A Uhlelo lokwelashwa kwamanzi omakhemikhalikuyingqalasizinda ebalulekile enqubeni yokukhiqiza yezemithi. I-Enzelwe ngokuqondile ukukhiqiza amanzi asezingeni eliphakeme anamathela ezindinganisweni eziqinile zokulawula kanye nezinga lekhwalithi yomkhakha wezemithi.

Uhlelo luvame ukuhlanganisa izigaba zokwelashwa eziningi. Izinqubo zokuhlekisa zivame ukuba yisinyathelo sokuqala, esingafaka ukufombula ukuze siqede ama-solids amisiwe nezinkinga. Lokhu kulandelwa amasu anjenge-Ion Exchange ukuguqula ukwakheka kwamanzi ionic futhi ususe amaminerali athile. I-Reverse Osmosis ingesinye isigaba esibalulekile, lapho i-membrane evunyelwe ye-semicial isetshenziselwa ukuhlukanisa usawoti ocijile, izinsimbi ezisindayo, nengxenye ebalulekile yezinto eziphilayo eziphilayo kanye nezinto ezingcolile ezivela emanzini.

Amanzi aphethwe abuye ahlanzwa ngezinqubo ezinjengokufaka inzalo ye-ultraviolet ukuqinisekisa ukungasebenzi kwanoma yiziphi izingqinamba ezisele ezisele nezinqubo zokususa ama-endotoxin ukunciphisa ubukhona bama-pyrogens. Umkhiqizo wokugcina, ongahlanzwa ngamanzi noma amanzi omjovo, ngokuya ngezidingo ezithile, asetshenziswa ezinhlelweni ezahlukahlukene zemithi. Kusetshenziswa ekwakhekeni kwezidakamizwa, njenge-solvent yezithako ezisebenzayo zemithi, nasekuhlanzeni nasekuhlalweni kwemishini yokukhiqiza nezinsizakusebenza.

Ukuqinisekisa ukusebenza okungaguquki kanye nokwethenjwa kweUhlelo lokwelashwa kwamanzi omakhemikhali, ukuqapha njalo, ukugcinwa, kanye nezinqubo zokuqinisekisa ziyaqaliswa. Lokhu kufaka phakathi ukuhlolwa kwekhwalithi yamanzi ejwayelekile, ukuhlolwa kanye nokubuyiselwa kwemithombo yezindaba ye-filltration kanye nolwelwesi, kanye nokucwaningwa kwama-membranes, kanye nokuhlolwa kohlelo oluphelele ukuze kuqinisekiswe ukuhambisana ne-International Pharmacopoeia kanye nemihlahlandlela yokulawula. Uhlelo oluklanywe kahle futhi olugcinwe kahle lokwelashwa kwamanzi lubalulekile ekwakhiweni kwemikhiqizo ephephile, esebenzayo, nekhwalithi ephezulu yemithi.
