisweni kwesikhathi eside.

2. Izimo zokusebenza: Izimo zokusebenza nazo zinomthelela omkhulu empilweni yesevisi ye-membrane. Kubandakanya izinga lamanzi, izinga lokushisa, ingcindezi nezinye izici. Izinga lokushisa elidlulele, ingcindezi, noma amakhemikhali ekhwalithi yamanzi angabangela ulwelwesi ukuthi luguge, luqhekeke, noma luvale, ngaleyo ndlela kufinyeze impilo yesevisi yolwelwesi.

3. Isondlo: Ukuhlanza nokugcinwa kwe-membrane njalo kubalulekile ukuze kunwetshwe impilo yesevisi ye-membrane. Ukuhlanza njalo kungasusa ukungcola nosawoti ebusweni befilimu, kugcinwe ukugeleza nokusebenza kwefilimu. Ngesikhathi esifanayo, ukugcinwa okuvamile kungase futhi kubone futhi kubhekane nokulimala noma ukwehluleka kwe-membrane ngesikhathi ukuze kugwenywe ukulimala okuqhubekayo.
