Maitiro anga aripo iripo papasi kwemabhiriyoni emakore muchimiro chemvura uye zvinoita sekunge pakupedzisira mamwe masayendisiti akazviita kuti zvive zvakanaka uye zvinochengetedza kugona kushandura mvura ine munyu kuita mvura yekunwa vachishandisa simba rezuva.
Chikwata chinobva kuMIT (Massachusetts Institute of Technology) muUnited States chaunza inotakurika desalination system kuti ishandiswe chero painodiwa. Chikwata ichi chakaparura chirongwa ichi mumakwikwi anoitiswa neUSAID kukurudzira mhinduro dziri nani kune nguva dzekushomeka kwemvura mune dzimwe nguva munyika dzichiri kusimukira.
Kuti uwane mubairo wekutanga we $ 140.000, vatori vechikamu vaifanira kuratidzira kwete chete kuti zvigadzirwa zvavo zvakashanda, asi iyo yaive ine hupfumi, inochengetedza zvakatipoteredza uye inoshandisa simba.
Zano rechikwata ichi inoenderana nekushandisa maseru ezuva kubhadharisa boka remabhatiri anopa simba kumuchina we electrodialysis uyo inobvisa munyu kubva mumvura uye inoita kuti inwe uye yagadzirira kunwiwa.
David L. Chander anotsanangura mashandiro ainoita: «Electrodialysis inoshanda nekupfuura rwizi rwemvura pakati pemagetsi maviri nemhosva dzakapesana. Nekuda kwesimbi yakanyungudutswa iri mumvura ine ioni dzakanaka uye dzisina kunaka, ma electrode "anosundira" maion kunze kwemvura ichisiya mvura yekunwa iri pakati perukova. Nhevedzano yeganhu inopatsanura chii chiripo ikozvino chemvura isina munyu kubva kune icho chine iyo.".
Imwe yeakanyanya kunaka ehurongwa uhwu kushandiswa kwe membranes nekuti nekuti vari pasi peiyo electrodialysis system haitsigire yakawanda mutoro uye kumanikidza izvo zvinovatendera kugara kwenguva refu uye zvinoda kushomeka kuchengetedzwa. Izvo zvinodikanwa kuti utarise kuti idzi tembiricha dzine mutengo wakakwira.
Chandler anoshuma izvo ino system inogona kushandura 90 muzana yemvura yemunyu kuita yakagadzirira-kunwa mvura, iyo iri pachayo yakakwira kwazvo muzana ichienzaniswa nemamwe masisitimu senge reverse osmosis.
