Izinto eziningi ezinhle kakhulu
Sekungamakhulu eminyaka abalimi besebenzisa umquba wabo njengomanyolo. Lo mquba ucebile ngezakhamzimba namanzi futhi usakazeka emasimini ukusiza izitshalo zikhule. Kodwa-ke, ukufuywa kwezilwane okukhulu okubusa ezolimo zanamuhla namuhla kukhiqiza umquba omningi kakhulu kunalowo owawuvame ukuwukhiqiza endaweni efanayo.

“Nakuba umquba uyisivundisi esihle, ukuwusakaza kungabangela ukugeleza kwamanzi futhi kungcolise imithombo yamanzi ayigugu,” kusho uThurston. “Ubuchwepheshe be-LWR bungabuyisa futhi buhlanze amanzi, futhi buqoqe izakhamzimba ezivela endle.”

Uthe lolu hlobo lokucubungula luphinde lunciphise inani lokucubungula lonke, “okunikeza enye indlela engabizi kakhulu futhi enobungani nemvelo yabanikazi bezilwane.”

UThurston uchaze ukuthi le nqubo ihilela ukwelashwa kwamanzi ngomshini nangamakhemikhali ukuze kuhlukaniswe izakhamzimba kanye namagciwane endle.

“Igxile ekuhlukaniseni nasekuqongeleleni izakhamzimba eziqinile nezibalulekile njenge-phosphorus, i-potassium, i-ammonia kanye ne-nitrogen,” kusho yena.

Isinyathelo ngasinye senqubo sibamba izakhamzimba ezahlukene, bese kuthi, “isigaba sokugcina senqubo sisebenzisa uhlelo lokuhlunga ulwelwesi ukuze sithole amanzi ahlanzekile.”

Ngesikhathi esifanayo, “akukho ukukhishwa kwamanzi, ngakho-ke zonke izingxenye zokungenisa amanzi kokuqala zisetshenziswa futhi futhi ziphinde zisetshenziswe, njengomkhiqizo obalulekile, osetshenziswa kabusha embonini yezilwane,” kusho uThurston.

Izinto eziwusizo ziyingxube yomanyolo wezilwane namanzi, okufakwa ohlelweni lwe-LWR ngepompo yesikulufu. Isihlukanisi kanye nesihenqo kususa izinto eziqinile oketshezini. Ngemva kokuba izinto eziqinile zihlukanisiwe, uketshezi luqoqwa ethangini lokudlulisa. Ipompo esetshenziselwa ukuhambisa uketshezi iye esigabeni sokususa izinto eziqinile ezincane ifana nepompo yokungena. Uketshezi bese luphonswa ethangini lokuphakelayo lesistimu yokuhlunga i-membrane.

Iphampu ye-centrifugal ishayela uketshezi nge-membrane futhi ihlukanise umfudlana wenqubo ibe izakhamzimba ezigxilile namanzi ahlanzekile. I-valve ye-throttle ekugcineni kokukhipha izakhamzimba kohlelo lokuhlunga i-membrane ilawula ukusebenza kwe-membrane.

Ama-valve ohlelweni
I-LWR isebenzisa izinhlobo ezimbili ze-amavalvukuma-valve ayo e-system-globe ukuze kufakwe izinhlelo zokuhlunga ulwelwesi olugobile kanyeamavalvu ebholaukuze umuntu ahlukaniswe yedwa.

UThurston uchaze ukuthi ama-valve amaningi ebhola angama-valve e-PVC, ahlukanisa izingxenye zesistimu ukuze zilungiswe futhi zisetshenziselwe. Amanye ama-valve amancane nawo asetshenziselwa ukuqoqa nokuhlaziya amasampula avela ekusakazweni kwenqubo. I-valve yokuvala ilungisa izinga lokugeleza kokukhipha kokuhlunga kwe-membrane ukuze izakhamzimba namanzi ahlanzekile kuhlukaniswe ngephesenti elinqunyiwe.

“Amavalvu akulezi zinhlelo kudingeka akwazi ukumelana nezingxenye ezisendle,” kusho uThurston. “Lokhu kungahluka kuye ngendawo kanye nemfuyo, kodwa wonke amavalvu ethu enziwe nge-PVC noma insimbi engagqwali. Izihlalo zamavalvu zonke ziyi-EPDM noma irabha ye-nitrile,” enezela.

Iningi lamavalvu ohlelweni lonke lisebenza ngesandla. Nakuba kukhona amanye amavalvu ashintsha ngokuzenzakalelayo uhlelo lokuhlunga i-membrane kusuka ekusebenzeni okuvamile kuya enkambisweni yokuhlanza yangaphakathi, asebenza ngogesi. Ngemva kokuba inqubo yokuhlanza isiqediwe, lawa mavalvu azosuswa amandla futhi uhlelo lokuhlunga i-membrane luzoshintshwa lubuyele ekusebenzeni okuvamile.

Yonke inqubo ilawulwa yisilawuli se-logic esilungisekayo (i-PLC) kanye nesixhumi esibonakalayo somsebenzisi. Uhlelo lungafinyelelwa kude ukuze ubuke amapharamitha esistimu, wenze izinguquko zokusebenza, futhi uxazulule izinkinga.

“Inselele enkulu ebhekene nama-valve nama-actuator kule nqubo umoya oqothulayo,” kusho uThurston. “Uketshezi lwenqubo luqukethe i-ammonium, kanti okuqukethwe yi-ammonia ne-H2S emoyeni wesakhiwo nakho kuphansi kakhulu.”

Nakuba izifunda ezahlukene zezwe kanye nezinhlobo zezilwane zibhekene nezinselele ezahlukene, inqubo eyisisekelo iyonke iyafana endaweni ngayinye. Ngenxa yomehluko omncane phakathi kwezinhlelo zokucubungula izinhlobo ezahlukene zendle, “Ngaphambi kokwakha imishini, sizohlola indle yekhasimende ngalinye elabhorethri ukuze sithole uhlelo lokwelapha olungcono kakhulu. Lolu uhlelo oluqondene nomuntu siqu,” kusho uSeuss.

Isidingo esikhulayo
Ngokusho kwe-United Nations Water Resources Development Report, ezolimo njengamanje zibanga u-70% wokukhishwa kwamanzi ahlanzekile emhlabeni. Ngesikhathi esifanayo, ngo-2050, ukukhiqizwa kokudla emhlabeni kuzodingeka kwande ngo-70% ukuze kuhlangatshezwane nezidingo zabantu abalinganiselwa ku-9 billion. Uma kungekho ntuthuko kwezobuchwepheshe, akunakwenzeka.

Ukuhlangabezana nalesi sidingo. Izinto ezintsha kanye nentuthuko yobunjiniyela njengokuvuselelwa kwamanzi ezilwaneni kanye nokusungulwa kwama-valve okuthuthukisa ukuqinisekisa impumelelo yale mizamo kusho ukuthi iplanethi cishe izoba nemithombo yamanzi elinganiselwe futhi eyigugu, okuzosiza ukondla umhlaba.
