Seawater Desalination inzira yekushandura mvura yemunyu kuita mvura inonwika, inonyanya kuwanikwa kuburikidza neanotevera tekinoroji misimboti:

1. Reverse osmosis (RO): RO parizvino ndiyo inonyanya kushandiswa tekinoroji yekubvisa mvura yegungwa. Nheyo iyi ndeye kushandisa hunhu hwe semi permeable membrane uye kushandisa kumanikidza kubvumira mvura yemunyu kuti ipfuure nemu membrane. Mamorekuru emvura anogona kupfuura nepakati pe membrane, nepo munyu uye kumwe kusvibiswa kwakanyungudutswa mumvura kunovharirwa kune rimwe divi re membrane. Nenzira iyi, mvura yakapfuura nemu membrane inova mvura yakachena. Reverse osmosis tekinoroji inogona kunyatso bvisa munyu yakanyungudika, simbi inorema, uye organic zvinhu kubva mumvura.

2. Multi stage flash flash evaporation (MSF): Multi stage flash evaporation tekinoroji inoshandisa kukurumidza kubuda kwemaitiro emvura yegungwa pakumanikidzwa kwakaderera. Mvura yegungwa inotanga kupiswa kune imwe tembiricha, yozo“penya” mumakamuri akawanda evaporation nekuderedza kudzvanywa. Pane imwe neimwe nhanho, iyo mhute yemvura inoputika inodzorwa uye inounganidzwa kuti igadzire mvura yakachena, nepo yakasara yakanyungudutswa mvura yemunyu inoramba ichitenderera muhurongwa hwekugadziriswa.

3. Multi effect distillation (MED): Multi effect distillation tekinoroji inoshandisawo musimboti wekubuda. Mvura yegungwa inodziiswa mumaheater akawanda, zvichiita kuti inyunguduke ichipinda mumhute yemvura. Utsi hwemvura hunozotonhodzwa mucondenser kuita mvura yakachena. Kusiyana ne-multi-stage flash evaporation, multi-effect distillation inovandudza kushanda kwesimba nekushandisa kupisa kunoburitswa panguva yekubuda kwemhepo.

4. Electrodialysis (ED): ED inoshandisa munda wemagetsi kutamisa ions mumvura, nokudaro kuparadzanisa munyu nemvura yakachena. Musero re electrolytic, nzvimbo yemagetsi pakati peanode ne cathode inoita kuti maion akanaka uye akaipa afambe akananga kumatanda maviri zvakateerana, uye mvura yakachena inounganidzwa parutivi rwekathodhi.

Aya matekinoroji ega ega ane zvayakanakira nezvaanokanganisa, uye akakodzera kune akasiyana matsime emvura mamiriro uye zvinodiwa. Kuenderera mberi kwekuvandudza tekinoroji yekubvisa mvura yegungwa kwakapa mhinduro dzinoshanda kudambudziko rekushaikwa kwemvura pasi rose.

Yantai Jietong Mvura Kurapa Technology Co., Ltd ine zvikwata zvakasimba zvehunyanzvi kugadzira dhizaini yevatengi zvinoenderana nemamiriro chaiwo evatengi.
