Izinga lamanzi
Izinga lamanzi e-Kerava lihlangabezana nazo zonke izidingo zekhwalithi ngokuvumelana nomthetho woMnyango Wezindaba Zomphakathi Nezempilo. Amanzi okuphuza ezakhamuzi zaseKerava angamanzi aphansi okwenziwa asezingeni eliphezulu, angasebenzisi amakhemikhali engeziwe ekucutshungulweni kwawo. Awudingi ngisho nokwengeza i-chlorine emanzini. I-pH yamanzi kuphela ephakanyiswa kancane nge-limestone yemvelo embiwa eFinland, lapho amanzi ehlungwa khona. Ukugqwala kwamapayipi amanzi kungavinjelwa ngale ndlela.
Emanzini ahlinzekwa yi-Keski-Uusimaa Vedi, amanzi angaphansi komhlaba emvelo abalelwa ku-30%, kanti amanzi angaphansi komhlaba okwenziwa afinyelela ku-70%. Amanzi angaphansi komhlaba okwenziwa atholakala ngokumunca amanzi e-Päijänne ekhwalithi enhle kakhulu emhlabathini.
Izinga lamanzi liyahlolwa ngokuhambisana nohlelo locwaningo lokulawulwa kwamanzi asekhaya, olwenziwa ngokubambisana neziphathimandla zezempilo. Amasampula amanzi avela e-Kerava athathwa njengomsebenzi wesikhungo sokuphakela amanzi sase-Kerava.

Ukuqina kwamanzi kusho ukuthi angakanani amaminerali athile emanzini, ikakhulukazi i-calcium ne-magnesium. Uma ziningi, amanzi achazwa ngokuthi aqinile. Ukuqina kungaqashelwa yiqiniso lokuthi kunediphozithi ye-lime eqinile phansi kwezimbiza. Ibizwa nge-boiler stone. (Vesi.fi)
Amanzi kampompi e-Kerava athambile kakhulu. Amanzi aqinile aphakathi nendawo atholakala ezindaweni ezisenyakatho-mpumalanga yeKerava. Ukuqina kunikezwa ngamadigri aseJalimane (°dH) noma ama-millimoles (mmol/l). Amanani okuqina amaphakathi akalwe ku-Kerava ayahluka phakathi kuka-3,4-3,6 °dH (0,5-0,6 mmol/l).
Isampula nokuzimisela kokuqina
Ukuqina kwamanzi kunqunywa nyanga zonke mayelana nokuqapha izinga lamanzi. Izinga lamanzi liyahlolwa ngokuhambisana nohlelo locwaningo lokulawulwa kwamanzi asekhaya, olwenziwa ngokubambisana neziphathimandla zezempilo.
Umthelela wokuqina kwamanzi ezintweni zikagesi zasendlini
Amanzi aqinile adala izinhlobo eziningi zokulimala. Idiphozithi ye-lime inqwabelana ohlelweni lwamanzi ashisayo, futhi ama-grate emisele yaphansi ayavinjelwa. Kufanele usebenzise okokuhlanza okwengeziwe lapho uwasha, futhi imishini yekhofi kufanele ihlanzwe nge-limescale izikhathi eziningana. (vesi.fi)
Ngenxa yamanzi athambile, ngokuvamile asikho isidingo sokwengeza usawoti othambisayo emshinini wokuwasha izitsha we-Kerava. Nokho, imiyalelo yomkhiqizi wedivayisi kufanele ilandelwe. I-limescale eqoqwe ezintweni zasendlini ingasuswa nge-citric acid. I-Citric acid nemiyalo yokusetshenziswa kwayo ingatholakala ekhemisi.
Ukuqina kwamanzi kufanele kucatshangelwe lapho kufakwa okokuhlanza izingubo. Imiyalo yomthamo ingatholakala ohlangothini lwephakheji yokuhlanza.
Iketela lekhofi namanzi kufanele liphathwe ngezikhathi ezithile ngokubilisa isixazululo seviniga yasendlini (1/4 uviniga wasendlini kanye namanzi angu-3/4) noma isixazululo se-citric acid (isipuni esingu-1 ilitha lamanzi) ngokusebenzisa idivayisi. Emva kwalokhu, khumbula ukubilisa amanzi ngomshini izikhathi ezingu-2-3 ngaphambi kokusebenzisa idivayisi futhi.
Isikali sokuqina kwamanzi
Ukuqina kwamanzi, °dH Incazelo ngamazwi 0-2,1 Ithambile kakhulu 2,1-4,9 Ithambile 4,9-9,8 Iqinile emaphakathi 9,8-21 I-Aquarius > 21 Kunzima kakhulu

E-Kerava, i-asidi yamanzi kampompi icishe ibe ngu-7,7, okusho ukuthi amanzi ane-alkaline kancane. I-pH yamanzi angaphansi komhlaba eFinland ingama-6-8. Inani le-pH lamanzi ompompi we-Kerava lilungiswa ngosizo lwe-limestone phakathi kuka-7,0 no-8,8, ukuze izinto zamapayipi zingagqwali. Isidingo sekhwalithi ye-pH yamanzi asekhaya ngu-6,5-9,5.
I-pH yamanzi Incazelo ngamazwi <7 Omuncu 7 Ukungathathi hlangothi >7 I-alkaline -
I-fluorine, noma ebizwa ngokufanelekile nge-fluoride, iyisici esibalulekile sokulandelela abantu. Okuqukethwe kwe-fluoride ephansi kuxhunywe nama-caries. Ngakolunye uhlangothi, ukudla ngokweqile kwe-fluoride kubangela ukulimala koqweqwe lwawo emazinyweni nasekuqineni kwamathambo. Inani le-fluoride emanzini kampompi we-Kerava liphansi kakhulu, kuphela i-0,3 mg/l. E-Finland, okuqukethwe kwe-fluoride emanzini ampompi kufanele kube ngaphansi kuka-1,5 mg/l.
