1.Ukususela kumgaqo wokucoca we-ultrafiltration inwebu yokucoca amanzi (UF) kunye ne-RO yokucoca amanzi, zombini zihluza amanzi nge-polymer material membrane.
Susa ukungcola emanzini.

2. Ukususela ekuchanekeni kwe-filtration ye-membrane ye-ultrafiltration kunye ne-membrane ye-RO, ukuchaneka kwe-filtration kwezi zibini zihluke.Ukuchaneka kokucoca kwenwebu ye-ultrafiltration yi-0.01 microns,
Ukuchaneka kokucoca kwe-RO membrane yi-0.0001 microns.

Amanzi ompompo ahlanjululwe nge-membrane ye-ultrafiltration anokususa ukungcola okuyingozi njengentlenga, i-rust, i-colloid kunye ne-bacterial microorganisms,
Ngexesha elifanayo gcina iiminerali zokuqala kwaye ulandele izinto emanzini.

Emva kokuhluzwa kwe-membrane ye-RO kunye nokucocwa, amanzi acocekileyo aneemolekyuli zamanzi kuphela asele afunyenwe, angenako ukususa ngokufanelekileyo intlenga, umhlwa,
I-Colloids, ibhaktiriya kunye nobunye ukungcola okuyingozi, kodwa kwakhona ukususa izitshabalalisi, isinyithi esinzima, njl.njl. I-Olansi RO Isicoci saManzi i-W4
Kukwakho nenqaku lokucoca umkhondo emva kokuhluzwa kwe-membrane ye-RO, yongeza iiminerali kunye nokulandela izinto eziluncedo kumzimba womntu.Eyona ikhethekileyo yistrontium.
I-Strontium ilinganisa ukufunxwa kwe-sodium kunye ne-calcium emzimbeni.

I-3.I-Ultrafiltration inwebu yokucoca amanzi acocekileyo ngokuqhelekileyo isebenzisa uxinzelelo lwamanzi ompompo ukwenza ukuhluza ngaphandle kombane.Isicoci samanzi e-RO kuba ukuchaneka kokucoca kuphezulu kakhulu,
Ukucoca kunye nokucocwa akukwazi ukufezekiswa ngokusebenzisa uxinzelelo lwamanzi lwamanzi ompompo ngokwawo, ngoko ke ngokuqhelekileyo kufuneka ukuba unikwe amandla kunye nokunyanzeliswa ukufezekisa ukucocwa kunye nokucocwa kwamanzi ompompo.
Ukongeza, izicoci zamanzi ze-RO zihlala zivelisa amanzi amdaka.Ngokuphuculwa kunye nokuphuculwa kweteknoloji kwiminyaka yakutshanje, umlinganiselo wamanzi amdaka we-RO zokucoca amanzi uncitshisiwe ukusuka kwi-3: 1 ukuya kwi-2: 1 okanye 1: 1.
