Uma ukhetha umshini wokuhlanza amanzi ngaphansi kwesinki, kunezindlela eziningana okufanele uzicabangele:

1. **Uhlobo Lokuhlanza Amanzi:**
– Kunezinhlobo eziningana ezitholakalayo okuhlanganisa i-Microfiltration (MF), i-Ultrafiltration (UF), i-Nanofiltration (NF), kanye ne-Reverse Osmosis (RO). Uma ukhetha, cabanga ngobuchwepheshe bokuhlunga, ukusebenza kahle kwesihlungi, ukulula kokushintshana kwekhatriji, isikhathi sokuphila, kanye nezindleko zokufaka esikhundleni.

2. **Ukuhlunga nge-Microfiltration (MF):**
– Ukunemba kokuhlunga kuvame ukuba phakathi kwama-micron angu-0.1 kuya kwangu-50. Izinhlobo ezivamile zifaka phakathi ama-cartridges okuhlunga e-PP, ama-cartridges okuhlunga e-carbon asebenzayo, kanye nama-cartridges okuhlunga e-ceramic. Asetshenziselwa ukuhlunga okuqinile, ukususa izinhlayiya ezinkulu njenge-sediment kanye nokugqwala.

– Okubi kufaka phakathi ukungakwazi ukususa izinto eziyingozi njengebhaktheriya, ukungakwazi ukuhlanza amakhatriji okuhlunga (avame ukulahlwa), kanye nokushintshwa njalo.

3. **Ukuhlunga Okunamandla (UF):**
– Ukunemba kokuhlunga kusuka kuma-micron angu-0.001 kuya ku-0.1. Isebenzisa ubuchwepheshe bokuhlukanisa ulwelwesi lomehluko wokucindezela ukususa ukugqwala, inhlabathi, ama-colloid, amabhaktheriya, nama-molecule amakhulu e-organic.

– Izinzuzo zifaka phakathi izinga eliphezulu lokutakula amanzi, ukuhlanza okulula nokuwasha ngemuva, isikhathi eside sokuphila, kanye nezindleko zokusebenza eziphansi.

4. **Ukuhlunga nge-Nano (NF):**
– Ukunemba kokuhlunga kuphakathi kwe-UF ne-RO. Kudinga ugesi kanye nengcindezi yobuchwepheshe bokuhlukanisa i-membrane. Kungasusa ama-ion e-calcium ne-magnesium kodwa kungase kungasusi ngokuphelele amanye ama-ion ayingozi.

– Okubi kufaka phakathi izinga eliphansi lokululama kwamanzi kanye nokungakwazi ukuhlunga izinto ezithile eziyingozi.

5. **I-Reverse Osmosis (RO):**
– Ukunemba okuphezulu kakhulu kokuhlunga okungama-micron angu-0.0001. Ingahlunga cishe konke ukungcola okuhlanganisa amabhaktheriya, amagciwane, izinsimbi ezisindayo, kanye nama-antibiotic.

– Izinzuzo zifaka phakathi izinga eliphezulu lokukhipha usawoti emanzini, amandla aphezulu okusebenza, isikhathi eside sokuphila, kanye nokubekezelela amathonya amakhemikhali kanye ne-biological.

Ngokuphathelene nekhono lokuhlunga, izinga livame ukuba yi-Microfiltration > Ultrafiltration > Nanofiltration > Reverse Osmosis. Kokubili i-Ultrafiltration kanye ne-Reverse Osmosis kuyizinketho ezifanele kuye ngokuthanda kwakho. I-Ultrafiltration ilula futhi ishibhile kodwa ayikwazi ukudliwa ngqo. I-Reverse Osmosis ilungele izidingo zekhwalithi ephezulu yamanzi, njengokwenza itiye noma ikhofi, kodwa ingadinga izinyathelo ezengeziwe zokusetshenziswa. Kunconywa ukuthi ukhethe ngokwezidingo zakho ezithile kanye nezintandokazi zakho.
