Unhu hwemvura
Hunhu hwemvura yeKerava hunosangana mune zvese zvinodiwa zvemhando maererano nemutemo weBazi reSocial Affairs uye Hutano. Mvura yekunwa yevagari veKerava imvura yemhando yepamusoro yepasi, isingashandisi mamwe makemikari mukugadzirisa kwayo. Iwe hautombodi kuwedzera chlorine kumvura. Iyo pH yemvura chete ndiyo inosimudzwa zvishoma neraimestone yechisikigo inocherwa kubva kuFinland, kuburikidza iyo mvura inosefa. Kuora kwepombi dzemvura kunogona kudzivirirwa nenzira iyi.
Pamvura inopiwa naKeski-Uusimaa Vedi, mvura yakasikwa yepasi inokwana 30%, uye mvura yepasi yakagadzirwa inosvika makumi manomwe muzana. Artificial pasi pemvura inowanikwa nekutora zvakanaka kwazvo mvura yePäijänne muvhu.
Hunhu hwemvura hunoongororwa maererano nechirongwa chekutsvaga chekudzora mvura yemumba, icho chakaitwa mukubatana nevakuru vehutano. Sampuli dzemvura kubva kuKerava dzinotorwa seKerava nzvimbo yekugovera mvura yebasa pachayo.

Kuoma kwemvura kunotarwa mwedzi wega wega maererano nekuongororwa kwehutano hwemvura. Hunhu hwemvura hunoongororwa maererano nechirongwa chekutsvaga chekudzora mvura yemumba, icho chakaitwa mukubatana nevakuru vehutano.
Mhedzisiro yekuoma kwemvura pamidziyo yemumba
Mvura yakaoma inokonzera marudzi akawanda ekukuvadza. Lime deposits inoungana muhurongwa hwemvura inopisa, uye magirasi emvura yepasi anovharika. Iwe unofanirwa kushandisa yakawanda detergent paunenge uchiwacha, uye michina yekofi inofanirwa kucheneswa limescale kakawanda. (vesi.fi)
Nekuda kwemvura yakapfava, kazhinji hapana chikonzero chekuwedzera munyu unopfavisa kune Kerava dishwasher. Zvisinei, mirairo yemugadziri wemudziyo inofanira kuteverwa. Limescale yakaunganidzwa mumidziyo yemumba inogona kubviswa ne citric acid. Citric acid nemirayiridzo yekushandiswa kwayo inogona kuwanikwa kubva ku pharmacy.
Kuoma kwemvura kunofanirwa kuverengerwa kana uchitora detergent yekuwachira. Mirayiridzo yedosing inogona kuwanikwa padivi redetergent package.
Ikoji yekofi nemvura inofanira kurapwa nguva nenguva nekubikira mhinduro yevhiniga yemumba (1/4 yevhiniga yeimba uye 3/4 mvura) kana citric acid solution (1 teaspoon per litre yemvura) kuburikidza nemudziyo. Mushure meizvi, yeuka kubika mvura kuburikidza nemudziyo 2-3 nguva usati washandisa chigadzirwa zvakare.
