1. Kuwonongeka kwa madzi olimba pakuchapa zovala
Kuuma kwa madzi kumatanthauza zomwe zili mumchere wosungunuka m'madzi, ndiko kuti, zomwe zili mu mchere wa calcium ndi mchere wa magnesium.Zomwe zili pamwambazi, zimakhala zolimba kwambiri, mosiyana.GPG ndi gawo la kuuma kwa madzi, 1GPG imatanthauza kuti zomwe zili mu ma ion olimba (calcium ndi magnesium ions) mu galoni imodzi yamadzi ndi njere imodzi.
Mulingo wamadzi olimba:
Malinga ndi muyezo wa American WQA (Water Quality Association), kuuma kwamadzi kumagawidwa m'magulu 6.0 - 0.5GPG ndi madzi ofewa, 0.5 - 3.5GPG ndi ovuta pang'ono, 3.5 - 7.0GPG ndi olimba kwambiri, 7.0 - 10.5GPG ndi madzi ovuta, 10.5 - 14.0GPG ndi ovuta kwambiri, ndipo pamwamba pa 14.0GPG ndi ovuta kwambiri.
Madzi olimba ochapira zovala amatha kukhala ndi zotsatirapo zosafunikira.Ma ion calcium ndi magnesium m'madzi olimba amayikidwa pansalu, zomwe zimapangitsa kuti nsalu zoyera zikhale ndi imvi.Zidzakhudza kuyera ndi kumverera, ndikupangitsa mtundu wa nsalu kuzimiririka ndikutaya mawonekedwe ake.Kuphatikiza apo, ayoni a calcium ndi magnesium amayikidwa pansalu, ndipo kumamatira ku ulusi kumakhala kolimba.Ndikovuta kutsuka ma ion a calcium ndi magnesium omwe amamatira pansalu ndikupangitsa kuti nsaluyo ikhale yoyera.Njira yabwino yotsuka nsalu zoyera m'madzi olimba opanda imvi kapena kucheperapo ndikuyamba kusamala.
Chitsulo sichipezeka m'madzi ngati chitsulo, koma ngati ion kapena chitsulo.Madzi amtunduwu akatenthedwa kutsuka nsalu, dzimbiri (iron hydroxide) limapangidwa ndikuyikidwa pansalu ngati mawanga a bulauni.Zidzapangitsa kuti nsalu zoyera zikhale zachikasu zonse ndikupangitsa kuti nsalu zamitundu ziwonongeke.Kuchotsa masikelo achitsulowa, chithandizo chapadera ndi asidi chimafunika.Choopsa china chachitsulo m'madzi ndikuti chimakhala ndi chothandizira pakuwonongeka kwa hypochlorite ndi hydrogen peroxide.Mu siteji ya bleaching, ngati ayoni achitsulo alipo mu gawo lina la nsalu, amayambitsa kuwonongeka kwamphamvu kwa hypochlorite kapena hydrogen peroxide, zomwe zimapangitsa kuti makutidwe a okosijeni am'deralo akhale achiwawa ndikupangitsa kuti nsaluyo iwonongeke.
2. Kusamba zofunika madzi
Kumwa madziMiyezo yabwino, zizindikiro zina zamakina ndi izi:
Mtengo wa PH: 6.5 - 8.5
Kuuma kwathunthu: ≤446ppm
Iron: ≤0.3mg/L
Manganese: ≤0.1mg/L.
Kusamba madzizofunika:
Mtengo wa PH: 6.5 ~ 7
Kulimba kwathunthu: ≤25ppm (makamaka 0)
Iron: ≤0.1mg/L
Manganese: ≤0.05mg/L
Madzi apampopi nthawi zambiri amagwiritsidwa ntchito mu dipatimenti yochapa zovala m'mahotela akutawuni.Madzi apampopi amapangidwa motsatira muyezo wapakhomo wogwiritsa ntchito madzi, ndipo palibe vuto kuti anthu amwe.Koma monga madzi ochapira, mwachiwonekere si abwino.Choncho, kuti mukwaniritse zofunikira zotsuka zamtundu wapamwamba, madzi osamba ayenera kutsukidwa pamlingo wina.
