Zinthu zabwino zambiri
Kwa zaka mazana ambiri, alimi akhala akugwiritsa ntchito manyowa awo monga fetereza. Manyowawa ali ndi zakudya zambiri komanso madzi ndipo amangowaza m’minda kuti mbewu zikule. Komabe, kuweta kwa nyama zazikulu kumene kuli paulimi wamakono lerolino kumatulutsa manyowa ochuluka kuposa mmene amachitira poyamba pa nthaka yofanana.

"Ngakhale kuti manyowa ndi feteleza wabwino, kufalitsa kungayambitse madzi othamanga ndi kuipitsa magwero a madzi amtengo wapatali," adatero Thurston. "Tekinoloje ya LWR imatha kubweza ndikuyeretsa madzi, ndikuyikanso michere m'chimbudzi."

Ananenanso kuti kukonza kwamtunduwu kumachepetsanso kuchuluka kwazinthu zonse, "kumapereka njira yotsika mtengo komanso yosawononga chilengedwe kwa ogwira ntchito zoweta."

Thurston anafotokoza kuti njirayi imaphatikizapo mankhwala opangidwa ndi madzi ndi mankhwala kuti alekanitse zakudya ndi tizilombo toyambitsa matenda ku ndowe.

"Izo zimayang'ana pa kulekanitsa ndi kuchuluka kwa zakudya zolimba komanso zamtengo wapatali monga phosphorous, potaziyamu, ammonia ndi nayitrogeni," adatero.

Gawo lirilonse la ndondomekoyi limatenga zakudya zosiyanasiyana, ndiyeno, "gawo lomaliza la ndondomekoyi limagwiritsa ntchito sefa ya membrane kuti mutenge madzi abwino."

Panthawi imodzimodziyo, "kutulutsa kwa zero, kotero kuti mbali zonse za madzi oyambilira zimagwiritsidwanso ntchito ndikusinthidwanso, monga phindu lamtengo wapatali, zimagwiritsidwanso ntchito m'makampani a ziweto," adatero Thurston.

Zomwe zimakhudzidwa ndi chisakanizo cha manyowa a ziweto ndi madzi, omwe amalowetsedwa mu LWR system kudzera pa screw pump. Cholekanitsa ndi chophimba zimachotsa zolimba kuchokera kumadzimadzi. Zolimba zitasiyanitsidwa, madziwo amasonkhanitsidwa mu thanki yotengerapo. Pampu yomwe imagwiritsidwa ntchito kusuntha madzi kupita kumalo ochotsera zinthu zolimba ndi yofanana ndi mpope wolowera. Madziwo amaponyedwa mu tanki ya chakudya ya membrane kusefera dongosolo.

Pampu ya centrifugal imayendetsa madzi kudzera mu nembanemba ndikulekanitsa mtsinjewo kukhala zakudya zokhazikika komanso madzi oyera. The throttle valve kumapeto kwa michere yotulutsa michere ya membrane kusefera imawongolera magwiridwe antchito a nembanemba.

Ma valve mu dongosolo
LWR imagwiritsa ntchito mitundu iwiri yamavavumu ma valve ake a system-globe for throttling membrane filtration systems ndima valve a mpiraza kudzipatula.

Thurston adalongosola kuti ma valve ambiri a mpira ndi ma valve a PVC, omwe amalekanitsa zigawo za dongosolo kuti zisamalidwe ndi ntchito. Ma valve ena ang'onoang'ono amagwiritsidwanso ntchito kusonkhanitsa ndi kusanthula zitsanzo kuchokera mumtsinje wa ndondomeko. Valavu yotseka imasintha kuchuluka kwa kutulutsa kwa membrane kusefera kuti zakudya ndi madzi oyera zitha kulekanitsidwa ndi chiwerengero chodziwikiratu.

"Mavavu mu machitidwewa ayenera kukhala okhoza kupirira zigawo zikuluzikulu mu ndowe," adatero Thurston. "Izi zimatha kusiyana kutengera dera ndi ziweto, koma ma valve athu onse amapangidwa ndi PVC kapena chitsulo chosapanga dzimbiri. Mipando ya valve yonse ndi EPDM kapena mphira wa nitrile, "adaonjeza.

Ma valve ambiri mu dongosolo lonse amayendetsedwa pamanja. Ngakhale pali ma valve ena omwe amangosintha makina osefera a membrane kuchoka ku ntchito yanthawi zonse kupita ku in-situ kuyeretsa, amagwira ntchito ndi magetsi. Ntchito yoyeretsa ikatha, mavavuwa amachotsedwa mphamvu ndipo makina osefera a membrane amasinthidwa kuti agwire bwino ntchito.

Njira yonseyi imayendetsedwa ndi programmable logic controller (PLC) ndi mawonekedwe opangira. Dongosololi litha kupezeka patali kuti muwone magawo adongosolo, kusintha magwiridwe antchito, ndikuthetsa mavuto.

"Vuto lalikulu lomwe ma valve ndi ma actuators akukumana nawo pakuchita izi ndi mlengalenga wowononga," adatero Thurston. "Njira yamadzimadziyi imakhala ndi ammonium, ndipo ammonia ndi H2S zomwe zili mumlengalenga ndizochepa kwambiri."

Ngakhale madera osiyanasiyana komanso mitundu ya ziweto zimakumana ndi zovuta zosiyanasiyana, njira zonse zoyambira ndizofanana pagawo lililonse. Chifukwa cha kusiyana kobisika pakati pa makina opangira ndowe zamitundu yosiyanasiyana, “Tisanapange zidazi, tiziyesa ndowe za kasitomala aliyense mu labotale kuti tidziwe njira yabwino yochizira. Iyi ndi dongosolo lamunthu, "adatero Seuss He.

Kukula kufunikira
Malinga ndi lipoti la United Nations Water Resources Development Report, ulimi panopa ndi 70% ya madzi opanda mchere padziko lonse lapansi. Panthawi imodzimodziyo, pofika chaka cha 2050, chakudya cha padziko lonse chiyenera kuwonjezeka ndi 70% kuti chikwaniritse zosowa za anthu pafupifupi 9 biliyoni. Ngati palibe kupita patsogolo kwaukadaulo, sizingatheke

Gwirani izi. Zipangizo zatsopano ndi luso laumisiri monga kukonzanso madzi a ziweto ndi zatsopano za valve zomwe zapangidwa kuti zitsimikizire kuti zoyesayesazi zikuyenda bwino zikutanthauza kuti dziko lapansi likhoza kukhala ndi madzi ochepa komanso amtengo wapatali, omwe angathandize kudyetsa dziko lapansi.
