Lokacin zabar mai tsabtace ruwa a ƙarƙashin nutsewa, akwai sigogi da yawa don la'akari:

1. **Nau'in Mai Tsarkake Ruwa:**
Akwai nau'ikan nau'ikan da yawa waɗanda suka haɗa da Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), da Reverse Osmosis (RO). Lokacin zabar, yi la'akari da fasahar tacewa, ingancin tacewa, sauƙi na maye gurbin harsashi, tsawon rayuwa, da farashin sauyawa.

2. **Microfiltration (MF):**
- Madaidaicin tacewa yawanci jeri daga 0.1 zuwa 50 microns. Nau'o'in gama-gari sun haɗa da harsashin tacewa na PP, kunnuwa masu tace carbon da aka kunna, da harsashin tace yumbu. Ana amfani da shi don tacewa mai ƙarfi, cire manyan barbashi kamar laka da tsatsa.

- Lalacewar sun haɗa da rashin iya cire abubuwa masu cutarwa kamar ƙwayoyin cuta, rashin iya tsaftace harsashin tacewa (sau da yawa ana iya zubarwa), da sauyawa akai-akai da ake buƙata.

3. **Ultrafiltration (UF):**
- Madaidaicin tacewa daga 0.001 zuwa 0.1 microns. Yana amfani da fasahar rabuwar matsi don cire tsatsa, laka, colloids, kwayoyin cuta, da manyan kwayoyin halitta.

- Abubuwan amfani sun haɗa da ƙimar dawo da ruwa mai yawa, sauƙin tsaftacewa da wankewa, tsawon rayuwa, da ƙarancin farashin aiki.

4. **Nanofiltration (NF):**
- Madaidaicin tacewa tsakanin UF da RO. Yana buƙatar wutar lantarki da matsa lamba don fasahar rabuwar membrane. Zai iya cire ions na calcium da magnesium amma maiyuwa baya cire wasu ions masu cutarwa gaba ɗaya.

- Rashin lahani sun haɗa da ƙarancin dawo da ruwa da rashin iya tace wasu abubuwa masu cutarwa.

5. ** Reverse Osmosis (RO):**
- Madaidaicin tacewa na kusan 0.0001 microns. Zai iya tace kusan duk ƙazanta da suka haɗa da ƙwayoyin cuta, ƙwayoyin cuta, ƙarfe masu nauyi, da maganin rigakafi.

- Abubuwan amfani sun haɗa da yawan zubar ruwa mai yawa, ƙarfin injina, tsawon rayuwa, da juriya ga tasirin sinadarai da ilimin halitta.

Dangane da iyawar tacewa, martaba shine yawanci Microfiltration> Ultrafiltration> Nanofiltration> Reverse Osmosis. Dukansu Ultrafiltration da Reverse Osmosis zaɓi ne masu dacewa dangane da abubuwan da aka zaɓa. Ultrafiltration ya dace kuma maras tsada amma ba za a iya cinye shi kai tsaye ba. Reverse Osmosis ya dace don buƙatun ingancin ruwa, kamar don yin shayi ko kofi, amma yana iya buƙatar ƙarin matakai don amfani. Ana ba da shawarar zaɓi bisa ga takamaiman buƙatunku da abubuwan da kuka zaɓa.
