Cov teeb meem tshwm sim hauv Reverse Osmosis Membrane Operation (Part 2)
- Siab TDS Qib
Siab tag nrho yaj yaj (TDS) qib nyob rau hauv cov khoom dej qhia tias daim nyias nyias tsis zoo tshem tawm cov kab mob. Qhov no tuaj yeem yog vim cov membrane fouling, scaling, los yog puas daim nyias nyias. Kev saib xyuas thiab saib xyuas tsis tu ncua yog qhov tseem ceeb los khaws TDS qib hauv kev txheeb xyuas.
- Kev hloov pauv tsis tu ncua
Yog tias cov ntxaij lim dej yuav tsum tau hloov ntau zaus dua li niaj zaus, nws tuaj yeem yog vim cov dej tsis zoo los yog lub cev tsis zoo. Ua kom muaj kev kho mob ua ntej kom zoo thiab xaiv qhov system loj tuaj yeem pab txo qhov zaus ntawm kev hloov lim dej.
- Biofouling
Biofouling tshwm sim thaum cov kab mob xws li kab mob thiab algae loj hlob ntawm daim nyias nyias. Qhov no tuaj yeem ua rau clogging thiab txo efficiency. Kev tu tsis tu ncua nrog biocides thiab tswj kom huv huv ntawm cov dej pub tuaj yeem pab tiv thaiv biofouling.
- Tshuaj tua kab mob
Qee yam tshuaj, xws li tshuaj chlorine, tuaj yeem ua rau RO daim nyias nyias, ua rau txo qis kev ua haujlwm thiab kev ua neej. Siv cov txheej txheem dechlorination, xws li cov lim dej lim dej ua ntej, ua ntej cov dej mus txog RO membrane tuaj yeem tiv thaiv nws los ntawm tshuaj tua kab mob.
- Siab poob
Ib qho tseem ceeb poob siab nyob rau hauv daim nyias nyias yuav qhia tau tias fouling los yog scaling. Kev saib xyuas qhov sib txawv ntawm qhov siab thiab ua haujlwm tsis tu ncua tuaj yeem pab txheeb xyuas thiab hais txog lub hauv paus ua rau lub siab poob.
- Membrane Aging
Thaum lub sij hawm, RO daim nyias nyias ib txwm degrade thiab poob lawv cov hauj lwm zoo. Qhov no tuaj yeem ua rau cov dej tsis zoo thiab txo cov nqi ntws. Kev hloov pauv cov membrane tsis tu ncua yog qhov tseem ceeb los tswj kev ua haujlwm ntawm lub cev.
- Kev kho tsis zoo
Kev kho cov dej tsis zoo tuaj yeem ua rau muaj ntau yam teeb meem, suav nrog fouling, scaling, thiab biofouling. Ua kom zoo pretreatment, xws li sediment filtration, softening, thiab pH hloov, tuaj yeem txhim kho lub neej ntev thiab kev ua haujlwm ntawm RO membrane.
