CUBA - Richard Velarde achangopedza maawa aine waya hanger muruoko, zvishoma nezvishoma achibvisa calcium deposits mumudziyo wake wemvura. Iyo yakajairika mvura yekudzosa kuMusha weCuba, uko Velarde ari kushanda kechipiri sameya.

"Kazhinji iwe unovhura pombi yako uye hapana chinobuda nekuti iyo buildup ine njodzi,” akadaro. "Mapaipi madiki ekupfapfaidza padivi pesingi - haugone kushandisa aya pano. Iwe wepamusoro une mafirita kana uchida kuchengetedza mahita ako emvura nemichina yekuwachisa. "

Ikozvino boka rekurima rine sarudzo inogoneka yedambudziko remvura - iro rinogona kubatsira maguta akasiyana nemaguta muNew Mexico kusimudzira mvura yavo yemhando yepamusoro..

Matsime uye matangi echikamu chemvura anotangira kumaSixties, zvinoreva guta revashoma pane 800 vanhu vari muSandoval County vari kuramba vachigadzira nekuchinja mavharuvhu nemapombi.

“Zvinoita sekunge ini chandinotarisira chete zvivakwa pano,” Velarde akadaro. “Kugadzirisa kunodhura zvikuru. Izvo zvinorema zvakakwana kuti maguta madiki abhadhare mubhadharo kazhinji, kuitira kuti zvisafambe zvishoma kune nyaya dzakaita sefungidziro yeinjiniya. "

Rimwe sangano parakasvika kuVelarde nechikumbiro chekuvaka nzvimbo uye kugadzirisa mvura inopombwa kubva patsime rebrackish riri pasi pemusha., akasvetukira pane imwe nzira.

Cuba yakasaina memorandamu yekunzwisisa muCan neKNeW Co. kugadzira chirimwa chinogona kupomba uye kubata nemvura kubva muaquifer, kupa kwete zvishoma pane 450,000 marita emvura pazuva kumusha.

Cuba inogara pamusoro peRio Puerco aquifer yakakura. Mainjiniya vanofungidzira kuti aquifer inosanganisira 2.6 mamiriyoni acre-tsoka - anenge 847 mabhiriyoni emarita - emvura ine brackish.

Zvisinei mvura ine munyu yakazadzwa necalcium, sodium uye sulfates. Maguta makuru akafanana neEl Paso neSan Diego anobata nemvura yepasi ine brackish ine desalination. Izvo hazvisi mukana wekumaruwa Cuba, nechikamu chayo chemvura chevanhu vana.

“Kubvisa mvura mumunyu kunodhura,” akadaro Aubrey Howard, mubatsiri uye CEO weKNeW Co. "Misha midiki haikwanise kudzosera zvirimwa zve osmosis uye zvinodikanwa zvinouya pamwe chete nazvo."

Kubvisa salination zvakare kunoburitsa hofori yakawanda yebrine.

Seimwe nzira, chirimwa ichi chichashandisa KNeW Co.'s ion change know-how yakapayona naJohn Bewsey, Injiniya wekuSouth Africa wemakemikari uye mutungamiriri wehunyanzvi paTrailblazer Applied sciences. KNeW inomirira "potassium nitrate ex wasste."

Matangi emvura akafukidzwa netumabead tudiki tunoita semagineti madiki, kuburitsa sodium, calcium kana magnesium mumvura ine brackish pasi pevhu kana mugodhi wetsvina.

Imwe seti yematangi inobvisa ese maion anochajiwa zvakanaka, izvo zvinozvibatanidza nemabeads.

Mabhero akachajiwa zvisina kunaka mune rimwe tangi anobvisa ma chlorides nema sulfates.

“Unosiiwa nemvura isina rusaruro uye isina chakanyungudika mairi,” Bewsey akadaro. “Dzidziso ratakawana pano nderekushandura maion aya asingadikanwi aya – ayo asati asvika pari zvino hapana aiziva zvekuita nawo – tinoashandura kuita fetereza.. Zvikurukuru, iyo inokosha ndeye potassium nitrate. Izvi zvinobhadhara kuomerwa kwese kwawabva waenda kunotora aya akanyungudika mumvura. ”

Fetereza yechirimwa inoreva kuti kambani inochinja mari kunyangwe isina kusimudzira mvura inobatwa.. Izvi zvinobvumira KNeW kupa mvura yakachena kuCuba, kusunungurwa kubva pamutengo.

“Tiri kuenda kunzvimbo yakafanira,” Howard akadaro. “Hatigadziri chero tsvina, semhedzisiro yekuti tiri kuishandura kuita chigadzirwa. Cuba ichave yega mvura, uye chero mari yavanowana kubva mairi ndeyavo.”

Cuba uye KNeW Co. vanogona kunyorera rubatsiro neU.S. Division of Agriculture neNew Mexico kubatsira mari kuchirimwa ichi. Iyo kambani ingada chaizvo simba rekuve mukugadzira nepamusoro pe 2021.

