Zininzi kakhulu izinto ezilungileyo
Kangangeenkulungwane, abalimi bebesebenzisa umgquba wabo njengesichumisi. Lo mgquba utyebile kwizakhamzimba namanzi kwaye usasazwa emasimini ukunceda izityalo zikhule. Nangona kunjalo, ukufuywa kwezilwanyana ezinkulu okuphambili kwezolimo zanamhlanje kuvelisa umgquba omninzi kakhulu kunalowo wawusetyenziswa ekuveliseni umhlaba ofanayo.

“Nangona umgquba usisichumiso esilungileyo, ukuwusasaza kunokubangela ukugeleza kwamanzi kwaye kungcolise imithombo yamanzi exabisekileyo,” utshilo uThurston. “Itekhnoloji ye-LWR inokubuyisela amanzi kwaye iwacoce, kwaye igxininise izondlo ezivela kwilindle.”

Uthe olu hlobo lokucubungula lukwanciphisa umthamo wemveliso iyonke, “olubonelela ngenye indlela engabizi kakhulu neyinobuhlobo nokusingqongileyo yabasebenzi bemfuyo.”

UThurston uchaze ukuba le nkqubo ibandakanya unyango lwamanzi olusebenzisa umatshini nolweekhemikhali ukuze kwahlulwe izondlo kunye neentsholongwane kwindle.

“Igxile ekwahlulweni nasekuxinaniseni izondlo eziqinileyo nezixabisekileyo ezifana ne-phosphorus, i-potassium, i-ammonia kunye ne-nitrogen,” utshilo.

Inyathelo ngalinye lenkqubo libamba izondlo ezahlukeneyo, kwaye emva koko, "inqanaba lokugqibela lenkqubo lisebenzisa inkqubo yokucoca i-membrane ukuze kufumaneke amanzi acocekileyo."

Kwangaxeshanye, “akukho kukhutshwa kwamanzi, ngoko ke zonke iindawo zokungenisa amanzi okuqala ziphinda zisetyenziswe kwaye ziphinde zisetyenziswe, njengemveliso exabisekileyo, ziphinde zisetyenziswe kwishishini lemfuyo,” utshilo uThurston.

Izinto ezisetyenziswayo ngumxube womgquba wemfuyo kunye namanzi, ofakwa kwinkqubo ye-LWR ngepompo yesikrufu. Umhluzi kunye nesikrini zisusa izinto eziqinileyo kulwelo. Emva kokuba izinto eziqinileyo zahlulwe, ulwelo luqokelelwa kwitanki yokudlulisa. Ipompo esetyenziselwa ukuhambisa ulwelo ukuya kwinqanaba lokususa izinto eziqinileyo ezincinci iyafana nepompo yokungenisa. Ulwelo emva koko luphonswa kwitanki yokutya yenkqubo yokucoca i-membrane.

Ipompo ye-centrifugal iqhuba ulwelo nge-membrane kwaye yahlule umjelo wenkqubo ibe zizakhamzimba ezixineneyo kunye namanzi acocekileyo. Ivalvu ye-throttle ekupheleni kokukhupha izondlo kwinkqubo yokucoca i-membrane ilawula ukusebenza kwe-membrane.

Iivalvu kwinkqubo
I-LWR isebenzisa iintlobo ezimbini zeiivalvukwiivalvu zayo zenkqubo-iglobhu zeenkqubo zokucoca i-membrane kunyeiivalvu zebholaukuze umntu abe yedwa.

UThurston uchaze ukuba uninzi lweevalvu zebhola ziivalvu zePVC, ezihlukanisa izinto zenkqubo ukuze zigcinwe kwaye zisetyenzwe. Ezinye iivalvu ezincinci zikwasetyenziselwa ukuqokelela nokuhlalutya iisampulu ezivela kumjelo wenkqubo. Ivalvu yokuvala ilungisa izinga lokuphuma kokungcola kwe-membrane ukuze izondlo kunye namanzi acocekileyo zahlulwe ngepesenti emiselweyo.

“Iivalufa kwezi nkqubo kufuneka zikwazi ukumelana nezinto ezikwindle,” utshilo uThurston. “Oku kunokwahluka ngokuxhomekeke kwindawo kunye nemfuyo, kodwa zonke iivalufa zethu zenziwe ngePVC okanye ngentsimbi engagqwaliyo. Izihlalo zeevalufa zonke zezeEPDM okanye zerabha ye-nitrile,” wongezelela.

Uninzi lweevalvu kwinkqubo yonke zisebenza ngesandla. Nangona kukho ezinye iivalvu ezitshintsha ngokuzenzekelayo inkqubo yokucoca i-membrane ukusuka ekusebenzeni okuqhelekileyo ukuya kwinkqubo yokucoca kwindawo ethile, zisebenza ngombane. Emva kokuba inkqubo yokucoca igqityiwe, ezi valve ziya kuphelelwa ngamandla kwaye inkqubo yokucoca i-membrane iya kutshintshwa ibuyele ekusebenzeni okuqhelekileyo.

Yonke le nkqubo ilawulwa yi-programmable logic controller (PLC) kunye ne-operator interface. Inkqubo inokufikelelwa kude ukuze kujongwe iiparameter zenkqubo, kwenziwe utshintsho lokusebenza, kwaye kulungiswe iingxaki.

“Owona mceli mngeni mkhulu ojongene neevalvu kunye nee-actuators kule nkqubo ngumoya okonakalisayo,” utshilo uThurston. “Ulwelo lwenkqubo lune-ammonium, kwaye umxholo we-ammonia kunye ne-H2S kumoya wesakhiwo nawo uphantsi kakhulu.”

Nangona iindawo ezahlukeneyo zejografi kunye neentlobo zezilwanyana zijongene nemingeni eyahlukeneyo, inkqubo esisiseko iyonke iyafana kwindawo nganye. Ngenxa yokwahluka okuncinci phakathi kweenkqubo zokucubungula iintlobo ezahlukeneyo zendle, “Ngaphambi kokuba sakhe izixhobo, siza kuvavanya indle yomthengi ngamnye kwilebhu ukuze sifumane isicwangciso sonyango esifanelekileyo. Le yinkqubo eyenzelwe wena,” utshilo uSeuss.

Imfuno ekhulayo
NgokweNgxelo yoPhuhliso lweMithombo yamanzi yeZizwe eziManyeneyo, ezolimo okwangoku zithatha i-70% yamanzi acocekileyo afunyanwa ehlabathini. Kwangaxeshanye, ngo-2050, imveliso yokutya yehlabathi kuya kufuneka inyuke nge-70% ukuhlangabezana neemfuno zabantu abaqikelelwa kwi-9 yeebhiliyoni. Ukuba akukho nkqubela phambili kwezobuchwepheshe, akunakwenzeka.

Ukuhlangabezana nale mfuno. Izinto ezintsha kunye nophuhliso lobunjineli olufana nokurisayikilisha amanzi emfuyo kunye nophuhliso lweevalvu oluphuhlisiwe ukuqinisekisa impumelelo yale mizamo kuthetha ukuba iplanethi inokuba nemithombo yamanzi embalwa nexabisekileyo, eya kunceda ukondla ihlabathi.
