Nekuda kwekuzivikanwa kukuru kwezvishandiso zvekuchenesa mvura, vanhu vazhinji vanoziva kuti panogona kunge paine matambudziko nemvura yepombi. Nekuda kwezvikonzero zvakasiyana-siyana, pane musiyano mumhando yemvura kumba. Vamwe vanhu vakabvunza kuti mushure mekunwa mvura yepombi kwemakore akawanda, hapana dambudziko, zvakakosha here kuisa chishandiso chekuchenesa mvura? Imhaka yekuti vemabhizinesi vanowedzera manyepo uye vanonyengedza vanhu? Takafukura chokwadi tikaona kuti vanhu vazhinji vakakanganisa.
Mushure mekunwa mvura yemupombi kwemakore akawanda kudaro, vanhu vazhinji vanorarama hupenyu hwakajairika pasina kukanganiswa, uye hapana chikonzero chekuisa muchina wekuchenesa mvura. Aya ndiwo mafungiro evamwe vanhu, kana zvichidikanwa kuisa muchina wekuchenesa mvura ndicho chinodiwa chedu pakunwa mvura. Mvura yemupombi yakasviba zvishoma inogona kunge isina simba kune vanhu vazhinji, asi kune vamwe inogona. Ehe, kune dzimwe nzvimbo dzisiri kungova kusvibiswa kwechiedza.
1) Zvinodiwa here kuisa muchina wekuchenesa mvura pamba?
Zvinodiwa, nekuti mvura iyi ine ngura, madhaka, tsvina, colloids, zvinhu zvakasimba zvakasungirirwa, nezvimwewo, kunyangwe mvura iyi ichifanira kufashaidzwa isati yanwiwa, kune mabhakitiriya anodzivirira kupisa kwakanyanya, uye zvinhu zvinokuvadza zvakaita sesimbi dzinorema nechlorine hazvigone kufashaidzwa zvachose. Kana yabviswa, inogonawo kugadzira kenza. Saka, zvakakosha kuisa mudziyo wekuchenesa mvura kumba, usingangogoni kungosefa tsvina nemabhakitiriya mumvura chete, asiwo kuderedza scale nematombo. Uyezve, mudziyo wekuchenesa mvura unoshandiswa kwenguva yakareba, uye zviri nani kutsiva mvura filter core nguva dzose. Mvura inobva mumuchina wekuchenesa mvura inogona kushandiswa kwete chete pakunwa, asiwo pakubika, izvo zvinochengetedza kunetseka nemari.
2) Ndezvipi zvisiri kunzwisiswa pakutenga michina yekuchenesa mvura?
a) Kana nhamba yematanho yakakwira, kunyatsoita kupfapfaidza kunowedzera
Zvinoshandiswa pakuchenesa mvura mudzimba zvinozivikanwa ndezvinoti ultrafiltration uye RO reverse osmosis. Kunyatsonatswa kwe ultrafiltration membrane kunogona kubvisa tsvina, mabhakitiriya, mavhairasi, nezvimwewo mumvura. RO reverse osmosis membrane inogona kusefa zvinhu mumvura, kunyangwe zvinhu zvese zvechisikigo zvinogona kusefa, uye kunyatsonatswa kwe filter kunogona kusvika ka100 pane ultrafiltration membrane, asi kunyangwe giredhi rechigumi re ultrafiltration membrane harina kunaka segiredhi rechitatu re RO membrane, saka harisi. Kana yakakwira, zviri nani.
b) Kana mutengo wacho uchidhura zvakanyanya, zvinoita kuti mhedzisiro yekusefa ive nani
Vamwe vatengesi vasina hunhu vanoonekwa semichina ye ultrafiltration, asi vanoshandiswa kuita sevanochenesa mvura ye reverse osmosis. Mutengo wacho unodhura, asi haugone kuita sefa ye reverse osmosis filter. Saka usangotarisa mutengo chete, asiwo zvinhu zviri mu filter yacho, kuitira kuti usanyengerwa.
