PH tswj cov ntsiab cai nyob rau hauv ntau theem ntawm Reverse Osmosis Operation
Rov qab Osmosis (RO) thev naus laus zis tau dhau los ua lub hauv paus hauv kev kho dej niaj hnub, siv dav hauv kev lag luam, hauv nroog, thiab kev lag luam. Ib qho ntawm cov kev ua haujlwm tseem ceeb hauv kev ua haujlwm ruaj khov thiab tiv thaiv RO daim nyias nyias yog tswj pH. Kev tswj hwm pH kom zoo thaum lub sijhawm sib txawv ntawm RO kev ua haujlwm-pretreatment, kev ua haujlwm, thiab tu-tshwj xeeb cuam tshuam rau kev ua haujlwm ntawm lub cev, dej zoo, thiab lub neej ntev ntawm daim nyias nyias.
Qhov tseem ceeb ntawm pH hauv RO Systems
RO daim nyias nyias yog rhiab heev rau pH siab heev. Thaum feem ntau polyamide thin-film composite (TFC) daim nyias nyias tuaj yeem ua haujlwm nyob rau hauv thaj tsam pH ntawm 4-11, cov txheej txheem tu lub sij hawm luv luv tso cai rau ntau qhov dav (feem ntau pH 2-12). Yog tias pH tsis raug tswj xyuas kom zoo, ntsuas qhov ntsuas, fouling, lossis hydrolysis ntawm cov khoom siv hauv daim nyias nyias tuaj yeem tshwm sim, txo cov ntsev tsis kam thiab ua kom lub neej ua haujlwm luv.
pH tswj nyob rau theem sib txawv
- Pretreatment Theem
- Lub hom phiaj: Tiv thaiv scaling thiab fouling hauv RO system.
- Txoj kev: Kho feedwater pH kom txo tau nag lossis daus los ntawm hardness ions xws li calcium carbonate, calcium sulfate, los yog silica. Piv txwv li, kev siv cov kua qaub (sulfuric lossis hydrochloric acid) feem ntau yog siv los txo pH, yog li ua kom cov ntsev soluble thiab txo qhov scaling.
- Kev ua haujlwm theem
- Lub hom phiaj: Ua kom pom kev desalination kev ua tau zoo thaum tiv thaiv daim nyias nyias.
- Txoj kev: Thaum lub sijhawm ua haujlwm, cov dej pH khaws cia ruaj khov nyob rau hauv qhov kev pom zoo ntawm cov chaw tsim khoom membrane. Kev ruaj ntseg ua kom ntseeg tau tias cov txheej txheem polyamide ua kom nws txoj kev ntseeg ruaj khov, ua tiav cov ntsev tsis kam thiab cov dej permeate zoo ib yam.
- Theem Ntxuav (CIP – Clean-In-Place)
- Lub hom phiaj: Tshem tawm cov nplais loj, cov fouling organic, lossis kev loj hlob lom.
- Txoj kev:
- Cov tshuaj ntxuav cov kua qaub (pH qis, nyob ib ncig ntawm 2-4) dissolve inorganic scaling xws li calcium carbonate los yog hlau deposits.
- Alkaline ntxuav kev daws teeb meem (pH siab, nyob ib ncig ntawm 10-12) tshem tawm cov organic fouling, roj, thiab cov khoom lom.
Hloov ntawm acidic thiab alkaline ntxuav kom tag nrho cov txheej txheem rov qab tsis ua rau daim nyias nyias.

Xaus
pH tswj yog qhov tseem ceeb hauv txhua theem ntawm kev ua haujlwm rov qab osmosis. Los ntawm kev tiv thaiv scaling nyob rau hauv pretreatment, kom ruaj khov kev ua tau zoo thaum lub sij hawm ua hauj lwm, kom zoo tshuaj ntxuav, tswj qhov tseeb pH ntau yam kev tiv thaiv ob qho tib si dej zoo thiab lub neej ntev ntawm RO daim nyias nyias. HID MEMBRANE CO., LTD. txuas ntxiv txhawb kev lag luam thoob ntiaj teb nrog cov txheej txheem membrane siab tshaj plaws thiab cov kws tshaj lij kev paub, pab cov neeg siv khoom kom ua tiav cov kev daws teeb meem dej nyab xeeb thiab raug nqi zoo.
