Shandisa Mvura Yakachena Zvakanyanya paMidziyo yeDialysis Kuti Uvandudze Kuchengetedzeka uye Kushanda Kwekurapwa kweItsvo
Kwenguva yakareba,masisitimu ekuchenesa mvurayekurapwa kwe hemodialysiszvinoonekwa sezvigadzirwa zvekuwedzera kunemichina yekuchenesa ropa (dialysis)Zvisinei, panguva yekurapwa kwe dialysisMuchiitiko ichi, 99.3% ye dialysate inoumbwa nemvura, iyo inoshandiswa kunyungudutsa concentrate, kuchenesa dialyzer, uye kutakura mishonga. Murwere wega wega ari ku dialysate achasangana nemarita 15,000 kusvika 30,000 emvura yakasefetwa pagore. Zvirwere, makemikari, nezvimwe zvinosvibisa mumvura zvinogona kutungamira kuhutachiona, chepfu, uye zvimwe zvinetso zvakakomba muvarwere vane chirwere cheitsvo vari kurapwa dialysis, zvichikonzera zviratidzo zvakaita se hard water syndrome, dialysis fever, chloramine poisoning, uye hemolysis. Chidzidzo chakaburitswa muChinyorwa cheAmerican Society of Nephrologyzvakaratidza kuti kushandisa ultra-puremasisitimu ekuchenesa mvura e reverse osmosiszvinogona kuderedza zvakanyanya huwandu hwehutachiona muvarwere vanorapwa neHD neanopfuura 30%. Saka, kuchena kwemvura ye hemodialysiszvinokanganisa zvakananga kuchengetedzeka uye kushanda kwekurapwa kweitsvo.
Kuti uwane mvura yekuchenesa yemhando yepamusoro, shandisa reverse osmosis (RO) watermasisitimu ekusefaZvinoshandiswa zvakanyanya. Reverse osmosis inzira inoparadzanisa mvura kubva kune imwe mvura kuburikidza nekamera inopindika zvishoma. Basa nderekushandisa simba rakawanda kutamisa mvura kubva kudivi rine huwandu hwakawanda kuburikidza nekamera inopindika zvishoma kuenda kudivi rine huwandu hwakaderera, kuchenesa mvura nekubvisa tsvina. Mukuita uku, kamera inopindika zvishoma inongobvumira mamorekuru emvura kupfuura nepakati, uku ichidzivirira kusvibiswa kwezvimedu netsvina huru. Iyi tekinoroji inogona kubvisa zvinobudirira tupukanana, zvinhu zvakanyungudutswa, uye zvinhu zvakasikwa mumvura.

Zvivako zvemvura zveRO zvinowanzo sanganisira kurapwa kwekutanga, kucheneswa kwemembrane ye reverse osmosis, uye kurapwa mushure mekurapwa. Padanho rekutanga, mvura inoseferwa kuti ibvise tsvina hombe, inonyoroveswa kuti ibvise zvinhu zvakaoma, uye inouraya mabhakitiriya. Zvadaro mvura inopinda mukucheneswa kwemembrane ye reverse osmosis kuti iparadzaniswe kuita mvura yakachena uye concentrate, kubvisa maion, tupukanana, kupisa, nezvimwewo. Padanho rekupedzisira, ultraviolet disinfection kana ozone treatment inoshandiswa kuona kuti mvura ye dialysis inoenderana nezvinodiwa nemutemo inogadzirwa.
Mitemo yeRO water international, yakagadzirwa neUS Association for the Advancement of Medical Instrumentation (AAMI), inoonekwa seyepamusoro-soro. AAMI yakaisa mitemo yakasimba yemhando yemvura yedialysis, ichida kuti huwandu hwese hwetupukanana mumvura huve pasi pe100 CFU/ml, conductivity inofanira kunge iri pasi pe0.1μS/cm, zvese zvakanyungudutswa zvinofanira kunge zviri pasi pe200 mg/L, uye mvura inorema inofanira kunge iri pasi pe100 mg/L, huwandu hwesimbi hunofanira kunge huri pasi pe0.1 μg/L, nezvimwewo.

Kuti vagadzire mvura yakachena kwazvo yeRO, inosangana nezvinodiwa zvepasi rose zvechitupa, makambani makuru anoshandisa tekinoroji yepamusoro ye reverse osmosis membrane uye tekinoroji ye multiple pass RO system kuvandudza mhando yemvura ye hemodialysis.Masisitimu ekuchenesa mvura eRONekushandisa otomatiki monitoring uye alarm systems, zvinogona kuona kusarongeka kwemhando yemvura nekukurumidza, zvichiita kuti mvura yeRO irambe yakachengeteka uye inoramba ichimanikidzwa.
Semugadziri wemidziyo yekuchenesa mvura yeRO ine matekinoroji epamusoro-soro ane patent, Wesley anoshandisa maDow membranes ekutanga, ayo anovimbisa kunaka kwemvura uye kugadzirwa kwemvura kwakasimba, uye anoshandisa sisitimu yemvura yeTriple Pass kuchenesa mvura yeRO inodzokororwa kaviri kuti ibudise mvura yeRO yakachena kwazvo. Munguva yekugadzira mvura yakachena kwazvo, online residual chlorine/hardness monitor uye leak detector yemuchina wedu iri kushanda. Maapplication aya anoita kutisisitimu yemvura yedialysisyakavimbika uye inoshanda zvakanaka, kunyangwe inoshandiswa munzvimbo dzine mvura isina kunaka senge Africa, ichirumbidzwa zvikuru. Chimwe chinhu chezvivakwa chinofanira kutaurwa ndechekuti rudzi rwemvuramuchina wemvura weRO unotakurikairipo.
