Sebenzisa Amanzi Ahlanzekile Kakhulu Emishinini Yokuhlanza Izinso Ukuze Uthuthukise Ukuphepha Nokusebenza Kahle Kokwelashwa Kwezinso
Isikhathi eside,izinhlelo zokuhlanza amanzingobaukwelashwa kwe-hemodialysiskubhekwe njengemikhiqizo ehambisanayoamadivayisi okuhlanza igaziNokho, ngesikhathiukwelashwa nge-dialysisInqubo, u-99.3% we-dialysate wakhiwe ngamanzi, asetshenziselwa ukuncibilikisa i-concentrate, ukuhlanza i-dialyzer, kanye nokuthutha imithi. Isiguli ngasinye esithola i-dialysate sizovezwa amalitha amanzi ahlungiwe angu-15,000 kuya ku-30,000 ngonyaka. Amagciwane, amakhemikhali, kanye nokunye ukungcola emanzini kungaholela ekuthelelekeni, ubuthi, kanye nezinye izinkinga ezinkulu ezigulini ezinesifo sezinso ezithola ukwelashwa nge-dialysate, okubangela izimpawu ezifana ne-hard water syndrome, umkhuhlane we-dialysate, ubuthi be-chloramine, kanye ne-hemolysis. Ucwaningo olushicilelwe ku-Ijenali ye-American Society of Nephrologykubonise ukuthi ukusebenzisa i-ultra-pureizinhlelo zokuhlanza amanzi ze-reverse osmosiskunganciphisa kakhulu izinga lokutheleleka kweziguli ezithola ukwelashwa nge-HD ngaphezu kuka-30%. Ngakho-ke, ubumsulwa beamanzi e-hemodialysiskuthinta ngqo ukuphepha kanye nokusebenza kahle kweukwelashwa kwezinso.
Ukuze uthole amanzi e-dialysis asezingeni eliphezulu, faka amanzi e-reverse osmosis (RO)izinhlelo zokuhlungazisetshenziswa kabanzi. I-reverse osmosis inqubo ehlukanisa amanzi nesixazululo nge-membrane engena kancane. Umsebenzi ukusebenzisa umfutho ophezulu ukudlulisa amanzi kusukela ohlangothini olune-concentration ephezulu ngokusebenzisa i-membrane engena kancane aye ohlangothini olune-concentration ephansi, ukuhlanza amanzi nokususa ukungcola. Kule nqubo, i-membrane engena kancane ivumela kuphela ama-molecule amanzi ukuthi adlule, kuyilapho ivimbela ukuncibilika kanye nokungcola okukhulu kwezinhlayiya. Lobu buchwepheshe bungasusa ngempumelelo ama-microorganisms, izinto eziqinile ezincibilikisiwe, kanye nezinto eziphilayo emanzini.

Izitshalo zamanzi ze-RO zivame ukufaka ukwelashwa kwangaphambi kwesikhathi, ukuhlanzwa kwe-reverse osmosis membrane, kanye nokwelashwa kwangemva kokwelashwa. Esinyathelweni sokuqala, amanzi ayahlungwa ukuze kususwe ukungcola okukhulu kwezinhlayiya, athambekele ukuze kususwe izinto eziqinile, futhi ahlanzwe amagciwane ukuze kubulawe amagciwane. Bese amanzi engena ekuhlanzweni kwe-reverse osmosis membrane ukuze ahlukaniswe abe ngamanzi ahlanzekile futhi agxile, kususwe ama-ion, ama-microorganisms, ukushisa, njll. Esinyathelweni sokugcina, kusetshenziswa ukubulala amagciwane nge-ultraviolet noma ukwelashwa nge-ozone ukuqinisekisa ukuthi kukhiqizwa amanzi e-dialysis ahambisana nezindinganiso.
Izindinganiso zamazwe ngamazwe zamanzi ze-RO, ezakhiwe yi-US. Association for the Advancement of Medical Instrumentation (AAMI), zibhekwa njengezindinganiso eziphakeme kakhulu. I-AAMI imise izindinganiso eziqinile zekhwalithi yamanzi e-dialysis, idinga ukuthi inani eliphelele lama-microorganism emanzini libe ngaphansi kuka-100 CFU/ml, ukuhanjiswa komoya kufanele kube ngaphansi kuka-0.1μS/cm, inani eliphelele lama-solids ancibilikisiwe kufanele libe ngaphansi kuka-200 mg/L, kanti amanzi asindayo kufanele abe ngaphansi kuka-100 mg/L, okuqukethwe kwensimbi kufanele kube ngaphansi kuka-0.1 μg/L, njalo njalo.

Ukuze kukhiqizwe amanzi e-RO ahlanzekile kakhulu, ahlangabezana nezindinganiso zesitifiketi samazwe ngamazwe, izinkampani ezihamba phambili zisebenzisa ubuchwepheshe obuthuthukisiwe be-reverse osmosis membrane kanye nobuchwepheshe besistimu ye-RO yokudlula okuningi ukuthuthukisa ikhwalithi yamanzi e-hemodialysis.Izinhlelo zokuhlanza amanzi ze-RONgezinhlelo zokuqapha okuzenzakalelayo kanye ne-alamu, ingabona ukukhubazeka kwekhwalithi yamanzi ngokushesha, iqinisekise ukuphepha kanye nokucindezela okuqhubekayo kokuhlinzekwa kwamanzi kwe-RO.
Njengomkhiqizi wemishini yokwelapha amanzi ye-RO enobuchwepheshe obuhlukahlukene obuthuthukisiwe obunelungelo lobunikazi, uWesley usebenzisa ama-membrane okuqala e-Dow, aqinisekisa ikhwalithi yamanzi enhle kanye nokukhiqizwa kwamanzi okuzinzile, futhi usebenzisa uhlelo lwamanzi lwe-Triple Pass ukuhlanza amanzi e-RO aphindaphindwayo kabili ukuze akhiphe amanzi e-RO amsulwa kakhulu. Ngesikhathi sokukhiqizwa kwamanzi amsulwa kakhulu, i-residual chlorine/hardness monitor kanye ne-leak detector yomshini wethu iyasebenza. Lezi zinhlelo zokusebenza zenza i-uhlelo lwamanzi oluhlanzayoithembeke kakhulu futhi isebenza kahle, isetshenziswa ngisho nasezindaweni ezinezinga eliphansi lamanzi njenge-Afrika, futhi ithola udumo olukhulu. Esinye isici sezikhungo okufanele sishiwo ukuthi uhlobo lwe-umshini wamanzi we-RO ophathwayoiyatholakala.

Njengomkhiqizi wemishini ye-hemodialysis esezingeni eliphezulu kanye nomhlinzeki wezixazululo ze-dialysis jikelele, uWesley uzibophezele ekuhlinzekeni ngemishini yezokwelapha engcono yeziguli ezinesifo sezinso kanye nezikhungo zezokwelapha emhlabeni jikelele.
