Nanofiltration membranes feem ntau yog them rau daim nyias nyias, nrog cov nqi tsis zoo ntawm qhov chaw, uas tuaj yeem cuam tshuam cations nrog ntau tshaj ob lub valences hauv dej thiab khaws cov monovalent ions (xws li sodium ions thiab potassium ions).Yog li ntawd, nanofiltration membranes khaws qee cov zaub mov hauv dej.Khoom siv.
Ntawm cov khoom hnyav hlau hnyav, arsenic feem ntau muaj nyob hauv dej li trivalent arsenic ions thiab pentavalent arsenic ions;chromium feem ntau muaj nyob rau hauv daim ntawv ntawm trivalent thiab hexavalent ions nyob rau hauv qhov.Yog li cov nanofiltration membrane tseem tuaj yeem lim tawm feem ntau ntawm cov hlau hnyav.Nws tseem tuaj yeem tshem tawm ib feem ntawm calcium thiab magnesium, yog li nws muaj qee yam cuam tshuam hauv softening dej nyuaj.
Nyob rau tib lub sijhawm, nanofiltration membranes tuaj yeem txo cov organic teeb meem hauv dej thiab carcinogens xws li trihalomethanes uas tsim thaum lub sij hawm chlorination thiab tshuaj tua kab mob ntawm cov dej haus.
Tus kab mob me tshaj plaws uas paub muaj lub cheeb ntawm 18nm-22nm (cov ntaub ntawv los ntawm Wikipedia).Piv nrog rau qhov pore loj ntawm nanofiltration membranes ntawm 1-2nm, cov kab mob thiab cov kab mob no kuj loj, yog li nanofiltration membranes yuav ua tau zoo tshem tawm cov kab mob thiab cov kab mob tsis zoo li nyuaj rau xav txog.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm nanofiltration membrane yog ib feem zoo ib yam li cov rov qab osmosis membrane.Lub siab nws dais yog qis dua qhov rov qab osmosis membrane, yog li nws tsim cov dej khib nyiab tsawg dua li rov qab osmosis membrane.
Ua ib qho ntawm thawj RO membranes tuam ntxhab nyob hauv Suav teb, HIDTMranks lub npe zoo tshaj plaws ntawm Suav RO membrane kev lag luam.Nanofiltration membranes tuaj yeem lim hlau ions saum toj no ob lub valences hauv dej (feem ntau, cov ntsiab lus ntawm monovalent ions hauv dej yog tsawg heev, thiab lawv yog tag nrho cov minerals uas muaj txiaj ntsig zoo rau tib neeg lub cev), thaum lub zog ua haujlwm ntawm nanofiltration membranes qis dua. thim rov qab osmosis daim nyias nyias, thiab cov dej tso tawm Nws yog ntau dua li rov qab osmosis daim nyias nyias thiab tuaj yeem tshem tawm cov calcium thiab magnesium ions uas yooj yim rau scale hauv dej.Kev siv cov nanofiltration membranes txaus los ua kom tau raws li cov kev xav tau ntawm cov dej haus.
- Nws yog ib qho kev xaiv zoo heev nanofiltration membrane cov khoom tsim tshwj xeeb tsim rau xoom-emission thiab kev siv peev txheej.
- Qhov kev tsis lees paub ntawm cov ion ntau ntau yog siab, qhov kev tsis lees paub ntawm cov ions monovalent tsawg, thiab qhov hnyav molecular txiav tawm yog qhov tseeb.
- Nws kuj yog tsim rau cov tshuaj analytical me me cais thiab Purification.
- Daim phiaj tshwj xeeb tsim tau txais yuav nyob rau hauv qhov dej ntws channel kom cov khoom muaj txiaj ntsig zoo dua hauv kev ua qias tuaj thiab yooj yim tu.
Nco tseg:
1. Cov kev ua haujlwm tsis raug ntsuas tom qab lub kaw lus ua haujlwm ruaj khov rau 30 feeb.2. Qhov sib txawv ntawm cov dej ntau lawm yog ± 15%.
2.1.5 Cov ntaub ntawv tseem ceeb
Kev pib kom raug yog qhov tseem ceeb rau kev ua haujlwm ruaj khov ntawm nanofiltration system.Ua ntej nanofiltration system yog debugged los yog restarted nyob rau hauv ib tug ntev-
Lub sijhawm kaw lub xeev, ntau yam khoom siv, ntsuas, thiab dej zoo yuav tsum tau kuaj xyuas thiab kho kom ntseeg tau tias txhua yam kev mob ua tau raws li cov kev teeb tsa lossis teeb tsa tus nqi
tom qab ua haujlwm.Thov xa mus rau phau ntawv qhia khoom rau cov kauj ruam ua haujlwm tshwj xeeb thiab ceev faj.
Txhawm rau tiv thaiv daim nyias nyias los ntawm kev khawb los ntawm cov khoom tawv, kev ruaj ntseg 5μm lim dej yuav tsum tsis txhob rov qab siv dua.
nkag.Thaum cov silicon concentration siab dhau lawm, 1μm kev ruaj ntseg lim tuaj yeem siv.Lub siab ntawm cov dej ntau lawm sab ntawm lub membrane module yuav tsum
Tsis txhob siab tshaj qhov siab ntawm cov dej pub mis txhua lub sijhawm, thiab lub siab zoo li qub yuav tsum tsawg dua 5 psi.
