PuasKev Kho Mob DejXyuas kom muaj kev lag luam ua haujlwm?
Muaj cov txheej txheem siv cov dej ua ke ntawm cov dej txhua hnub, los ntawm kev txias txias yees mus rau cov khoom yaug, tseem muaj cov khoom siv uas tsis muaj zog thiab cov khoom tsis zoo. Kev tsim cov dej kho cov dej kho mob Cov kev pheej hmoo no cov kev pheej hmoo no los ntawm kev ua kom muaj kev sib koom ua raws li ib puag ncig thaum muaj kev siv zog siv. Thev naus laus zis zoo liTus ro(thim rov qab osmosis) thiabMVR EvaporatorUa si pivotal cov luag hauj lwm: RO cais cov khib nyiab yaj ntawm membrane pom zoo, thaum rov ua kom sov li qub, ob leeg txo cov txiaj ntsig tsis zoo thiab muaj txiaj ntsig zoo los ntawm kev ua haujlwm.
Qhov kev sib xyaw ua ke no tsis tsuas yog cov nqi qis tab sis kuj hais txog kev tswj hwm kev tswj hwm kev ntsuas ntawm kev siv dej. Hauv qab no, peb tshawb txog kev siv cov txheej txheem, tiag- he} Lub ntiaj teb kev ua haujlwm, thiab pheej ua haujlwm hauv ntiaj teb, xa cov tswv yim tswv yim rau cov kws ua haujlwm enganticers thiab vaj tse.
Dab tsi yog Cheeb Tsam Kho Kom Kho cov tshuab?
Puas yog membrane thev naus laus zis siv tau kev ua kom huv?
Cov tub ntxhais nyob rau ntau lub teeb tsa, RO ua haujlwm semi- permentales nrog 0.0001}} pa pores kom tsis lees txais 95-99% ntawm cov paug tsis ua haujlwm hauv xyoo 200-400 PSI siab. Noolater hla dhau cov lim dej ua ntej (cov quav, carbon) ua ntej siv cov dej hauv qab, ua kom huv) cais tawm ntawm (brine).
