Rov qab osmosis (RO) daim nyias nyias, raws li cov ntsiab lus tseem ceeb ntawmCov khoom siv kho dej, ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw vim lawv cov txiaj ntsig zoo, muaj txiaj ntsig zoo, thiab tus phooj ywg ib puag ncig. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev tshwm sim ntawm cov ntaub ntawv tshiab, thev naus laus zis rov qab osmosis tau nce zuj zus los daws cov teeb meem kev kho dej, muab tib neeg nrog kev nyab xeeb thiab ruaj khov dej ntau dua. Los ntawm kev txheeb xyuas qhov tob, nws pom tseeb tias RO membrane tuav txoj haujlwm tseem ceeb hauv kev kho dej. Nws tsis tsuas yog txhawb nqa cov qauv dej zoo xwb tab sis kuj tseem txhawb kev tsim kho tshiab thiab kev vam meej hauv kev kho dej thev naus laus zis tag nrho. Tsav los ntawm kev paub ntau ntxiv txog kev txuag dej, kev siv thev naus laus zis rov qab osmosis yuav dhau los ua qhov dav zuj zus, ua rau muaj txiaj ntsig zoo rau kev siv dej thoob ntiaj teb.
Yuav ntsuas qhov ua tau zoo ntawm Reverse Osmosis Membranes li cas? Feem ntau, kev ua tau zoo ntawm rov qab osmosis (RO) daim nyias nyias yog ntsuas los ntawm peb lub ntsiab lus tseem ceeb: tus nqi rov qab, tus nqi dej ntau lawm (thiab flux), thiab tus nqi tsis kam ntsev.
1. Tus nqi rov qab
Tus nqi rov qab yog qhov taw qhia tseem ceeb ntawm kev ua haujlwm ntawm RO membrane lossis system. Nws sawv cev rau qhov kev faib ua feem ntawm cov dej pub hloov mus rau hauv cov khoom siv dej (cov dej huv). Cov mis yog: Rov qab Tus Nqi (%) = (Cov Khoom Siv Dej ntws ntws ÷Feed Dej Flow Rate) × 100
2. Dej ntau lawm thiab Flux
Dej Ntau Lawm: Hais txog qhov ntim ntawm cov dej huv uas tsim los ntawm RO membrane ib lub sijhawm nyob rau hauv cov xwm txheej tshwj xeeb. Cov chav nyob muaj xws li GPD (gallons ib hnub) thiab LPH (liters ib teev).
Flux: Qhia txog qhov ntim ntawm cov dej uas ua rau ib cheeb tsam ntawm daim nyias nyias ib lub sij hawm. Cov chav nyob feem ntau yog GFD (gallons ib square feet ib hnub) lossis m³ / m²·hnub (cubic meters ib square meter ib hnub).
Formula: Dej Ntau Lawm = Flux × Zoo Membrane Area
3. Ntsev Rejection Rate
Tus nqi tsis kam ntsev qhia txog lub peev xwm ntawm aRov qab osmosis (RO)membrane kom tshem tawm impurities los ntawm dej. Feem ntau, kev tshem tawm kev ua haujlwm ntawm RO membranes rau cov kab mob tshwj xeeb ua raws li cov qauv no:
Kev tsis lees paub ntau dua rau polyvalent ions piv rau monovalent ions.
Qhov kev tshem tawm ntawm cov ions nyuaj yog siab dua li cov ions yooj yim.
Kev tshem tawm qis dua rau cov organic tebchaw nrog qhov hnyav molecular hauv qab 100.
Txo kev ua tau zoo tiv thaiv cov ntsiab lus nitrogen-pab pawg thiab lawv cov tebchaw.
Tsis tas li ntawd, tus nqi tsis kam ntsev yog categorized ua ob hom:
Pom meej Salt Rejection Rate:
Pom meej qhov tsis lees paub tus nqi (%) = 1-(Cov Khoom Siv Dej Ntsej Muag / Pub Dej Ntsev Concentration)
Tus nqi ntsev Rejection tiag tiag:
Tus nqi tsis lees paub qhov tseeb (%) = 1-2x Cov Khoom Siv Dej ntsev Concentration / (Feed Dej ntsev Concentration + Concentrate ntsev Concentration)] ÷2 × A
A: Concentration polarization factor (feem ntau ntawm 1.1 txog 1.2).
Qhov kev ntsuas no ua tiav ntsuas lub membrane cov impurity tshem tawm kev ua haujlwm raws li kev ua haujlwm tiag tiag hauv ntiaj teb.
