Sebenzisa Amanzi Amsulwa Kakhulu Kwezisetshenziswa Ze-Dialysis ukuze Uthuthukise Ukuphepha kanye Nempumelelo Kokwelashwa Kwezinso
Isikhathi eside,izinhlelo zokuhlanza amanziokweukwelashwa kwe-hemodialysiskuthathwe njengemikhiqizo ehambisanayoamadivaysi e-dialysis.Nokho, ngesikhathi sokukhulelwaukwelashwa kwe-dialysisinqubo, i-99.3% ye-dialysate yakhiwe ngamanzi, asetshenziselwa ukuxubha ukugxila, ukuhlanza i-dialyzer, nemithi yokuthutha.Isiguli ngasinye esenziwa i-dialysis sizochayeka ku-15,000 kuya ku-30,000 wamalitha amanzi ahlungiwe ngonyaka.Ama-microorganisms, amakhemikhali, nokunye ukungcola emanzini kungase kubangele izifo, ubuthi, nezinye izinkinga ezinkulu ezigulini zesifo sezinso ezithola ukwelashwa kwe-dialysis, okubangela izimpawu ezifana nesifo samanzi aqinile, i-dialysis fever, ubuthi be-chloramine, kanye ne-hemolysis.Ucwaningo olushicilelwe kuIjenali ye-American Society of Nephrologywabonisa ukuthi usebenzisa i-ultra-purereverse osmosis water purifier systemskunganciphisa kakhulu izinga lokutheleleka ezigulini zokwelashwa kwe-HD ngaphezu kwama-30%.Ngakho-ke, ukuhlanzeka kweamanzi hemodialysiskuthinta ngqo ukuphepha nokusebenza kahle kweukwelashwa kwezinso.
Ukuze uthole amanzi e-dialysis ekhwalithi ephezulu, reverse osmosis (RO) amanziamasistimu okuhlungazisetshenziswa kabanzi.I-Reverse osmosis iyinqubo ehlukanisa amanzi nesisombululo ngokusebenzisa ulwelwesi olukwazi ukungena kancane.Umsebenzi uwukusebenzisa ukucindezela okukhulu ukudlulisa amanzi ukusuka ohlangothini oluphezulu lokugxila ngokusebenzisa i-membrane ye-semi-permeable kuya ohlangothini oluphansi lokugxila, ukuhlanza amanzi nokukhipha ukungcola.Kule nqubo, i-membrane ekwazi ukungena kancane ivumela kuphela ama-molecule amanzi ukuba adlule, kuyilapho ivimbela ama-solutes nokungcola kwezinhlayiyana ezinkulu.Lobu buchwepheshe bungasusa ngempumelelo ama-microorganisms, izinto eziqinile ezincibilikisiwe, nezinto eziphilayo emanzini.

Izitshalo zamanzi e-RO ngokuvamile zihlanganisa ukwelashwa kwangaphambili, ukuhlanzwa kwe-osmosis membrane, kanye nokwelashwa kwangemuva.Esinyathelweni sokuqala, amanzi ayahlungwa ukuze kukhishwe ukungcola kwezinhlayiyana ezinkulu, athambe ukuze kukhishwe izinto eziqinile, futhi kufakwe isibulala-magciwane ukuze kubulawe amagciwane.Khona-ke amanzi angena ekuhlanjululeni ulwelwesi lwe-osmosis ukuze ahlukaniswe emanzini ahlanzekile futhi agxilise, asuse ama-ion, ama-microorganisms, ukushisa, njll. Esinyathelweni sokugcina, ukukhishwa kwe-ultraviolet noma ukwelashwa kwe-ozone kusetshenziselwa ukuqinisekisa ukuthi amanzi ahambisana ne-dialysis akhiqizwa.
Amazinga wamazwe ngamazwe we-RO amanzi, akhiwe yi-US.I-Association for the Advancement of Medical Instrumentation (AAMI), ibhekwa njengamazinga aphezulu kakhulu.I-AAMI isungule izindinganiso eziqinile zekhwalithi yamanzi e-dialysis, edinga ukuthi inani eliphelele lama-microorganisms emanzini kufanele libe ngaphansi kwe-100 CFU/ml, ukuqhutshwa kwe-conductivity kufanele kube ngaphansi kuka-0.1μS/cm, ingqikithi yezinto eziqinile ezincibilikisiwe kufanele ibe ngaphansi 200 mg/L, futhi amanzi anzima kufanele abe ngaphansi kuka-100 mg/L, okuqukethwe kwensimbi kufanele kube ngaphansi kuka-0.1 μg/L, njalonjalo.

Ukuze kukhiqizwe amanzi e-RO ahlanzekile kakhulu, ahlangabezana nezindinganiso zamazwe omhlaba, izinkampani eziholayo zisebenzisa ubuchwepheshe obuphambili be-reverse osmosis membrane kanye nobuchwepheshe besistimu ye-multiple pass RO ukuthuthukisa ikhwalithi yamanzi we-hemodialysis.Amasistimu okuhlanza amanzi e-ROngokuqapha okuzenzakalelayo kanye nezinhlelo ze-alamu zingakwazi ukubona ukungahambi kahle kwekhwalithi yamanzi ngokushesha, iqinisekise ukuphepha nokucindezela okuqhubekayo kokunikezwa kwamanzi e-RO.
Njengomkhiqizi wemishini yokuhlanza amanzi e-RO enobuchwepheshe obuphambili obunamalungelo obunikazi amaningi, u-Wesley usebenzisa ulwelwesi lwangempela lwe-Dow, oluqinisekisa izinga elihle lamanzi nokukhiqizwa kwamanzi okuzinzile, futhi usebenzisa uhlelo lwamanzi lwe-Triple Pass ukuze ahlanze amanzi e-RO aphindaphindeka kabusha-double-pass ukuze aphume. Amanzi e-RO ahlanzekile kakhulu.Ngesikhathi sokukhiqizwa kwamanzi acwenge kakhulu, isiqaphi esisele se-chlorine/ubulukhuni esiku-inthanethi kanye nomtshina ovuzayo womshini wethu uyasebenza.Lezi zicelo zenza i-uhlelo lwamanzi lwe-dialysisenokwethenjelwa futhi esebenza kahle kakhulu, esetshenziswa nasezifundeni ezinezinga eliphansi lamanzi njenge-Afrika, ethola ukunconywa okuphezulu futhi.Esinye isici sezikhungo okufanele kukhulunywe ngazo ukuthi uhlobo lweumshini wamanzi we-RO ophathwayoiyatholakala.

Njengomkhiqizi womshini wekhwalithi ephezulu we-hemodialysis kanye nomphakeli wezixazululo ze-dialysis jikelele, u-Wesley uzibophezele ekuhlinzekeni ngemishini yezokwelapha engcono yeziguli ezinesifo sezinso nezikhungo zezokwelapha emhlabeni jikelele.
