4. Tsis siv neeg tswj qhov system: Lub tshuab tswj tsis siv neeg ua haujlwm los saib xyuas thiab kho cov xwm txheej ua haujlwm ntawm cov khoom siv rov qab osmosis kom ntseeg tau tias cov khoom siv muaj kev nyab xeeb thiab ua haujlwm zoo. Hom no feem ntau suav nrog PLC (programmable controller), kov zaub, sensors, thiab cov khoom siv.

5. Cov txheej txheem tom qab kev kho mob: Cov txheej txheem tom qab kev kho mob txuas ntxiv tsim thiab ua cov dej uas tshwm sim los ntawm RO rov qab osmosis kom ua tau raws li cov qauv ntsuas dej zoo rau ntau lub hom phiaj. Cov kev kho mob tom qab ntau tshaj plaws suav nrog ultraviolet sterilization, ozone sterilization thiab activated carbon filtration.

3.Cov ntawv thov kev lag luam ntawm thim rov qab osmosis cog.

1. Cov dej muaj dej: cov khoom siv rov qab osmosis tau siv dav hauv kev lag luam, suav nrog hluav taws xob engineering, khoom siv hluav taws xob, tshuaj nroj tsuag, kev lag luam tshuaj thiab lwm yam haujlwm. Qhov kev thov rau cov dej hauv cov teb no yog nruj heev, thiab nws yog ib qho tsim nyog yuav tsum tshem tawm txhua yam impurities thiab cations hauv dej kom tsim nyog los xyuas kom meej qhov ruaj khov ntawm cov txheej txheem thiab cov khoom zoo.

2. Kev kho dej huv hauv tsev: Nrog kev txhim kho ntawm tib neeg txoj kev muaj peev xwm ua neej nyob, tib neeg txoj cai ntawm cov dej haus tau nce zuj zus ib hnub. Cov khoom siv rov qab osmosis tuaj yeem tshem tawm cov pa phem xws li impurities, kab mob thiab cov hlau hnyav hauv dej, yog li txhim kho kev nyab xeeb ntawm cov dej haus. Nyob rau theem no, ntau tsev neeg tau teeb tsa tsev neeg rov qab osmosis dej purifiers kom paub meej txog kev noj qab haus huv thiab kev nyab xeeb ntawm cov dej haus.

3. Seawater desalination cov cuab yeej yog ib txoj hauv kev tseem ceeb los daws cov dej paug thoob ntiaj teb.
