Ziningi kakhulu izinto ezinhle
Sekungamakhulu eminyaka abalimi besebenzisa umquba wabo njengomanyolo. Lo mquba unothile ngemisoco namanzi futhi usakazwa nje emasimini ukuze usize izitshalo zikhule. Nokho, ukufuywa kwezilwane ngezinga elikhulu okubusa ezolimo zanamuhla namuhla kukhiqiza umquba omningi kakhulu kunangaphambili owawuwukhiqiza endaweni efanayo.

“Nakuba umquba uwumanyolo omuhle, ukuwusakaza kungabangela ukugeleza nokungcolisa imithombo yamanzi ayigugu,” kusho uThurston. “Ubuchwepheshe be-LWR bungabuyisa futhi buhlanze amanzi, futhi bugxilise imisoco endle.”

Uthe lolu hlobo lokucubungula luphinde lwehlise inani eliphelele lokucutshungulwa, "okuhlinzeka ngenye indlela engabizi kakhulu futhi ehambisana nemvelo kubasebenzi bemfuyo."

U-Thurston wachaza ukuthi le nqubo ihilela ukwelashwa kwamanzi ngomshini namakhemikhali ukuze kuhlukaniswe izakhi kanye namagciwane endle.

"Igxile ekuhlukaniseni nasekugxilweni kwezakhi eziqinile nezibalulekile ezifana ne-phosphorus, i-potassium, i-ammonia ne-nitrogen," esho.

Isinyathelo ngasinye senqubo sithatha imisoco ehlukahlukene, bese “isigaba sokugcina senqubo sisebenzisa isimiso sokuhlunga ulwelwesi ukuze sibuyise amanzi ahlanzekile.”

Ngesikhathi esifanayo, "ukukhishwa kwe-zero, ngakho-ke zonke izingxenye zokusetshenziswa kwamanzi okuqala ziphinde zisetshenziswe futhi zigaywe kabusha, njengomphumela obalulekile, ophinde usetshenziswe embonini yemfuyo," kusho u-Thurston.

Impahla enomthelela ingxube yobulongwe bemfuyo namanzi, afakwa ohlelweni lwe-LWR ngepompo yesikulufu. Isihlukanisi kanye nesikrini kukhipha okuqinile oketshezini. Ngemva kokuhlukaniswa kwezinto eziqinile, uketshezi luqoqwa ethangini lokudlulisa. Iphampu esetshenziselwa ukuhambisa uketshezi esigabeni sokususa izinto eziqinile iyafana nepompo yokungena. Uketshezi lube seluphonswa kuthangi lokuphakelayo lesistimu yokuhlunga ulwelwesi.

Iphampu ye-centrifugal ishayela uketshezi kulwelwesi futhi ihlukanise ukusakazwa kwenqubo kube izakhamzimba ezigxilile namanzi ahlanzekile. I-valve ye-throttle ekupheleni kokukhishwa kwezakhi zohlelo lokuhlunga i-membrane ilawula ukusebenza kwe-membrane.

Amavalvu ohlelweni
I-LWR isebenzisa izinhlobo ezimbili zeama-valvekuma-valve ayo e-system-globe for throttling membrane filtration systems kanyeama-valve ebholaukuze uzihlukanise.

U-Thurston wachaza ukuthi ama-valve amaningi ebhola ama-valve e-PVC, ahlukanisa izingxenye zesistimu ukuze zilungiswe futhi zisebenze. Amanye ama-valve amancane nawo asetshenziselwa ukuqoqa nokuhlaziya amasampula asuka emfudlaneni wenqubo. I-valve yokuvala ilungisa izinga lokugeleza kokukhishwa kwe-membrane filtration ukuze imisoco kanye namanzi ahlanzekile kuhlukaniswe ngephesenti elinqunywe kusengaphambili.

"Ama-valve akulezi zinhlelo adinga ukuthi akwazi ukumelana nezingxenye ezisendle," kusho uThurston. “Lokhu kungase kwehluke kuye ngendawo nemfuyo, kodwa wonke amavalvu ethu enziwe ngePVC noma ngensimbi engagqwali. Izihlalo zamavalvu zonke ziyi-EPDM noma irabha ye-nitrile,” wengeza.

Ama-valve amaningi kulo lonke uhlelo asebenza ngesandla. Nakuba kukhona ama-valve athile ashintsha ngokuzenzakalelayo uhlelo lokuhlunga ulwelwesi lusuke ekusebenzeni okuvamile luye kunqubo yokuhlanza endaweni, asebenza ngogesi. Ngemuva kokuthi inqubo yokuhlanza isiqediwe, lawa ma-valve azokhishwa amandla futhi uhlelo lokuhlunga ulwelwesi luzoshintshwa lubuyele ekusebenzeni okujwayelekile.

Yonke le nqubo ilawulwa isilawuli se-programmable logic (PLC) kanye nesixhumi esibonakalayo somsebenzisi. Isistimu ingafinyelelwa ukude ukuze ubuke amapharamitha wesistimu, wenze izinguquko zokusebenza, futhi uxazulule inkinga.

"Inselelo enkulu ebhekene nama-valve nama-actuator kule nqubo isimo esibi," kusho uThurston. "Uketshezi lwenqubo luqukethe i-ammonium, kanti i-ammonia ne-H2S okuqukethwe emkhathini wokwakha nakho kuphansi kakhulu."

Nakuba izifunda ezahlukene zendawo kanye nezinhlobo zemfuyo zibhekana nezinselele ezihlukene, inqubo eyisisekelo iyonke iyafana endaweni ngayinye. Ngenxa yomehluko ocashile phakathi kwamasistimu okucubungula izinhlobo ezahlukene zendle, “Ngaphambi kokwakha okokusebenza, sizohlola indle yekhasimende ngalinye elabhorethri ukuze sithole uhlelo lokwelapha olungcono kakhulu. Lolu wuhlelo lomuntu siqu,” kusho uSeuss He.

Isidingo esikhulayo
Ngokombiko we-United Nations Water Resources Development Report, ezolimo njengamanje zenza u-70% wokukha amanzi ahlanzekile emhlabeni. Ngaso leso sikhathi, ngo-2050, ukukhiqizwa kokudla emhlabeni wonke kuyodingeka kukhule ngamaphesenti angama-70 ukuze kuhlangatshezwane nezidingo zabantu abalinganiselwa ezigidini eziyisi-9. Uma kungekho ukuthuthuka kwezobuchwepheshe, akunakwenzeka

Hlangana nalesi sidingo. Izinto ezintsha kanye nokuphumelela kobunjiniyela okufana nokugaywa kabusha kwamanzi emfuyo kanye nokuqanjwa kwamavalvu okuthuthukisiwe ukuze kuqinisekiswe impumelelo yale mizamo kusho ukuthi iplanethi ingase ibe nemithombo yamanzi elinganiselwe neyigugu, ezosiza ukondla umhlaba.
