Zinthu zabwino zambiri
Kwa zaka mazana ambiri, alimi akhala akugwiritsa ntchito manyowa awo ngati feteleza. Manyowa amenewa ali ndi michere yambiri komanso madzi ambiri ndipo amangofalikira m'minda kuti mbewu zikule. Komabe, ulimi waukulu wa ziweto womwe umayang'anira ulimi wamakono masiku ano umapanga manyowa ambiri kuposa momwe unkapangira pa nthaka yofanana.

“Ngakhale kuti manyowa ndi feteleza wabwino, kufalitsa kungayambitse madzi othamanga ndikuipitsa magwero amadzi amtengo wapatali,” anatero Thurston. “Ukadaulo wa LWR ukhoza kubwezeretsa ndi kuyeretsa madzi, ndikuyika michere m'madzi otayirira.”

Iye anati mtundu uwu wa kukonza umachepetsanso kuchuluka kwa kukonza, "kumapereka njira ina yotsika mtengo komanso yosawononga chilengedwe kwa ogwira ntchito za ziweto."

Thurston anafotokoza kuti njirayi imaphatikizapo kukonza madzi ndi makina kuti alekanitse zakudya ndi tizilombo toyambitsa matenda ndi ndowe.

"Imayang'ana kwambiri kulekanitsa ndi kusonkhanitsa michere yolimba komanso yamtengo wapatali monga phosphorous, potaziyamu, ammonia ndi nayitrogeni," adatero.

Gawo lililonse la ndondomekoyi limatenga zakudya zosiyanasiyana, kenako, "gawo lomaliza la ndondomekoyi limagwiritsa ntchito njira yosefera ya nembanemba kuti ipeze madzi oyera."

Nthawi yomweyo, "palibe mpweya woipa, kotero magawo onse a madzi oyamba omwe amatengedwa amagwiritsidwanso ntchito ndikubwezeretsedwanso, monga phindu lofunika, lomwe limagwiritsidwanso ntchito mumakampani a ziweto," adatero Thurston.

Zinthu zomwe zili ndi mphamvuzi ndi chisakanizo cha ndowe za ziweto ndi madzi, zomwe zimalowetsedwa mu dongosolo la LWR kudzera mu pampu yolumikizira. Cholekanitsa ndi chophimba zimachotsa zolimba kuchokera kumadzi. Zolimba zitalekanitsidwa, madziwo amasonkhanitsidwa mu thanki yosamutsira. Pampu yomwe imagwiritsidwa ntchito kusuntha madziwo kupita ku gawo lochotsa zolimba ndi yofanana ndi pampu yolowera. Madziwo amapopedwa mu thanki yodyetsera ya dongosolo losefera la nembanemba.

Pampu ya centrifugal imayendetsa madzi kudzera mu nembanemba ndikulekanitsa njira yogwirira ntchitoyo kukhala michere yochuluka ndi madzi oyera. Valavu yolumikizira kumapeto kwa njira yosefera ya nembanemba imayang'anira momwe nembanemba imagwirira ntchito.

Ma valve mu dongosolo
LWR imagwiritsa ntchito mitundu iwiri yamavavumu ma valve ake a system-globe kuti azitha kusefa ma membrane systems ndimavavu a mpirakudzipatula.

Thurston anafotokoza kuti ma valve ambiri a mpira ndi ma valve a PVC, omwe amalekanitsa zigawo za dongosolo kuti azisamalira ndi kutumikira. Ma valve ena ang'onoang'ono amagwiritsidwanso ntchito kusonkhanitsa ndi kusanthula zitsanzo kuchokera mumtsinje wa ndondomeko. Valavu yotseka imasintha kuchuluka kwa madzi otuluka mu kusefa kwa nembanemba kuti zakudya ndi madzi oyera zilekanitsidwe ndi kuchuluka komwe kunakonzedweratu.

"Ma valve omwe ali mu machitidwe awa ayenera kukhala okhoza kupirira zigawo zomwe zili mu ndowe," adatero Thurston. "Izi zitha kusiyana kutengera malo ndi ziweto, koma ma valve athu onse amapangidwa ndi PVC kapena chitsulo chosapanga dzimbiri. Mipando ya ma valve yonse ndi ya EPDM kapena rabara ya nitrile," adatero.

Ma valve ambiri mu dongosolo lonselo amayendetsedwa ndi manja. Ngakhale pali ma valve ena omwe amasintha okha njira yosefera ya nembanemba kuchokera ku ntchito yanthawi zonse kupita ku njira yoyeretsera yomwe ili mkati, amayendetsedwa ndi magetsi. Ntchito yoyeretsa ikatha, ma valve awa adzachotsedwa mphamvu ndipo njira yosefera ya nembanemba idzasinthidwanso kuti igwire ntchito yanthawi zonse.

Njira yonseyi imayang'aniridwa ndi pulogalamu yowongolera ma logic (PLC) ndi mawonekedwe a opareta. Dongosololi likhoza kupezeka patali kuti muwone magawo a dongosolo, kusintha magwiridwe antchito, ndikuwongolera mavuto.

"Vuto lalikulu lomwe ma valve ndi ma actuator akukumana nalo mu ndondomekoyi ndi mlengalenga wowononga," adatero Thurston. "Madzimadzi a process ali ndi ammonium, ndipo ammonia ndi H2S zomwe zili mu mlengalenga wa nyumbayo ndizochepa kwambiri."

Ngakhale madera osiyanasiyana ndi mitundu ya ziweto zimakumana ndi mavuto osiyanasiyana, njira yonse yoyambira ndi yofanana pa malo aliwonse. Chifukwa cha kusiyana kochepa pakati pa machitidwe ogwiritsira ntchito mitundu yosiyanasiyana ya ndowe, "Tisanapange zida, tidzayesa ndowe za kasitomala aliyense mu labotale kuti tidziwe njira yabwino kwambiri yothandizira. Iyi ndi njira yopangidwira munthu payekha," adatero Seuss.

Kufunika kwakukulu
Malinga ndi lipoti la United Nations Water Resources Development Report, ulimi pakadali pano umapanga 70% ya madzi abwino padziko lonse lapansi. Nthawi yomweyo, pofika chaka cha 2050, kupanga chakudya padziko lonse lapansi kuyenera kuwonjezeka ndi 70% kuti kukwaniritse zosowa za anthu pafupifupi 9 biliyoni. Ngati palibe kupita patsogolo kwaukadaulo, sizingatheke.

Kukwaniritsa zosowa izi. Zipangizo zatsopano ndi zatsopano monga kubwezeretsanso madzi a ziweto ndi zatsopano za ma valavu zomwe zapangidwa kuti zitsimikizire kuti ntchitoyi ikuyenda bwino zikutanthauza kuti dziko lapansi likhoza kukhala ndi madzi ochepa komanso amtengo wapatali, zomwe zingathandize kudyetsa dziko lapansi.
