Wonke amanzi okuphuza azohlanzwa ngamanzi omthombo, ngokuvamile okuyichibi lamanzi ahlanzekile, umfula, umthombo wamanzi, noma ngezinye izikhathi ngisho nomfudlana kanye namanzi omthombo angaba sengozini yokungcoliswa yiphutha noma ngamabomu kanye nezinguquko ezihlobene nesimo sezulu noma zesizini.Ukuqapha izinga lamanzi omthombo bese kukwenza ukwazi ukubona izinguquko enqubweni yokwelapha.
Isinyathelo sokuqala: Ukwelashwa kwangaphambili kwamanzi omthombo, okubizwa nangokuthi i-Coagulation and Flocculation, izinhlayiya zizohlanganiswa namakhemikhali ukuze zakhe izinhlayiya ezinkulu, khona-ke izinhlayiya ezinkulu zizocwila phansi.
Isinyathelo sesibili i-Filtration, ngemva kokufakwa kwe-sedimentation ekwelapheni kwangaphambili, amanzi ahlanzekile azodlula ezihlungi, ngokuvamile, isihlungi sakhiwe ngesihlabathi, amatshe, namalahle) kanye nosayizi we-pore.Ukuze kuvikelwe izihlungi, sidinga ukuqapha i-turbidity, okuqinile okumisiwe, i-alkalinity namanye amapharamitha ekhwalithi yamanzi.
Isinyathelo sesithathu inqubo yokubulala amagciwane.Lesi sinyathelo sibaluleke kakhulu, ngemva kokuhlungwa kwamanzi, kufanele sengeze isibulala-magciwane emanzini ahlungiwe, njenge-chlorine, i-chloramine, kuwumyalelo wokubulala amagciwane asele, amagciwane, namagciwane, siqinisekise ukuthi amanzi aphephile uma eyiswa ekhaya ngamapayipi.
Isinyathelo sesine ukusatshalaliswa, kufanele silinganise i-pH, i-turbidity, ubulukhuni, i-chlorine esele, i-conductivity(TDS), bese sizokwazi ubungozi obungaba khona noma sisongela impilo yomphakathi ngesikhathi.Inani le-chlorine eliyinsalela kufanele libe ngaphezu kuka-0.3mg/L lapho likhishwa ngamapayipi embonini yamanzi okuphuza, futhi libe ngaphezu kuka-0.05mg/L ekupheleni kwenethiwekhi yamapayipi.I-turbidity kumele ibe ngaphansi kwe-1NTU, inani le-pH liphakathi kuka-6.5~8,5, ipayipi lizogqwala uma inani le-pH lingaphansi kuka-6.5pH kanye nesikali esilula uma i-pH ingaphezu kuka-8.5pH.
Kodwa-ke okwamanje, umsebenzi wokuqapha izinga lamanzi ngokuyinhloko wamukela ukuhlolwa kwezandla emazweni amaningi, okunokushiyeka okuningi kokushesha, ukuphelela, ukuqhubeka kanye nephutha lomuntu njll.Isistimu yokuqapha izinga lamanzi e-inthanethi ye-BOQU ingaqapha izinga lamanzi amahora angu-24 kanye nesikhathi sangempela.Iphinde inikeze ulwazi olusheshayo nolulungile kubathathi izinqumo ngokusekelwe ekushintsheni kwekhwalithi yamanzi ngesikhathi sangempela.Ngaleyo ndlela ihlinzeka abantu ngekhwalithi yamanzi anempilo naphephile.
