Amanzi ahlanzekile abhekisela ku-H2O ngaphandle kokungcola, okungamanzi ahlanzekile noma amanzi ahlanzekile okwesikhashana.Amanzi ahlanzekile futhi ahlanzekile angenakho ukungcola noma amagciwane.Yenziwe ngamanzi ahlangabezana nezindinganiso zokuhlanzeka kwamanzi okuphuza asekhaya ngendlela eluhlaza ye-electrodialyzer, indlela ye-ion exchanger, indlela ye-osmosis ehlehlayo, indlela yokuwahluza, nezinye izindlela zokucubungula ezifanele.Ungaphuza ngqo.
Eminyakeni yamuva nje, ngokuthuthuka okuqhubekayo kwezinga lamasiko abantu, izinga lokuphila, nezinga lokusebenzisa, abantu bashintshile besuka ezidingweni zokuphila eziyisisekelo ezifana nokudla nezingubo baphishekela imikhiqizo engokwemvelo nenempilo yokuphila kanye nezindlela zokuphila.Kumanzi okuphuza abalulekile empilweni yabantu, ukusebenza kwawo kusobala kakhulu.Njengamanje, ingxenye yemakethe yamanzi okuphuza embonini yokudla neziphuzo isifinyelele ku-40%.Phakathi kwazo, amanzi ahlanzekile ahlanganisa ngaphezu kwe-1/3.Ngakho-ke, yonke inqubo yokukhiqiza amanzi ahlanzekile idinga ukugadwa futhi iqashwe ngesikhathi sangempela ukuze kuqinisekiswe ukuthi amanzi ahlanzekile afakwa emakethe ayimikhiqizo ehlanzekile, ehlanzekile futhi efanelekayo ehambisana nemithetho neziqondiso ezifanele.
Ngenxa ye-conductivity ephansi yamanzi ahlanzekile, ama-flowmeters ajwayelekile kagesi awakwazi ukukala.
Ngokungeziwe kuma-flowmeters we-electromagnetic avame ukusetshenziswa, i-Sinomeasure ingahlinzeka ngama-flowmeters we-turbine afakwe ngocingo noma ama-flowmeters we-ultrasonic ngaphandle kokuphulwa kwepayipi ngokuvumelana nezidingo zamakhasimende zesilinganiso samanzi ahlanzekile.
