Sediment and Carbon Prefilters: Karya da fouling da chlorine damage

Koƙarin yadda ake amfani da shi na mafi kyau shi ne kuma yadda ake gudanar da shi na farko don ƙananen RO. Koƙari na tsakiya da koƙari na karbon suna aiki ta hanyar tashin kuma suka gudanar da karamin tashin thin-film composite (TFC). Koƙari na tsakiya ta 5-micron ta sanya abubuwan da suka ƙare—sabun, silt, rust, da sauran abubuwan da suka ƙare—wanda za suka cire kwayoyin da suka ƙare na spiral-wound na membrane. Idan a ba su gudanarwa, wannan yana zama sabonin yadda ake cire pressure drop, kara yadda ake furo, kara yadda ake gudanar da shi, kara yadda ake amfani da energy, da kuma kara yadda ake gudanar da shi na karamin surface.

A cikin wani lokaci ta farko, koƙari na karbon ta amfani da chlorine, chloramines, da abubuwan da suka ƙare na organic. Abubuwan da suka ƙare na municipal suna da chlorine ta 0.2–1.0 ppm—a known oxidant wanda ke cire polyamide TFC membranes. Oxidation ta cire yadda ake gudanar da salt rejection da kuma ta kara yadda ake gudanar da shi. kawai sunan su zama ga membrane yana kara selectivity kuma yana ƙarƙashin zaman da aka fiye da 50% ko kuma yana ƙarƙashin zaman. Al'amarin daga wani ƙasar na gaba mai amfani na RO yana nuna cewa dual-stage prefiltration yana ƙarƙashin zaman da aka fiye da 50% ko kuma. Don kara kula da aminci, ku bi pressure drop a tsakanin sediment filter kuma ku ji chlorine breakthrough a carbon outlet; ku saha abubuwan da suka cika (cartridges) douni a kowane 6 zuwa 12 months ta hanyar amfani da su kuma kwalitasin ruwa da aka shiga.

High-Pressure Booster Pump (60+ PSI) da Precision Pressure Gauges

Kamarun yadda wani mutum ya sake so, yana ba da 40–50 PSI kuma yana ƙasa da 60 PSI wanda ke bukatar suka amfani da RO membrane. A lokacin da aka yi amfani da pressure mai ƙarfi, yana zama ƙarfi mai ƙarfi wanda yana cire output na permeate don 35% kuma yana cire TDS rejection don 5–7%, a matsayin analisis na International Water Association na 2022. A high-pressure booster pump yana taimaka wajen cire feed pressure zuwa 60–80 PSI, wanda ke da adjustable bypass control. Ku bi models da ke da dry-run protection da kuma compact under-sink designs.

Precision pressure gauges suna ba da bayani daidai: wani daga su ya kashe a baya na membrane housing yana nuna feed pressure, kuma wani na biyu a cikin permeate side yana taimaka wajen gano early fouling ta hanyar rising differential pressure. A matsayin kuma pump da gauges, suna taimaka wajen kare flux da rejection, suna taimaka wajen kare system recovery don 15–25%, kuma suna cire mechanical stress a cikin membrane—wanda ke taimaka wajen kare service life da kuma performance mai kyau.
