Mamiriro eindasitiri uye hunhu hwemvura yakasviba yeganda
Muhupenyu hwezuva nezuva, zvigadzirwa zvematehwe zvakaita semabhegi, shangu dzematehwe, mbatya dzematehwe, masofa ematehwe, nezvimwewo zviri kwose kwose. Mumakore achangopfuura, indasitiri yematehwe yakawedzera nekukurumidza. Panguva imwe chete, kuburitswa kwemvura yakasviba yeganda kwave zvishoma nezvishoma kuva chimwe chezvinhu zvakakosha zvinokonzera kusvibiswa kwemaindasitiri.
Kuchenesa ganda kunowanzo sanganisira matanho matatu ekugadzirira, kusvina ganda uye kupedzisa. Muchikamu chekugadzirira ganda risati rapiswa, tsvina inonyanya kubva mukusuka, kunyorova, kubvisa bvudzi, kuisa lime, kubvisa mafuta, kunyorovesa uye kubvisa mafuta; tsvina huru inosanganisira marara echisikigo, marara asina organic uye organic compounds. Mvura yakasviba iri muchikamu chekuchenesa ganda inonyanya kubva mukusuka, kusvina, uye kuisa ganda; tsvina huru imunyu isina organic uye heavy metal chromium. Mvura yakasviba iri muchikamu chekupedzisa inonyanya kubva mukusuka, kusvina, kudhaya, kuisa mafuta uye kubvisa guruva retsvina, nezvimwewo. Zvinosvibisa zvinosanganisira madhayi, mafuta uye organic compounds. Naizvozvo, mvura yakasviba yeganda ine hunhu hwehuwandu hwemvura yakawanda, kuchinja kukuru kwehunhu hwemvura uye huwandu hwemvura, kusvibiswa kwakanyanya, alkalinity yakawanda, chroma yakawanda, huwandu hwakawanda hwezvakasimba zvakamiswa, kuora kwakanaka, nezvimwewo, uye ine chepfu yakati.
Mvura ine sarufa: Mvura inobvisa ganda inogadzirwa nekubvisa bvudzi kubva muash-alkali panguva yekuchenesa ganda uye mvura inobviswa kubva mukuchenesa;
Kubvisa mafuta mumvura yakasviba: Mukubvisa mafuta paganda uye pakugadzira mvere, mvura inobuda inogadzirwa nekuchenesa ganda risina kucheneswa nemafuta ne surfactant pamwe nemvura yakasviba inoenderana nekugeza.
Mvura yakasviba ine chromium: doro re chrome rinogadzirwa mu chrome tanning uye chrome retanning processes, uye mvura yakasviba inoenderana nayo mu washing process.
Mvura yakasviba yakakwana: izwi rekuti mvura yakasviba yakasiyana-siyana inogadzirwa nemakambani ekuchenesa ganda nekugadzira mvere kana nzvimbo dzekugadzirisa, uye inoburitswa zvakananga kana zvisina kunanga kumapurojekiti ekuchenesa mvura yakasviba (akadai semvura yakasviba inogadzirwa, tsvina yemumba mumafekitori).
