Xa ukhetha isicoci samanzi esingaphantsi kwe-sink, kukho iiparamitha ezininzi ekufuneka ziqwalaselwe:

1. **Uhlobo lwesicoci saManzi:**
- Kukho iintlobo ezininzi ezikhoyo kuquka i-Microfiltration (MF), i-Ultrafiltration (UF), i-Nanofiltration (NF), kunye ne-Reverse Osmosis (RO). Xa ukhetha, qwalasela itekhnoloji yokucoca, ukusebenza kakuhle kokucoca, ukukhululeka kokutshintshwa kwekhatriji, ixesha lokuphila, kunye neendleko zokutshintsha.

2. **Uhluzo oluncinci (MF):**
-Ukuchaneka kokucoca ngokuqhelekileyo kuphakathi kwe-0.1 ukuya kwi-50 microns. Iindidi eziqhelekileyo ziquka iikhatriji ze-PP zokucoca, iikhatriji ze-carbon filter esebenzayo, kunye neekhatriji ze-ceramic filter. Isetyenziselwa ukuhluza okurhabaxa, ukususa amasuntswana amakhulu njengentlenga kunye nomhlwa.

– Ukungalungi kubandakanya ukungakwazi ukususa izinto ezinobungozi ezifana neebhaktheriya, ukungakwazi ukucoca iikhatriji zokucoca (ezihlala zilahlwa), kunye nokutshintshwa rhoqo okufunekayo.

3. **Uhluzo lweUltrafiltration (UF):**
-Ukuchaneka kokucoca ukusuka kwi-0.001 ukuya kwi-0.1 microns. Isebenzisa itekhnoloji yokwahlukana kwenwebu yoxinzelelo ukususa umhlwa, intlenga, iicolloids, iibhaktheriya, kunye neemolekyuli ezinkulu zezinto eziphilayo.

-Izinto ezilungileyo zibandakanya izinga eliphezulu lokubuyisela amanzi, ukucocwa lula kunye nokubuyisela emva, ixesha elide lokuphila, kunye neendleko zokusebenza eziphantsi.

4. **I-Nanofiltration (NF):**
-Ukuchaneka kohluzo kuphakathi kwe-UF kunye ne-RO. Ifuna umbane kunye noxinzelelo lwetekhnoloji yokwahlula inwebu. Inokususa i-calcium kunye ne-magnesium ion kodwa isenokungazisusi ngokupheleleyo iiyoni eziyingozi.

– Ukungalungi kubandakanya izinga lokubuyisela amanzi aphantsi kunye nokungakwazi ukucoca izinto ezithile ezinobungozi.

5. **Reverse Osmosis (RO):**
-Ukuchaneka okuphezulu kokucoca malunga ne-0.0001 microns. Ingahluza phantse bonke ukungcola kuquka ibhaktheriya, iintsholongwane, iintsimbi ezinzima, kunye namayeza okubulala iintsholongwane.

-Izinto eziluncedo zibandakanya izinga eliphezulu le-desalination, amandla aphezulu omatshini, ubomi obude, kunye nokunyamezela kwiimpembelelo zemichiza kunye nebhayoloji.

Ngokubhekiselele kwisakhono sokuhluza, umgangatho uqhelekile yiMicrofiltration> Ultrafiltration> Nanofiltration> Reverse Osmosis. Zombini i-Ultrafiltration kunye ne-Reverse Osmosis zikhetho ezifanelekileyo ngokuxhomekeke kwizinto ezikhethwayo. I-Ultrafiltration ilungile kwaye inexabiso eliphantsi kodwa ayinakutyiwa ngokuthe ngqo. I-Reverse Osmosis ilungele iimfuno zomgangatho wamanzi aphezulu, njengokwenza iti okanye ikofu, kodwa inokufuna amanyathelo ongezelelweyo okusetyenziswa. Kuyacetyiswa ukuba ukhethe ngokweemfuno zakho kunye nezinto ozikhethayo.