Mushure me $10 miriyoni yemvura yekurapa simiti inovakwa, Cuba yaizozvimiririra uye inoshanda simba. Kambani yaizobata "marara" pafetereza yakabatana.

Bewsey anoshandisa ruzivo rwake rwekugadzirisa acid mugodhi wemvura uye mvura yepasi ine brackish pane imwe nzvimbo yekutyaira muJohannesburg..

Chirimwa chakaongorora nzira yekushandura ion pamvura neyakafanana make-up nekuti Rio Puerco aquifer..

Nzira yacho “yakashanda zvinoshamisa,” Bewsey akadaro, uye inochenesa mvura zvachose zvekuti zvimwe zvicherwa zvinofanirwa kuwedzerwa zvakare kuti zvigutse zvinodiwa nemvura inopedza.

Iyo Cuba mishoni ndiyo yekutanga kuyedza neCalifornia-based firm kuwedzera mashandisirwo eBewsey kuziva-kuita muNorth America..

A New Mexico State College purofesa uye sainzi wemvura anoshanda semupangamazano wehunyanzvi kukambani, iyo yakatanga kuedza paRio Puerco aquifer makore akati wandei apfuura.

Basa reCuba rinovaka pamusoro pe 2011 tsvakiridzo yeaquifer yakapihwa neSandoval County.

Zvino, KNeW Co. iri kugumisa tsvakurudzo yezvinogoneka, 3-D modelling, uye nyika uye yemubatanidzwa inobvumidza kuCuba mvura kurapwa uye zvirimwa zvefetereza. Izvo zvinobatsira zvinogona kunge zvakavakwa pasuru yeU.S. Forest Service ivhu parumananzombe yeguta iyo ingangove yakapihwa kumusha.

Levi Casaus Jr., anoshanda neCuba water division, yakataura kuti chivakwa chitsva uye mvura yakachena inopa inogona kubatsira kuputsa mutengo wekugadzirisa-uye-kutsiva kutenderera kwemagetsi emagetsi nemidziyo yekugara..

“Iye zvino tave nemvura yakaoma kunyangwe mushure mekusefa,” Casaus akadaro. "Iwe uchaona calcium buildup mudhishi rako, geza musoro nemvura inodziya. Isu tinowanawo ma blockages mumamita edu uye nemasnicipal strains. Inotenga imwe mari hombe kudzoreredza uye kuchinjanisa izvi, uye zvinorevawo kuti tiri kurasikirwa nemvura. "

Cuba inoshandisa kutevedzana kwejecha, anthracite nematombo ekusefa simbi dzinorema uye zvicherwa zvakasiyana kubva mumvura. Iyo sefa midhiya inoshandurwa imwe neimwe matatu kuita 4 makore. Izvi 12 anotsiva mwedzi asvika pano netikiti remutengo we $92,000. Yakabhadharwa nemari yehurumende yekubhadhara mari.

Iyo Cuba system ine matangi maviri emvura, izvo zviri panzvimbo yakaparadzana kubva kune yekupomba uye yekurapa webhusaiti. Matsime ekare anoita zvishoma gore negore, saka ihondo yekuzadza matangi ega ega uye kuchengetedza mvura yakanaka.

“Zvino isu tine dzimwe nzvimbo dzenzvimbo kana tangi dhiri ichidonha, havangowani mvura chete,” Casaus akadaro. "Apo mvura inoyerera ikaenda neimwe nzira uye inowandisa, tinowana kuvuza uye kutsemuka kuzere mumatambudziko edu. Icho chiito chekuenzanisa. Tiri kufara nemakadhi ekutamba atakaitirwa.”

Imwe chirimwa chepakati chiri pedyo nemusha ndicho chaizogadzirisa huwandu hwemvura uhu uye matambudziko.

Chirimwa chiri kutaurwa chaizouya nematsime maviri ekupomba 2,700 ft pasi muaquifer, kupinda mukati memvura zhinji yakakura kupfuura iyo Cuba inogona panguva ino pombi 700 ft pasi mune imwe aquifer yakasiyana.

St. Johns, Arizona, yakasaina zvakare memorandamu yekunzwisisa neKNeW Co. kugadzira chirimwa chakafanana chekushandura brackish aquifer mvura kuita inopedza.

Meya Velarde akataura budiriro, pamwe chete nemabasa enguva dzose pafekitari yemvura uye mitero yakakomba kubva kufetereza, inogona kubatsira hupfumi hweCuba, nzvimbo iyo migwagwa yakavharwa nemakambani akavharwa kwenguva refu.

"Takagamuchira kuedza chinhu chimwe chakasiyana zvachose,” Velarde akadaro. “Tiri kurarama nezvatiinazvo iye zvino, zvisinei iye zvino tine mukana wekuti ive yakakwirira. Kupihwa mvura yakachena kungareva zvakati kuti kuboka iri. "
