Xa ukhetha isixhobo sokucoca amanzi esingaphantsi kwesinki, kukho iinkalo ezininzi ekufuneka ziqwalaselwe:

1. **Uhlobo lweSicoci samanzi:**
– Kukho iintlobo ezahlukeneyo ezikhoyo eziquka iMicrofiltration (MF), iUltrafiltration (UF), iNanofiltration (NF), kunye neReverse Osmosis (RO). Xa ukhetha, cinga ngetekhnoloji yokucoca, ukusebenza kakuhle kwesihluzo, ukulula kokutshintshwa kwekhatriji, ubomi obude, kunye neendleko zokutshintsha.

2. **Ukucoca ngeMicrofiltration (MF):**
– Ukuchaneka kokuhluza kudla ngokuba phakathi kwe-0.1 ukuya kwi-50 microns. Iindidi eziqhelekileyo ziquka iikhatriji zesihluzi se-PP, iikhatriji zesihluzi sekhabhoni esebenzayo, kunye neekhatriji zesihluzi se-ceramic. Zisetyenziselwa ukuhluza okurhabaxa, ukususa amasuntswana amakhulu anjenge-sediment kunye ne-rust.

– Izinto ezingalunganga ziquka ukungakwazi ukususa izinto ezinobungozi ezifana neebhaktheriya, ukungakwazi ukucoca iikhatriji zesihluzo (ezidla ngokulahla), kunye nokutshintshwa rhoqo.

3. **Ukucoca nge-Ultra (UF):**
– Ukuchaneka kokuhluza kususela kwi-0.001 ukuya kwi-0.1 microns. Isebenzisa iteknoloji yokwahlulahlula i-membrane yoxinzelelo ukususa umhlwa, i-sediment, ii-colloids, iibhaktheriya, kunye neemolekyuli ezinkulu ze-organic.

– Iingenelo ziquka izinga eliphezulu lokubuyisa amanzi, ukucocwa nokuhlanjwa umva okulula, ixesha elide lokusebenza, kunye neendleko zokusebenza eziphantsi.

4. **Ukucoca ngeNano (NF):**
– Ukuchaneka kokuhluza kuphakathi kwe-UF kunye ne-RO. Ifuna umbane kunye noxinzelelo kwitekhnoloji yokwahlula i-membrane. Ingasusa i-calcium kunye ne-magnesium ions kodwa isenokungazisusi ngokupheleleyo ezinye ii-ion eziyingozi.

– Iingxaki ziquka izinga eliphantsi lokubuyisa amanzi kunye nokungakwazi ukucoca izinto ezithile eziyingozi.

5. **I-Osmosis Ebuyela Umva (RO):**
– Ukuchaneka okuphezulu kokuhluza malunga ne-0.0001 microns. Ingahluza phantse yonke into engcolileyo kuquka iibhaktheriya, iintsholongwane, iimetal ezinzima, kunye nee-antibiotics.

– Iingenelo ziquka izinga eliphezulu lokukhupha ityuwa emanzini, amandla aphezulu oomatshini, ixesha elide lokuphila, kunye nokunyamezela iimpembelelo zeekhemikhali nezebhayoloji.

Ngokuphathelele amandla okucoca, uluhlu ludla ngokuba yiMicrofiltration > Ultrafiltration > Nanofiltration > Reverse Osmosis. Zombini i-Ultrafiltration kunye ne-Reverse Osmosis zikhetho ezifanelekileyo kuxhomekeke kwizinto ozikhethayo. I-Ultrafiltration ilula kwaye ingabizi kakhulu kodwa ayinakutyiwa ngokuthe ngqo. I-Reverse Osmosis ilungele iimfuno zomgangatho ophezulu wamanzi, njengokwenza iti okanye ikofu, kodwa inokufuna amanyathelo ongezelelweyo okusela. Kucetyiswa ukuba ukhethe ngokweemfuno zakho kunye nezinto ozikhethayo.
