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 kokuhlunga 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 ezilungileyo zibandakanya izinga eliphezulu lokukhupha ityuwa, amandla aphezulu omatshini, ixesha elide lokuphila, 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 ezikumgangatho ophezulu wamanzi, ezifana nokwenza iti okanye ikofu, kodwa inokufuna amanyathelo ongezelelweyo okusetyenziswa.Kuyacetyiswa ukuba ukhethe ngokweemfuno zakho kunye nezinto ozikhethayo.
